Fusion Presenting As Gemination-A Rare Case Report

Odontogenic anomalies can occur as a result of conjoining or twinning defects. These include fusion, gemination and concrescence occurring in both primary and permanent dentition. Double tooth is a term used to describe connate tooth and includes both dental fusion and gemination. The phenomenon of gemination occurs when two teeth develop from one single bud leading to a larger tooth. Fusion is a condition in which the crowns of two separate teeth have been joined together during the crown development. Fusion occurs infrequently but could cause esthetic, spacing and periodontal problems. The present article highlights the presence of double teeth in a 44 year old man clinically presenting as gemination, but on radiographic evaluation turned out to be fusion. Correct diagnosis of the condition implicates in a better prognosis for the patient.
