Abstract

Supernumerary teeth occur in 0.9-2.6％ of cases and most frequently in the maxillary anterior or molar region. The presence of bilateral supernumerary teeth in the mandibular third molar region is rare. Here, we report a case of bilateral impacted supernumerary teeth in this region. The patient was a 27-year-old man who presented to our hospital with the chief complaint of right mandibular second molar pain. Radiological examination showed radiolucency around the right mandibular second molar root and odontoid radiopacity in the mandibular third molar region bilaterally. We diagnosed apical periodontitis of the right mandibular second molar and bilateral mandibular horizontal impacted third molars associated with impacted supernumerary teeth. We extracted the right mandibular second molar, both mandibular third molars, and the impacted supernumerary teeth with the patient under general anesthesia. The postoperative course was uneventful and the patient remains well 17 months after surgery.
