What teeth are most typically affected by Dens invaginatus?

• A. Mandibular premolars
• B. Maxillary incisors
• C. Maxillary laterals
• D. Mandibular molars

Answer: (C)

Dens invaginatus, also known as dens in dente, is a developmental anomaly that typically occurs when there is a folding of the enamel and dentin into the pulp chamber of a tooth. This condition is most commonly observed in maxillary incisors, particularly maxillary lateral incisors. The anatomical structure of maxillary incisors makes them more susceptible to this condition due to their development; they have a more pronounced and deep palatal invagination, which is conducive to such an anomaly.

This condition can lead to complications such as pulp necrosis or periapical pathologies, primarily because the deep invagination can trap bacteria and impede adequate cleaning during routine dental care. While other teeth can be affected by dens invaginatus, the prevalence in maxillary incisors, especially laterals, is significant enough that they are considered the typical teeth involved in this condition.
