Objectives : To evaluate the influence of the grain size coating and shaft angulation of ultrasonic and high-speed diamond burs on the dental cutting effectiveness. Materials and Methods : For the grain size evaluation, cavities were prepared on 40 incisors using high-speed (1092 and 1093F KG Sorensen® ) and ultrasonic tips (8.2142 and 6.2142-CVDentus® ). For the shaft angulation evaluation, cavities were prepared on 40 incisors using uniangulated (T1-CVDentus® ) and biangulated (T1-A CVDentus® ) ultrasonic tips. The cavities were bisected and examined at Χ50 magnification. The width and depth of cavities were measured by Leica QWin software. Kruskal-Wallis non-parametric test was used for analysis. Results : The grain size did not affect the cutting effectiveness, but the high-speed burs promoted deeper and wider cavities than the ultrasonic tips. The shaft angulation did not affect the cutting effectiveness; both the angulated and biangulated tips had greater cutting efficiency in dentin than in enamel. Conclusions : Ultrasonic tips promoted more conservative preparations and seemed promising for cavity preparation.
