Dens invaginatus (DI or dens in dente) and Talons cusp or dens evaginatus are relatively rare developmental anomalies which affect the shape of teeth. DI is a deep surface invagination of the crown or root which is commonly detected on routine radiographic examination. Talon cusp is an additional cusp that projects predominately from the lingual surface of anterior teeth. These anomalies most commonly may be observed in the maxillary lateral tooth. Concurrently, the coexistence of these two anomalies in a single tooth is considered extremely rare. However, still in literature, there are a few reports cases available. This article is a case report of Talons cusp with DI involving maxillary lateral incisors in a 16-year-old patient.
