The Effect of Multiple Glass Bead Sterilization Cycles On Cyclic Fatigue of AF BLUE S one File

Abstract

Introduction: Sterilization represent an important and essential aspect, now days Most of the dentists
usually use the endodontic files for many times before they discard it, this could increase the need for
reliable and fast sterilization method, but without affecting the physical properties of the endodontic files.
Aim of the study: This study discusses an economic method of sterilization (glass bead) and its effect
on the fracture resistance of the AF Blue S one file (Fanta) with multiple reuses of the system. Method
and materials: A total of 75 AF BLUE S one NiTi Rotary files (FANTA) #25 size with 0.04 taper and 25
millimeter length, were used in this study, divided into three groups to test their cyclic fatigue resistance
after multiple sterilization cycles. Result: The results were statically analyzed using (SPSS) software, Anova
test showed a statically high significant differences between the groups. Conclusions: Within the limitation
of this study, it can be concluded that AF Blue S one file with 4 time glass bead sterilization cycle was the
most fatigue resistant compared to zero and two sterilization cycle.
