A rare case of bilateral fusion of maxillary premolar and molar - a case report.

Abstract

Fusion is a developmental anomaly characterized by the union of two adjacent teeth producing a single tooth. These teeth may be fused by enamel, dentin, or both. The prevalence of fusion in permanent dentition is approximately 0.2% whereas cases of bilateral fusion are less frequent than unilateral fusion and is reported to be 0.05%. Very few cases of fusion involving molar and premolar teeth have been reported in the literature. The cases of bilateral fused teeth are less frequent than unilateral and prevalence seems to be higher in the anterior region than in the posterior region. In this article we report a rare case of bilateral fusion of permanent maxillary second premolar with molar teeth.
