Talon cusp in fused teeth: A rare concomitant occurrence

Abstract

Talon cusp and fusion of teeth are two separate developmental dental anomalies affecting both primary and permanent dentitions. While the former is more common in permanent maxillary incisors, the latter occurs more commonly in deciduous maxillary anterior teeth. This paper describes a rare case of talon cusp in fused teeth affecting the permanent mandibular incisors. A note on the etiopathogenesis of these two anomalies and a possible hypothesis on their concurrent occurrence are mentioned. The importance of awareness and understanding of these lesions and the prophylactic measures to prevent complications is also discussed.
