Abstract

Supernumerary teeth or hyperdontia are terms describing an excess in tooth number. It is an anomaly of developing dentition and has got multiple aetiologies. Mesiodens is the most common supernumerary tooth occurring in the palatal midline region. Supernumerary teeth, which duplicate the anatomy of normal dentition, are called supplemental teeth. This paper reports a rare non-syndromic case of a mesiodens associated with a unilateral, supplemental maxillary tooth and emphasizes the importance of thorough oral and radiographic examination and diagnosis of supernumerary teeth.
