【摘要】：目的研究渗透树脂治疗对釉质白斑样病损颜色的影响。方法选择人磨牙60颗,树脂包埋,以牙尖方向作为观察面,每个样本打磨出2个釉质小平面,随机分为A、B点。60颗样本牙随机分为第1、2、3组,每组20颗,经人工龋脱矿液分别脱矿24、48、72 h;对各样本的A点进行渗透树脂处理,B点行0.1%氟化钠涂氟处理30 d,B点涂氟处理后再行渗透树脂处理。应用电子分光光度比色仪测量A、B点脱矿及处理前后的L*值。结果各组A、B点脱矿前L*值没有明显差异,脱矿后均明显增加;经渗透树脂处理后,各组A点的L*值均较脱矿后降低,第1、2组的L*值恢复到脱矿前水平,第3组L*值与第1、2组存在差异(P0.05);经涂氟处理后,各组B点的L*值变化不明显;涂氟再经渗透树脂处理后,B点L*值明显降低,但仍高于A点和脱矿前(P0.05)。结论渗透树脂能够有效改善釉质白斑样病损的颜色,即刻效果优于传统涂氟治疗;其治疗效果与釉质脱矿程度及龋损活动性有关。
[Abstract]:Objective to study the effect of osmotic resin therapy on the color of enamel white spot lesion. One hundred and sixty teeth were randomly divided into group 1 and group 2, with 20 teeth in each group. Artificial caries demineralized solution was demineralized for 24 ~ 48 ~ 72 hours, and the A point of each sample was treated with permeable resin for 30 days and then treated with fluorine at point B of 0.1% sodium fluoride for 30 days and then treated with permeable resin for 30 days. Aneb was measured by means of electronic spectrophotometric colorimetry. Results there was no significant difference in L * values before and after demineralization of Agna B point in each group. After demineralization, the L * value of A point in each group was lower than that after demineralization, and the L * value of group 1 and 2 returned to the level before demineralization, and there was a difference between group 3 and group 1 (P0.05), and after fluorination treatment, there was a significant difference between group 1 and group 1 (P < 0.05). The L* values of B spots in each group were not significantly changed, the L* values of B spots were significantly decreased after fluorosis was treated with permeable resin, but still higher than that of point A and P 0.05 before demineralization. Conclusion osmotic resin can effectively improve the color of enamel leukoplakia lesions. The immediate effect was superior to that of traditional fluorosis therapy, which was related to the degree of demineralization of enamel and the activity of caries.
