文题释义:
反色效应:在牙齿美白治疗完成后,颜色表现常常不是很稳定,牙齿颜色常会在短暂时间内,一般为美白后2-6周快速变回棕色,甚或更深色的褐色或黑褐色,测试其?E值快速下降,6周后颜色才会逐渐稳定下来,这种现象叫做牙齿美白后的反色效应。
 
背景:大多研究认为牙齿美白会造成牙釉质表面粗糙,易吸引外源性染色物质再次沾染而形成反色现象,在美白后尝试选用树脂表面处理剂使牙釉质表面光滑,以期降低反色效应。
目的:分析光固化树脂表面处理剂Adper Single Bond 2 Adhesive对冷光(氙激光)美白牙齿反色效应的影响。
方法:将24颗离体牙涂布体积分数35%的过氧化氢并氙激光照射美白,美白后,其中12颗颊侧涂布光固化树脂表面处理剂Adper Single Bond 2 Adhesive(实验组),另12颗不涂布光固化树脂表面处理剂(对照组),两组组内再分2亚组,分别浸泡于蒸馏水与茶水中进行老化实验,老化实验的第1,3,5,7,14,21,28,35,42天,观察样本色差变化;于美白前、美白后、涂布树脂表面处理后、老化实验的第28天观察样本表面微观结构。
结果与结论:①色差变化:实验组样本美白处理前后、涂布树脂表面处理前后及蒸馏水保存前后的色差值无差异(P > 0.05);浸泡于蒸馏水后,实验组与对照组色差值无差异;浸泡于茶水后,实验组第1-42天的色差值均小于对照组(P < 0.05);②扫描电镜观察:美白处理后的牙釉质表面存在破坏、空洞;涂布树脂表面处理剂后,实验组牙釉质光滑,少有空洞。浸泡于茶水后,实验组表面呈现渐层平滑面,有部分裂痕,片状染色层颜色分解不明显;对照组样本表面有孔洞较大的粗糙面,并清楚可见到茶水留下的斑驳染色层。浸泡于蒸馏水后,所有样本均只见少量块状染色层、孔洞,粗糙程度弱于浸泡于茶水的效果;③结果表明:涂布光固化树脂表面处理剂Adper Single Bond 2 Adhesive能够使冷光美白后的牙釉质表面变得平滑,降低染色物质黏附,起到降低美白后反色效应的作用。

Abstract:

BACKGROUND: Most studies suggest tooth whitening can create a coarse enamel surface which is likely to attract exogenous dyeing material and form the phenomenon of color relapse. After dental bleaching procedure, the use of resin surface treatment agent is expected to make the enamel surface smooth and alleviate tooth color relapse.
OBJECTIVE: To unravel the efficacy of Adper Single Bond 2 Adhesive on color relapse phenomenon after dental bleaching treatment by cold light (xenon laser) whitening.
METHODS: Twenty-four extracted teeth were collected and coated with 35% hydrogen peroxide followed by xenon laser whitening. The test group was made up of 12 samples coated with light-cured resin surface treatment agent and the left samples as control group were treated with no-coating agent after tooth whitening. Then the two groups were divided into two subgroups which were soaked in distilled water and tea for aging test respectively. The color differences (?E) which provided comparative values for statistical analysis was recorded at 1, 3, 5, 7, 14, 21, 28, 35 and 42 days after the aging test. The enamel surface microstructure of the samples was observed before and after bleaching, after resin agent coating, and 28 days after the aging test.
RESULTS AND CONCLUSION: (1) Results from color differences observation: there was no significant difference between samples soaked in distilled water before and after whitening treatment (P > 0.05). Similarly, there was no statistical difference between test group and control group soaked in distilled water (P > 0.05). However, after soaking in tea, the color differences in the test group at 1-42 days showed statistically significant differences from those in the control group (P < 0.05). (2) Results from scanning electron microscope observation: after the tooth whitening producers, the enamel surface was damaged in the presence of cavities. After coated with resin surface treatment agent, the enamel surface became smooth and had few cavities. After soaking in tea, gradient smooth surface, some crack, inconspicuous flake dyeing color layer decomposition could be seen in the test group while rough surface with big holes and mottled dyeing layer were clearly visible in the control group. All samples soaked in distilled water had only a small amount of block dyeing layer, holes, weaker roughness than those soaked in tea. To conclude, Adper Single Bond 2 Adhesive light-cured resin surface treatment agent could weaken color relapse phenomenon after tooth whitening, achieving a smooth enamel surface and reducing dyeing material adhesion.
