To estimate the obturation quality and instrumentation time on comparing traditional hand files and two rotary file types during root canal instrumentation in deciduous molars.
Forty-five deciduous mandibular molars were taken and randomly allotted to three groups ( = 15). Group I: K-hand files, group II: ProTaper Gold rotary file, and group III: Kedo-SG Blue rotary files. Before and after root canal instrumentation, standardized digital radiography was taken and the instrumentation time was also noted. The recorded data were then subjected to statistical analysis utilizing SPSS Software version 22.0. To compare the instrumentation time and quality of obturation between the groups, a Chi-square test and ANOVA with the level of significance at 0.05 were employed.
There was no significant difference recorded with reference to the quality of obturation ( > 0.05). However, the difference was noticed to be statistically significant when the instrumentation time between the two rotary groups and the manual instrumentation groups was taken into account ( < 0.05). The rotary systems ProTaper Gold and Kedo-SG Blue exhibited a significantly less instrumentation time on comparing with that of the hand files.
Concerning the quality of obturation, all three file groups demonstrated almost a similar performance. However, there was a significant difference noticed in the instrumentation time with the use of manual instrumentation in comparison to rotary instrumentation in deciduous teeth.

在乳牙根管预备过程中，比较传统手动锉和两种旋转锉类型时，评估根管充填质量和预备时间。
选取45颗下颌乳磨牙，随机分为三组（每组n = 15）。第一组：K型手动锉；第二组：ProTaper Gold旋转锉；第三组：Kedo-SG Blue旋转锉。在根管预备前后，拍摄标准化数字X线片，并记录预备时间。然后使用SPSS 22.0软件对记录的数据进行统计分析。为比较各组之间的预备时间和充填质量，采用卡方检验和方差分析，显著性水平为0.05。
在充填质量方面未记录到显著差异（P>0.05）。然而，当考虑两个旋转锉组和手动预备组之间的预备时间时，差异具有统计学意义（P<0.05）。与手动锉相比，ProTaper Gold和Kedo-SG Blue旋转系统的预备时间明显更短。
关于充填质量，所有三组锉具表现出几乎相似的性能。然而，与乳牙的旋转预备相比，手动预备在预备时间上存在显著差异。
