Aim: This in-vitro study aimed to evaluate the shaping ability of hand K files, Kedo S, Hyflex, and the Race evo rotary files when used in the biomechanical preparation of primary molars by using CBCT. Materials and methods:One hundred forty extracted human primary mandibular second molars were randomly allocated into 4 groups of 35 each. Group A: Prepared with stainless steel hand files (MANI, Inc.; Tochigi, Japan), group B: Prepared with Kedo S plus pediatric rotary files (Chennai, Tamil Nadu, India), group C: Prepared with Hyflex cm (Colten-Whaledent) rotary files and group D: Prepared with Race Evo (FKG Dentaire SA, La Chaux de Fonds, Switzerland) rotary files. Before starting any procedure, all the samples were scanned using cone-beam CT (Gendex -GXDP-800, Kavo, Dental Charlotte United States). Pre-operative measurements were performed at 3 points at the middle one third of the distal root canals of the primary molars. Postoperative scans were obtained similar to a preoperative manner. The root canal thickness measurements were made at the same level of the preoperative readings.Results: Comparisons were made between the study groups' means. Data were compared using One Way ANOVA test followed by Tukey's Post Hoc test. The findings revealed no significant difference between any of the groups. Conclusion:No differences were noted concerning the shaping ability of the rotary systems used. Thus, all these systems could be used in instrumentation of primary molars.
