| Abstract | ||||
| 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. | ||||
