초록
Microcomputed tomography (MCT) made it possible to investigate the morphology of root canals more accurate. The aim of this study was to compare the effects of four root canal shaping methods, the profile system, the ProTaper system, a combination of these, and stainless steel K-files, in the shaping of the mesial root canals of extracted human mandibular first molars, three-dimensionally using MCT. Eight extracted mandibular first molars were scannde using MTC before and after the root cannals were instrumented. Two specimens were prepared using the Profile system and another two specimens were prepared using MCT before and after the root cannals were instrumented. Two specimens were prepared using the Profile system and another two specimens were prepared using the ProTaper system according to manufactures recommendation.(omitted)
