All data [age, sex and systemic disease or syndrome] were obtained from the patient files and analyzed for double teeth [fusion and geminaiton]. The distribution of double teeth was investigated according to types and clinical positions. In this study the prevalence of double teeth [Fusion and gemination] in the permanent dentition in patients between 12 to 60 years was 0.29%. 14 [0.17%] were Fused and 12 [0.14%] were geminated teeth.
