Assessment Of Fracture Resistance Of Maxillary First Molars After Root Canal Preparation Using Three Different Rotary Instruments (V-Taper, Protaper, Vortex Blue): Finite Element Analysis, Mehran Malakpour
Graduate Theses, Dissertations, and Problem Reports
Introduction: Long term success of endodontically treated teeth has been one of the most challenging aspects of the field of endodontics due to reduced fracture resistance of these teeth. Recently, researchers have heightened focus on conservative endodontics in order to sustain the tooth integrity, and reduce factors impacting the fracture resistance of endodontically treated teeth. As a result, rotary instrument manufacturers have developed files that have a minimal effect on original root canal anatomy. This study used Finite Element Analysis to investigate the dental biomechanical effect of rotary instrumentation during root canal therapy. The aim of this study is to …
