Multiple supernumerary premolars in two siblings: a case report.
The presence of three or more supernumerary teeth in one patient is uncommon. Genetic as well as environmental causes have been suggested as possible aetiological factors in the pathogenesis of supernumerary teeth. This report describes the dental findings and management of multiple supernumerary premolars in two siblings. The number and locations of the supernumeraries in both cases were almost identical. The findings from these cases give further support to the important role of genetic factors in the aetiology of supernumerary teeth. Primary care dentists who treat children should be aware of the possibility of familial occurrence of supernumerary teeth.
