【 摘 要 】

Hermetic sealing of the apical area after root end resection is essential to the success of endodontic surgery. To compare microleakage after root end resection of the two bioceramic sealers without retrograde filling - Total Fill BC Sealer and MTA Fillapex, and two materials for retrograde filling-MTA and Biodentine, using the method of penetration of dye - 2% methylene blue. Forty eight extracted single-rooted human teeth were used in this study. The resection was made at 3 mm from the root tip at an angle of 90 degree to the long axis of the tooth. The teeth were divided into 4 groups: 1st group (n = 9) - root canal obturation with Total Fill BC Sealer without retrograde filling; 2nd group (n = 8) - root canal obturation with MTA Fillapex without retrograde filling. 3rd group (n = 10) - retrograde ultrasonic cavity preparation and filling with MTA. 4th group (n = 8) - retrograde ultrasonic cavity preparation and filling with Biodentine. The outer surface of the root was covered with two layers of varnish, with the exception of the apical 3 mm and then immersed in 2% methylene blue for 72 h. The degree of penetration of the dye is measured in millimeters. The data was entered and processed with the statistical package IBM SPSS Statistics 22.0. We reject the null hypothesis when p < 0.05. With significantly higher value is the arithmetic mean of the group with the root canal obturation with Total Fill BC Sealer without retrograde filling - 2,01 mm; versus a retrograde filling with MTA - 0,68 mm and Biodentin - 0,51 mm; and no statistically significant difference with the group root canal obturation with MTA Fillapex - 1,76 mm. In the four material microleakage dye was observed, but to varying degrees.
