Management of Internal Root Resorption With Mineral Trioxide Aggregate in Mandibular Molar: A Case Report.

Internal root resorption (IRR) is a pathological condition characterized by the loss of dentin due to the action of clastic cells triggered by pulpal inflammation. Most cases of internal root resorption occur in anterior teeth, primarily because of their susceptibility to trauma. However, it can also manifest in posterior teeth, often as a result of carious involvement of the pulp. Timely diagnosis, elimination of the underlying cause, and appropriate treatment of the resorbed root are essential for achieving a successful treatment outcome. Various techniques and materials have been employed to fill internal resorptive defects. Among these, mineral trioxide aggregate (MTA) demonstrates commendable properties, including biocompatibility, effective sealing ability, mechanical strength, and the capacity to promote healing of periradicular tissue. This case report presents the successful management and favorable outcome of internal root resorption in a mandibular molar through non-surgical endodontic treatment and repair of the resorptive defect using MTA.
