Comparative evaluation of postoperative pain after single sitting pulpectomy using hand and rotary instrumentation in primary molars of children – A randomized control study

AIM: The aim of the study is to evaluate and compare postoperative pain after single sitting pulpectomy using hand and rotary instrumentation in the primary molars of children. MATERIALS AND METHODS: Sixty children of age 4–8 years were selected using standard sample size formula for the single sitting pulpectomy after fulfilling inclusion and exclusion criteria and all participants were equally divided into two groups. Single sitting pulpectomy procedure was carried out in both groups. In the control group, K files and in the experimental group Pro AF baby gold pediatric rotary files were used, followed by obturation with zinc oxide-eugenol cement. Evaluation of postoperative pain was done using the modified visual analog scale at 24 h, 48 h, and 72 h. Furthermore, an evaluation of instrumentation time and quality of obturation was done. The patient is recalled after 7 days for the placement of stainless steel crown. RESULTS: The results showed no statistically significant difference in the postoperative pain after single sitting pulpectomy using hand and rotary instrumentation in the primary molars of children. There was no significant difference with the quality of obturation in both the study groups. However, a significant difference has been observed in the instrumentation time while using the rotary method of instrumentation as compared to hand instrumentation with independent t-test, t = 19.797 and P = 0.001. CONCLUSION: Among both the materials there was no significant difference found in postoperative pain and quality of obturation after single sitting pulpectomy in children. However, lesser instrumentation time was taken by rotary instrumentation as compared to conventional K file during single sitting pulpectomy in children.
