Resumo: | Aim: The purpose of this study was eval Aim: uate the occurrence of displacement on the apical and cervical thirds of artificial curved root canals with 30° of curvature, comparing the use of stainless steel hand and oscillatory files with nickel-titanium (NI-TI) hand, rotary and oscillatory files. Methods: Methods: Seventy artificial curved root Methods: canals were divided into 7 groups (n=10). All canals were prepared with sizes 15 to 40 instruments at the working length according to a crown-down technique. The amount of material removed in the curved portion of the simulated canals at 2 mm level outside and 11 mm inside was measured. Data were analyzed statistically by ANOVA and Tukey’s test (p<0.05). Results: Results: There was statistically significant Results: differences (p<0.05) at 2 mm level between NI-TI and steel stainless groups. At 11 mm, statistically significant differences (p<0.05) were observed between the groups that used rotary systems (5 and 6) and the remaining groups. Conclusions: Conclusions: The most centered preparations were those belonging to groups 5 and 6, at both levels. Root canal preparation with NI-TI files yielded better results than the stainless steel files especially when mechanically activated. |
