Microdontia is most commonly seen in which tooth?

• A. Maxillary premolars
• B. Mandibular inferior incisor
• C. Maxillary lateral incisor
• D. Maxillary central incisor

Answer: (C)

Microdontia means a tooth is smaller than normal, and the tooth most commonly affected is the maxillary lateral incisor. This is often seen as a peg-shaped lateral incisor, a classic presentation of true microdontia in the anterior region. The development of the lateral incisor is particularly variable during morphogenesis, and genetic factors frequently play a role, making this tooth more susceptible than others. In contrast, mandibular incisors, maxillary central incisors, and premolars are less commonly involved in true microdontia, so the lateral incisor stands out as the typical site.
