Evaluation and Comparison of Effectiveness of Kedo-S Pediatric Rotary Files vs Manual Instrumentation for Root Canal Treatment in Primary Molars

PURPOSE: To evaluate and compare the clinical and radiographic success of Kedo-S pediatric rotary files vs manual K-Files for pulpectomy in primary mandibular molars. MATERIALS AND METHODS: A sample of 30 primary mandibular molars with irreversible pulpitis was taken per group. The groups were divided as below mentioned—group I (n = 30) was treated using the Kedo-S file system. Group II (n = 30)—treated using manual stainless steel K-File. The clinical and radiographic success was compared of both techniques. Statistical analysis involved t-test, Chi-squared test, and Cochran's Q test. RESULTS: The overall clinical success at 3, 6, and 9 months in group I were 72.4, 89.7, and 93%, respectively and in group II were 82.1, 92.9, and 92.9%, respectively. The overall radiographic success in group I at 3, 6, and 9 months were 6.9, 17.2, and 69%, respectively and in group II were 0, 7.1, and 35.7%, respectively. According to the Frankl behavior rating scale, 19 children in group I (65.5%) showed negative behavior, and 15 children in group II (53.57%) showed positive behavior. The mean instrumentation time in group I (Kedo-S pediatric rotary file group) and group II (hand K-File group) was 8.03 ± 0.823 and 11.25 ± 0.928, respectively. CONCLUSION: There was a statistically significant/highly significant difference in intergroup comparison postoperative behavior among the children in the two study groups. There was a statistically significant difference between the two study groups with relation to instrumentation time. The trend that was observed in the clinical and radiographic profile was that group I (Kedo-S rotary files) cases had more success when absolute numbers and figures were compared than group II (hand stainless steel K-File) in which success rates were comparable; however, the difference between the groups were found to be statistically nonsignificant.
