Abstract

Aim: To evaluate the clinical efficacy of pediatric rotary files and compare it to manual K-files.
Materials and Methods: Thirty-six second primary molars in 26 children aged 4-7 years were allocated into three groups according to the instrumentation system received as follows (n=12 teeth / group): Group 1, Kedo-S plus file, Group 2, Kidzo file and Group 3, manual K-file. Each molar underwent a single-visit pulpectomy; instrumentation time was documented, and the quality of the obturation was evaluated using immediate postoperative periapical radiographs. After that, the results were statistically assessed.
Results: Kedo‑S plus (Group 1) file required the least instrumentation time followed by Kidzo files (Group 2) and K‑files (Group 3) subsequently and the difference was statistically significant (p<0.001). Optimum quality of obturation was achieved using Kedo-S plus file (Group 1) followed by Manual K-files (Group 3) and Kidzo files (Group 2) subsequently and the difference was not statistically significant (p=0.665).
Conclusion: The rotary file Kedo-S plus had the fastest time of instrumentation and improved obturation quality.
