Treatment of advanced periodontal breakdown as a result of endodontic lesion is a challenge for the practitioner. Guided tissue regeneration (GTR) is an established treatment option in such cases, along with endodontic surgery. A few recent studies have reported favorable outcome for treatment of apicomarginal defects without using GTR. Such an option helps prevent disadvantages of using barrier membrane. This case report presents favorable outcome of a mandibular molar with large periapical pathology and apicomarginal defect and grade II mobility treated by endodontic surgery without using GTR.
Key words: Surgical endodontics, apicomarginal, GTR.
