Root canal cleaning is a key step in the endodontic treatment of the primary molars. An innovative generation of endodontic instruments has been devised with the aim of emerging better procedures. The objective of the study is to assess the preparation of time, the risk of lateral perforation, and the removal of dentin from Kedo-S and Mtwo rotary instruments on primary teeth.
This is an experimental study comparing the two groups.
A total of 50 extracted mandibular primary first molars are collected, divided randomly into two groups of 25 teeth each. Group I: Kedo-S Pediatric rotary file, Group II: Mtwo rotary file. Distal canal is standardized for evaluation and teeth are sectioned at the CEJ. The teeth were instrumented according to manufacturer's guideline. Both the groups are scanned before and after instrumentation of the canal using cone-beam computed tomography (CBCT) and values are evaluated.
Compared with Mtwo files, Kedo-S files need less instrumentation time and limited lateral perforation. No statistical differences were reported between the instrumentation of Kedo-S and Mtwo with regard to the amount of dentin removed.
In pediatric endodontics, Kedo-S pediatric rotary file can be considered an effective alternative to traditional rotary files because it requires less instrumentation time and preserves dentin thickness.

根管清理是乳牙牙髓治疗的关键步骤。为了出现更好的治疗程序，已经设计出了新一代的牙髓治疗器械。本研究的目的是评估Kedo-S和Mtwo旋转器械在乳牙上的预备时间、侧穿风险以及牙本质的去除情况。
这是一项比较两组的实验研究。
共收集50颗拔除的下颌第一乳磨牙，随机分为两组，每组25颗牙。第一组：Kedo-S儿童旋转锉，第二组：Mtwo旋转锉。对远中根管进行标准化评估，并在牙釉质牙骨质界处将牙齿切片。按照制造商的指南对牙齿进行预备。在根管预备前后，使用锥形束计算机断层扫描（CBCT）对两组牙齿进行扫描并评估数值。
与Mtwo锉相比，Kedo-S锉所需的预备时间更少，侧穿风险有限。在Kedo-S和Mtwo预备过程中，去除的牙本质量方面未报告有统计学差异。
在儿童牙髓病学中，Kedo-S儿童旋转锉可被认为是传统旋转锉的有效替代品，因为它所需的预备时间更少，并能保留牙本质厚度。
