Clinical management of large perforating internal root resorption with collagen and mineral trioxide aggregate: Two case reports

Endodontic management of internal root resorption is challenging due to difficulty in debridement of the entire canal contents, disinfection, and control of the resorptive process. Often, there is no barrier to stop the repair material from being pushed into the periradicular tissues. In these case reports, we discuss the clinical management of internal root resorption, use of two forms of collagen used as a barrier material with mineral trioxide aggregate. – One-year follow-up of these cases reveals complete healing.
