An unusual case of double teeth with facial and lingual talon cusps

Double teeth and talon cusps are rare developmental dental anomalies affecting both primary and permanent dentitions. Talon cusps normally occur on the palatal surface of permanent maxillary incisors, although double teeth are more common in the primary anterior dentition. This paper describes a rare case of fusion of the mandibular permanent incisors with labial and lingual talon cusps. An understanding of these dental anomalies and their associated problems are important to provide prophylactic measures, thereby preventing or minimizing possible complications.
