PURPOSE
To evaluate the surface roughness of two packable composites after finishing and polishing with six different systems.
MATERIALS AND METHODS
Solitaire and Alert composite samples were prepared and polished with Poli I and Poli II aluminum oxide pastes, Ultralap diamond paste, Enhance finishing points, Politip rubber polishers, fine and extra fine diamond burs, and 30-blade tungsten carbide burs according to the manufacturers' instructions. The polished surfaces were then evaluated with a profilometer and a scanning electron microscope.
RESULTS
Solitaire composite resin presented the smoothest surfaces when polished with Poli I and II aluminum oxide pastes, Ultralap diamond paste, Politip finishing points and 30-blade tungsten carbide burs. The smoothest surfaces for Alert composite were evident with the 30-blade tungsten carbide burs.
目的
评估两种可压实复合树脂在使用六种不同系统进行修整和抛光后的表面粗糙度。
材料与方法
制备Solitaire和Alert复合树脂样本，并根据制造商说明，分别使用Poli I和Poli II氧化铝糊剂、Ultralap金刚石糊剂、Enhance修整尖、Politip橡胶抛光器、细粒度和超细粒度金刚石车针以及30刃硬质合金车针进行抛光。然后使用轮廓仪和扫描电子显微镜对抛光后的表面进行评估。
结果
当使用Poli I和II氧化铝糊剂、Ultralap金刚石糊剂、Politip修整尖和30刃硬质合金车针进行抛光时，Solitaire复合树脂呈现出最光滑的表面。对于Alert复合树脂，使用30刃硬质合金车针时表面最光滑。
