Comparative evaluation of three access cavity preparation techniques on root canal instrumentation using micro-ct: an in vitro study

HIGHLIGHTS

• What: The aim of this study is to compare and evaluate the effects of three different access cavity apical transportation untouched surfaces and debris formation within the Material and methods Thirty extracted permanent mandibular first molars were selected and randomly assigned to three groups for this study: Group I received 3D-printed static guided cavity Group II underwent conservative access cavity and Group III was subjected to traditional access cavity (TAC) This study aims to fill this gap by evaluating and comparing these three access cavity techniques, focusing on their impact on apical transportation, untouched canal surfaces . . .
