| Abstract: | IntroductionThe present study aimed to compare the torsional resistance of ProGlider (Dentsply Sirona, Ballaigues, Switzerland), Hyflex EDM (Coltene-Whaledent, Altstätten, Switzerland), and One G (Micro-Mega, Besancon, France) glide path instruments.MethodsFifteen ProGlider (16.02∼08), 15 Hyflex EDM (10.05), and 15 One G (14.03) instruments were collected and tested for torsional strength using a custom-designed testing device. Data were analyzed using 1-way analysis of variance and Tukey post hoc tests with 5% significance level. The tested specimens were examined under a scanning electron microscope.ResultsThere was no significant difference between Hyflex EDM and ProGlider regarding their torsional resistance values (P > .05). One G showed the lowest torsional resistance (P < .05). Hyflex EDM exhibited the highest angle of rotation values among the instruments (P < .05).ConclusionsHyflex EDM and ProGlider instruments had significantly higher torsional fatigue resistance than One G instruments, whereas Hyflex EDM showed the highest angle of rotation values. The differences in the torsional resistances might be associated with their different design features and manufacturing processes. |
