渗透树脂治疗对釉质白斑样病损颜色的影响
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、72h；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30d，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（P〈0.05）；经涂...

| Abstract_FL | Objective This study aimed to evaluate the effect of resin infiltration and fluoride solution on masking different demineralized white spot lesions by assessing color change. Methods Artificial white spot lesions were produced on 60 human molars. Each sample had at least two enamel surfaces opened (named A and B). The samples were randomly divided into groups 1, 2, and 3 according to their time of demineralization (24, 48, and 72 h). After demineralization, the A spot of each sample was treated by resin infiltration. The B spot was treated with 0.1% fluoride solution daily for 30 days. After the remineralization of the B spot, resin infiltration was used again on the B spot of each sample. Color assessment was performed by a spectrophotometer in five distinct stages: baseline, after the production of artificial caries, after resin infiltration of A spots, after 30 days of fluoride solution treatment of B spots, and after resin infiltration of remineralized B spots. Results Before demineralization, the L* values of spots A and B in all groups were not significantly different (P>0.05), whereas the L* values of spots A and B were significantly increased after demineralization. The L* values of A spots recovered signifi-cantly after treatment by resin infiltration (P<0.05), but only groups 1 and 2 reached the baseline. The L* values of B spots had no significant differences (P>0.05) after fluoride treatment compared with that after demineralization. After resin infil-tration on B spots, the L* values recovered but could not reach the baseline nor the level of A spots treated by resin infiltration only. Conclusion Resin infiltration is a more effective treatment for masking white spot lesions than traditional fluoride treatment. The effect of masking white spot lesions has certain relationships with the degree of demineralization and activity of the lesion. |
