Labial talon cusp on maxillary central incisors: a rare developmental dental anomaly.
Labial talon cusp, or dens evaginatus is a very rare dental anomaly of unclear etiology and significance. It can occur as an isolated finding or be associated with other dental anomalies or some syndromes. The present report describes two Caucasian males with labial talon cusp on maxillary permanent left central incisors. In both cases accessory cusp caused plaque accumulation and marginal gingivitis. One case displayed affected tooth to be in cross bite position causing occlusal trauma. No other dental anomalies in either case, neither association with some syndromes were noted. This rare anomaly requires careful dental and physical examination of the affected patient since its finding can be of clinical and genetic significance.
