Sažetak
Aim: The aim of this study was to analyze the value of vertical forces and torque during rotary ProTaper® and ProFile® instrumentation and analyze the influence of the load on the vertical root fracture formation. Methods: The study included 40 extracted human teeth with single root. All teeth were prepared initially with hand K-files, to a diameter of 0.15 mm, and then were randomly divided into two groups of 20 each. In the group 1, canals were instrumented by rotary ProTaper®, in the group 2 by rotary ProFile® technique. Load was measured with specially designed device. The roots were cut horizontally in the cervical, middle and apical third. The samples were observed with a light microscope at a magnification 40x. Values of force and torque were expressed as median and range. Results were com- pared to the Mann-Whitney U-test. Statistically significant differences were defined as P < 0.05. Results: the vertical root fracture was not observed. The median force was significantly higher in the F2 instrument in relation to S2 instrument (P = 0.020). ProFile® OS3 instrument had a significantly greater strength compared to the OS2 (P < 0.001), 25/0.06 (P = 0.003) and 20/0.06 (P = 0.030). Significantly more torque was at F2 with respect to F1 (P = 0.003), S1 with respect to F1 (P = 0.004) during working length. Instrument OS3 had a significantly high- er torque compared to OS2 (P < 0.000) and 25/0.06 (P = 0.038). Conclusion: Shaping of the root canal with rotary ProTaper® and ProFile® instruments will not lead to fracture of the root if load is low, irrigating solu-tion is in the root canal and the canal is pre-shaped with hand K-Files.
