The purpose of this study is to evaluate periapical healing using IRM as a retrograde filling material. Twenty patients who had indications for apicoectomy and root end filling material were evaluated clinically and radiographically for one year, at an interval of 3 months, 6 months 9 months. Intermediate restorative material was frequently used as a retrofilling in the past and now it is being replaced by newer materials like MTA and Biodentine. IRM was used in this study, as it is economical and numerous studies in literature showed no statistical difference in periapical healing when MTA and IRM was used as retrofilling.
