ABSTRACT

Aim: To compare obturation quality between Hand K-files and Rotary Kedo-S files in primary mandibular molars. Method: A randomized clinical trial was carried on 30 patient aged between of 4–8 years requiring pulpectomy in primary mandibular molars. Patients were equal distributed for instrumentation with Hand K files and Rotary Kedo-S files. Results: With respect to quality of obturation among the groups, in Group 1 (Hand K files): 53.33 % of the canals were optimally filled; 26.66% and 3% were under and over filled, respectively. In Group 2 (Rotary Kedo S): 80.00% of the canals were optimally filled; 6.66% were under and 13.33% were over filled each. Conclusion: Rotary Kedo-S files have better obturation quality as compared to Hand K file.
