Correction of mucosal defects of periapical origin with periodontal surgical techniques.

Author information

Department of Periodontology, Maurice and Gabriela Goldschleger School of Dental Medicine, Tel Aviv University, Israel.


Periapical lesions usually heal after successful root canal therapy. Persistent apical-oral communications may be due to anatomic and pathologic features that were originally linked to the endodontic cause of the lesion. One such factor is close proximity of the root apex to the oral mucosa. These defects necessitate corrective surgical intervention similar to techniques used in periodontal surgery. Four cases involving young female patients are described. These defects occurred in teeth that did not complete their maturation before necrosis of the pulp set in.
