The development of decalcification around orthodontic brackets and bands, commonly called white spot lesions (WSLs), is often observed in patients with poor oral hygiene during treatment (Behnan et al., 2010, Rodgers et al., 2010). In many instances, these WSLs continue to be visible after the removal of fixed appliances and after natural remineralization. The purpose of this in vitro study was to compare the effectiveness of two treatment modalities, resin infiltration (RI) and Casein Phosphopeptide Amorphous Calcium Phosphate (CPP-ACP), at improving the light reflectivity and thus the appearance of WSLs using spectrophotometric analysis. Sixty extracted human third molars were partially demineralized to create artificial WSLs and randomly divided into a control (artificial saliva) and two treatment groups. A spectrophotometer (VITA EasyshadeÂ® compact) was used before and after treatment to quantify the amount of light (L*) reflected from the surfaces of each tooth specimen. All three groups showed statistically significant improvements in reflectivity, as indicated by the increase in L* after treatment. However, there were no statistically significant differences among the study groups. In conclusion, both treatment modalities and the control were effective at masking WSLs.
