초록

The purpose of this study was to compare the root canal shaping ability of four nickel-titanium rotary instruments. Forty eight simulated curved root canals were instrumented in plastic with the Crown-down technique using the $ProTaper^{TM}$ , the ProFile, the $GT^{TM}$, and the Quantec. Canals were instrumented until apical canal were up to size 30 by one operator. Each instrument was used only once and instrumentation time was measured.(omitted)
