【摘要】：目的研究具有增白效果的几种常见酸性物质对牙齿的作用,评估其对牙齿颜色及硬组织的影响程度。方法取新鲜健康牛牙制作釉质块,均保证5mm×3mm的釉质平面暴露。分为4组,每组90颗。A组使用白醋,B组使用苹果醋,C组使用30%过氧化氢溶液,D组使用去离子水(阴性对照),各组细分为30s、1min、3min3个小组,每组30颗。在模拟的口腔环境下进行漂白实验,按分组控制漂白时间。通过ShadeEye NCC牙齿比色仪、显微硬度仪以及SEM对漂白处理后的釉质块进行颜色、表面显微硬度和表面形态的检测。结果 A、B、C组3种试剂均有漂白效果,漂白前后颜色差异具有统计学意义(P0.05),漂白后1min及3min颜色改变为ABC组,差异有统计学意义(P0.05);对于牙齿表面显微硬度,食醋组降低最为明显,过氧化氢组次之,苹果醋对于硬度影响最小,各组间差异具有统计学意义(P0.05),A、B、C组各时点下显微硬度均低于D组(P0.05);白醋组牙齿硬组织表面形态改变最大,而过氧化氢对于牙齿表面形态影响最小。结论食醋、苹果醋和市售过氧化氢对牙齿均有一定程度的美白效果,但食醋对于牙齿硬度及表面形态的损害均较大。
[Abstract]:Objective to study the effects of several common acidic substances on teeth and evaluate their effects on tooth color and hard tissue. Methods fresh healthy bovine teeth were used to make enamel mass, and the enamel plane exposure of 5mm 脳 3mm was ensured. Each group was divided into 4 groups. Each group (90) was treated with white vinegar. Group B was treated with 30% hydrogen peroxide solution. Group D was given deionized water (negative control group). Each group was subdivided into 3 groups, 30 in each group. Bleaching experiments were carried out in simulated oral environment, and bleaching time was controlled by grouping. The color, surface microhardness and surface morphology of the bleached enamel were detected by ShadeEye NCC tooth colorimetry, microhardness tester and SEM. Results all the three reagents had bleaching effect, and the color difference before and after bleaching was statistically significant (P0.05). After bleaching, the color of 1min and 3min changed to ABC group, the difference was statistically significant (P0.05), and the microhardness of tooth surface was decreased most obviously in vinegar group. The effect of Apple Cider Vinegar on hardness was the least in hydrogen peroxide group (P0.05). The microhardness of group C was lower than that of group D at each time point (P0.05), and the change of surface morphology of hard tissue in white vinegar group was the greatest. Hydrogen peroxide had the least effect on tooth surface morphology. Conclusion vinegar, Apple Cider Vinegar and hydrogen peroxide can whiten teeth to a certain extent, but vinegar has great damage to tooth hardness and surface morphology.
