RAJASHEKHARA, BS et al. Bilateral fusion of primary mandibular lateral incisors and canines: a report of a rare case. Rev. odonto ciênc. (Online) []. 2010, 25, 4, pp. 427-429. ISSN 1980-6523.

PURPOSE: Synodontia or fusion is a developmental anomaly of shape of tooth formed by union of two independently developing primary or secondary teeth. Prevalence of tooth fusion is estimated at 0.5-2.5% in the primary dentition and less in permanent dentition. The bilateral type of fusion in the primary dentition is rare and is about 0.02%. This paper describes a rare case of bilateral fusion of primary mandibular lateral and canine teeth. CASE DESCRIPTION: An 8 year old girl had a complaint of unusually large sized teeth in her mandible. After physical examination and use of periapical radiographs and study models bilateral fused teeth in the mandibular lateral incisor and canine region was diagnosed. CONCLUSION: The bilateral fusion of primary mandibular lateral and canine teeth is a rare condition and should be carefully evaluated to diagnose any associated pathology.
