摘要：Synodontia or fusion is a developmental anomaly of shape of tooth formed by union of two independently developing primary or permanent teeth. Fusion may be either complete or incomplete depending on the stage of development. The overall prevalence of the tooth fusion is approximately 0.5% -2-5% in deciduous teeth and 0.1% in permanent dentition. The exact aetiology is not clear, but it is thought that some pressures or physical forces may cause the contact of developing teeth. The case report presented here highlights a case of fusion between permanent mandibular central incisor with lateral incisor in a male patient.
