Talon cusp and dens invaginatus are developmental anomalies of the human dentition. They not only affect the esthetic appearance of teeth but also may create difficulties during dental treatment and lead to a number of dental problems. Both anomalies are observed most commonly in the lateral maxillary incisor and rarely in the mandibular dentition. The simultaneous occurrence of talon cusp and dens invaginatus in a single tooth is very rare in the mandibular dentition and, to the authors' knowledge, has not yet been reported in a mandibular lateral incisor. This article presents a rare case of dens invaginatus and talon cusp occurring concurrently in a mandibular lateral incisor. Three-dimensional imaging modality was used to describe the complex internal anatomy.
