Abstract

This article describes 2 unusual cases of mucosal fenestration associated with necrotic infected teeth, resulting in exposure of the root apex to the oral cavity. Both cases consisted of maxillary incisors with pulp necrosis and radiographic/tomographic evidence of apical periodontitis. Clinically, the root apex was exposed to the oral cavity through a fenestration in both bone and mucosa and covered with bacterial plaque and calculus. These teeth were treated by a combination of nonsurgical and surgical endodontic treatment. During surgery, the root apices were resected to within the alveolus and the fenestrated area covered by the flap. Specimens consisting of the root apex and surrounding soft tissues were subjected to histopathological and histobacteriological analyses. Histobacteriological analysis revealed extensive resorptive defects on the root apices filled with thick bacterial biofilm, irregular detachment of the cementum layers with consequent infection of the underlying spaces, and heavy infection in the apical foramina. The soft tissue specimens exhibited no or minimal inflammation. The 2 cases showed satisfactory postsurgical healing of the hard and soft tissues. Both cases of mucosal fenestration showed root apic...Continue Reading
