The Effect of Rotation Speed of XP-endo Shaper on Apically Extruded Debris During Endodontic Procedures: an In Vitro Study

The aim of this study was to evaluate the effect using a higher rotation speed with XP-endo Shaper (XPS) on apically extruded debris and operation time during endodontic treatment retreatment procedures. Sixty mesial roots mandibular first molar teeth were randomly assigned four groups (Initial groups: XPS used at 1000 or 3000rpm speeds Retreatment speeds). During initial procedures preweighed eppendorf tubes collect debris, recorded in seconds. quantified by subtracting preinstrumentation from postinstrumentation weight Eppendorf tubes. Data analysed two-way ANOVA significance level 0.05. In all groups, use had no statistically significant amount (p>0.05). significantly decreased instrumentation (p<0.05). summary, high did not have but time.
