Background: It is generally accepted that long-term endodontic success is dependent upon the ability to seal the peri-apical tissues from communication with the canal system. The present study was planned for comparison of conventional and mechanical lateral condensation techniques in the density of endodontic obturations. Material and methods: The study was conducted in the department of Conservative dentistry and Endodontics of dental institution. For the study, we selected 20 extracted human premolar teeth with single canal and completed apex. The crowns of the teeth were cut off using a slow speed disc bur. The working length of all the teeth was standardized to 19mm. Biomechanical preparation (BMP) of the roots was done using hand K-files. The apex was prepared up to size 30 K file with step back preparation up to size 50 K-file. Results: The mean weight of gutta percha for Group LC was 7.63 + 0.002 g and Group MLC was 11.02 + 0.006 g. Conclusion: MLC technique is superior to conventional lateral condensation technique in obturation of endodontic canals.
