Description
Summary:The purpose of this study was to comparatively evaluate the cutting efficiency of Pedoflex rotary, Kedo SH manual file, and manual K file systems used in root canal instrumentation while performing pulp therapy of deciduous teeth with a stereomicroscope. Forty-five extracted primary human root canals were chosen, and following the removal of pulp tissue, the canals were dyed with Indian ink and left to dry for 2 h. The samples were randomly divided into three groups, Group A: Kedo SH manual file system ( = 15), Group B: Pedoflex rotary file system ( = 15), and Group C: Manual K files ( = 15). After root canal instrumentation, all the root canals were cleared to make them transparent. The teeth after clearing were observed under stereomicroscope and scored according to the amount of dye present in the root canals. The data were tabulated and statistically analyzed with SPSS version 16 using Chi-square, Kruskal-Wallis, and Dunn's test ( ). With regards to cutting efficiency, there was a statistically noteworthy difference among groups A and C [ = 0.000] and groups B and C [ = 0.000]. Furthermore, groups A and B did not differ statistically significantly [ = 0.950]. Cutting efficacy of the Pedoflex rotary files was seen to be superior to that of Kedo SH and manual K files. Rotary files in deciduous teeth have various benefits over manual files, resulting in a noticeable reduction in working time, which has aided in maintaining patient participation by reducing the risk for fatigue. We conclude that NiTi rotary devices result in a superior cutting efficiency and, as a result, greater clinical success.
