本研究的目的是评估三种实验性涂漆复合树脂的表面粗糙度和抗牙刷磨损性，这些树脂用于冠和桥树脂的遮光改性。与修复性复合材料或冠桥树脂相比，涂层树脂的填充体体积分数较低，因此具有较低的粘度。涂刷4万次后，涂漆树脂的最大表面粗糙度（Rmax）和最大磨损深度损失分别为2.45至4.07微米和8.63至13.67微米。Rmax值比冠状树脂和桥状树脂的Rmax值低37.7 ~ 67.5%。磨损深度比冠桥树脂低19.9 ~ 49.4%。这些结果表明，涂漆树脂有望具有足够的抗牙刷磨损性，因此可能适合临床使用。
The purpose of this study was to evaluate the surface roughness and resistance to toothbrush abrasion of three experimental paint-on composite resins developed for the shade modification of crown and bridge resins. The paint-on resins had less filler volume fraction than restorative composites or the crown and bridge resins and consequently were of low viscosity. The maximum surface roughness (Rmax) and the maximum depth loss by abrasion for the paint-on resins following 40,000 cycles of brushing ranged from 2.45 to 4.07 microm and 8.63 to 13.67 microm, respectively. Rmax values were 37.7-67.5% lower than that for the crown and bridge resin subjected to the same test. Wear depth was 19.9-49.4% lower than for the crown and bridge resin. These results suggest that the paint-on resins are expected to have adequate resistance to toothbrush abrasion and may therefore be suitable for clinical use.
