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 .
Outcomes of Endodontic Microsurgery Using a Microscope and Mineral Trioxide Aggregate: A Prospective Cohort Study
Introduction : The aim of this study was to investigate the outcome of endodontic microsurgery and analyze the prognostic factors . Methods : Our prospect i ve cohort study included 98 teeth in 81 patients . An endodontist performed all surgical procedures using endodontic microsurgical approaches . The treated teeth were recalled and examined clinical ly and radiographically at least 1 year after surgical treatment . The outcome was determined based on clinical and radiographic results . Radiographic healing was classified into 4 categories : complete , incomplete , uncertain , and unsatisfactory healing . An analysis of predictors was performed using multivariate logistic regression . Results : At recall , 74 of the 98 teeth ( 75.5 % ) were examined 12 to 30 months after surgery ; 71 of the 74 teeth were analyzed clinical ly and radiographically , and 3 teeth had been extracted . On periapical radiographs , 55 ( 74.3 % ) of the 74 teeth showed complete healing , whereas 12 ( 16.2 % ) demonstrated incomplete healing . Together the percentage of complete and incomplete healing was 90.5 % ( 67/74 ) , and all 67 teeth were clinical ly normal . Uncertain healing was observed in 3 teeth ( 4.1 % ) , one of which was symptomatic with swelling and sinus tract involvement and the other 2 were asymptomatic . The remaining 1 tooth ( 1.4 % ) showed unsatisfactory healing and was asymptomatic . The use as an abutment was found to be a negative factor associated with patient outcome ( P < .05 ; odds ratio = 22 ; confidence interval , 20.47–23.53 ) . Conclusions : The combined rate of complete and incomplete healing of teeth 12 to 30 months after endodontic microsurgery was 90.5 % . The use as an abutment may have a negative effect on treatment outcome
