Pediatric rotary systems have the advantage of improved canal centricity and conservative canal preparation with better obturation quality. Pro AF Baby Gold and Pedoflex files are two exclusive pediatric rotary file systems that were introduced in recent times.
The aim of the present study is to compare and evaluate the dentine thickness, centering ability, canal transportation, and instrumentation time of Pro AF Baby Gold and Pedoflex files using cone beam computed tomography (CBCT).
A total of 40 extracted human primary molar teeth with a minimum 7 mm root length were included in the study and randomly divided into two groups: group I, Pro AF Baby Gold; group II, Pedoflex files. Teeth were imaged preoperatively with CBCT, then root canal preparation was done in both groups with respective files, followed by postoperative CBCT imaging to evaluate the dentin thickness, centering ability, and canal transportation of both groups. Instrumentation time was noted using a stopwatch.
There is a statistically significant difference in the instrumentation time; Pedoflex took a shorter time when compared to Pro AF Baby Gold files. Regarding canal transportation, there was no significant difference between the two files, with Pedoflex showing a better value than the other files. Regarding centering ability, there was no significant difference between the two files, with Pro AF Baby Gold having a better value than the other files ( < 0.001).
From the findings of our present study, it was found that both systems were able to effectively shape curved root canals in terms of canal transportation and centering ability.

儿童旋转系统具有提高根管中心度以及进行保守的根管预备并获得更好充填质量的优势。Pro AF Baby Gold锉和Pedoflex锉是近期推出的两种专用儿童旋转锉系统。
本研究的目的是使用锥形束计算机断层扫描（CBCT）比较和评估Pro AF Baby Gold锉和Pedoflex锉的牙本质厚度、定心能力、根管偏移及预备时间。
本研究共纳入40颗拔除的人类乳磨牙，牙根长度至少为7mm，并随机分为两组：第一组，Pro AF Baby Gold锉；第二组，Pedoflex锉。术前用CBCT对牙齿进行成像，然后两组分别用相应的锉进行根管预备，随后进行术后CBCT成像，以评估两组的牙本质厚度、定心能力和根管偏移。使用秒表记录预备时间。
预备时间存在统计学显著差异；与Pro AF Baby Gold锉相比，Pedoflex锉用时更短。关于根管偏移，两种锉之间无显著差异，Pedoflex锉的值优于其他锉。关于定心能力，两种锉之间无显著差异，Pro AF Baby Gold锉的值优于其他锉（<0.001）。
从本研究的结果发现，两种系统在根管偏移和定心能力方面均能够有效地预备弯曲根管。
