Comparative Evaluation of Cutting Efficiency of Three File Systems-Kedo-SH Manual, Pedoflex Rotary, and Manual K File: An

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 ( With regards to cutting efficiency, there was a statistically noteworthy difference among groups A and C [ 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.
