چکیده
|
This study was conducted to compare the cyclic fatigue (cf) resistance of one g, waveone gold glider, t-endo must tg, one g and vdw.rotate nickel-titanium (niti) glide path (gp) instruments in a simulated canal of 90° and a 3-mm radius canals at root canal temperature. methods: sixty niti files were used for the fatigue testing in stainless steel canals compatible with instrument sizes until fracture occurred (n=15): one g (#14/.03), waveone gold glider (#15/.02), t-endo must tg (#13/.04), vdw.rotate (#15/.04), the number of cycles to fracture (ncf) was calculated for each instrument, and the lengths of the detached fragments (ldf) were measured. data were statistically analyzed using the kruskal–wallis analysis and mann-whitney u tests at the %95 confidence level. results: there were significant differences in the cf resistance among the groups (p < 0.05), the highest to lowest ncf values of the files as follows: t-endo must tg, waveone gold glider, vdw.rotate, and one g. there was no significant difference within ldf among the groups p> 0.05). conclusion: the t-endo must tg files had the highest and the one g files had the lowest cf resistance in a simulated canal of 90°and 3-mm radius canals at root canal temperature.
