When pressure is exerted on a tooth, such as during chewing or biting, the tooth moves slightly in its socket and puts tension on the periodontal ligaments.

Each time one pallet moves away from the escape wheel, releasing a tooth, the wheel turns and a tooth on the other side catches on the other pallet, which is moving toward the wheel.

The fastest wheel turns round each day through 2928 teeth ( chhih ), the slowest one moves by 1 tooth in every 5 days.

The pain, generally dull, often moves from one tooth to another for a period of 4 months to several years.

Bugs ducks into a haystack, and soon comes face to face with a Japanese soldier ; a short, bucked tooth, monkey-footed Japanese man who says his ' Ls ' as ' Rs ' and who might be rapidly stating the names of Japanese cities whenever he moves.

The impulse received by the entrance pallet as the tooth moves over the impulse face is transferred by the lever to the balance wheel via the ruby impulse pin on the roller of the balance wheel.

The lever moves until it rests against the right banking pin ; it is held in this position by the force of the exit tooth against the exit pallet jewel ( called the draw ).

:* Any wolf tooth which moves is likely to be small, a fragment or be a fractured crown.

The Aleuts pierced holes around the rim of their ears with dentalium shells ( tooth shells or tusk shells ), bone, feathers, dried bird wings or skulls and / or amber.

Saddles are typically made of plastic or bone for acoustic guitars, though synthetics and some exotic animal tooth variations ( e. g. fossilized tooth, ivory, etc.

The remains include six human bones: a knucklebone from the right hand, a tooth, part of a cranium, a rib, and an ulna, or forearm bone.

More exotic materials usually only seen on art or ceremonial knives include: Stone, bone, mammoth tooth, mammoth ivory, oosik ( walrus penis bone ), walrus tusk, antler ( often called stag in a knife context ), sheep horn, buffalo horn, teeth, mop ( mother of pearl or " pearl ") etc.

However, it may have been for religious reasons, and would coincide with the development of religious practices thought to have occurred during the Upper Paleolithic .< ref > Nonetheless, it remains possible that Paleolithic societies never practiced cannibalism, and that the damage to recovered human bones was either the result of ritual post-mortem bone cleaning or predation by carnivores such as saber tooth cats, lions and hyenas.

Impaired tooth mobility and tooth loss can be caused by destruction of the supporting bone and by heavy forces being placed on teeth.

* Low intensity pulsed ultrasound is used for therapeutic tooth and bone regeneration.

Thus two tooth cattle are marked on the wither, four tooth on the middle of the back and six tooth on their high bone ( near tail ).

Effects consist of the following: bleeding upon probing, increased gingival exudate, pronounced gingival inflammatory response to plaque levels, associated in some instances with bone loss but without tooth detachment.

There is evidence that Tyrannosaurus did have aggressive head-on encounters with Triceratops, based on partially healed tyrannosaur tooth marks on a Triceratops brow horn and squamosal ; the bitten horn is also broken, with new bone growth after the break.

It turns out that he did not leave Nelson deliberately ; he bit into a chocolate bar, not knowing it had peanuts and had an allergic reaction that gave him neurofibramatosis which impacted his wisdom tooth in the upper left corner with a large bone coming out of the jaw which went into his spine, covering 90 % of his body with large tumors of chronic bronchitis.

Cementum is a specialized bone like substance covering the root of a tooth.

A: tooth B: gingiva C: bone D: periodontal ligaments

The periodontal ligament is a specialized connective tissue that attaches the cementum of a tooth to the alveolar bone.

This tissue covers the root of the tooth within the bone.

The functions of the periodontal ligaments include attachment of the tooth to the bone, support for the tooth, formation and resorption of bone during tooth movement, sensation, and eruption.

An extremely rich source for adult mesenchymal stem cells is the developing tooth bud of the mandibular third molar.

The tooth bud ( sometimes called the tooth germ ) is an aggregation of cells that eventually forms a tooth.

These three types form from a mass of epithelial cells known as the epithelial cuff between the tooth and the mouth.

When tooth destruction occurs at the roots of teeth, the process is referred to as internal resorption, when caused by cells within the pulp, or external resorption, when caused by cells in the periodontal ligament.

This is a result of the virus killing the cells responsible for manufacturing the tooth enamel.

Thus, crosscut saws have sawteeth that are usually shaped, often with a metal file, in such a way that they form a series of tiny knifelike edges. The wood cells ( straws ) are contacted by the knife-edge of the tooth and cut.

Cementum is excreted by cells called cementoblasts within the root of the tooth and is thickest at the root apex.

In the context of tooth eruption, PTHrP is secreted by the cells of the Reduced Enamel Epithelium.

* Dental papilla, cells involved in a developing tooth

The dental pulp is the part in the center of a tooth made up of living connective tissue and cells called odontoblasts.

Ameloblasts are cells, present only during tooth development, that deposit tooth enamel, the hard outermost layer of the tooth that forms the chewing surface.

The adhesion, invasion, and persistence within the oral cells are considered the virulence mechanism of S. mutans to colonize and survive in the oral cavity in the absence of a tooth surface.

Tomes ' processes are a histologic landmark identified on an ameloblast, cells involved in the production of tooth enamel.

These cells enter the pharyngeal pouches and arches where they contribute to the thymus, bones of the middle ear and jaw and the odontoblasts of the tooth primordia.

The tooth bud ( sometimes called the tooth germ ) is an aggregation of cells that eventually forms a tooth.

The growth of cervical loop cells into the deeper tissues forms Hertwig's Epithelial Root Sheath, which determines the root shape of the tooth.

The eyeteeth ( third from the middle on top, counting each front tooth as the first ) beginning to protrude like fangs.

Contrary to the thinking of 30 to 40 years ago, when all malocclusion was blamed on some unfortunate habit, recent studies show that most tooth irregularity has at least its beginning in hereditary predisposition.

When a tyrannosaur would have pulled back on a piece of meat, the force would tend to push the tip of tooth toward the front of the mouth and the anchored root would experience tension on the posterior side and compression from the front.

This would typically incline the tooth to crack formation on the posterior side of the tooth, but the ampullae at the base of the already crack-like serrations would tend to diffuse potential crack-forming forces.

Alligators differ from crocodiles principally in having wider and shorter heads, with more obtuse snouts ; in having the fourth, enlarged tooth of the under jaw received, not into an external notch, but into a pit formed for it within the upper one ; in lacking a jagged fringe which appears on the hind legs and feet of the crocodile ; in having the toes of the hind feet webbed not more than half way to the tips ; and an intolerance to salinity, alligators strongly preferring fresh water, while crocodiles can tolerate salt water due to specialized glands for filtering out salt.

A tooth-gift was a gift given to an infant on the cutting of the first tooth.

He favorably compares a modern tooth suspected of coming from a Bigfoot to the Meganthropus fossil teeth, noting the worn enamel on the occlusal surface.

The jaw joint is generally well above the plane of tooth occlusion, allowing extra room for masseteric attachment on the dentary and causing the rotation of the lower jaw to be translated into straight-ahead crushing force between the teeth of the upper and lower jaws.

When the clutch locked up the driven mechanism coasted and its inertia rotated the disc until a tooth on it engaged a pawl that kept it from reversing.

The Code consists of 282 laws, with scaled punishments, adjusting " an eye for an eye, a tooth for a tooth " ( lex talionis ) as graded depending on social status, of slave versus free man.

" The investigations at Bristol, applying isotope tests on tooth enamel, checked whether she was born and brought up in Wessex and Mercia, as written history has indicated.

In 2005, two students claimed to have found a huge tooth embedded in the body of a deer on the loch shore.

Some have pores underneath ( and are usually called boletes ), others have spines, such as the hedgehog mushroom and other tooth fungi, and so on.

The fixative will restore the " tooth " and more pastel can be applied on top.

Laurin & Klement's first motorcyclette, powered by an engine mounted on the handlebars driving the front wheels, proved dangerous and unreliable — an early incident on it cost Laurin a front tooth.
