本研究的目的是评价磷酸钙沉淀法（CPP）和草酸钾处理在不同表面形态牙本质盘上的封堵能力。扫描电镜观察其闭塞能力。无论牙本质小管的直径如何，CPP方法对牙本质表面的牙本质小管具有一致的闭塞能力，并且CPP方法在牙本质小管中形成的沉淀深度没有显著差异。相反，草酸钾治疗的咬合能力随着牙本质小管直径的增加而降低。而草酸钾处理对牙本质表面脱矿的影响更明显。由于CPP方法显示出与牙本质小管直径无关的一致的闭塞能力，因此建议CPP方法将是治疗牙本质过敏的有效手段。
The aim of this study was to evaluate the occluding ability of calcium phosphate precipitation (CPP) method and potassium oxalate treatment when each method was applied to dentin disks with different Surface morphology. Occluding ability was observed by scanning electron microscopy. Irrespective of the diameter of the dentinal tubules, the CPP method showed a consistent occluding ability for dentinal tubules at the dentin surface, and that the depths of the precipitate formed in the dentinal tubules by CPP method were not significantly different. In contrast, the occluding ability of potassium oxalate treatment was reduced with increasing diameter of the dentinal tubules. However, the reduction of the occluding ability of potassium oxalate treatment was more markedly affected by the demineralization of dentin surface. Since the CPP method showed a consistent occluding ability irrespective of the diameter of the dentinal tubules, it is suggested that the CPP method would be a useful means for treating dentin hypersensitivity.
