Aims: The aim of this study is to compare the effectiveness smear layer removal in root canals between the conventional method and with a new mechanical device. Materials and Methods: Thirty extracted noncarious central incisors were used and divided equally into three groups. Group A (n = 10) was used the control group and was not biomechanically prepared or irrigated. Group B (n = 10) was cleaned and shaped using the conventional method with rotary instruments and by irrigation with 5.25% sodium hypochlorite (NaOCl) and saline. Group C (n = 10) was cleaned and shaped using a new mechanical device, a microendobrush along with the conventional method of irrigation with 5% NaOCl and saline. The teeth were split longitudinally into two halves and each half was divided into three equal parts to obtain a pair of coronal, middle and apical third segment. The specimens were mounted on clear acrylic and were evaluated under a profilometer microscope and scanning electron microscope to view the surface roughness. Statistical Analysis Used: Statistical analysis was done using One-way ANOVA post hoc Tukey test. Data were analyzed using Statistical Package for Social Sciences (SPSS), version 15.0 (SPSS Inc., Chicago, IL, USA) at significance level of P ≤ 0.05. Results: The results reveal that the newer method of irrigation with the microendobrush had better removal of the smear layer and other debris. The conventional method of irrigation shows better results than the control teeth but is not as efficient in removing smear layer compared to the newer method of irrigation. Conclusions: Based on the limitation of the study, the results reveal that the newer method of chemomechanical preparation is more effective at smear layer removal compared to the conventional method of chemomechanical preparation.
