Bilateral presentation of different supernumerary teeth in nonsyndromic patients: case reports

Supernumerary teeth--teeth in excess of the normal dental complement--are usually asymptomatic, and their presence is detected incidentally on radiographs. Mesiodentes are the most common type of supernumerary teeth, followed by maxillary distomolars, maxillary lateral incisors, mandibular fourth molars, and maxillary premolars. Bilateral occurrence of supernumerary teeth is rare. When supernumerary teeth do occur bilaterally, they are most often associated with a syndrome such as Gardner syndrome or cleidocranial dysostosis. This article presents case reports of 4 nonsyndromic patients with different forms of bilateral supernumerary teeth: bilateral mesiodentes, bilateral paramolars, bilateral distomolars, and bilateral parapremolars. The supernumerary teeth were managed by extraction or clinical and radiographic monitoring.
