Objective: The aim of this study was to evaluate the sealing capacity of three different sealants and to compare the sealing capacity of the three sealers. Study design: A Prospective Study. Location and Duration: In the Department of Operative Dentistry & Science of Dental Materials, Nishtar Institute of Dentistry, Multan for one year duration from June 2017 to June 2018. Methods: 30 first mandibular premolar teeth single rooted were used. At the cemento-enamel junction, the crowns were removed and preparations of root canals were done for the K # 35 file. The teeth were divided randomly into 3 groups as A, K and R. Each group consisted of 10 samples. Results: In Group A, AH Plus sealant, K group, Ketac-endo sealant and R group, Roth 801 sealant were used and using lateral condensation technique closed with gutta-percha. For one week, maintaining 100% humidity at 37 ° C, with nail polish the root surfaces were coated (spare the apex) and in a 2% methylene blue dye solution suspended for one week. In order to evaluate the following mean values of the dye penetration, the roots were divided into longitudinal sections, group A -2,675 mm, group K - 2,346 mm, group R - 4,929 mm. Conclusion: This analysis proves that Ketac-endo provides better sealing than the Roth 801 sealer. Key Words: Roth 801, Ketac-endo, AH Plus, Lateral Condensation, Apical sealing, root canal filling, dye Leakage
