Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Oral and Dental Medicine - Department of Endodontics Summary: Introduction: This study compared the effect of 2 rotary nickel-titanium (NiTi) systems;WaveOne and ProTaper Universal on transportation, centering ability and volumetric changes of curved root canals. Methods: Thirty-four mesiobuccal root canals of mandibular molars (with angles of curvature ranging from 25{u00BA}- 35{u00BA}) were randomly dividedinto two groups (n=17); WO and PU groups. Canals were scanned using aCranex® 3Dx machine (Soredex, Tuusula, Finland) before and after preparation. Root canal transportation and centering ratio were evaluated at 3, 5, 8 mm from the apex. Amount of removed dentin was evaluated as well. The significance level was set at P {u2264} 0.05. Results: There was no significant difference between both systems in canal transportation, centering ability and volumetric changes. Conclusions:Both systems can effectively shape curved root canals, while preserving original canal curvature, and without excessive removal of dentin
