Endodontic and periodontal treatment of an external cervical resorption

External root resorption can be divided into 3 categories: 1) progressive inflammatory resorption; 2) cervical resorption; and 3) replacement resorption. Cervical resorption is a not well recognized type of progressive external inflammatory resorption. It occurs after injury to the cervical attachment apparatus, mostly in the area of the cervical root surface (precementum) below the epithelial attachment. The present article describes an abnormal case of cervical resorption in a vital lateral maxillary incisor of a 27-year-old male patient. Endodontic treatment and subsequent periodontal plastic-esthetic surgery were performed. Reconstruction of the defect was achieved using mineral trioxide aggregate cement. After 2 years, the tooth showed no pathologic symptoms. The present case demonstrates a novel combined endodontic and periodontal treatment of an external root resorption.
