摘要：The purpose of the present study is to evaluate the effectiveness of different irrigation techniques CNI, Ultrasound Irrigation, SonicMax on smear layer removal using Scanning electron microscopy (SEM). Materials and Methods: Eighty extracted single rooted teeth were instrumented with ProTaper rotary instruments. The roots were randomly divided into three experimental groups (n = 20): CNI, Ultrasound Irrigation, SonicMax and a control group, which was only irrigated with NaOCl. Next, the roots were sectioned in a buccolingual direction and the halves were examined by SEM. Smear layer was recorded in the cervical, middle and apical third of the roots. Data analysis was performed using the Kruskal–Wallis and Mann–Whitney U tests with a level of significance α = 0.05. Results:UI had the greatest amount of smear layer compared to other groups (P < 0.001) while control group the lowest in the apical third, while it was ultrasonic in the middle third. Conclusions: Sonicmax left the least amount of smear layer in all the three layers.
