Patino PV, Biedma BM, Liebana CR, Cantatore G, Bahillo JG. The influence of a manual glide path on the separation rate of NiTi rotary instruments. J. Endod. 2005; 31:114–6.

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.

Conclusions:

  • 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.
