Investigation of the effect of different irrigation solutions on the torque values of single file systems with reciprocating motion

Investigation of the effect of different irrigation solutions on the torque values of single file systems with reciprocating motion The aim of our study is to examine the torque values of single file systems that have reciprocating action Reciproc Blue (RB) (VDW, Germany, Germany), WaveOne Gold (WOG) (Dentsply Sirona, Ballaigues, Switzerland) and T-endo MUST (T-endo MUST; Dentac, Istanbul, Turkey) using sodium hypochlorite (NaOCl 5%), ethylene diamine tetra acetic acid (EDTA 17%) and saline (NaCl) solutions . Within the scope of this research; 90 human mandibular premolars teeth having single and oval cross-sectional canals were used. Apical foramen opening was controlled with #10 K types file and the length is determined then the teeth were randomly assigned to 9 groups (n=10). After apical enlargement was performed with the X-Smart IQ endodontic motor as recommendations of the manufacturers, a report was obtained showing the torque produced by each file during the motion. The teeth were diveded randomly into 9 groups of 10 teeth each. The torque value, the maximum torque value, and the time used for preparation were recorded for each file. One-way Anova analysis, Post Hoc test, Bonferroni test, and two-way Anova analysis were used to determine the statistical difference. The level of significance was set at p < 0.05. There was no statistically significant difference between the mean torque, maximum torque and time measurements of the samples based on the solutions. (p>0,05). T-endo MUST file system created high torque values compared to Reciproc Blue and WaveOne Gold file systems, and a statistically significant difference was found (p <0,05). Key words: Reciproc Blue, WaveOne Gold, T-endo MUST, torque, irrigation
