Change In Resistance To Cyclic Fatigue Of Nickel-Titanium Files Exposed To Sodium Hypochlorite
Journal Title: Uluslararası Dis Hekimligi Bilimleri Dergisi - Year 2024, Vol 10, Issue 2
Abstract
Objective: This study aimed to assess the alterations in cyclic fatigue resistance of two types of nickel-titanium (NiTi) rotary files, both with and without CE certification, in their initial condition and after being subjected to 5% sodium hypochlorite (NaOCl) solutions for a duration of 5 minutes. Materials and Method: In this study, 32 new NiTi files of two types (V3-M size 25.04 and R-Shaper size 25.04), with and without a CE certificate, were used. The files were divided into groups of 16, with and without the CE certificate. These groups were further divided into two subgroups (n=8): new files and files exposed to 5% NaOCl for 5 minutes for sterilization. The cyclic fatigue resistance of the files was measured using a specially designed test device. The SPSS 22.0 Software Package (SPSS 22.0 Software Package Program, Inc., Chicago, IL, USA) was used to compare the cyclic fatigue resistance of the files. A significance level of p<0.05 was accepted. Results: When comparing the cyclic fatigue resistance of two different file groups before and after exposure, there was no significant difference between the pre-exposure and post-exposure values for the R-shaper file (p=0.74). However, for the V3-m type file, no statistically significant difference was found between the pre-exposure and post-exposure values (p<0.05). Conclusion: The cyclic fatigue resistance of NiTi rotary files with CE certification remained unaffected after exposure to 5% NaOCl, while the files without CE certification showed changes in their cyclic resistance. Therefore, we believe that the use of NiTi files with CE certification is of significant importance.
