Abstract
Aim: The aim of this study was to evaluate the incidence of post-operative pain after cleaning and shaping with three file system using Hand, Rotary and Reciprocating motion in maxillary and mandibular molars. Materials and Method: A total 60 patients were randomly divided into 3 groups: in group 1 (n=20) teeth were prepared with hand protaper file system till F2 size. In group 2 (n=20) teeth were prepared with primary wave one gold and in group 3(n= 20) teeth were prepared with protaper gold file system till F2 size. The pre and post-operative pain score was noted using visual analog scale at 12, 24, 48 and 72 hours after preparation. Results: all the pre instrumentation pain values were higher than post-instrumentation. There was significant difference among the groups with highest post-operative incidence in wave one gold followed by hand protaper and protaper gold files after 12 hours. Conclusion: Post- operative pain was significantly lower in patients treated with rotary protaper gold as compared to wave one gold and hand protaper file systems.
