The goal of this in vitro study was to evaluate the relative biocompatibility of four endodontic sealers on the cell culture of the human fibroblast through cytotoxicity. Materials and Methods: In this study four endodontics sealers was used GuttaFlow (Roeko)silicone based sealer, AH plus (De Tray-DENTSPLY) epoxy resin based, Apexit (Vivadent) calcium hydroxide based and Endorez (Ultradent) methacrylate based sealer. Sealers were tested on primary cell lines of human gingival fibroblasts. Experiments were preformed in laboratories of Hacettepe University of Ankara, Turkey and Faculty of Dentistry, University of Sarajevo, Bosnia and Herzegovina Cytotoxicity was determinate using WST-1 assay. Results: Results were analyzed by SPSS 19 program. Kolgomorov-Smirnov test, Shapiro-Wilk and descriptive statistics also were used, as well as Kriskall-Wallis, ANOVA test and T- test. According to our results all four sealers showed different cytotoxicity effects on human gingival fibroblast cell culture, but all of them are slightly cytotoxic. Conclusions: According to results of this study it can be concluded: all four sealers showed different cytotoxicity effects on primary cell lines of human gingival fibroblasts, but all of them are slightly cytotoxicity.
Key words: four root canal sealers, cytotoxicity, human gingival fibroblasts.
