Abstract:
Objective: To evaluate shaping ability of nickel-titanium rotary instruments (Hero 642) in curved root canals. Methods:The computer assistant measure system of simulated root canal was used for quantitative analysis of root shape in eight simulated root canals during nickel-titanium rotary instruments (Hero 642) shaping process. Results:Nickel-titanium rotary instruments (Hero 642) could keep the curved angles in simulated canals very well. The cutting of Hero 642 in curved root canals was balanced and there was almost no transportation of canals central lines when the simulated canals were prepared to 0.02 taper 25~# and 30~# files. Conclusion:Nickel-titanium rotary instruments (Hero 642) has good shaping ability. In preparation of highly curved canals, the master apical file (MAF) may be Hero 642 0.02 taper 30# files.
