Interdisciplinary management of root perforation along with regeneration of bony fenestrations and dehiscence

Abstract

A surface alveolar bony defect communicating with the root canal perforation can be either endodontic or periodontal origin. Breach in the continuity of the cortical plate may lead to the development of dehiscence and fenestration alveolar defects. This case report discusses the regeneration of periodontal tissues in fenestration and dehiscence defects that had developed around traumatized incisors, using a type I collagen membrane and bone graft along with root perforation repair emphasizing the requirement of an interdisciplinary approach for the management of endodontic-periodontal lesions. The alveolar defects such as fenestration and dehiscences profoundly affect the prognosis of both periodontal and endodontic treatment outcomes; therefore, it should be carefully diagnosed and managed.
