title: Enamel opacities removal using two different acids: an in vivo comparison.
abstract: Computerized analysis assessed quantitatively the efficacy of microabrasion using 37% phosphoric and 18% hydrochloric acids with pumice on removal of enamel opacities. Baseline and after one month photos were taken and analyzed by Paint Shop Pro 7 software and Image Pro Express 4.0. Nonparametric tests were used. Results depicted significant differences immediately versus one month post treatment for both acids. It was concluded that both acids can be used, and as time passes enamel color improvement occurs.
