【摘要】：目的:比较在粘结托槽前后,树脂粘结剂和树脂改良玻璃离子粘结剂对牙面颜色的影响。方法:60颗新鲜离体前磨牙随机分为空白对照组、树脂粘结剂组和树脂改良玻璃离子组。在粘结托槽前、去托槽后和茶溶液着色后3个时间点,采用松风电脑比色仪测取牙面的L*、a*和b*值,计算牙面粘结托槽前后和着色处理前后的△E*值以评估牙面颜色的变化。结果:托槽粘结前后的△E*值,树脂粘结剂组(3.18±0.27)与玻璃离子组(3.17±0.64)显著高于对照组(1.89±0.16)(P0.05);着色处理前后对比的△E*值,树脂组和玻璃离子组发生临床可识别的颜色变化,△E*分别为(4.25±0.51)和(4.60±0.52),显著大于对照组(2.43±0.24)(P0.05);两种粘结剂之间在托槽粘结前后和着色处理前后均未见显著差异。结论:光固化复合树脂粘结系统与树脂加强型玻璃离子粘结系统均会影响牙面颜色,导致牙面易着色,但二者对牙面颜色影响无显著差异。
[Abstract]:Objective: to compare the effect of resin binder and resin modified glass ion binder on tooth color before and after bonding bracket. Methods: 60 fresh premolars were randomly divided into blank control group. Resin binder group and resin modified glass ionomer group. At 3 time points before bonding bracket, after removing bracket and after tea solution coloring, the values of Lna * and b * of tooth surface were measured by pine wind computer colorimetry. To evaluate the change of tooth color before and after the tooth surface bonding bracket and before and after coloring. Results: the value of E * before and after bracket bonding, The values of E * in resin binder group and glass ion group were significantly higher than those in control group (1.89 卤0.16), and the color changes in resin group and glass ion group were observed before and after coloration. E * was 4.25 卤0.51) and 4.60 卤0.52g respectively, which was significantly higher than that of the control group (2.43 卤0.24), and there was no significant difference between the two binders before and after bracket bonding and coloring. Conclusion: the photocurable composite resin bonding system and resin reinforced glass ionomer have no significant difference before and after coloring. The knot system affects the color of the tooth, But there was no significant difference in the color of tooth surface between the two groups.
