External root resorption is a lytic process occurring in the cementum and/ or dentine of the roots of teeth. Although till date the predisposing factor is yet to be discovered, the suspected causes are considered to be peri radicular inflammation due to trauma, granuloma, central jaw tumors, excessive forces, impaction of teeth, and systemic diseases. A 23 -year-old male reported to the department of conservative dentistry and endodontics with a chief complaint of pain and food lodgement in lower left mandibular region since 5-6 months. On clinical examination, grossly decayed tooth (#36) which was tender on vertical percussion and was not associated with any mobility. Intraoral periapical radiographic revealed external root resorption in distal root, which was concomitant with mild bone loss. Taking into account the extent and the severity of the resorption the treatment course was planned that included Root Canal Treatment. The distal and two mesial canals were obturated using mineral trioxide aggregate and gutta-percha respectively. After completion of obturation, it was followed by post endodontic composite restoration. The patient was followed-up after 1 year and the tooth was functional without sensitivity to percussion or palpation. Tooth showed normal physiologic mobility and no periodontal pockets on probing. Radiographic findings revealed no periapical changes and no further progression of External root resorption.
