Mucosal fenestration an enigma - Case report

Abstract

Mucosal fenestration is a pathological condition characterized by perforation of the alveolar bone and overlying mucosa. It exposes the root to the oral cavity making them susceptible to deposition of plaque and calculus which in turn prevents the reformation of mucosal coverage. Predisposing factors include a thin cortical alveolar bone, buccally inclined root tip, chronic periapical inflammation and trauma. In this case report the mucosal fenestration defect w.r.t to 22 was treated using a multidisciplinary approach. Nonsurgical endodontic treatment was first performed to control the infection. Subsequent surgical intervention was performed to treat the bony dehiscence with apicectomy and a combination of guided tissue regeneration and bony graft for dehiscence and connective tissue graft for treating mucosal fenestration. Patient was followed for a year, the result showed complete closure of the mucosal fenestration defect.
