Abstract: Three bioceramic sealants (endosequence BC sealant, endoseal MTA and MTA fillapex) and three epoxy based sealants (AH Plus, ad seal and radic sealant) were tested to evaluate their physicochemical properties: fluidity, final setting time, radiation resistance, dimensional stability and pH change. The data were analyzed by one-way ANOVA and Tukey s post test (). The flow of MTA fillapex sealant was the highest, and the flow of BC sealant was significantly lower than that of other sealers (). Even after one month, BC sealant and MTA fillapex samples were not placed in wet incubator conditions. Among the measurable materials, endoseal MTA has the longest setting time, and radic sealer and ad seal have shorter setting time than ah plus (). Ah plus and endoseal MTA showed statistically higher values MTA Fillapex showed statistically lower radiopacity (). BC Sealer showed the highest alkaline pH in all evaluation periods. Set samples of 3 epoxy resin-based sealers and EndoSeal MTA presented a significant increase of pH over experimental time for 4 weeks. In conclusion, the bioceramic sealer and epoxy resin-based sealers showed clinical acceptable physicochemical properties, but BC Sealer and MTA Fillapex were not set completely.
