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.

The typical clinical features of PLS include palmoplantar hyperkeratosis and generalized aggressive periodontitis accompanied by severe alveolar bone destruction, leading to early loss of both primary and permanent dentitions. The clinical manifestations observed in our patients were hyperkeratosis of the soles, palms and generalized aggressive periodontitis which resulted in loss of the primary and permanent teeth.10 Various etiological factors are associated with the syndrome like immunologic alterations, genetic mutations and the role of bacteria.
