Talon cusp in primary dentition--case report

A case of talon cusp in the primary maxillary left central incisor is reported. This dental anomaly was not associated with any other somatic or dental abnormality. Though pulpal extension into the cusp was detected radiographically, clinical examination after the cusp was ground failed to reveal any pulpal extension. The tooth was badly carious and was restored with a polycarbonate crown.
