Abstract
Introduction: A secure reproducible glide path is an essential prerequisite for introducing “Rotary nickel titanium” files into a canal. With the rise of engine driven instruments over the past decade, the creation of a Glide path “GP” using “Rotary nickel titanium” files would seem to be an easier and simpler approach whenever possible.
Aim of the study: To Examine and note the similarities or differences in cyclic fatigue “CF” resistance between two continuous rotation and two reciprocating GP “Rotary nickel titanium” files in artificial S-shaped canals. Materials and methods: Four different GP files were used on forty artificial resin blocks. The files used were “Proglider” and One G files for continuous rotation files and “WaveOne Gold Glider” and “R-pilot” for reciprocating files. CF resistance was assessed through recording the time taken for each file to fracture inside the S-shaped canals in addition to the length of each fractured fragment. An independent sample t-test was used to analyze the data. Results: The number of cycles to fracture in the Reciprocating GP “Rotary NiTi” files were found to be statistically significantly higher when compared to Continuous rotation GP “Rotary NiTi” files (P value ≤0.05). Conclusion: Reciprocating GP files promoted higher CF resistance than continuous rotation GP files.
