Aim: The aim of the study is to evaluate the disinfection efficacy of the root canals with three different irrigation systems namely, Manual Dynamic Agitation, Ultra X and Laser.

Materials and Methods: Forty extracted mandibular premolar teeth were decoronated at cemento-enamel junction and root canals were prepared till #30k file and saline was used as irrigant. Two coats of nail varnish was applied to seal the apex. The teeth were sterilized and inoculated with bacterial strains of E. faecalis and incubated for 21 days at 37°C. The samples were randomly divided into 4 groups (n = 10) according to the irrigation systems used, 5.25% NaOCl was used as irrigant in experimental groups, and control group received no irrigation. After root canal disinfection, the paper points were used to collect the samples from the teeth and were placed in Brain Heart Infusion Broth for 24hours. Then the samples were transferred to Muller-Hilton media for 24 hours to evaluate the colony forming units.

Statistical Analysis: Statistical analysis performed using chi-square test.

Results: According to the results obtained, Laser irradiation resulted in better disinfection of the root canal system. Ultra X resulted in significant disinfection as compared to Manual Dynamic Agitation.

Conclusion: Within the limitations of the study, Laser irradiated group showed better disinfection than Ultra X and Manual Dynamic Agitation when used in conjunction with 5.25% sodium Hypochlorite.
