Abstract: Objective　To observe the clinical effects and color stability of early caries lesions treated with resin infiltration. Methods　According to the inclusion/ exclusion criteria，and there were 10 patients （27 teeth） with early caries lesions were treated with resin infiltration. The results were classified into three levels：effective，partially effective，and unchanged. Standardized digital photographs of the patients were taken before treatment，and immediately，6 and 12 months after treatment，respectively. Pictures were analyzed using the Image J software. The area of white spot （W） and whole tooth labial surface （L） were measured，and then we analyzed the ratio of W/L. A nonparametric Wilcoxon rank test was used to do the statistical analysis，and P < 0.05 was considered statistically significant. Results　Among the 27 teeth，8 teeth （29.6%） were evaluated as effective，19 teeth （70.4%） were evaluated as partial effective，and no tooth was evaluated unchanged. The mean value of the W/L decreased from 28.71% to 4.34% after resin infiltration treatment （by nonparametric Wilcoxon rank test，P < 0.05）. After the 6 and 12 months follow-up，we didn’t observe the color change or the caries enlarged through the examination. Conclusion　The clinical effect of early caries lesions treated with resin infiltration is significant. During 12 months of follow-up，the clinical effect keeps stable and no further demineralization is observed. Therefore，resin infiltration can be used as a novel choice for minimally invasive treatment for early caries lesions.
