Abstract

Dens evaginatus (DE) is a developmental malformation characterized by the presence of an extra cusp or tubercle. Dens invaginatus (DI) is also a dental anomaly found in tooth where the outer surface folds inward. Although each configuration was a rare developmental dental anomaly, the concurrence of DE and DI in a single tooth is an extremely rare. Those anomaly teeth are clinically significant due to the susceptible to dental caries or the possibility of the pulpal disease such as pulpitis and necrosis pulps without clinical history. Therefore, it is important to prevent further worse complications through the early diagnosis and intervention. Here we report that a clinical case of DE and DI concurrently affecting the mandibular central incisor in a 6-year-old Japanese girl, along with a pertinent review of the literature. Key words Dens evaginatus, Dens invaginatus, Talon cusp.
