Abstract
Introduction: Biomechanical preparation using conventional hand files or rotary files plays a significant role in the pulpectomy procedure. The objective of this study was to compare the post-operative pain after root canal instrumentation with Kedo-S Square rotary files, hand H-files and K-files in primary molar teeth. Materials and methods: A randomized clinical trial was performed on 45 primary molars equally distributed for instrumentation with Kedo-S Square files, H-files and K-files. After completion of pulpectomy, the post-operative pain was evaluated at intervals of 6, 12, 24 and 48hours using modified Wong Baker pain scale and compared between the groups. Results: In all three groups, the highest post-operative pain scores were recorded at 6-hour interval and decreased over time.
