The purpose of this study is to determine whether Fluoride varnish + calcium (Clinpro White Varnish) and polipeptide solution (Curodont Repair) are effective in the treatment of remineralization therapy. The investigators will diagnose their alone or in combination effects on white spot lesions. Aesthetics (tooth-colored), remineralization, microbiological effects will be evaluated separately. Spectrophotometer (Vita Easy Shade) , Quantitative Light Fluorescence (QLF), Diagnodent(Cavo Diagnodent) and culture methods in microbiology laboratories are used for aesthetic, remineralization and microbiological assessments. The measurements will be made baseline, 6 weeks, 3 months and 6 months later after the applications and recorded.
