Abstract
Aim
This was to compare and evaluate the instrumentation time and quality of obturation between paediatric rotary file (Kedo-S) and manual instrumentation techniques in primary molars.
Methods
A double blinded randomised control trial was performed that included mandibular primary molars in children of age 4–7 years with pulp necrosis. Sixty primary mandibular molars were randomly divided into two groups: 30 were instrumented with paediatric rotary files Kedo-S (experimental group) and 30 with hand K-files (control group). During the preparation of the primary root canals the instrumentation time was recorded in seconds. The quality of obturation was recorded as optimal, under filled or over filled using immediate post-operative radiographs. The instrumentation time and quality of obturation were analysed using independent t-test and Chi-square test.
Results
Mean instrumentation time with paediatric rotary files Kedo-S (78.53 s) was significantly less than K-files (95.46 s) (p < 0.05). There was a significant improvement in the quality of obturation (p < 0.05) with paediatric rotary files (Kedo-S).
Conclusion
Clinical use of paediatric rotary files Kedo-S was effective during root canal preparation of primary teeth with reduction in instrumentation time and better quality of obturation.
