Management of furcal perforation with advanced furcation defect by a minimally invasive tunnel technique

A perforation in the furcation area is a potential risk factor for extension of pulpal inflammation into the periodontium and formation of advanced furcation defect with severe loss of clinical attachment and interradicular bone. Furthermore, the management of such furcal perforation is difficult due to poor accessibility, visibility, and regenerative potential. The development of such advanced furcation defects further compromises the prognosis of the treatment as they preclude effective plaque control and maintenance by the patient. Therefore, the management of advanced furcation defects remains an enigmatic and challenging task for the clinician. This case report describes a minimally invasive approach for the treatment of a furcal perforation by a conservative tunnel preparation. The present case report aims to highlight the importance of surgical tunnel preparation as an alternative to conventional flap procedure to repair furcal perforation with advanced furcation defects.
