This study was planned to evaluate and compare the cleaning efficacy of three pediatric rotary files with the standard Protaper adult file system in primary teeth using cone-beam computed tomography (CBCT).
A total of 40 extracted deciduous second molars, with palatal/mesial roots having at least two-thirds of root length and an intact furcation area, were distributed randomly among four groups, with each group containing 10 teeth. Canal preparation of group I (Pro AF Baby Gold), group II (Kedo SG Blue), group III (Prime Pedo), and group IV (Protaper) was done. Pre- and postoperative CBCT images were taken. The volumetric changes of the root canals were assessed and subjected to statistical analysis using Statistical Package for the Social Sciences (SPSS) version 16 and R Studio 3.1.1. Volumetric changes within the groups were analyzed using paired -tests and between the groups using analysis of variance (ANOVA).
The comparison of mean volume difference between groups using ANOVA was statistically significant with = 4.467, = 0.002. A Tukey test revealed that group IV was statistically significant compared with groups I ( = 0.033) and III ( = 0.008) but was not statistically significant with group II ( = 0.170). There was no statistically significant difference in volumetric changes within the three pediatric rotary file systems.
Protaper removed more dentin than all the pediatric rotary files, but it was not statistically significant over Kedo SG Blue. Among the pediatric rotary files, Kedo SG Blue removed more dentin than Pro AF Baby Gold and Prime Pedo, but they were not statistically significant.

本研究旨在使用锥形束计算机断层扫描（CBCT）评估并比较三种儿童旋转锉与标准成人Protaper锉系统在乳牙根管预备中的清洁效果。
选取40颗拔除的乳磨牙，其腭侧/近中根的长度至少为根长的三分之二且根分叉区域完整，随机分为四组，每组10颗牙。对第I组（Pro AF Baby Gold）、第II组（Kedo SG Blue）、第III组（Prime Pedo）和第IV组（Protaper）进行根管预备。拍摄术前和术后的CBCT图像。评估根管的体积变化，并使用社会科学统计软件包（SPSS）16版和R Studio 3.1.1进行统计分析。组内体积变化采用配对t检验分析，组间采用方差分析（ANOVA）。
使用方差分析对组间平均体积差异进行比较，差异具有统计学意义（F = 4.467，P = 0.002）。Tukey检验显示，第IV组与第I组（P = 0.033）和第III组（P = 0.008）相比具有统计学意义，但与第II组相比无统计学意义（P = 0.170）。三种儿童旋转锉系统内的体积变化无统计学差异。
Protaper去除的牙本质比所有儿童旋转锉都多，但与Kedo SG Blue相比无统计学意义。在儿童旋转锉中，Kedo SG Blue去除的牙本质比Pro AF Baby Gold和Prime Pedo多，但无统计学意义。
