Additionally, preserving pericervical dentin may improve the long\u2010term prognosis of the tooth. The aim of this study was to compare the performance of two nickel\u2010titanium rotary systems, ProTaper Gold (PTG) (Dentsply Sirona, Ballaigues, Switzerland) and VDW.Rotate (VDWR) (VDW GmbH, Munich, Germany), in preparing mandibular incisors, focusing on pericervical dentin preservation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and Materials<\/jats:title>\n                    <jats:p>\n                      A total of 20 mandibular incisors with oval\u2010shaped root canals (Vertucci Type I) were selected, disinfected, and scanned by micro\u2010CT.
