Bioceramics has significantly higher success rates than amalgam , but they were statistically similar to intermediate restorative material ( IRM ) and Super ethoxybenzoic acid ( Super EBA ) when used as retro grade filling material s in apical surgery .
However , it seems that the high success rates were not solely attributable to the type of the root-end filling material s. The surgical/microsurgical techniques and tooth prognostic factors may significantly affect treatment outcome
Introduction Periradicular surgery involves the placement of a root-end filling following root-end resection , to provide an apical seal to the root canal system .
Historically several material s have been used in order to achieve this seal .
Recently a class of material s known as Bioceramics have been adopted .
5-year results comparing mineral trioxide aggregate and adhesive resin composite for root-end sealing in apical surgery.
INTRODUCTION Recent meta-analyses of the outcome of apical surgery using modern techniques including microsurgical principles and high-power magnification have yielded higher rates of healing . However , the information is mainly based on 1- to 2-year follow-up data . The present prospect i ve study was design ed to re-examine a large sample of teeth treated with apical surgery after 5 years . METHODS Patients were recalled 5 years after apical surgery , and treated teeth were classified as healed or not healed based on clinical and radiographic examination . ( The latter was performed independently by 3 observers ) . Two different methods of root-end preparation and filling ( primary study parameters ) were to be compared ( mineral trioxide aggregate [ MTA ] vs adhesive resin composite [ COMP ] ) without r and omization . RESULTS A total of 271 patients and teeth from a 1-year follow-up sample of 339 could be re-examined after 5 years ( dropout rate = 20.1 % ) . The overall rate of healed cases was 84.5 % with a significant difference ( P = .0003 ) when comparing MTA ( 92.5 % ) and COMP ( 76.6 % ) . The evaluation of secondary study parameters yielded no significant difference for healing outcome when comparing subcategories ( ie , sex , age , type of tooth treated , post/screw , type of surgery ) . CONCLUSIONS The results from this prospect i ve nonr and omized clinical study with a 5-year follow-up of 271 teeth indicate that MTA exhibited a higher healing rate than COMP in the longitudinal prognosis of root-end sealing
