Which teeth are most commonly affected by microdontia?

• A. Canines
• B. Lateral incisors
• C. Molars
• D. Central incisors

Answer: (B)

Microdontia refers to the condition where a tooth or teeth are smaller than the normal size. The lateral incisors are particularly susceptible to this condition, making them the most commonly affected teeth. This is primarily seen in the maxillary lateral incisors, which may present as a peg shape, significantly smaller than adjacent teeth.

Understanding the prevalence of microdontia in certain teeth can aid dental professionals in diagnosing and managing treatment options, especially in young patients. The presence of microdontia, especially in the lateral incisors, can also inform conversations about esthetics and function in dental treatment plans.
