teeth (redirected from opposing teeth)

teeth (tth)

n.

Plural of tooth.

teeth,

n See tooth.

teeth, hypermobile,

n the propensity of teeth to abnormally move or shift positions within the alveolar bone. This condition can occur as a result of inflammation, metabolic abnormalities, or traumatic injury.

teeth, milk,

n See teeth, primary.

teeth, opposing,

n teeth that are opposite each other, one in the maxilla and one in the mandible, that ideally come into occlusal contact with each other.

teeth, short,

n teeth that are severely worn from erosion or abrasion.

teeth, splayed anterior,

n anterior teeth that have been forced to slope outward, usually as a result of pressure from the tongue.

teeth, tilted,

n teeth that are at such an angle as to cause them to be out of centric contact with opposing teeth during occlusion.

teeth

small, bonelike structures of the jaws for the biting and mastication of food. Plural of tooth. See also dental, tooth.

teeth abscess

see alveolar1 abscess, malar abscess.

accessional teeth

the permanent molars, so called because they have no deciduous predecessors in the dental arch.

anelodont teeth

teeth with a limited period of growth.

anterior teeth

usually taken to include incisors and canines.

teeth attrition

see dental attrition.

baby teeth

see deciduous teeth (below).

brachyodont teeth

a type of dentition as seen in humans and pigs; the teeth have short crowns, well developed roots and a narrow root canal. See also hypsodont, bunodont.

bunodont teeth

see bunodont.

canine teeth

the long, pointed tooth in the interdental space between incisors and cheek teeth; there is one in each jaw on both sides.

carnassial teeth

see carnassial tooth.

teeth cavity

see dental cavity, pulp cavity.

deciduous teeth

the temporary set of teeth that erupt in the young and are shed before or near maturity. They have smaller crowns and root systems and are fewer in number than the permanent teeth that replace them. Called also milk teeth, temporary teeth, baby teeth. Occasionally, particularly in small breeds of dogs, shedding of the deciduous tooth may not occur when the permanent replacement has erupted, necessitating veterinary intervention.

Retained deciduous canine tooth in a dog.

diphyodont teeth

see diphyodont.

displaced molar teeth

see inherited displacement of molar teeth.

ectopic teeth

see dental cyst.

embedded teeth

unerupted.

congenital teeth enamel deficiency

see inherited enamel defect.

teeth eruption time

see Table 19.

teeth excessive wear

occurs in animals on high fluorine intake or on diets low in calcium.

geminous teeth

see gemination.

teeth grinding

1. grinding of the incisors to improve foraging ability. Has been done to sheep with an industrial angle grinder with indifferent results.

2. see bruxism.

heterodont teeth

see heterodont.

homodont teeth

see homodont.

hypsodont teeth

a form of dentition, seen in horses and many ruminants; the crown is high (deep), the root is short.

impacted teeth

one so placed in the jaw that it is unable to erupt or to attain its normal position in occlusion.

incisor teeth

the front teeth used for cropping grass or rending flesh. From two to four in each quadrant, depending on the species, except that they are missing in the upper jaw of ruminants.

inherited molar teeth displacement

see inherited displacement of molar teeth.

lophodont teeth

cheek teeth with ridged occlusal surfaces. See also lophodont.

teeth maleruption

defective eruption; includes delayed eruption and more usually eruption out of its normal position.

milk teeth

see deciduous teeth (above).

molar teeth

the permanent, primary cheek teeth that are not preceded by premolars. They are typically big teeth used for grinding and with ridges on their occlusal surfaces (lophodont) in horses, worn rounded cusps (bunodont) in pigs, or including crescents (selenodont) in cattle, and either cutting edges or flattened areas in carnivores.

monophyodont teeth

see monophyodont.

needle teeth

any small sharp teeth in piglets but principally the canine teeth.

permanent teeth

see permanent dentition.

teeth pigmentation

see tetracycline stain.

pink teeth

caused by staining with porphyrin, or by deficiency of dentine and enamel, a congenital defect.

premature teeth loss

a problem in New Zealand sheep. Characterized by acute then chronic gingivitis, then periodontitis and loss of teeth. Cause unknown.

premolar teeth

cheek teeth present in both generations, found between the molars and canines. The first premolar is exceptional in humans because it erupts late and is never replaced. In domestic species, there are up to three or four deciduous, followed by up to four permanent premolars in both jaws and on both sides.

teeth rasp

see tooth rasp.

retained teeth

deciduous premolars or incisors may be retained even though the permanent teeth have erupted. The deciduous crowns are likely to protrude at odd angles and cause difficult mastication.

secodont teeth

see secodont.

sectorial teeth

a cutting tooth. See carnassial tooth.

selenodont teeth

teeth with crescents in their grinding surfaces, as in the cheek teeth of ruminants.

sharp teeth

the edges of molar teeth in the horse which require frequent rasping because of the injury that they might cause to the oral mucosa.

stained teeth

red-brown in inherited porphyrinuria in cattle, frequent dosing with tetracyclines, heavy staining with brown tartar in ruminants with a rumination and prehension problem, usually due to loss of anterior part of tongue.

supernumerary teeth

teeth in excess of the normal complement, e.g. double row of incisors. Called also polyodontia, heterotopic polydontia.

temporary teeth

see deciduous teeth (above).

wolf teeth

see wolf tooth.
