Abstract:
Objective:To test the accuracy of Tri Auto ZX electronic apex locator(Morita,Japan)and JustyⅡ electronic canal length meter(TME-601,Yoshida Toei Engineering Company,Japan).Methods:26 root canals were tested in vitro.Electronic canal length(L_E) measurements were recorded with Tri Auto ZX and Justy Ⅱ respectively at the reading "APEX" and "0.5".Under stereoscope the deviation of L_E from the actual working length and degree of accuracy were determined.Results:The average deviation of the measurements obtained by Tri Auto ZX was significantly lower than that by JustyⅡat reading"0.5"(P
