Ectopic supernumerary teeth as a predisposing cause in localized periodontitis. Case report

Supernumerary teeth are relatively common in the maxillary incisor and molar areas. However, bilateral ectopic, fully erupted supernumerary mesiodentes are relatively rare. The present case documents a patient with localized periodontitis of the maxillary first and second molars associated with bilaterally erupted supernumerary teeth located in proximity to the buccal embrasure space between the molars. Combined clinical data suggested that these ectopic mesiodentes predisposed or contributed to the development of localized periodontitis.
