Guided tissue regeneration in endodontic – periodontal lesion: A case report

Clinicians often have diffïculty in the diagnosis and treatment of the combined endodontal and periodontal lesion in private practice. This case report demonstrates that proper diagnosis followed by etiological factors and utilizing the guided tissue regeneration technique combined with osseous grafting, will restore health and function to a tooth with severe attachment loss caused by an endo-perio lesion. This case report demonstrates a case of an endodontic –periodontal combined lesion on a maxillary left central incisor was first treated with conventional endodontic therapy. Periodontal surgery was then completed which include scaling and root planning and apical curettage on the tooth. The facial bony defect was then filled with a alloplastic graft material which was later covered by resorbable GTR membrane and periodontal flap sutured over this. This combined treatment resulted in minimunm probing deptli (3mm),maximal cllnlcal attachment gain (8mm),as well as radiographie cvidcncc of alveolar bone gain.
