b) Deciduous and permanent dentition
c) Mixed and specialized dentition
d) Incisor and molar dentition

Answer 1

Individuals have deciduous and permanent dentition over their lifetime. Deciduous teeth, or baby teeth, first appear at about 6 months and are later replaced by permanent teeth during childhood.

Step-by-step explanation:

The types of dentition individuals have in their lifetime are: b) Deciduous and permanent dentition. During a human's lifetime, they have two sets of teeth, or dentitions. The first set, known as the deciduous or baby teeth, begins to emerge around 6 months of age. This set typically consists of 20 teeth. As a person ages, these are replaced by a second set of permanent teeth, which usually totals 32, including incisors for cutting, canines for tearing, premolars (or bicuspids) for crushing, and molars for grinding food. Deciduous teeth are normally shed and replaced by permanent teeth between approximately age 6 and 12.
