The aim of this study is to evaluate the effect of root canal preparation with XP-endo Shaper (XPS) used at high rotation speed on the fracture resistance of roots. Fifty mandibular canine teeth were decoronated to obtain a standard root length of 14 mm. They were randomly divided into 4 experimental groups and 1 control group (n=10): no preparation, preparation with XPS at 1000 rpm and 3000 rpm, preparation with XPS at 1000 rpm and 3000 rpm and filling with cold lateral compaction. Data were statistically analysed using 1-way analysis of variance (P=.05) The highest fracture resistance was observed in the control group, followed by the group with root canal preparation and root canal filling at 3000 rpm. The use of the XPS at 1000 rpm and 3000 rpm, or filling the root canals with epoxy resin-based sealers had no significant effect on the fracture resistances of the roots.
