Persistent pain related to root canal filling and apical fenestration: A case report

Endodontic treatments may give rise to persistent pain whose origin is some times difficult to determine, Although it is unusual, pain may occur due to apical fenestrations following endodontic treatment. If this occurs, the s olution is surgical intervention. This surgical procedure consists of raisi ng a flap to expose the fenestration, followed by curettage of any overexte nded canal filling materials that may be potentially irritating to the unde rlying mucosa, remodeling of the apex, and its repositioning below the leve l of the cortical bone. A case is described that illustrates this clinical situation. The case also demonstrates information that can be obtained from tomodensitometric films.
