Abstract: Objective To evaluate the color stability of resin infiltration after ultraviolet (UV) aging.Methods 60 intact premolars were selected from orthodontic extraction,which were placed in the artificial demineralization solution for 3 days to form initial artificial enamel caries.The teeth were divided into 3 groups randomly: control (CON),resin infiltration (RI) and fluoride treatment (FLU).Changes in color of test samples were determined before and after UV aging for 8,16 and 24 h using the CIE L* a* b* system by a colorimeter.Results After being treated with resin infiltration or fluoride treatment,the ΔE* of 3 groups was RI
