OBJECTIVE We aimed here to evaluate the enlargement characteristics of two nickel-titanium rotary instrument systems that use two different preparation techniques, in simulated root canals under "operator-related variables" standardized conditions. MATERIALS AND METHODS A total of 40 simulated canals in resin blocks were divided into two groups as the(More)
