The introduction of the rotary file system for children was a revolution in the field of pediatric endodontics. These files are cost-effective and help in consistent obturations with shorter instrumentation time.
The present randomized controlled trial (RCT) was planned for a comparative evaluation of rotary and manual techniques in biomechanical preparation of primary molars to determine their effect in terms of cleaning and shaping efficacy, working time, quality of obturation, and postoperative pain.
A randomized clinical trial study was conducted in 75 children aged 5-9 years requiring pulpectomy. Each tooth was randomly assigned to one of the three treatment groups: Kedo-S files, rotary K-Flex files, and hand instruments group.
It was observed that Kedo-S files and rotary K-Flex files were more effective in cleaning and shaping of root canals compared to hand H/K files. The postbacterial count for hand files was higher compared to rotary files. Shorter working time was seen with rotary files (3.88-5.04 minutes) compared to hand files (15.68 minutes). Rotary files showed a reduced number of voids, with Kedo-S files in 92% of cases and rotary K-Flex files in 80% of cases. Apical seal and extent of fill were maximum with rotary files, having a grade C rating in 92% of cases. Kedo-S files and rotary K-Flex files showed a significant reduction in postoperative pain compared to hand files.
The present study showed a significant reduction in bacterial count, working time, quality of obturation, and postoperative pain with rotary files.

儿童旋转锉系统的引入是儿童牙髓病学领域的一次革命。这些锉具性价比高，有助于在更短的预备时间内实现一致的根管充填。
本随机对照试验（RCT）旨在对乳牙生物力学预备中的旋转技术和手动技术进行比较评估，以确定它们在清洁和成形效果、工作时间、充填质量及术后疼痛方面的效果。
对75名年龄在5至9岁需要进行牙髓摘除术的儿童进行了一项随机临床试验研究。每颗牙齿被随机分配到三个治疗组之一：Kedo-S锉组、旋转K-Flex锉组和手动器械组。
观察到，与手动H/K锉相比，Kedo-S锉和旋转K-Flex锉在根管清洁和成形方面更有效。与旋转锉相比，手动锉的细菌计数更高。与手动锉（15.68分钟）相比，旋转锉的工作时间更短（3.88 - 5.04分钟）。旋转锉的空隙数量减少，Kedo-S锉在92%的病例中如此，旋转K-Flex锉在80%的病例中如此。旋转锉的根尖封闭和充填程度最大，92%的病例评级为C级。与手动锉相比，Kedo-S锉和旋转K-Flex锉术后疼痛明显减轻。
本研究表明，旋转锉在细菌计数、工作时间、充填质量和术后疼痛方面有显著降低。
