Cystic Lesion on an Upper Premolar Related to Pulpotomized Deciduous Molar: A Case Report

Pulpotomy is a frequent endodontic treatment performed in children. Even though it is a safe procedure, side effects have been reported. A 10-year-old boy came for a dental checkup. X-ray findings showed a radiolucent lesion above the maxillary second primary left molar, related to the permanent tooth. Extraction of the first and second primary molars was realized under local anesthesia. The cystic lesion was removed surgically and histo-pathological analysis showed an inflammatory dentigerous cyst. A marsupialization cavity was created to allow eruption of the premolars. After a one-year follow-up, the bone had completely regenerated and premolars had completely erupted.
