Abstract

Aim: To compare and evaluate the instrumentation time and quality of obturation between paediatric rotary files and manual hand k-files
Materials and Methods: Sixty mandibular molars were randomly assigned to two experimental groups (n=30). Group I was instrumented using Kedo-S Square paediatric rotary files and Group II with manual hand K-files. Standardised 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. The quality of obturation was done using ANOVA and Chi square test with the level of significance set at 5%.
Results: Mean instrumentation time with paediatric rotary Kedo S Square files (72.6s) was significantly less than manual k-files (92.4s) (p< 0.001). There was a significant improvement in the quality of obturation (p<0.015) with paediatric rotary files (kedo-S Square). (Kedo-S) and manual instrumentation techniques in primary molars. (p < 0.05). There was a significant improvement in the quality of obturation (p < 0.05) with paediatric rotary files (Kedo-S).
Conclusion: Kedo-S Square rotary system provides better quality of root canal filling in minimum instrumentation time.
