Successful Arrest of Internal Root Resorption Using Partial Pulpotomy: A Case Report.

This case report presents a novel, minimally invasive approach for treating internal root resorption (IRR) in a tooth diagnosed with symptomatic irreversible pulpitis and symptomatic apical periodontitis. A 32-year-old patient exhibited rapidly progressing IRR, along with apical radiolucency, one month after the initial diagnosis. Instead of conventional root canal therapy (RCT), a partial pulpotomy was performed using calcium-enriched mixture (CEM) cement with a tampon approach. Over a two-year follow-up period, apical radiolucency healed, with halting of the resorptive area. The root canals gradually narrowed, and no further pathology was detected, resembling the biological outcomes of successful pulpotomies. This case highlights the potential of tampon partial pulpotomy with CEM cement as an effective alternative to conventional RCT, offering improved preservation of pulpal vitality and favorable long-term outcomes.
