Abstract
Supernumerary teeth are defined as those in addition to the normal series of deciduous or permanent dentition. Supernumerary teeth are more prevalent among males and in the permanent dentition. The exact etiology of supernumerary teeth is unknown, they may occur anywhere in the oral cavity. They may appear as a single tooth or multiple teeth, unilaterally or bilaterally, erupted or impacted in maxilla or both jaws.
Fourth molars, also called distomolars, are a variant in shape and number appearing as alterations during odontogenesis. They can be eumorphic or dismorphic, single or multiple, erupted or impacted, unilateral or bilateral, and can appear in both jaws. They are of unknown etiology, but there are several theories to justify these tooth alterations such as dental lamina duplication, its horizontal proliferation or its hyperactivity.
Hereby, we are presenting a unique case report of presence of three distomolars in a single patient at maxillary left side and mandibular right and left side.
