Images from 10 maxillary central incisors with WSL were collected by digital camera before and after treatment of resin infiltration. Images were imported into Image J. Two methods (gray scale and ratio of WSL) were performed to acquire data of gray scale and ratio of WSL of each crown before and after treatment of resin infiltration. Date of two methods was statistical analyzed respectively. The Student’s t-test showed significant difference between data from before and after treatment of resin infiltration.
