Nonsyndrome Multiple Supernumerary Teeth: A Cone- Beam CT Case Report

Hyperdontia or supernumerary teeth are defined as teeth that are more than the usual number of 20 deciduous and 32 permanent teeth, regardless of their locality and form. Supernumerary teeth may occur singly, multiply, unilaterally, or bilaterally and in one or both jaws. Multiple supernumeraries occur in less than 1% of cases and their occurrence can create a variety of clinical problems. A 26- year-old female patient was referred to the department of oral diagnosis and radiology, dental faculty of Isfahan Medical University, Iran for initial dental examination which involved taking a panoramic radiograph. The panoramic radiograph revealed the presence of seven impacted multiple supernumeraries in all four quadrants. For precise localization of these teeth before extraction surgery, we took a cone-beambeam CT. The impacted supernumerary teeth in each mandibular and maxillary quadrant were surgically removed under local anesthesia. Prophylactic surgical removal of the supernumerary teeth, with resolution of complications, is generally an optional treatment. To precisely localize a tooth before surgery, a cone-beambeam CT should be taken.
