This study evaluated the separation of three different NiTi rotary instruments when used following a manual glide path achieved with stainless steel hand files. The study compares those results to two previous analyses that examined the same rotary files when used without first establishing a glide path.
- Breakage was significantly higher in association with canal curvature angles and the number of clinical uses.
- Breakage was significantly lower in this study, which utilized a glide path technique than the previous studies, which did not.
- The researchers recommended the use of stainless steel hand files to prepare a glide path prior to introducing rotary files.
