Abstract：
UNASSIGNED: The aim of this in vitro study was to evaluate the effect of the resin infiltration technique and remineralization of induced enamel caries with fluoride solution on the color masking of white spot lesions and surface roughness.
UNASSIGNED: A total of 45 sound teeth were used in this study. All the teeth were sectioned along the long axes into two halves, lingual and buccal to get 90 specimens. All specimens were immersed in a demineralized solution for 7 days. The specimens were divided randomly into three equal groups (n = 30) according to the type of treatment; Group 1 (n = 30) was treated with fluoride varnish (Clinpro); Group 2 (n = 30) was treated by resin infiltration (Icon); and Group 3 (n = 30) was used as a control group with no treatment. The color and surface roughness were measured three times at baseline (T1), directly after induction of artificial white spot lesions (WSLs) (T2), and directly after application of the treatment options (T3). The colors were measured using a portable reflective spectrophotometer and the 3D surface roughness was measured using a Light Sectioning Vision System. Data were collected and statistically analyzed using T test and Mann-Whitney U test.
UNASSIGNED: Surface roughness was almost equal in the study groups with no statistically significant differences reported. Icon showed slightly higher color scores than that of ClinPro.
UNASSIGNED: The Icon produced favorable esthetic results compared to the fluoride therapy while no significant differences were reported regarding the surface roughness.

摘要：
■这项体外研究的目的是评估树脂渗透技术和氟化物溶液诱导的釉质龋齿再矿化对白斑病变和表面粗糙度的颜色掩蔽的影响。
■在这项研究中总共使用了45颗健齿。所有的牙齿都沿着长轴分成两半，舌部和颊部得到90个标本。将所有样品浸入去矿物质溶液中7天。根据治疗类型将标本随机分为三个相等的组(n=30)；第1组(n=30)用氟化物清漆(Clinpro)治疗；第2组(n=30)用树脂渗透(Icon)治疗；第3组(n=30)作为对照组，不进行治疗。颜色和表面粗糙度测量三次基线（T1），直接在诱导人工白斑病变（WSLs）（T2）后，并在应用治疗方案后直接（T3）。使用便携式反射分光光度计测量颜色,并且使用光切片视觉系统测量3D表面粗糙度。收集数据并使用T检验和Mann-WhitneyU检验进行统计分析。
■研究组的表面粗糙度几乎相等，没有统计学差异。图标显示出比ClinPro略高的颜色分数。
■与氟化物治疗相比，Icon产生了良好的美学结果，而关于表面粗糙度没有显着差异。
