Mesiobuccal root resection in endodontic-periodontal combined lesions.

AIM: To present two successful cases involving management of endodontic-periodontal combined lesions with root resection and guided tissue regeneration (GTR) therapy.

SUMMARY: Mesiobuccal resection surgery was performed concomitant with GTR therapy to manage endodontic-periodontal combined lesions on teeth 17 and 26. The increased mobility after the periodontal surgery gradually decreased during the healing period. At 15 and 20 month follow-ups, respectively, the teeth showed no mobility, 2-3 mm pocket depths and no further bone loss.

KEY LEARNING POINTS: Treatment of periodontally involved maxillary teeth creates unique challenges, given the presence of furcations, root proximities and the maxillary sinus. Root resection combined with GTR therapy can enable tooth maintenance with a good long-term prognosis.
