Bilateral double teeth—A case report

Abstract

Developmental anomalies can occur as a result of conjoining or twinning defects. These include fusion, gemination and concrescence. Such anomalies occur more often in the deciduous than in the permanent dentition and only a few cases involving molar and premolar teeth have been reported in the literature. Cases of bilateral double teeth are less frequent than unilateral and prevalence seems to be higher in the anterior region. The present article is a rare case report of simultaneous occurrence of double teeth in permanent dentition involving the mandibular premolar-molar teeth in a 45-year-old male patient. Clinical observation along with radiographic examination was used to arrive at a diagnosis.

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

“…Fusion is the union of two normally separated tooth germs. Depending upon the stage of development it may be either complete or incomplete (1). The aetiology of fusion is still not clear, but the influence of pressure or physical forces producing close contact between two developing teeth has been reported as one possible cause (5).…”

“…Fusion of teeth refers to the union of two normally separated tooth germs and depending upon the stage of development of the teeth at the time of union, it may be either complete or incomplete (1) Fusion can occur between teeth of the same dentition or mixed dentitions and between normal and supernumerary teeth (2,3) . Only a few cases of fusion involving molar and premolar teeth have been reported (4) In both dntitions, the prevalence is higher in the anterior region than in the posterior region [2,3]…”
