This study aimed to evaluate the efficacy of intracanal reduction using pediatric rotary (EndoArt Pedo Kit Blue, EasyInSmile X-Baby and Denco Kids), rotary (ProTaper Next) and reciprocating (WaveOne Gold) file systems through microbiological analyses in primary molars. Seventy-five mandibular primary second molars were selected and divided into five instrumentation groups and a negative control group. After incubation, five roots were used to confirm biofilm formation on the root canals. Before and after instrumentation, bacterial samples were collected. The bacterial load reduction was statistically analyzed by using Kruskall-Wallis and Dunn post hoc tests at a significance level of 0.05. Denco Kids and EndoArt Pedo Kit Blue promoted higher bacterial reduction than EasyInSmile X-Baby systems. There was no difference in bacterial reduction between ProTaper Next rotary file systems and other groups. Among the single-file techniques, instrumentation with the Denco Kids rotary system showed a more significant bacterial load reduction than WaveOne Gold ( < 0.05). All systems used in the study reduced bacterial counts from root canals in primary teeth. Further studies are required to generate more information about the use of pediatric rotary file systems in clinics.
本研究旨在通过微生物分析评估儿童旋转（EndoArt Pedo Kit Blue、EasyInSmile X-Baby 和 Denco Kids）、旋转（ProTaper Next）和往复（WaveOne Gold）锉系统在乳磨牙根管内减少的疗效。选择 75 颗下颌第二乳磨牙，分为 5 个器械组和一个阴性对照组。孵育后，用 5 个根来确认根管内生物膜的形成。在器械预备前后，采集细菌样本。使用 Kruskal-Wallis 和 Dunn 事后检验，以 0.05 的显著性水平对细菌减少量进行统计学分析。Denco Kids 和 EndoArt Pedo Kit Blue 比 EasyInSmile X-Baby 系统促进了更高的细菌减少。ProTaper Next 旋转锉系统与其他组之间的细菌减少量无差异。在单锉技术中，与 WaveOne Gold 相比，Denco Kids 旋转锉系统的器械使用显示出更显著的细菌负荷减少（<0.05）。研究中使用的所有系统均减少了乳牙根管中的细菌计数。需要进一步的研究来提供更多关于在临床中使用儿童旋转锉系统的信息。
