Successful outcome of endodontic treatment depends on chemomechanical preparation of the tooth. However, during canal preparation, debris may extrude through the apical foramen causing postoperative complications. The aim of this study is to evaluate and compare the amount of apically extruded debris during the pulpectomy procedure in primary molar teeth using two different rotary files and hand files.
Distal roots of sixty extracted primary molars were divided into three groups: group A: Prime Pedo™ pediatric rotary files, group B: DXL-Pro Pedo™ pediatric rotary files, and group C: hand files. Myers and Montgomery experimental model was used. Preweighed Eppendorf tubes were used to collect apically extruded debris. The tubes were then placed in an incubator at 70°C for 5 days. The weight of the debris attained was determined. The data were analyzed using ANOVA and post hoc Bonferroni test.
Hand files produced more apical debris extrusion ( < 0.05). Prime Pedo™ pediatric rotary files produced the least debris ( < 0.05).
Prime Pedo™ and DXL-Pro Pedo™ pediatric rotary files extruded significantly lower amount of debris apically during pulpectomy as compared to hand files. Rotary files can be considered an alternative to hand files in pediatric endodontics.
根管治疗的成功结果取决于牙齿的化学机械预备。然而，在根管预备过程中，碎屑可能会通过根尖孔挤出，导致术后并发症。本研究的目的是评估和比较在乳牙牙髓摘除术中使用两种不同的旋转锉和手动锉时根尖挤出碎屑的量。
将60颗拔除的乳牙远中根分为三组：A组：Prime Pedo™儿童旋转锉；B组：DXL-Pro Pedo™儿童旋转锉；C组：手动锉。采用迈尔斯和蒙哥马利实验模型。使用预先称重的艾本德管收集根尖挤出的碎屑。然后将管子置于70°C的培养箱中5天。测定获得的碎屑重量。使用方差分析和事后邦费罗尼检验分析数据。
手动锉产生的根尖碎屑挤出量更多（<0.05）。Prime Pedo™儿童旋转锉产生的碎屑最少（<0.05）。
与手动锉相比，Prime Pedo™和DXL-Pro Pedo™儿童旋转锉在牙髓摘除术中根尖挤出的碎屑量明显更低。在儿童牙髓病学中，旋转锉可被视为手动锉的替代工具。
