DENTITION
The type, number, and arrangement of teeth in the dental arch. See: illustration; teeth for illus.

diphyodont dentition

Two sets of teeth (i.e., primary and permanent, as in many mammals and humans).

heterodont dentition

A set of teeth of various shapes that may serve different functions (e.g., incisors, canines, and molars).

impaired dentition

Disruption in tooth development/eruption patterns or structural integrity of individual teeth.

mixed dentition

A set of both primary and permanent teeth, as in children between 6 and 13 years of age.

monophyodont dentition

A single set of teeth.

permanent dentition

The 32 permanent teeth, which begin to erupt at about 6 years of age in people. These are completed by the 16th year with the exception of third molars, which appear between the 18th and 25th years. The incisors are followed by the bicuspids (premolars) and the canines; then the second molars are followed by the third molars. In some individuals the third molars, although present beneath the gingiva, do not erupt. The appearance of the first molars is highly variable, but in some instances they may be the first permanent teeth to appear.
Synonym: dens permanens See: teeth

polyphyodont dentition

Several successive sets of teeth developing during a lifetime.

primary dentition

The 20 primary or deciduous teeth in children. In general, the order of eruption is two lower central incisors, 6 to 8 months; two upper central incisors, 5 to 7 months; two lower lateral incisors, 8 to 11 months; two upper lateral incisors, 7 to 10 months; four canines (cuspids), lower and upper, 16 to 20 months; four first molars, lower and upper, 10 to 16 months; four second molars, upper and lower, 20 to 30 months.

dentition

dentition, mixed,

This period usually begins with the eruption of the first permanent molars and ends with the exfoliation of the last primary tooth. Also called the transitional dentition. See also ugly duckling stage.
dentition, permanent (secondary dentition, permanent teeth),
n the 32 teeth of adulthood that either replace or are added to with the shedding (exfoliation) of the primary teeth.
dentition, primary,
n the 12 teeth present that erupt first and are usually replaced by the permanent teeth. This term is currently preferred over
deciduous.
dentition, prognosis of,
n an evaluation by the dental professional of the prospect of recovery from dental disease, combined with a forecast of the probability of maintaining the dentition and its associated structures in function and health.
