The Incidence Of Root Dentinal Micro-Cracks Caused By Reciprocating And Continuous Rotary Instrumentation, Stephen N. Schroeder
The Incidence Of Root Dentinal Micro-Cracks Caused By Reciprocating And Continuous Rotary Instrumentation, Stephen N. Schroeder
Theses and Dissertations
The aim of this study was to compare the incidence of root canal dentinal micro-cracks after canal instrumentation using reciprocating files (WaveOne Gold® and Twisted Adaptive®) and continuous rotation files (Edge Evolve® and EndoSequence®) in an ex-vivo benchtop study. This project used a novel methodology of finding dentinal defects using the “K-cube”, which allows evaluators to visualize sectioned root surfaces before instrumentation and after instrumentation. Mesial roots from 40 human mandibular first molars were divided into 4 groups of 10 for each file type. Root section pictures were taken with a Zeiss Discovery V20 stereomicroscope before and after canal instrumentation. …
