INTRODUCTION
Pulpectomy has been a treatment of choice in all necrotic primary teeth. Advancing technology has brought the rotary system to reduce the manual dexterity and improve the quality of treatment for pulpectomy. Advancing technology in pediatric dentistry should be used for the better treatment protocol.
AIM
The aim of this study is to compare the obturation quality and instrumentation time after root canal instrumentation with rotary Kedo-S files, hand K-files, and H-files in primary molars.
MATERIALS AND METHODS
A randomized control trial where pulpectomy was performed on 75 primary molars equally distributed for instrumentation with K-file, H-files rotary Kedo-S files, respectively. The instrumentation time and obturation quality were noted.
RESULTS
Kedo-S files showed the least instrumentation time with better obturation quality as compared to other two groups (P < 0.001).
CONCLUSION
Pediatric rotary files Kedo-S has better obturation quality in minimum instrumentation time.
引言
牙髓摘除术一直是所有坏死乳牙的首选治疗方法。技术的进步带来了旋转系统，以减少手工操作的难度并提高牙髓摘除术的治疗质量。儿童牙科领域的技术进步应用于更好的治疗方案。
目的
本研究的目的是比较在乳牙磨牙中使用旋转Kedo-S锉、手动K锉和H锉进行根管预备后的充填质量和预备时间。
材料与方法
一项随机对照试验，对75颗乳牙磨牙进行牙髓摘除术，分别平均分配使用K锉、H锉和旋转Kedo-S锉进行预备。记录预备时间和充填质量。
结果
与其他两组相比，Kedo-S锉显示出最短的预备时间和更好的充填质量（P < 0.001）。
结论
儿童旋转锉Kedo-S在最短的预备时间内具有更好的充填质量。
