Endodontic-periodontal management of a maxillary lateral incisor with an associated radicular lingual groove and severe periapical osseous destruction--a case report.

Radicular lingual grooves are morphological defects, which are found most frequently in maxillary anterior teeth and are a predisposing factor for periodontal disease. They are easily overlooked as aetiologic factors, as these grooves are covered by periodontal tissues. This case report presents a successful management of a case of a maxillary lateral incisor with an associated radicular lingual groove and severe periapical osseous destruction in a 30-year-old female patient. A combination of endodontic treatment, radiculoplasty to eliminate the radicular lingual groove, and periapical surgery to eliminate the periapical osseous defect was used. At two-year follow-up, the patient was comfortable and complete resolution of the periapical pathology was evident.
