This study assesses the instrumentation time and quality of obturation of three pediatric rotary endodontic systems-GT nickel-titanium (NiTi) (Prime Pedo), controlled memory (CM) NiTi (Pro-AF-Baby Gold) and NiTi-titanium oxide (NiTi-TiO) (Kedo SG Blue).
A total of 60 children aged 4-8 were chosen at random for the study based on inclusion criteria that required pulpectomy in any of the primary molars and were separated into three groups of 20 samples, each based on the file system employed. The instrumentation time during the preparation of the canal is recorded using a stopwatch. An expert dentist was blinded to the instrumentation type and showed the periapical radiograph, which he or she graded depending on the quality of the obturation by categorizing it as underfill, optimal fill, or overfill. The observations were then recorded, tabulated, and statistically analyzed for the results.
The least amount of instrumentation time was needed for NiTi-TiO (group III) files, followed by NiTi-CM (group II) and NiTi-GT (group I). NiTi-TiO (group III) has the most optimally filled and least underfilled obturations among the three rotary endodontic systems mentioned. Also, NiTi-TiO (group III) and NiTi-CM (group II) have the least similar overfilled obturations when compared with NiTi-GT (Group I).
We conclude that NiTi-TiO needed the least amount of instrumentation time and generated the maximum optimally filled obturations based on our observations.
Pediatric rotary endodontic systems are more convenient to use and reduce chairside time; thus, their use in children with behavior control issues might be more suitable.

本研究评估三种儿童旋转根管治疗系统——GT镍钛（NiTi）（Prime Pedo）、可控记忆（CM）NiTi（Pro-AF-Baby Gold）和镍钛-氧化钛（NiTi-TiO）（Kedo SG Blue）的预备时间和充填质量。
根据纳入标准，随机选取60名4至8岁的儿童参与本研究，纳入标准要求对任何一颗乳磨牙进行牙髓摘除术，并根据所使用的锉系统将其分为三组，每组20个样本。使用秒表记录根管预备过程中的操作时间。一位专业牙医在不知道器械类型的情况下查看根尖片，并根据充填质量将其分为欠填、恰填或超填进行分级。然后记录观察结果，制成表格，并对结果进行统计分析。
NiTi-TiO（III组）锉所需的预备时间最少，其次是NiTi-CM（II组）和NiTi-GT（I组）。在上述三种旋转根管治疗系统中，NiTi-TiO（III组）的恰填率最高，欠填率最低。此外，与NiTi-GT（I组）相比，NiTi-TiO（III组）和NiTi-CM（II组）的超填率最相近。
根据我们的观察，我们得出结论，NiTi-TiO所需的预备时间最少，并且产生的恰填率最高。
儿童旋转根管治疗系统使用起来更方便，减少了椅旁操作时间；因此，对于有行为控制问题的儿童来说，使用该系统可能更合适。
