Use of cone-beam computed tomography as a diagnostic aid in nonsurgical endodontic management of furcation perforations: Two case reports

Abstract

Iatrogenic furcation perforation is undesirable communication between the pulpal floor and the periodontium. This study reports nonsurgical endodontic management of iatrogenic furcation perforation in mandibular molars in two cases. Cone-beam computed tomography (CBCT) was used as an advanced diagnostic aid to accurately determine the location and extent of the perforation. The perforation was sealed with mineral trioxide aggregate, and the teeth were treated endodontically. Since the pulpal floor was weakened due to perforations, attempt was made to reinforce the coronal tooth structure using composite resin. Full crowns were placed as a definitive restoration. Two-year postoperative follow-up showed the absence of pain or swelling clinically, and radiographic examination revealed complete healing of furcation lesion. The use of CBCT in this report was a valuable diagnostic aid, which helped in better treatment planning and improved treatment outcome for the patient.
