What teeth are most commonly affected by dens evaginatus?

• A. Incisors
• B. Canines
• C. Premolars
• D. Molar teeth

Answer: (C)

Dens evaginatus is a developmental anomaly that primarily affects the premolar teeth. This condition is characterized by the presence of an additional cusp, or an enamel protuberance, typically arising from the occlusal surface of a premolar. The anomaly may present a risk for wear, fracture, or pulp exposure due to the increased functional demand on these teeth during chewing.

Premolars are particularly susceptible to this condition due to their anatomical and functional roles, differing from incisors and canines, which primarily engage in cutting and tearing. Molar teeth can occasionally exhibit characteristics associated with dens evaginatus but are not the primary teeth involved.

Understanding the specific prevalence of dens evaginatus in premolars is crucial for pediatric dentists, as it aids in diagnosis and treatment planning for young patients who may present with these anatomical challenges.
