      Abstract

      The dental literature concerning the bilateral presentation of fusion and gemination is reviewed and analyzed. Tables are presented to show the prevalence and distribution of these anomalies in both the primary and permanent dentitions. In addition, the first prevalence statistics for the bilateral occurrence of fusion and gemination in the primary and permanent dentitions are determined. The first case of bilateral fusion of mandibular primary incisors to be reported in 13 years is presented. The presence of all four succedaneous incisors and the diagnosis of bilateral fusion are confirmed radiographically. The developmental concerns and possible sequelae of bilateral fusion and gemination are also discussed.
