27 maxillary second bicuspid teeth with two canals and an isthmus were randomly assigned to 3 groups.Root-end preparations were made respectively using ultrasonic diamond tip Berutti and niti tip RE2,ultrasonic #40K file and slow-speed handpiece with No.2 round bur.Image processing and analysis system were used to measure the preoperation and postoperation parameters for further evaluating the difference between the two techniques.Results:
The cutting volume of ultrasonic instruments was less than slow-speed handpiece(P
