Pulpectomy has gained popularity in the pediatric dental practice for preserving the primary teeth in its position until exfoliation. There has been a paradigm shift from using manual instrumentation to rotary instrumentation for canal preparation in primary teeth. While studies show that there is a reduction in the instrumentation time with the use of rotary instruments which in turn influences the behavior of the child, its direct effect on the behavior of the children has not been evaluated.
To compare the behavior of the children during manual and rotary instrumentation for pulpectomy in the primary molars.
A single-blinded randomized clinical trial was conducted in 88 children in any one of the mandibular primary molars indicated for pulpectomy. The canal preparation was done using manual K files and rotary ProTaper (44 children in each group). The influence of these instrumentation techniques on the children was assessed with three different scales- Frankl Behavior Rating Scale; Venham Interval Rating Scale; Wong Baker FACES Pain Scale for evaluating the behavior, anxiety, and the pain experienced by the children, respectively during canal preparation.
A total of 88 participants, comprising 50 females and 38 males, participated in the study. An equal distribution of the participants with respect to age ( = 0.064), gender ( = 0.389), and teeth ( = 0.877) was observed between the groups. More cooperative behavior ( < 0.001); lesser anxiety levels ( < 0.001); lower intensity of pain ( < 0.001) were recorded in the children instrumented using Rotary files.
The present study concludes that it is preferable to use rotary instrumentation for primary canal preparation in pediatric practice as it has a more positive influence on the behavior of the children, which eventually determines the success of the treatment.
With rise in the use of rotary files for pulpectomy in primary teeth, the present paper demonstrates the influence of rotary instrumentation technique for canal preparation during pulpectomy on the behavior of the children in a dental chair. This paper throws light for the pedodontists to effectively perform pulpectomy in children with ease without leaving a psychological impact on the children.

牙髓摘除术在儿童牙科实践中越来越受欢迎，用于将乳牙保留在原位直至脱落。在乳牙根管预备中，从使用手动器械到旋转器械已经发生了范式转变。虽然研究表明，使用旋转器械可减少器械操作时间，进而影响儿童的行为，但尚未评估其对儿童行为的直接影响。
比较儿童在乳牙牙髓摘除术的手动和旋转器械操作过程中的行为表现。
对88名需要进行牙髓摘除术的下颌乳牙中的任意一颗进行单盲随机临床试验。使用手动K锉和旋转ProTaper进行根管预备（每组44名儿童）。分别使用三种不同的量表评估这些器械操作技术对儿童的影响——弗兰克行为评定量表；维纳姆间隔评定量表；面部表情疼痛量表，以分别评估儿童在根管预备过程中的行为、焦虑和疼痛感受。
共有88名参与者，包括50名女性和38名男性参与了该研究。两组之间在年龄（P = 0.064）、性别（P = 0.389）和牙齿（P = 0.877）方面的参与者分布均衡。使用旋转锉进行器械操作的儿童表现出更合作的行为（P < 0.001）；焦虑水平更低（P < 0.001）；疼痛强度更低（P < 0.001）。
本研究得出结论，在儿童牙科实践中，乳牙根管预备使用旋转器械操作更佳，因为它对儿童行为有更积极的影响，最终决定治疗的成功与否。
随着旋转锉在乳牙牙髓摘除术中的使用增加，本文展示了牙髓摘除术中根管预备的旋转器械操作技术对牙科椅上儿童行为的影响。本文为儿童牙医轻松有效地为儿童进行牙髓摘除术提供了思路，且不会对儿童造成心理影响。
