Development of white spot lesions (enamel demineralization) will be evaluated quantitatively during clear aligner orthodontic treatment compared to conventional fixed appliances using quantitative light induced fluorescence (QLF)
White spot lesion (WSL) may develop around fixed orthodontic appliances. With clear aligners, however, the issue is not controversial. WSL will be monitored in 2 groups of patients; one group using clear aligners and one group wearing fixed orthodontic appliances for 3 months. QLF images will be taken before treatment (T0) and 3 months after commencement of the treatment (T1). The results will be compared between the two groups
