Four inexperienced clinicians and four endodontists shaped endo\u2010training blocks. Instruments were then subjected to cyclic fatigue and torsional tests under body temperature (37\u00b0C) condition (\n                    <jats:italic>n<\/jats:italic>\n                    =\u200910). The results were analysed using two\u2010way ANOVA test and Tukey HSD post hoc comparison at a significance level of 95%. OR used by inexperienced operators had a longer time to fracture compared to other groups (\n                    <jats:italic>p<\/jats:italic>\n                    &lt;\u20090.05).
