Abstract

This study aim at evaluating the effect of orthodontic treatment with fixed appliances on demineralization and White Spot Lesions (WSL) formation on enamel surface.
Sample consisting of 30 patients undergoing orthodontic treatment with fixed appliances, then demineralization and the number of WSL were observed at three time points:
T1: 6 weeks after appliance placement
T2: 6 months after appliance placement
T3: 12 months after appliance placement
To determine the Prevalence of White Spot Lesions, the study showed that the number of white spot lesions is getting bigger through time; men have more WSL than women, and no significant differences in prevalence of WSL between teeth
