The endodontic sealants have an essential role in the root canal filling. The aim of this study was to analyse and compare three physio-chemical properties (pH, solubility, viscosity). The most significant decrease of the viscosity was for MTA-Fillapex, followed by Endoflas FS and Acroseal. The best behavior was recorded for Endomethasone N. The total decrease of dry mass (reported to baseline) was 0.0113 for Acroseal. Endoflas FS had a total decrease of dry mass of 0.0377 (from 0,6864 to 0.6487) during the study. The total decrease of dry mass (reported to baseline) was 0.0047 for Endomethasone N. MTA Fillapex had a total decrease of 0.0226 (from 0.4805 to 0.4579) during the study period. MTA Fillapex had the highest pH values (pH 10.16), followed by Acroseal (pH 8.79), Endoflas FS (pH 7.98) and Endomethasone N (pH 7.73).
