The canals were prepared by step-down technique. After preparation, the canals were received ultrasonic irrigation and split longitudinally. Debris scores were calculated after photographing with a digital camera. The number of visible open dentinal tubules were evaluated by SEM. Results: At middle third of the canals, when irrigated with 5 g/L NaOCl, the debris score in group Odontoson-M was significantly lower than that in other groups(P
