We examined shear bond strengths (SBSs) of various tooth-coating-materials including the experimental materials to dentin and demineralization resistance of a fractured adhesive surface after the SBS testing. Three resin-type tooth-coating-materials (BC, PRG Barrier Coat; HC, Hybrid Coat II; and SF, Shield force plus) and two glass-ionomer-type tooth-coating-materials (CV, Clinpro XT Varnish; and FJ, Fuji VII) were selected. The experimental PRG Barrier Coat containing 0, 17, and 33 wt% S-PRG filler (BC0, BC17, and BC33, respectively) were developed. Each tooth-coating-material was applied to flattened dentin surfaces of extracted human teeth for SBS testing. After storing in water for 32 days with 4000 thermal cycling, the specimens were subjected to the SBS test. Specimens after SBS testing were subjected to a pH cycling test, and then, demineralization depths were measured using a polarized-light microscope. ANOVA and Tukey's HSD test were used for statistical analysis. The SBS value of FJ and CV was significantly lower than those of other materials except for BC (p < 0.01). The lesion depth of FJ was significantly shallower than those of other materials (p < 0.01); that of CV was significantly shallower than those of BC, HC, SF, and the control; and those of BC0 and BC17 were significantly shallower than that of the control (p < 0.05). The resin-type tooth-coating-materials demonstrated significantly higher SBS for dentin than the glass-ionomer-type tooth-coating-materials; however, they were inferior to the glass ionomer-type tooth-coating-materials in regards to the acid resistance of the fractured adhesion surface.
我们检测了包括实验材料在内的各种牙齿涂层材料与牙本质之间的剪切粘结强度（SBS），以及在进行SBS测试后断裂粘结面的抗脱矿能力。选择了三种树脂型牙齿涂层材料（BC，PRG Barrier Coat；HC，Hybrid Coat II；SF，Shield force plus）和两种玻璃离子型牙齿涂层材料（CV，Clinpro XT Varnish；FJ，Fuji VII）。开发了分别含有0、17和33 wt% S-PRG填料的实验性PRG Barrier Coat（分别为BC0、BC17和BC33）。将每种牙齿涂层材料应用于拔除的人牙的平整牙本质表面进行SBS测试。在4000次热循环下于水中储存32天后，对标本进行SBS测试。SBS测试后的标本进行pH循环测试，然后使用偏光显微镜测量脱矿深度。采用方差分析和Tukey's HSD检验进行统计分析。FJ和CV的SBS值显著低于除BC之外的其他材料（p < 0.01）。FJ的病变深度显著浅于其他材料（p < 0.01）；CV的病变深度显著浅于BC、HC、SF和对照组；BC0和BC17的病变深度显著浅于对照组（p < 0.05）。树脂型牙齿涂层材料对牙本质的SBS显著高于玻璃离子型牙齿涂层材料；然而，在断裂粘结面的耐酸性方面，它们不如玻璃离子型牙齿涂层材料。
