ABSTRACT
Objective:
To compare the quality of root-end preparation quantitatively between ultrasonic retrotips and traditional slow-speed handpiece.Methods:
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 40~#K 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<0.000 1).Conclusion:
Ultrasonic instrument is better in the root-end preparation than traditional slow-speed handpiece.
