Role of mineral trioxide aggregate: In periodontal regeneration over root resorption Area - A case report

Mineral Trioxide Aggregate (MTA) is a recent restorative material. It has shown a very good potential as a reparative material for perforation because of its biocompatibility, regenerative capacity and excellent sealing ability. A cementum-like material has been consistently shown to grow directly on the material after placement. Due to these properties, it was attempted to seal the resorption site on a tooth root of # 21, having perio-endo lesion in a 44-year old patient.Patient had non-vital # 21 due to trauma one year back. After biomechanical preparation, open flap debridement was planned, During surgery, resorption site was sealed with MTA. Osseous graft and collagen membrane were placed over it. Post surgically, after initial recession, there was gingival creeping associated with evident increase in the crestal bone height radio graphically.Henceforth, a case of external root resorption communicating the periodontal pocket with the pulp Space leading to perio-Endo lesion and its management is presented.
