ABSTRACT
Abstract Aim:
To evaluate canal transportation and centering ability of Protaper and WaveOne systems in curved root canals by cone-beam computed tomography.Methods:
Twenty human molars were randomly divided into two groups according to the system used Group GP (ProTaper Universal(r)) and group GW (WaveOne(tm)). CT scans were performed before and after the chemo-mechanical preparation on three points 2 mm, 3 mm and 4 mm from the tooth apex. The cuttings in dentin were measured and results were statistically analyzed.Results:
In GP, there was higher percentage in transport at 2 mm and 4 mm toward the mesial wall of the tooth root compared to GW (p<0.05). There was no difference between the systems regarding their centering ability.Conclusions:
None of the systems was able to touch all the dentin walls and stay centered during the chemical-mechanical preparation.Key words
