Aim: to evaluate the use of CBCT to assess the effects of various access cavity designs on the canal transportation of root canals in human premolars that have been produced with a single rotary and reciprocating file system. Materials and Methods: Six groups of sixty mature single-canal premolars were randomly selected. In Group 1, traditional access cavity design (TECs) were performed and canals were prepared with HyFles/EDM file (TAC/ HYflex), Group 2: Conservative access cavity design with Hyflex EDM (CAC/Hyflex), Group 3: Traditional access cavity design with WaveOne Gold (TAC/WOG), Group 4: Conservative access cavity design with WaveOne Gold (CAC/ WOG), Group 5: Traditional access cavity design with TruNatomy (TAC/ TRN) and Group 6: Conservative access cavity design with TruNatomy (CAC/ TRN). To calculate root canal transportation, CBCT imaging was done both before and after root canal preparation. Results: The TRN file had the lowest canal transportation, whereas the WOG group had the greatest value. The difference between the WOG and TRN and Hyflex groups was statistically significant (P≤ 0.0001). Hyflex and TRN did not significantly differ from one another (p=0.674). It was found that, CAC recorded a considerably higher canal transportation than TAC regardless of the instrumentation file systems used, with significant differences at the apical and middle thirds and a non-significant value (p=0.373) at the coronal third. Keywords: Conservative access cavities, Canal transportation, Hyflex EDM, Traditional endodontic cavities , TruNatomy, WaveOne Gold.
