Multiple Talon Cusps and Dens Invaginatus Associated with Other Dental Anomalies — an Unusual Report

Talon cusp is a dental anomaly that occurs as an accessory cusp like structure from the cingulum of maxillary or mandibular anterior teeth. Dens invaginatus is a developmental variation which arises as a result of an invagination on the surface of a tooth crown before calcification has occurred. An unusual case of multiple talon cusps affecting the maxillary central incisors and the canines bilaterally together with other dental abnormalities viz dens invaginatus affecting the maxillary lateral incisors, microdontia, short roots, reduced alveolar bone height, dilaceration of the described posterior teeth, anterior open bite and bilateral posterior cross bite in a 35 year old male. The presence of these dental anomalies in a single patient is very rare and this is perhaps the first case report of this nature. None of these anomalies alone are particularly uncommon but they have not previously been reported together. The occurrence of these anomalies is probably incidental as the conditions are aetiologically unrelated and no developmental syndrome was identified.
