Clinical Trial Summary

this study aimed to assess the effect of the application of the low-viscosity Icon resin infiltrate on the color change of the diagnosed white spot enamel lesions (WSLs) over 3-, 6-, and 12-m follow-up periods. The ICDAS scoring system was used to visually diagnose WSLs in a total of 96 anterior teeth in 49 participants and the teeth were then were evaluated for their color change using a spectrophotometer. According to the manufacturer directions the Icon kit was applied to the WSLs-diagnosed teeth as follows: the WSLs were treated with 15% hydrofluoric acid (Icon-Etch) was applied to the lesions for 120 seconds then it was rinsed for 30 seconds. Next, the etched WSLs were treated with 99% ethanol (Icon-dry) and for 30 seconds. Then the Icon-Resin was applied and light cured for 40 seconds. The change of color was done after 3-, 6- and 12-month . The mean and standard deviation values were statistically analyzed with the repeated measure ANOVA test and the Paired sample t-test.


Clinical Trial Description

The early caries may not be noticeable till it appears as rough enamel surface that might has chalky-white or even dark spots of brown color with no cavities formed. These spots reported were referred to as the white spot enamel lesions, that can be visually diagnosed with the ICDAS scoring method (International Caries Detection and Assessment System) that was proposed for the assessment of caries including early enamel lesions that are not yet cavitated and appear after through dryness of the enamel surface. Remineralization of the white spots enamel lesion presents the first choice treatment option. Still it has some short-outcomes, such as the staining-ability and unreliable esthetic results. It was reported that the Icon resin infiltration to masking the white spot enamel lesion at the minute of its application without a detectable change of color up to a period of six months. The Icon resin infiltration technique depends on its low-viscosity that enables its penetration into enamel surface through capillary action, occluding the micro porosities created in the enamel as a result of the white enamel lesions development. So that, the progression of the lesion would be stopped. Therefore, this clinical study was conducted to assess the effectiveness of the application of the Icon resin infiltration on the change of the color change of the white spot enamel lesions at follow-up periods of 3-, 6-, and 12-months. ;
