Abstract

Periradicular surgery is a viable option to save natural teeth when non-surgical treatment fails or when endodontic retreatment is not feasible or contraindicated. Laboratory and animal studies have demonstrated that MTA is biocompatible, provides an excellent seal against penetrating bacteria, and promotes hard tissue healing. The purpose of this study was to provide long term (>3 years) clinical evidence for its use as a root-end filling material in endodontics. The clinical records of 294 patients who had MTA used during endodontic treatment from 1996 to 2001 were reviewed. From these, 75 patients whose root end cavities had been filled with MTA were identified for recall. Twenty five patients responded for clinical and radiographic evaluations providing a total of 27 eases. Clinical and radiographic exams were completed on these patients. Three independent examiners evaluated the radiographs for the presence or absence of pathological changes adjacent to the MTA restored site utilizing a Surgical Healing Index. Overall, twenty-two (81%) were considered healed, four (15%) were not healed, and one (4%) was classified as healing. The healed vs. not-healed outcome was statistically significant (p < 0.0001). Twenty-five (93%) of the recalled cases were functional and asymptomatic. Based on the results, it appears that the use of MTA should promote healing in a majority of surgical endodontic cases
