Purpose
To compare the post-operative pain after root canal instrumentation with hand K-files, H-files and rotary Kedo-S in primary teeth.
Method
All 4–6-year-old children were invited and 69 agreed to participate. The participants were randomly divided and distributed for instrumentation with K-file (Group 1), H-file (Group 2) and rotary Kedo-S files (Group 3). After completion of root canal procedure, the post-operative pain was evaluated at intervals of 6, 12, 24, 48, and 72 h using modified Wong-Baker pain scale and compared between the groups.
Results
Post-operative pain between three groups at 6, 12, 24, 48 and 72 h was compared using Chi square test. There was decreased post-operative pain with Kedo-S rotary files as compared to other two groups (P value < 0.001). The post-operative pain decreased after 12 h for all the groups with no pain at 24, 48 and 72 h intervals.
Conclusion
Paediatric rotary files Kedo-S showed significantly less post-operative pain as compared to K-file and H-file at 6 h and 12 h intervals. However, follow-up interval of 24, 48 and 72 h showed no significant difference between the rotary and hand file groups.
