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.
The prevalence, possible etiological factors and management of hypodontia was briefly reviewed. A report of a case of hypodontia affecting the primary and permanent lower incisors was described.
