Endodontic management of perforating internal resorption in a mandibular molar using sandwich technique.

Internal inflammatory root resorption is an uncommon pathology that can progress to the periradicular vicinity. It is frequently asymptomatic and only discovered during a radiological screening. Appropriate and timely diagnosis is extremely crucial in tackling these cases. A perforating internal resorptive cavity in the distal root of the mandibular first molar was successfully managed using a sandwich concept of sectional apical obturation with gutta-percha and Bioceramic sealer followed by the placement of mineral trioxide aggregate in the resorptive cavity.
