Background: Pulpectomy is the treatment of choice for severely infected primary molars. The aim of the study is to evaluate the instrumentation time and obturation quality using Kedo SG blue, Kedo SH, and reciprocating hand K files in primary mandibular molars. To evaluate the instrumentation time and obturation quality using Kedo-SG blue, Kedo-SH, and reciprocating hand K-files in primary mandibular molars. Materials and Methods: A double-blinded randomized controlled trial was conducted on 45 mandibular molars and were randomly assigned to three experimental groups (n = 15). Group I was instrumented using Kedo-SG blue pediatric rotary files, Group II with Kedo-SH pediatric hand files, and Group III with reciprocating hand K-files. Standardized digital radiographs were taken before and after root canal instrumentation. Root canal preparation time was also recorded. Statistical analysis of the obtained data was done using SPSS software version 17.0. An intergroup comparison of the instrumentation time and the quality of obturation were done using ANOVA and Chi-square test with the level of significance set at 5%. P < 0.05 was considered statistically significant. Results: No significant differences were noted with regard to the quality of obturation between the three groups (P < 0.14). However, a statistically significant difference was noted in the instrumentation time between the three groups (P = 0.000). Kedo-SG blue rotary file had significantly lesser instrumentation time when compared to that of Kedo-SH hand files and reciprocating hand K-files. Conclusion: On comparative evaluation, Kedo-SG blue pediatric rotary file showed a marked reduction in instrumentation time, followed by Kedo-SH pediatric hand files and reciprocating hand K-files.
