项目摘要

For the study of background color-shielding effects of Esthet・X^<TM> opaque resins and changes in color difference, the following results were mainly obtained. The whitening value for A2 was the second highest, followed by C1, B2, D3, A4 and C4, in this order. The blackening value for C4 was the highest, followed by A4, D3, B2, C1, A2 and WO, in this order.For the investigation of a method for estimating shielding effects on colored dentin, the results revealed a good correlation between TP value and L^* or b^* value according to differences in the thickness of resins of the same shade. This study also suggested that the thickness of the opaque resin shielding this coloring can be calculated based on the L^* value of the colored tooth.With respect to the thickness of opaque resin for colored teeth, A2-o resin used in this experiment, an excellent correlation was observed between the color differences which were obtained from non colored and colored floor dentin and L^* value of colored floor dentin. By determining the value of L^* by colorimetric analysis of the colored teeth, it was demonstrated that the thickness of the opaque resin that shields the background color could be predicted.For the study of shielding effect of experimentally produced opaque resin, shielding ability and color difference were calculated from each color of coronal composite itself and the color appeared from the composite which was laid on the experimental opaque resin to shield colored dentin based on L^*a^*b^* values with colorimeter. As a result, it was shown that good shielding effect and less influence on the color of the coronal composite, using the 2.00% apatite coating resin mixed in the low viscosity composite with 0.50mm in thick.

对Esthet·X^型不透明树脂的背景色屏蔽效果<TM>及色差变化的研究，主要得到以下结果。A2的增白值是第二高的，然后是C1、B2、D3、A4和C4，以此顺序。结果表明，在着色牙本质中，TP值与L^* 或B^* 值之间存在较好的相关性。本研究还提出，根据着色牙的L^* 值，可以计算出遮盖着色的不透明树脂的厚度，对于着色牙的不透明树脂厚度，本实验中使用的A2-o树脂，未着色和着色牙本质的色差与着色牙本质的L^* 值之间有很好的相关性。通过对着色牙齿的比色分析，确定L^* 值，证明了可以预测遮蔽背景颜色的不透明树脂的厚度。为了研究实验制备的不透明树脂的遮蔽效果，根据复合材料本身的颜色和复合材料铺在实验不透明树脂上的颜色，计算复合材料的屏蔽能力和色差根据色度计测得的L^*a^*B^* 值，对着色牙本质进行遮盖。结果表明，在0.50mm厚的低粘度复合材料中加入2.00%的磷灰石涂层树脂，具有良好的屏蔽效果，对复合材料的颜色影响较小。
