Sažetak
The aim of this study was to compare the accuracy of measurements of endometers ES-02 and ES-03 in dry canals and canals filled with sodium-hypochlorite and ethylenediaminetetraacetic acid (EDTA). For the experiment 31 one-rooted human extracted teeth were used. Working length of the root canal was determined visually using a #15 reamer as a control measurement. After that the teeth were mbedded in vial with freshly mixed alginate and the measurements were made with both devices. Two measurements were made in dry canal and canal filled with sodiumhypochlorite and EDTA for each device. The first value was the working length determined according to the sign -1,0 on the scale and display, respectively, which corresponds to the apical constriction. The second value was measured according to the sign 0,0 which corresponds to the external foramen. Results were analyzed statistically by MANOVA test, and as post-hoc test Student-t test was used. The measurements same as control were in 65% for ES-02 device, and 61%, for ES-03 device at point -1,0 in dry canal, although the difference was not statistically significant. Fluids in root canal statistically significant negatively influence on accuracy of measurements but that significance was 10 times greater at point of measurement -1,0 than at 0,0.
