This appliance fixes gaps between the teeth, small spaces between the upper and lower jaw, and other minor problems.

General guidelines suggest brushing twice a day: after breakfast and before going to bed, but ideally the mouth would be cleaned after every meal. Cleaning between the teeth is called interdental cleaning and is as important as tooth brushing. This is because a toothbrush cannot reach between the teeth and therefore only removes about 50% of plaque from the surface of the teeth. There are many tools to clean between the teeth, including floss and interdental brushes; it is up to each individual to choose which tool they prefer to use.

Is a rare condition, categorised by tongue enlargement which will eventually create a crenated border in relation to the embrasures between the teeth.

The interdental plate refers to the bone-filled mesial-distal region between the teeth. The word "interdental" is a combination of "inter" + "dental" (meaning "between the teeth") which originated in approximately 1870. In paleobiology, the presence or absence of the interdental plate can determine the place of an animal in the evolutionary scale, and paleontologists use the interdental plate when trying to classify a new specimen. Thecodont reptiles and theropod dinosaur fossils have an interdental plate, whereas acrodont reptiles such as Sphenodontia do not.

In old age, cranial sutures may ossify (turn to bone) completely. The joints between the teeth and jaws (gomphoses) and the joint between the mandible and the cranium, the temporomandibular joint, form the only non- sutured joints in the skull.

T. tenax trophozoites survive in the body as mouth scavengers that feed primarily on local microorganisms located between the teeth, tonsillar crypts, pyorrheal pockets, and the gingival margin around the gums. T. tenax trophozoites multiply by longitudinal binary fission. These trophozoites are unable to survive the digestive process.

This is the most uncomfortable stage for the patient. Quick and gentle manipulation under vision guides the endoscope into the esophagus.

In 2003 the tooth (MGUH 27218/DK 315) was made the holotype specimen of Dromaeosauroides bornholmensis—named and described by Christiansen and Bonde. The genus name combines Dromaeosaurus with the Greek ("in the form of"), referring to the resemblance between the teeth of the two genera. The specific name refers to Bornholm.

Lingual papillae, particularly filiform papillae, are thought to increase the surface area of the tongue and to increase the area of contact and friction between the tongue and food. This may increase the tongue's ability to manipulate a bolus of food, and also to position food between the teeth during mastication (chewing) and swallowing.

At their margin, between the teeth, adventitious buds appear, which produce roots, stems and leaves. When the plantlets fall to the ground, they root and can become larger plants. This is a fairly common trait in the section Bryophyllum. The fruits are follicles (10–15 mm) which are found in the persistent calyx and corolla.

Brushing the teeth twice per day and flossing between the teeth once a day is recommended. Fluoride may be acquired from water, salt or toothpaste among other sources. Treating a mother's dental caries may decrease the risk in her children by decreasing the numbers of certain bacteria she may spread to them. Screening can result in earlier detection.

MB R 1091 also had less wrinkled tooth enamel. Buffetaut notes that these differences could be explained by individual variation within the taxon, but since both teeth originated from different members of the Tendaguru Formation, the referral is only tentative. Buffetaut elaborated on the differences between the teeth of Ostafrikasaurus crassiserratus and Janensch's L.? stechowi morphotypes.

It was also noted by D'Emic and his team that the differences between the teeth of the sauropods also indicated a difference in diet. Diplodocus ate plants low to the ground and Camarasaurus browsed leaves from top and middle branches. According to the scientists, the specializing of their diets helped the different herbivorous dinosaurs to coexist.

Comahuesuchidae is a family of notosuchian crocodyliforms. Constructed in 1991, it includes the genera Comahuesuchus and Anatosuchus. Among the characteristics that are unique to this family is an external naris that is inset into the tip of the snout. There is also a diastema, or gap between the teeth, at the tip of the upper and lower jaws.

The steps in using an interdental brush are as follows: # Identify the size required, the largest size that will fit without force is ideal, if necessary more than one size can be used. # Insert the bristles into the interdental space at a 90-degree angle. # Move the brush back and forth between the teeth. # Rinse under water to remove debris when necessary.

Shed hairs that accumulate between the teeth of the toothcomb are removed by the sublingua or "under-tongue". Lemuriforms also possess a grooming claw on the second digit of each foot for scratching. Adapiforms did not possess a toothcomb. Instead, their lower incisors varied in orientation – from somewhat procumbent to somewhat vertical – and the lower canines were projected upwards and were often prominent.

On the inner ends of the flange there are two tabs with enlarged ends, which are gripped between the teeth. These tabs also keep the teeth apart sufficiently to allow comfortable breathing through the gap. Most recreational diving regulators are fitted with a mouthpiece. In twin-hose regulators and rebreathers, "mouthpiece" may refer to the whole assembly between the two flexible tubes.

Anatomy of the mouth. Floor of the mouth with Lingual frenum and sublingual fold The mouth consists of 2 regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces.

Cheeks are fleshy in humans, the skin being suspended by the chin and the jaws, and forming the lateral wall of the human mouth, visibly touching the cheekbone below the eye. The inside of the cheek is lined with a mucous membrane (buccal mucosa, part of the oral mucosa). During mastication (chewing), the cheeks and tongue between them serve to keep the food between the teeth.

The specimen of choice for diagnosing Trichomonas tenax trophozoite is mouth scrapings. Microscopic examination of tonsillar crypts and pyorrheal pockets of patients suffering from T. tenax infections often yields the typical trophozoites. Tartar between the teeth and the gingival margin of the gums are the primary areas of the mouth that may also potentially harbor this organism. T. tenax may also be cultured onto appropriate media.

The second type is the diplolepidous peristome found in subclasses Bryidae, Funariidae, and Timmiidae. In this type, there are two rings of peristome teeth—an inner endostome (short for endoperistome) and an exostome. The endostome is a more delicate membrane, and its teeth are aligned between the teeth of the exostome. There are a few mosses in the Bryopsida that have no peristome in their capsules.

Because the ratchet can only stop backward motion at discrete points (i.e., at tooth boundaries), a ratchet does allow a limited amount of backward motion. This backward motion—which is limited to a maximum distance equal to the spacing between the teeth—is called backlash. In cases where backlash must be minimized, a smooth, toothless ratchet with a high friction surface such as rubber is sometimes used.

Toothbrushes with pointed rubber tips at the ends of the handles have been available for many years, and have more recently been replaced by a standalone tool called a gum stimulator designed to massage the gum line and the bases of the areas between the teeth. Such stimulators help to increase circulation to the gum line and to clear away bacteria which might not be removed by brushing and flossing alone.

Sometimes caries may be directly visible. However other methods of detection such as X-rays are used for less visible areas of teeth and to judge the extent of destruction. Lasers for detecting caries allow detection without ionizing radiation and are now used for detection of interproximal decay (between the teeth). Primary diagnosis involves inspection of all visible tooth surfaces using a good light source, dental mirror and explorer.

Dental radiographs (X-rays) may show dental caries before it is otherwise visible, in particular caries between the teeth. Large areas of dental caries are often apparent to the naked eye, but smaller lesions can be difficult to identify. Visual and tactile inspection along with radiographs are employed frequently among dentists, in particular to diagnose pit and fissure caries.Rosenstiel, Stephen F. Clinical Diagnosis of Dental Caries: A North American Perspective .

The hypoid pinion is then larger in diameter than an equivalent bevel pinion. A hypoid gear incorporates some sliding and can be considered halfway between a straight-cut gear and a worm gear. Special gear oils are required for hypoid gears because the sliding action requires effective lubrication under extreme pressure between the teeth. Hypoid gearings are used in power transmission products that are more efficient than conventional worm gearing.

A Stranger in Town (Italian: Un dollaro tra i denti, lit. "A dollar between the teeth"), released in the UK as For a Dollar in the Teeth, is a 1967 Italian-American Spaghetti Western film directed by Luigi Vanzi. The film is the first in a series of four western films starring Tony Anthony as "The Stranger". Released by MGM, it was a surprise box office hit in international markets.

In August 2012, the third album, The Bit Between The Teeth, was announced in an interview on a Canadian music site, with an official announcement detailing the band's single release on the record label's website in 2013. In the same announcement, the release date for the album was given as 8 April 2013. The band announced later in July that this album would be their last as Skint & Demoralised.

This includes twice-daily brushing with daily flossing. Also, the use of an interdental brush is helpful if space between the teeth allows. For smaller spaces, products such as narrow picks with soft rubber bristles provide excellent manual cleaning. Persons with dexterity problems, such as with arthritis, may find oral hygiene to be difficult and may require more frequent professional care and/or the use of a powered toothbrush.

The sublingua can extend below the end of the tongue and is tipped with keratinized, serrated points that rake between the front teeth. Among lemurs, the toothcomb is variable in structure. Among indriids (Indriidae), the toothcomb is less procumbent and consists of four teeth instead of six. The indriid toothcomb is more robust and wider, with shorter incisors, wider spaces between the teeth (interdental spaces), and a broader apical ridge.

When they do form, they often must be removed. If any additional teeth form—for example, fourth and fifth molars, which are rare—they are referred to as supernumerary teeth (hyperdontia). Development of fewer than the usual number of teeth is called hypodontia. There are small differences between the teeth of males and females, with male teeth along with the male jaw tending to be larger on average than female teeth and jaw.

Connolly serves as the chairman of the Great Ormond Street Hospital. Connolly is also a racing fanatic, owning four horses at a stable near the South Coast. His horses are Crimson Monarch, Tungsten Strike, Night Crescendo and Gaia Prince.Taking the bit between the teeth The Spectator He also has an interest in others 'horses through the formation of the Green Dot Partnership, a racehorse syndicate that raised £630,000 from Deloitte partners to buy yearlings.

A picture demonstrating the use of floss to remove dental plaque between the teeth Dental professionals recommend that a person floss once per day before or after brushing to reach the areas that the brush will not and allow the fluoride from the toothpaste to reach between the teeth.American Dental Association, "Floss and Other Interdental Cleaners". Accessed 12 April 2010. Floss is commonly supplied in plastic dispensers that contain 10 to 100 meters of floss.

The use of a louse comb is the most effective way to detect living lice. With both methods, special attention should be paid to the area near the ears and the nape of the neck. The use of a magnifying glass to examine the material collected between the teeth of the comb could prevent misdiagnosis. The presence of nits alone, however, is not an accurate indicator of an active head louse infestation.

The early flute: a practical guide, p.23. . Such as: : - (=) : tu-ru There are different ways of tonguing for the flute. Some flutists tongue between the teeth; others do it between the lips as if spitting; others do it behind the teeth in the roof of the mouth as with trill consonants. With this roof articulation the flutist thinks of the words dah-dah and for double tonguing it is dah-gah-dah-gah.

The labial fricatives often—perhaps usually—have lateral airflow, as occlusion between the teeth and lips blocks the airflow in the center, but nonetheless they are not considered lateral consonants because no language makes a distinction between the two. In some languages, the centrality of a phoneme may be indeterminate. In Japanese, for example, there is a liquid phoneme , which may be either central or lateral, resulting in /ro/ produced as either or .

Both the left foot and testicle were missing. Hitler's dental remains consisted of nine upper teeth with dental work connected by a gold bridge and part of a lower jawbone with 15 teeth (10 of them artificial); the latter was found loose in the oral cavity. The tip of the tongue was "firmly locked between the teeth of the upper and lower jaws." The alveolar processes of the mandible were broken with "ragged edges".

In carnivores, the superior buccal gland is large and discrete: the Zygomatic gland. During mastication (chewing), the cheeks and tongue between them serve to keep the food between the teeth. Some animals such as squirrels and hamsters use the buccal pouch to carry food or other items. Malar stripes of a Geopard cheetah In some vertebrates, markings on the cheek area, particularly immediately beneath the eye, often serve as important distinguishing features between species or individuals.

Model with cleave gag A more effective variant of the over-the-mouth gag is called the cleave gag. Instead of being tied over the person's mouth, the scarf or cloth is pulled between his or her teeth. While such a gag of thin material is not very effective, a thick scarf can be used to hold his or her mouth open. Cleave gags are difficult to remove as they are between the teeth, not over the mouth.

Mammalodon, with a length of , was smaller and more primitive than modern baleen whales. Unlike other baleen whales, Mammalodon had a blunt and rounded snout. The left maxilla–upper jaw–of specimen NMV P199986 preserved four premolars and three molars, and the space between the teeth (diastema) increased towards back into the mouth. The molars decreased in size back into the mouth, like in archeocetes, and the bottom jaw had two more molars than the upper jaw.

The arm moves and its movement may be described as a rotation around an instant center which shifts on a dedicated trajectory. The manufacturers propose different solutions for moving the arm, trying to maintain constant distance between the teeth to the film and generator. Also those moving solutions try to project the teeth arch as orthogonally as possible. It is impossible to select an ideal movement as the anatomy varies very much from person to person.

Supragingival biofilm is dental plaque that forms above the gums, and is the first kind of plaque to form after the brushing of the teeth. It commonly forms in between the teeth, in the pits and grooves of the teeth and along the gums. It is made up of mostly aerobic bacteria, meaning these bacteria need oxygen to survive. If plaque remains on the tooth for a longer period of time, anaerobic bacteria begin to grow in this plaque.

The alveoli were elliptical to almost circular, and all were larger than the bases of the teeth they contained, which may therefore have been loosely held in the jaws. Though the number of alveoli in the dentary would seem to indicate that the teeth were very crowded, they were rather far apart, due to the larger size of their alveoli. The jaws contained replacement teeth at various stages of eruption. The interdental plates between the teeth were very low.

Bonaparte originally classified Cromptodon as a galesaurid. In 1991, J. A. Hopson, pointed out a resemblance between the teeth of Cromptodon and juvenile Aleodon and reclassified Cromptodon as a Chiniquodontid. In 2003, Fernando Abdala and Norberto P. Giannini systematically described Chiniquodontidae and found both Cromptodon and Aleodon to fall outside of Chiniquodontidae as both lacked features their study found to be diagnostic of the family, although additional material was required to provide a definite taxonomic placement.

The reason for the waffle-iron design's good performance in this respect is that the distance between the teeth is the same in both the longitudinal and transverse directions and nearly the same in all directions in between. This makes the waffle-iron nearly isotropic to TEM waves in all these directions. Since any TEn0 mode wave can be decomposed into two TEM mode waves travelling in different diagonal directions, all TEn0 modes are affected nearly equally.Matthaei et al.

When infants are born with certain defects in these proteins, such as nephrin and CD2AP, their kidneys cannot function. People have variations in these proteins, and some variations may predispose them to kidney failure later in life. Nephrin is a zipper-like protein that forms the slit diaphragm, with spaces between the teeth of the zipper, big enough to allow sugar and water through, but too small to allow proteins through. Nephrin defects are responsible for congenital kidney failure.

Later studies identified close similarities between the teeth of tritylodontids and traversodontids, and tritylodontids were eventually thought to be descendants of traversodontids. Under this classification, which was widely accepted in the following decades, Tritylodontidae was previous considered to be part of Gomphodontia, a larger group within Cynognathia. The name Tritylodontoidea was previously used for the group, which traditionally included the families Diademodontidae, Trirachodontidae, Traversodontidae, and Tritylodontidae. More recently, tritylodontids have been reinterpreted as close relatives of mammals.

Illustration of the holotype skull and three teeth Its teeth can be described as large conical pegs with voluminous roots. They are few in number and well spaced. The conjunction of the animal's stout teeth, massive lower jaw, and broad rostrum are indicative of an primordially crushing apparatus. T. eurycephalus may have preyed upon other ichthyosaurs: a bony element (basisphenoid) observed to be clenched between the teeth of BMNH R1157 (its holotype) may in fact belong to a victim.

Kalaw Lagaw Ya and many other languages in North Queensland differ from most other Australian languages in not having a retroflexive series. The dental series th, nh, lh are always laminal (that is, pronounced by touching with the surface of the tongue just above the tip, called the blade of the tongue), but may be formed in one of three different ways, depending on the language, on the speaker, and on how carefully the speaker pronounces the sound. These are interdental with the tip of the tongue visible between the teeth, as in th in English; dental with the tip of the tongue down behind the lower teeth, so that the blade is visible between the teeth; and denti-alveolar, that is, with both the tip and the blade making contact with the back of the upper teeth and alveolar ridge, as in French t, d, n, l. The first tends to be used in careful enunciation, and the last in more rapid speech, while the tongue-down articulation is less common.

The PDL is a part of the periodontium that provides for the attachment of the teeth to the surrounding alveolar bone by way of the cementum. PDL fibres also provide a role in load transfer between the teeth and alveolar bone. (PDL fibres absorb and transmit forces between teeth and alveolar bone. It acts as an effective support during the masticatory function.)McCormack SW, Witzel U, Watson PJ, Fagan MJ, Gröning F. The Biomechanical Function of Periodontal Ligament Fibres in Orthodontic Tooth Movement.

In this way, the spring compression rotates the free gear until all of the backlash in the system has been taken out; the teeth of the fixed gear press against one side of the teeth of the pinion while the teeth of the free gear press against the other side of the teeth on the pinion. Loads smaller than the force of the springs do not compress the springs and with no gaps between the teeth to be taken up, backlash is eliminated.

A malocclusion is a misalignment or incorrect relation between the teeth of the two dental arches when they approach each other as the jaws close. The term was coined by Edward Angle, the "father of modern orthodontics", as a derivative of occlusion. This refers to the manner in which opposing teeth meet (mal- + occlusion = "incorrect occlusion"). The malocclusion classification is based on the relationship of the Mesiobuccal cusp of the maxillary first molar and the buccal groove of the mandibular first molar.

Proper oral hygiene requires regular brushing and flossing Oral hygiene is the practice of keeping one's mouth clean and free of disease and other problems (e.g. bad breath) by regular brushing of the teeth (dental hygiene) and cleaning between the teeth. It is important that oral hygiene be carried out on a regular basis to enable prevention of dental disease and bad breath. The most common types of dental disease are tooth decay (cavities, dental caries) and gum diseases, including gingivitis, and periodontitis.

However, after a rather large diastema with the beak, there were large batteries of cheek teeth on the sides of the jaws: the gaps between the teeth crowns were filled by the points of a second generation of replacement teeth, the whole forming a continuous surface. Contrary to the situation with some related species, a third generation of erupted teeth was lacking. There were twenty-two tooth positions in both lower and upper jaw, for a total of eighty-eight.

Measuring in length and in width, the leathery green leaves are oblong to obovate (egg-shaped) or truncate with a recessed midvein and mildly recurved margins, which are entire at the base and serrate towards the ends of the leaves. The sinuses (spaces between the teeth) are U-shaped and teeth are 1–2 mm long. The leaf underside is whitish with a reticulated vein pattern and a raised central midrib. The leaves sit on 2–5 mm long petioles.

The slider can also have a two-piece hinge assembly attaching the handle to the slider, with the base of the hinge under spring tension and with protruding pins on the bottom that insert between the zipper teeth. To move the zipper, the handle is pulled outward against spring tension, lifting the pins out from between the teeth as the slider moves. When the handle is released the pins automatically engage between the zipper teeth again. They are called "auto-lock sliders".

However, daleth (ד), ṭet (ט), lamed (ל), nūn (נ), tau (ת) are [linguals] separated by the mid-section of the tongue with the [emission of] sound; whereas zayin (ז), samekh (ס), ṣadi (צ), resh (ר), shin (ש) are [dental sounds] produced between the teeth by a tongue that is at rest.” In modern Ashkenazi, Sephardi, and Mizrahi poetry and folk music, as well as in the standard (or "standardised") Hebrew used in the Israeli media, an alveolar rhotic is sometimes used.

Counter-intuitively, it is the cast of the maxilla which moves relative to the cast of the mandible and the articulator. An articulator assists in the accurate fabrication of the biting surfaces of removable prosthodontic appliances (dentures), fixed prosthodontic restorations (implants, crowns, bridges, inlays and onlays) and orthodontic appliances. Used with skill it ensures correct interdigitation of the teeth and an anatomically functional biting plane. This means less occlusal adjustments before and after fitting dental appliances and fewer chronic conflicts between the teeth and the jaw joints.

It had wide gaps (diastema) between the teeth. Its teeth had one of the thickest enamel layers of any known baleen whale, 830–890 μm at the top and 350–380 μm at the base, which is also consistent with a shearing action. It had a crest on the mandible which may have supported proper musculature to pucker its lips. All baleen whales have in their mouth palatal sulci, which carry blood, between tooth sockets, which has generally thought to be indicative of baleen.

A monkey using mastication to process tough plant matter Chewing or mastication is the process by which food is crushed and ground by teeth. It is the first step of digestion, and it increases the surface area of foods to allow a more efficient break down by enzymes. During the mastication process, the food is positioned by the cheek and tongue between the teeth for grinding. The muscles of mastication move the jaws to bring the teeth into intermittent contact, repeatedly occluding and opening.

A butterfly gag is a wing-shaped gag that is usually inflatable by means of a rubber bulb. The central part fits behind the teeth to fill up the mouth, while the wings go between the teeth and the lips. The gag inflates in the shape of a butterfly. This kind of gag is very hard to keep in the wearer; the use of an O-ring in front of the gag strapped to the back of the head will hold the butterfly gag in place.

Grids were drawn, stratigraphic profiles were raised and each extracted remainder was labeled. As an example of thoroughness, samples of pollen were taken from the clay adhered between the teeth of the elephants, to get as close as possible to the existing environment during the accumulation of the remains. In 1973 Aguirre directed the systematic excavation of more than 200 m² around the Museum of Ambrona, built ten years earlier, necessary to correct the humidity that endangered it, recovering more fossils and lithic industry.

Dental plaque is a biofilm of microorganisms mostly bacteria but also fungi, that grows on surfaces within the mouth. It is a sticky colorless deposit at first, but when it forms tartar, it is often brown or pale yellow. It is commonly found between the teeth, on the front of teeth, behind teeth, on chewing surfaces, along the gumline, (supragingival) or below the gumline cervical margins (subgingival). Dental plaque is also known as microbial plaque, oral biofilm, dental biofilm, dental plaque biofilm or bacterial plaque biofilm.

Breathing from scuba is mostly a straightforward matter. Under most circumstances it differs very little from normal surface breathing. In the case of a full-face mask, the diver may usually breathe through the nose or mouth as preferred, and in the case of a mouth held demand valve, the diver will have to hold the mouthpiece between the teeth and maintain a seal around it with the lips. Over a long dive this can induce jaw fatigue, and for some people, a gag reflex.

OMD also refers to factors such as nonnutritive sucking behaviors, such as thumb sucking, clenching, bruxing, etc. that led to abnormal development of dentition and oral cavity. OMD in adult and geriatric populations are due to various neurological impairments, oral hygiene, altered functioning of muscles due to aging, systemic diseases, etc. Tongue thrusting is a type of orofacial myofunctional disorder, which is defined as habitual resting or thrusting the tongue forward and/or sideways against or between the teeth while swallowing, chewing, resting, or speaking.

The application process of spacers usually involves stringing floss through the rubber band and placing the spacer between the teeth. Some spacers are small metal spring clips that squeeze the teeth apart. There is some pressure throughout the process and some soreness after, but overall, the spacer application process is quite painless, although the patient may immediately start to feel pain from the pressure exerted on the teeth. Sometimes special orthodontic tools are used to stretch open the rubber bands, depending on how crowded the teeth are.

The skull of Riojasuchus Ornithosuchids can be identified by the presence of an arched diastema, a gap between the teeth at the front of the snout. When the jaw is closed, two large curved dentary (lower jaw) teeth fit into the diastema, which is positioned between the premaxilla and maxilla. There are two shallow depressions on the wall of the diastema to accommodate these teeth. The large dentary teeth of Ornithosuchus and Riojasuchus are placed behind a smaller procumbent dentary tooth that sticks out from the jaw.

Joel Asaph Allen first described the species as Isothrix rufodorsalis in 1899. Known as the "red-crested tree rat", this species was originally described as Isothrix rufodorsalis by American biologist Joel Asaph Allen in 1899, and was transferred to genus Diplomys in 1935 by George Henry Hamilton Tate. In 2005, its subfamily Echimyinae was revised by Louise Emmons from the Smithsonian Institution, and identified a number of unique features of this species, including the differences between the teeth of this species and others in genus Diplomys. This resulted in the establishment of monotypic genus Santamartamys.

This reassignment was based on the close similarity between the tricuspid teeth of these trilophosaurs and those of the newly named procolophonid Xenodiphyodon. Sues and Olsen also proposed a new generic name for T. jacobsi, Chinleogomphius, given that it was no longer considered to be related to Trilophosaurus. However, because Variodens and Tricuspisaurus are known primarily from teeth, it is difficult to determine their classification. The similarities between the teeth of Variodens and those of procolophonids may be convergent adaptations to a herbivorous diet, and do not necessarily indicate a close relationship.

H. repandum on sale at a market in Finland H. repandum is considered to be a good edible, having a sweet, nutty taste and a crunchy texture. Some consider it to be the culinary equivalent of the chanterelle. Author Michael Kuo gives it an edibility rating of "great" and notes that there are no poisonous lookalikes, and that H. repandum mushrooms are unlikely to be infested with maggots. Delicately brushing the cap and stipe of specimens immediately after harvest will help prevent soil from getting lodged between the teeth.

The rotor has no conductive windings or electrical connections; it consists of a solid disc of high tensile strength magnetic steel, with narrow slots cut in its circumference to create a series of narrow "teeth" that function as magnetic poles. The space between the teeth is filled with nonmagnetic material, to give the rotor a smooth surface to decrease aerodynamic drag. The rotor is turned at a high speed by an electric motor. The machine operates by variable reluctance (similar to an electric guitar pickup), changing the magnetic flux linking two coils.

This is most likely a secondary evolved characteristic, which means there is not necessarily a connection between the teeth and the original dermal scales. The old placoderms did not have teeth at all, but had sharp bony plates in their mouth. Thus, it is unknown whether the dermal or oral teeth evolved first. It has even been suggested that the original bony plates of all vertebrates are now gone and that the present scales are just modified teeth, even if both the teeth and body armor had a common origin a long time ago.

1957 Viceroy ad Brown & Williamson made various poster and magazine advertisements to promote the Viceroy brand. Various TV ads were also made to promote the brand from the 1950s to the 1970s. One of the most notable Viceroy advertisements, were the ones that advertised that, because Viceroy cigarettes were filter-tipped, less tar would manifest on and between the teeth, and would thus be a "healthier" alternative to other brands. A slogan used in the 1940s ads at the time was "As your dentist, I would recommend Viceroys".

The lower back teeth were close together, and the space between the teeth increased from front to back, suggesting they were used for shearing, unlike the suction-feeding modern-day sperm whales which lack teeth in their upper jaws. The front teeth were more worn on the sides, whereas the bottom teeth were more worn along the middle. It had 12 teeth in the upper jaw and 13 teeth in the bottom jaw, and like other raptorials, it had tooth enamel. The premaxillae bore three teeth, and the maxillae had nine teeth.

The odours are produced mainly due to the breakdown of proteins into individual amino acids, followed by the further breakdown of certain amino acids to produce detectable foul gases. Volatile sulfur compounds are associated with oral malodour levels, and usually decrease following successful treatment. Other parts of the mouth may also contribute to the overall odour, but are not as common as the back of the tongue. These locations are, in order of descending prevalence, inter-dental and sub-gingival niches, faulty dental work, food-impaction areas in between the teeth, abscesses, and unclean dentures.

Similarly, the strongest biting muscle in Ambulocetus seems to have been the temporalis muscle involved in biting down. Like other cetaceans, there are embrasure pits (a depression between the teeth), preserving the tooth positions for the fourth premolar, the first molar, and the third molar. Unlike later archaeoecetes, the roots of the molars do not extend to the cheek bones, and the third molar is not as nosewards as in remingtonocetids. The coronoid process of the mandible (where the lower jaw connects with the skull) in Ambulocetus is steep.

The roots of the upper teeth are anchored into a bone called the maxilla, more commonly known as the hard palate, at ridges called the alveolar process. The roots of the lower teeth are anchored into a bone called the mandible, more commonly known as the jaw, at their respective alveolar processes. The surface of the oral cavity between the teeth and the inner side of the lips are called the oral vestibule. Surrounding the oral cavity, there are many different muscles that facilitate chewing, opening the mouth, and swallowing.

527–528 TE0n modes should not, in theory, be excited in the waffle-iron filter because of its vertical symmetry about the centre- line. However, in practice they can be caused by poorly mating waveguide flanges or misaligned teeth. These spurious modes can be suppressed by fitting thin wires across the width of the filter in the space between the teeth on the vertical centre-line of the waveguide. This can be a better solution than over-engineering the components to high precision and results in a more robust design.

The thin cases are half as thick and can generally only hold one disc as a result, but there are newer slim cases that have central disc holding teeth on both sides. The teeth are made in such a way that when the case is closed, they go between the gaps in between the teeth on the other side. A standard DVD case is a single-piece plastic case with two creases, which folds around and snaps closed. It measures 135 mm × 190 mm × 14 mm (5.3 in × 7.48 in × 0.55 in).

Standard construction elements such as large Regelbau bunkers, smaller concrete "pillboxes", and "dragon's teeth" anti-tank obstacles were built as part of each construction phase, sometimes by the thousands. Frequently vertical steel rods would be interspersed between the teeth. This standardisation was the most effective use of scarce raw materials, transport and workers, but proved an ineffective tank barrier as US bulldozers simply pushed dirt bridges over these devices. "Dragon's teeth" tank traps were also known as Höcker in German ("humps" or "pimples" in English) because of their shape.

Breathing apparatus must allow the diver to breathe with minimum added work of breathing, and minimise additional dead space. It should be comfortable to wear, and not cause stress injury or allergic reactions to component materials. It must be reliable and should not require constant attention or adjustment during a dive, and if possible performance should degrade gradually in the event of malfunctions, allowing time for corrective action to be taken with minimum risk. Holding the scuba mouthpiece between the teeth can case jaw fatigue on a long dive.

Gear meters differ from oval gear meters in that the measurement chambers are made up of the gaps between the teeth of the gears. These openings divide up the fluid stream and as the gears rotate away from the inlet port, the meter's inner wall closes off the chamber to hold the fixed amount of fluid. The outlet port is located in the area where the gears are coming back together. The fluid is forced out of the meter as the gear teeth mesh and reduce the available pockets to nearly zero volume.

However, brushing in the morning and at night is mandatory as well as flossing and using an anti- bacterial mouthwash. Individuals who suffer from diabetes are recommended to use toothpaste that contains fluoride as this has proved to be the most efficient in fighting oral infections and tooth decay. Flossing must be done at least once a day, as well because it is helpful in preventing oral problems by removing the plaque between the teeth, which is not removed when brushing. Diabetic patients must get professional dental cleanings every six months.

Some will pour it on the saucer and slurp it with abandon pleasure. The idea is to get to the last slurp or sip when it is sweetest and in this way encouraging refill. It somewhat reflects the Malay pantun proverb, 'berakit-rakit ke hulu/berenang- renang ke tepian/ bersakit-sakit dahulu/bersenang-senang kemudian', meaning there is a satisfying end to a difficult beginning. Not to be mistaken with the way the Russian drink their tea, by holding the rock sugar between the teeth and sip the tea.

A. eonegundo has compound leaves divided into at least three leaflets, with the leaflets pinnately veined and ranging up to in length. The leaflets have small petiolules and asymmetric bases flaring out on the basal side while remaining narrow on the apical side. Each lateral leaflet has 7 secondary veins that fork near the leaf margin with the inner branch curving upwards to join the next secondary vein up, while the outer fork extends to the leaf margin. The outer forks brace the sinuses between the teeth on the blade margins.

Calculus can form both along the gumline, where it is referred to as supragingival ("above the gum"), and within the narrow sulcus that exists between the teeth and the gingiva, where it is referred to as subgingival ("below the gum"). Calculus formation is associated with a number of clinical manifestations, including bad breath, receding gums and chronically inflamed gingiva. Brushing and flossing can remove plaque from which calculus forms; however, once formed, calculus is too hard (firmly attached) to be removed with a toothbrush. Calculus buildup can be removed with ultrasonic tools or dental hand instruments (such as a periodontal scaler).

Later studies included the Russian Kileskus and the Chinese Sinotyrannus in the family. Recently, Proceratosauridae has been found to include Proceratosaurus, Guanlong, Kileskus, Sinotyrannus, and the genera Stokesosaurus, Juratyrant, and Dilong previously recognized as non-proceratosaurid tyrannosauroids. In their re- evaluation of Proceratosaurus, Rauhut et al. stated that tooth taxa from the Late Jurassic and Early Cretaceous previously assigned to the dromaeosaurid subfamily Velociraptorinae may instead be proceratosaurid in nature, due to the similarity between the teeth of the two groups and the fact that velociraptorines are otherwise unknown from the fossil record until the Late Cretaceous.

Midline diastema (spacing in upper teeth) is a common occurrence in the population. An arbitrary number for the spacing between the teeth to consider as midline diastema is a width of 0.5 from a proximal surface of a teeth to the proximal surface of adjacent teeth. Midline diastema usually occur in the upper teeth compared to lower. The cause of this spacing includes but not limited to microdontia, labial frenulum, peg-shaped lateral incisors, mesiodens, cysts in midlene region, tongue trusting, finger sucking, dental malformations, maxillary incisor proclination, genetics, imperfect joining of interdental septum, dental skeletal discrepancies.

Eventually, later studies would begin to show that much of the sharks within the genus and two species are distinct from each other, discarding the genus Oxyrhina altogether and creating another issue on what new taxa the sharks should be placed in. As of now, the genus is still uncertain and debated. Shortly after the discarding of the genus Oxyrhina, a review by Holec et al. (1995) placed the species hastalis and xiphodon as a species of mako under the genus Isurus, citing the similarities between the teeth of the two and that of modern mako sharks.

Variable-ratio steering is a system that uses different ratios on the rack in a rack and pinion steering system. At the center of the rack, the space between the teeth are smaller and the space becomes larger as the pinion moves down the rack. In the middle of the rack there is a higher ratio and the ratio becomes lower as the steering wheel is turned towards lock. That makes the steering less sensitive when the steering wheel is close to its center position and makes it harder for the driver to over steer at high speeds.

In lemuriform primates, the toothcomb may also play a secondary role in olfaction, which may account for the size reduction of the poorly studied upper incisors. The toothcomb may provide pressure to stimulate glandular secretions which are then spread through the fur. Furthermore, the size reduction of the upper incisors may create a gap between the teeth (interincisal diastema) that connects the philtrum (a cleft in the middle of the wet nose, or rhinarium) to the vomeronasal organ in the roof of the mouth. This would allow pheromones to be more easily transferred to the vomeronasal organ.

The leaves of A. lincolnense are divided into three leaflets, with the lateral leaflets pinnately veined and ranging between in length. The leaflet blades rest against the primary vein of the leaf, lacking petiolules, and have an asymmetric base flaring out on the basal side while remaining narrow on the apical side. Each lateral leaflet has between 5 and 7 secondary veins that alternate between forking near the vein tip before reaching the blade margin, and curving upwards near the tip to join the next secondary vein up. The forking secondary veins brace the sinuses between the teeth on the blade margins.

It may have consisted of connective tissue and skin, rather than muscle fibers, which meant that the tongue was used to move food that had accumulated between the teeth and the cheek, back to the tongue side of the cheek so that it could be further broken down by the teeth. The ornithischian cheek is absent or only weakly developed in Lesothosaurus, which supports its placement as a sister group to Genasauria. In Genasauria, the mandibular symphysis is shaped like a spout and forms at an acute angle. The mandibular symphysis is the point of fusion between the two lateral dentary bones.

While there is tentative benefit from the use of a tongue cleaner it is insufficient to draw clear conclusions with respect to bad breath. A 2006 Cochrane review found tentative evidence of decreased levels of odor molecules. Some studies have shown that it is the bacteria on the tongue which often produce malodorous compounds and fatty acids that may account for 80% to 85% of all cases of bad breath. The remaining 15% to 20% of cases originate in the stomach, from the tonsils, from decaying food stuck between the teeth, gum disease, dental caries (cavities or tooth decay) or plaque accumulated on the teeth.

Wack-O-Wax logo A pair of Wack-O-Wax lips Wax Lips are the common name of a candy product made of colored and flavored food-grade paraffin wax, molded to resemble a pair of oversized red lips. The lips have a bite plate in the back; when the plate is held between the teeth, the wax lips cover the wearer's own lips, to comic effect. Invented by the American Candy Company in the early 20th century, they became a popular novelty in the United States for many decades, especially during the Halloween season. Their popularity among children can be attributed mainly to the comedy of wearing the lips.

Abnormal swallowing patterns push the upper teeth forward and away from the upper alveolar processes and cause open bites. In children, tongue thrusting is common due to immature oral behavior, narrow dental arch, prolonged upper respiratory tract infections, spaces between the teeth (diastema), muscle weakness, malocclusion, abnormal sucking habits, and open mouth posture due to structural abnormalities of genetic origin. Large tonsils and adenoids also contribute to tongue thrust swallowing. From the dental perspective, teeth move in relation to the balance of the soft tissue; the normal relationship of teeth lies in occlusion; and any deviation from the normal occlusion can lead to dental distress.

For gripping tree trunks and large branches, they have large hands and feet with extended pads on the digits, as well as claw-like nails. They have a long tongue which assists obtaining the gum and nectar, as well as a long caecum, which helps digest gums. Their procumbent (forward-facing) lemuriform toothcomb (formed by the lower incisors and canines) is long and more compressed, with significantly reduced interdental spaces to minimize the accumulation of gum between the teeth. The genus is distinguished from other cheirogaleids by the toothrows on its maxilla (upper jaw), which are parallel and do not converge towards the front of the mouth.

Rodrigues & Kellner established two autapomorphies of Camposipterus nasutus. At the front of the jaw edge there is a density of three teeth per , at the rear a density of 2.5 teeth. The snout tip is flat, in front view wider than tall. There is a unique combination of traits: the upper profile of the snout is straight or lightly curved; the midline ridge on the palate is extended forwards until the level of the rear margins of the second tooth pair; to the rear the distance between the teeth gradually increases; the second and third tooth pairs are obliquely pointed sideways; the front of the snout is slightly expanded.

Extrapolating from this, Haas suggested that ankylosaurs ate relatively soft non-abrasive vegetation. Later research on Euoplocephalus indicates that forward and sideways jaw movement was possible in these animals, the skull being able to withstand considerable forces. A 2016 study of the dental occlusion (contact between the teeth) of ankylosaur specimens found that the ability for backwards (palinal) jaw movement evolved independently in different ankylosaur lineages, including Late Cretaceous North American ankylosaurids like Ankylosaurus and Euoplocephalus. A specimen of the ankylosaur Pinacosaurus preserves large paraglossalia (triangular bones or cartilages located in the tongue) that show signs of muscular stress, and it is thought this was a common feature of ankylosaurs.

T. socranskii is found in the space between the teeth and gums of patients with the varying forms of periodontitis. Of the samples taken from across sampling sites of the gum line, T. socranskii is found to be one of the most abundant of its genus. Studies on the human oral microbiome show that Gram-negative organisms including genera Treponema, Prevotella, Selenomonas, Tannerella, Haemophilus, and Catonella are not only present in samples from those with periodontitis, but they are actually selected for and have a much higher abundance than healthy samples. After treatment of periodontitis, there is a shift in the microbial community away from the Gram-negative organisms listed above, and selection for Gram-positive organisms.

It has traditionally been considered less problematic to eat dairy products before meat, on the assumption that dairy products leave neither fatty residue in the throat, nor fragments between the teeth. Many 20th century Orthodox rabbis say that washing the mouth out between eating dairy and meat is sufficient. Some argue that there should also be recitation of a closing blessing before the meat is eaten,Solomon Mordechai Schwadron, Maharsham 3:126Tzvi Hirsch Spira, Darhei Teshuva 89:14 and others view this as unnecessary.Abraham Gombiner, Magen Abraham 494:6 Ashkenazi Jews following kabbalistic traditions, based on the Zohar, additionally ensure that about half an hour passes after consuming dairy produce before eating meat.

Loss of bone due to periodontal disease Periodontitis is an infection of the gums which leads to bone destruction around the teeth in the jaw. Periodontitis occurs after gingivitis has been established, but not all individuals who have gingivitis will get periodontitis. Plaque accumulation is vital in the progression of periodontitis as the bacteria in plaque release enzymes which attack the bone and cause it to break down, and at the same time osteoclasts in the bone break down the bone as a way to prevent further infection. This can be treated with strict oral hygiene such as tooth brushing and cleaning in between the teeth as well as surgical debridement completed by a dental professional.

On 10 December 1830, scientist Michael Faraday wrote a paper for the Journal of the Royal Institution of Great Britain, entitled On a Peculiar Class of Optical Deceptions. Two instances of rotating wheels that appeared to stand still had been pointed out to him and he had read about the somewhat similar palisade illusion in Roget's article. Faraday started experimenting with rotations of toothed cardboard wheels. Several effects had already been described by Plateau, but Faraday also simplified the experiment by looking at a mirror through the spaces between the teeth in the circumference of the cardboard disc. On 21 January 1831, Faraday presented the paper at the Royal Institution, with some new experiments.

The matching of the cusps allowed the teeth to occlude more precisely than in earlier cynodonts. It would grind its food between the teeth in somewhat the same way as a modern rodent, though unlike rodents tritylodontids had a palinal jaw stroke (front-to-back), instead of a propalinal one (back-to-front). The teeth were well suited for shredding plant matter; however, there is evidence that some tritylodontids had more omnivorous diets, much in the same vein as modern mammals with "herbivore dentitions" like modern rats. Like mammaliaformes, tritylodontids have epipubic bones, a possible synapomorphy between both clades, and this suggests they may also have laid eggs, or produced undeveloped fetus-like young like modern monotremes and marsupials.

According to the Encyclopedia of Clothing and Fashion, "The G-string, or thong, [is] a panty front with a half- to one-inch strip of fabric at the back that sits between the buttocks",Steele, Valerie (2005) Encyclopedia of Clothing and Fashion. New York: Charles Scribner's Sons ; p. 121 and Knickers: a Brief History says: "Minor tweaks to the cut earned these skimpy panties different titles—from the thong, which has a one-inch strip of fabric down the back, to a G-string, which, as the name equivalent of Spanish suggests (hilo dental), is more like a string of fabric akin between the teeth."Tomczak, Sarah & Pask, Rachel (2004) Knickers: a Brief History.

The interdental papilla, also known as the interdental gingiva, is the part of the gums (gingiva) that exists coronal to the free gingival margin on the buccal and lingual surfaces of the teeth. The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the anterior teeth and a blunted shape buccolingually for the posterior teeth.Illustrated Dental Embryology, Histology, and Anatomy, Bath-Balogh, Elsevier, 2011, page 123 A missing papilla is often visible as a small triangular gap between adjacent teeth. The relationship of interdental bone to the interproximal contact point between adjacent teeth is a determining factor in whether the interdental papilla will be present.

This effectively produces an evolute which can be termed the resultant axis of mandibular rotation, which lies in the vicinity of the mandibular foramen, allowing for a low-tension environment for the vasculature and innervation of the mandible. The necessity of translation to produce further opening past that which can be accomplished with sole rotation of the condyle can be demonstrated by placing a resistant fist against the chin and trying to open the mouth more than 20 or so mm. The resting position of the temporomandibular joint is not with the teeth biting together. Instead, the muscular balance and proprioceptive feedback allow a physiologic rest for the mandible, an interocclusal clearance or freeway space, which is 2 to 4 mm between the teeth.

Intraorally, if the fracture occurs in the tooth bearing area, a step may seen between the teeth on either side of the fracture or a space can be seen (often mistaken for a lost tooth) and bleeding from the gingiva in the area. There can be an open bite where the lower teeth, no longer meet the upper teeth. In the case of a unilateral condylar fracture the back teeth on the side of the fracture will meet and the open bite will get progressively greater towards the other side of the mouth. Sometimes bruising will develop in the floor of the mouth (sublingual eccymosis) and the fracture can be moved by moving either side of the fracture segment up and down.

Some have become more widespread and continue to be popular today. One common game is apple bobbing or dunking (which may be called "dooking" in Scotland)"Apple dookers make record attempt" , BBC News, 2 October 2008 in which apples float in a tub or a large basin of water and the participants must use only their teeth to remove an apple from the basin. A variant of dunking involves kneeling on a chair, holding a fork between the teeth and trying to drive the fork into an apple. Another common game involves hanging up treacle or syrup-coated scones by strings; these must be eaten without using hands while they remain attached to the string, an activity that inevitably leads to a sticky face.

Along the way he had discovered a type of abstract animation discs by counter-rotating lines or slits in discs in 1828 (in 1829 he further developed aspects of this principle into a first prototype of what would become the anorthoscope). In 1830, Michael Faraday had published a paper about several illusions that occur in rotating cogwheels and toothed discs, coincidentally repeating some of Plateau's findings. A note added to the paper discussed a disc that in addition to the teeth in the circumference had a different amount of holes regularly spaced across a circular zone closer to the center of the disc. When looking into a mirror through the spaces in between the teeth, the holes appeared to be moving across the disc (or vice versa if looking through the holes).

In 1966, having been unable to secure the lease of the Whitehall Theatre, Rix took his company on tour in Chase Me, Comrade and Bang, Bang Beirut (later retitled Stand By Your Bedouin), by Cooney and Hilton.Smith, p. 96 Later productions by the Rix company at the Garrick Theatre and elsewhere included Uproar in the House (1967), by Anthony Marriott and Alistair Foot; Let Sleeping Wives Lie (also 1967) by Harold Brooke and Kay Bannerman; She's Done It Again (1969), by Michael Pertwee; Don't Just Lie There, Say Something (Pertwee, 1971); and A Bit Between the Teeth (Pertwee, 1974). According to Leslie Smith in a study of modern British farce, although some of the Rix productions after Chase Me, Comrade achieved substantial success, none of them had the conspicuously long runs of the five Whitehall farces.

Unless the ends of one of the pallets is long enough to sit into the gap between the teeth of the escape wheel then the wheel will run free as soon as the clock is wound. The same problem can arise if the hinges for the stops get dirty and stick in a raised position. Unlike most other escapements of its time, the grasshopper pushes the pendulum back and forth throughout its cycle; it is never allowed to swing freely. Around the same time as Harrison invented the grasshopper, George Graham introduced the deadbeat escapement,Andrewes, W.J.H., Clocks and Watches: The leap to precision in invented by Richard Towneley in 1675, which allowed the pendulum to be damped by friction during most of its cycle, impulsed rapidly and subject to an unpredictable interruption of impulse as the escape wheel advanced.

Despite their very early occurrence in the fossil record, coelophysoids have a number of derived features that separate them from primitive (basal) theropods. Among the most prominent of these derived features (apomorphies) is the way the upper jaw bones are connected (the premaxilla-maxilla articulation), which is flexible with a deep gap between the teeth in the two bones. A major source of disagreement among theropod experts is whether or not coelophysoids shared a more recent common ancestor with Ceratosauria (sensu stricto) than the ceratosaurs did with other theropods. Most recent analyses indicate the latter, that Coelophysoidea does not form a natural group with the ceratosaurians. Similarly, while Dilophosaurus and similar theropods have traditionally been classified as coelophysoids, several studies published in the late 2000s suggested that they may actually be more closely related to the tetanurans.

Rix who had never enjoyed touring now hated the endless nights away from home and was delighted when the play was turned first into a television series for HTV, Men of Affairs (with Warren Mitchell as the minister) and then into a film (starring himself, Leslie Phillips and Joanna Lumley). After that, during the Three-Day Week in 1973–74, came a relatively unsuccessful pantomime season in Robinson Crusoe at the New Theatre, Cardiff. Rix was by now becoming tired of going on stage night after night and sensing he had reached the peak of his success began to consider retiring from the stage. There were two more farces to come however, A Bit Between the Teeth (with Jimmy Logan and Terence Alexander) at the Cambridge Theatre and then, back at the Whitehall, Fringe Benefits (with Terence Alexander and Jane Downs).

As a consequence, his work often receives mixed reviews from critics, some of whom have noted a tendency toward grandiosity and obviousness in some of his work. Yet it is this very ambitiousness, his striving toward meaning, and attempts to deal with the big themes of human life, that also make his work so clearly appreciated by other critics, his audiences and collectors. His early work established his fascination with issues that continue to inform his work today. In particular, Viola's obsession with capturing the essence of emotion through recording of its extreme display began at least as early as his 1976 work, The Space Between the Teeth, a video of himself screaming, and continues to this day with such works as the 45-second Silent Mountain (2001), which shows two actors in states of anguish.

A maxilla (almost complete, with a number of teeth), a molar, a fibula, and four fragments of a cranium belonging to two humans were found between 2000 and 2003, in what appeared to be a layer from the Mousterian. All fragments except for the molar were from an adult, who died at between 35 and 45 years old; the molar was from a child of around 2.5 years old. The maxilla showed periodontal disease and heavy dental wear, which must have caused considerable pain; there was a significant gap (8.05 mm for the canine) between the teeth and the alveolar bone. The person attempted to alleviate the discomfort with a toothpick, as evidenced by two grooves on the distal surface of two of the remaining teeth: "the habit of using a tool to pick the teeth may be considered early evidence of medical treatment to alleviate sore gums".

In 1981, Byrne partnered with choreographer Twyla Tharp, scoring music he wrote that appeared on his album The Catherine Wheel for a ballet with the same name, prominently featuring unusual rhythms and lyrics. Productions of The Catherine Wheel appeared on Broadway that same year. In Spite of Wishing and Wanting is a soundscape David Byrne produced for the Belgian choreographer Wim Vandekeybus's dance company Ultima Vez. Byrne wrote, directed, and starred in True Stories, a musical collage of discordant Americana released in 1986, as well as producing most of the film's music. Byrne also directed the documentary Île Aiye and the concert film of his 1992 Latin-tinged tour titled Between the Teeth. He was chiefly responsible for the stage design and choreography of Stop Making Sense in 1984. Byrne was impressed by the experimental theatre that he saw in New York City in the 1970s. He collaborated with several of its best-known representatives.

One of the two identity discs issued by the South African Navy during World War II with rank, surname, initials, force number and religious affiliation British WWII RAF Dog tag of the Jewish soldier Astman, identification number 775923. There is a recurring myth about the notch situated in one end of the dog tags issued to United States Army personnel during World War II, and up until the Vietnam War era. It was rumored that the notch's purpose was that, if a soldier found one of his comrades on the battlefield, he could take one tag to the commanding officer and stick the other between the teeth of the soldier to ensure that the tag would remain with the body and be identified. In reality, the notch was used with the Model 70 Addressograph Hand Identification Imprinting Machine (a pistol-type imprinter used primarily by the Medical Department during World War II).

For this reason, it is necessary to shut off the electron beam (corresponding to a video signal of zero luminance) during the time it takes to reorient the beam from the end of one line to the beginning of the next (horizontal retrace) and from the bottom of the screen to the top (vertical retrace or vertical blanking interval). The horizontal retrace is accounted for in the time allotted to each scan line, but the vertical retrace is accounted for as phantom lines which are never displayed but which are included in the number of lines per frame defined for each video system. Since the electron beam must be turned off in any case, the result is gaps in the television signal, which can be used to transmit other information, such as test signals or color identification signals. The temporal gaps translate into a comb-like frequency spectrum for the signal, where the teeth are spaced at line frequency and concentrate most of the energy; the space between the teeth can be used to insert a color subcarrier.

A diver in a pool wearing an AGA full face mask A diver wearing an Ocean Reef full face mask Head protection helmet for use with Ocean Reef full face diving mask A full-face diving mask is a type of diving mask that seals the whole of the diver's face from the water and contains a mouthpiece, demand valve or constant flow gas supply that provides the diver with breathing gas. The full face mask has several functions: it lets the diver see clearly underwater, it provides the diver's face with some protection from cold and polluted water and from stings, such as from jellyfish or coral. It increases breathing security and provides a space for equipment that lets the diver communicate with the surface support team. Full-face masks can be more secure than breathing from an independent mouthpiece; if the diver becomes unconscious or suffers an oxygen toxicity convulsion, the diver can continue to breathe from the mask, unlike a scuba mouthpiece which is normally gripped between the teeth.

The Bendix system places the starter drive pinion on a helical drive spring. When the starter motor begins turning, the inertia of the drive pinion assembly causes it to wind the spring forcing the length of the spring to change, and allowing the pinion to engage with the ring gear. When the engine starts, backdrive from the ring gear causes the drive pinion to exceed the rotative speed of the starter, at which point the drive pinion is forced back and out of mesh with the ring gear. The main drawback to the Bendix drive is that it relies on a certain amount of "clash" between the teeth of the pinion and the ring gears before they slip into place and mate completely; the teeth of the pinion are already spinning when they come into contact with the static ring gear, and unless they happen to align perfectly at the moment they engage, the pinion teeth will strike the teeth of the ring gear side-to-side rather than face-to-face, and continue to rotate until both align.

Music, dance and singing are part of many a Kanak ceremonial function such as initiation, courting and mourning. Conch shells are blown by an appointed person to represent a clan chief's arrival or the voice of an ancestor. Rhythm instruments used include Bwanjep, used during ceremonies by a group of men; Jew's harp, (wadohnu in the Nengone language where it originated) made of dried piece of coconut palm leaf held between the teeth and an attached segment of soft nerve leaf; coconut-leaf whizzer, a piece of coconut leaf attached to a string and twirled that produces a noise like a humming bee; oboe, made of hollow grass stems or bamboo; end-blown flute, made of 50 cm long hollowed pawpaw leaf stem; bamboo stamping tubes that are struck vertically against the ground and played at major events; percussion instruments (hitting sticks, palm sheaths); rattles that are worn on the legs made of coconut leaves, shells and certain fruits. Kanak groups such as Bethela first made the recordings on cassette around 1975 or 1976.
