Internal inflammatory root resorption was diagnosed in the mesial root of tooth 36 of a 40-year-old patient. In distal root, a hard tissue bridge had been formed between the pulp chamber and the root canal that seemed to be vital. No periapical destruction could be seen in the radiograph.

The pulp chamber and the mesial canal(s) were instrumented under local anaesthesia and packed with calcium hydroxide to necrotise the residual vital tissue. Two weeks later rest of the root canal system and resorption cavity were cleaned by instrumentation and sodium hypochlorite irrigation. New calcium hydroxide was packed in the tooth that was then sealed with zinc oxide eugenol and IRM filling.
