The aim of this study was to evaluate effect of primer on toothbrush-dentifrice abrasion of composite-metal interface. Flat plate specimens were cast from the T-Alloy H (GC corp.) pure titanium metal. They were air-borne particle abraded with 70 μm alumina, and were either unprimed or conditioned with two types of primers. One primer is designed for noble metals as an Alloy Primer (Kuraray), and the other is the Estenia C&B Opaque Primer (Kuraray) material. An Estenia C&B OA3 (Kuraray) light-polymerized opaque resin and an Estema C&B E1 (Kuraray) indirect composite were bonded to the side of metal specimens. All specimens were stored in 37℃ distilled water for 2 weeks prior to testing. Toothbrush abrasion test was performed with 3.4 N vertical load and 20,000 reciprocal strokes, and used the Crest (P&G) dentifrice. Wear depth was determined by means of a scanning laser microscope (1LM21) and the results were analyzed by Mann-Whitney U test (P=0.05 level). Worn surfaces were observed by scanning electron microscope (S54300). The average wear depths in μm (n=8) with standard deviations in parentheses were 3.5 (0.5) for the primed group and 8.0 (1.4) for the unprimed group. Significant difference was found between the primed group and the unprimed group. Scanning electron microscopic was observed that the opaque resin was conspicuously detected characteristic worn pattern for unprimed specimens, whereas primed specimens did not show apparent worn pattern. It can be considered that application of the primer was useful as enhanced wear resistance of the bonded specimens at the composite-metal interface.

本研究的目的是评价底漆对牙刷-牙膏复合体-金属界面磨损的影响。平板试件由T合金H(GC公司)铸造而成。纯钛金属。它们是空气中的颗粒物，用70μm氧化铝研磨，并未进行底漆或用两种底漆进行处理。一种是为贵金属设计的合金底漆(Kuraray)，另一种是Estenia C&B不透明底漆(Kuraray)材料。将Estenia C&B OA3(Kuraray)光聚合不透明树脂和Estema C&B E1(Kuraray)间接复合材料粘结到金属试件的侧面。所有标本在37℃蒸馏水中保存2周后进行检测。牙刷磨损试验采用佳洁士牙膏，垂直载荷3.4N，往复行程20000次。采用激光扫描显微镜(1LM21)测定磨损量，并对结果进行Mann-Whitney U检验(P=0.05)。用扫描电子显微镜(S54300)对磨损表面进行了观察。μm(n=8)的平均磨损深度，圆括号中的标准差为3.5(0.5)和8.0(1.4)。引发组与非引发组之间差异有统计学意义。扫描电子显微镜观察到，未涂漆的不透明树脂有明显的磨损特征，而涂有底漆的试件没有明显的磨痕。可以认为，底漆的应用有助于提高粘结试件在复合材料-金属界面的耐磨性。
