This study evaluated the apical sealing ability of root canals obturated with Thermafil and Obtura II heated gutta percha system in comparison with conventional cold lateral condensation by using Fluid filtration system. 55 extracted human mandibular first premolars were collected and these teeth were randomly divided into three groups of 15 specimens each. (Group I - Cold lateral condensation, Group II – Thermafil, Group III - Obtura II heated gutta percha system). Profile Ni-Ti instruments were standardized to perform biomechanical preparation in all the groups. Top seal, an epoxy based sealant was employed as the common sealant. The group I comprising of Cold lateral condensation leaked the most in comparison with the other test groups, which was followed by group III (Obtura II) with moderate leakage and group II (Thermafil) with least micro leakage.
