A Randomized Controlled Study of Mineral Trioxide Aggregate and Super Ethoxybenzoic Acid as Root-end Filling Materials in Endodontic Microsurgery: Long-term Outcomes.
INTRODUCTION The purpose of the present study was to evaluate the long-term clinical outcome of endodontic microsurgery when mineral trioxide aggregate ( MTA ) and super ethoxybenzoic acid ( Super EBA ; Harry J. Bosworth , Skokie , IL ) were used as root-end filling material s. Additionally , this study aim ed to compare the clinical outcome of endodontic microsurgery at the 1-year follow-up with that at the 4-year follow-up . METHODS Two hundred sixty teeth were r and omly assigned to either the MTA or Super EBA group in equal numbers using the minimization method . Endodontic microsurgery was performed according to the Yonsei protocol . The previous study of 192 teeth examined at the 1-year follow-up revealed a success rate of 95.6 % for MTA and 93.1 % for Super EBA . Patients were recalled 4 years after surgery , and treated teeth were classified as successes or failures with Molven 's criteria . The Pearson chi-square test and the McNemar test were conducted to analyze and compare the success rates . RESULTS A total of 182 teeth were examined at the 4-year follow-up . The success rate was 91.6 % for MTA and 89.9 % for Super EBA . Statistical analysis of the success rate did not show any significant difference between the 2 material s ( P = .8 ) . The overall success rate at the 4-year follow-up was 89.5 % , which was slightly lower compared with 94.3 % at the 1-year follow-up . However , there was no significant difference between the follow-up periods ( P = .063 ) . CONCLUSIONS This study identified no significant difference in the 4-year success rates of MTA and Super EBA as root-end filling material s in endodontic microsurgery . Additionally , compared with short-term outcomes , long-term follow-up outcomes were not significantly different
On the basis of available evidence , MTA presented good marginal adaptation to dentine walls .
