Introduction: Pulpectomy is the only viable option to retain a primary tooth with irreversible pulpal pathosis in its position until physiological exfoliation. Biomechanical preparation is the major step in determining the success of pulpectomy. In the field of pediatric endodontics, there has been a progression with the type of instruments used for canal preparation. Aim: To compare the quality of obturation, instrumentation time
and post-operative pain after pulpectomy in primary molars using manual K-files, Kedo-S square and Kedo-S Plus rotary file systems.Materials and methods: A double blinded randomized control trial was conducted in 45 children of 4 and 8 years age groups, indicated for pulpectomy in any of the primary mandibular molars. The children were divided into 3 groups with 15 teeth in each. Canal preparation was done using hand K-files,
Kedo-S Square files, and Kedo-S Plus. The time taken for instrumentation was recorded using a stopwatch. The quality of obturation was evaluated using post-operative radiograph, and post-operative pain was assessed with modified Wong-Baker FacesPain scale. Clinical and radiographic evaluation at 3, 6 and 12 months was assessed using Modified Criteria By American Association Of Endodontists (1994). Results and discussion: 45 children, 28 males and 17 females, participated in the study; the mean age of participants was 5.52 ± 2.48 years. Instrumentation time was minimum in rotary Kedo-S
Plus files (57.53 ± 5.16), followed by Kedo-S Square files (77.80 ± 7.58). The preparation time was maximum with manual K-files (128.86 ± 6.72). Kedo-S Plus files provided a higher number of optimally filled canals (100%) and also had the highest number of clinical and radiographic success. Rotary files Kedo-S Square followed by Kedo-S showed less post-operative pain compared to K-files. Conclusions: The use of Kedo S Plus pediatric rotary instruments for canal preparation during pulpectomy results in better quality of obturation evaluated over time, having significantly less post operative pain as well as less instrumentation time, compared with other rotary file systems and Gold standard Hand K Files.
