defined gemination as the formation of the equivalent of two teeth from the same follicle, with evidence of an attempt for the teeth to be completely separate, this indicated clinically by a groove or depression which could delineate two teeth. Gemination, Fusion, Concrescence and Twinning are developmental anomalies affecting the shape of the teeth. Geminated teeth arise from an attempt at division of a single tooth germ by an invagination. The resultant structure is a single tooth with two completely separated crowns or large, incompletely separated crown that have single root and root canal. It is seen in permanent as well as in deciduous dentition.There is an overall prevalence2 of 0.5% in deciduous dentition, 0.1% in permanent teeth and 0.02% in both dentition.
