Patients with poor oral hygiene undergoing intervention are more likely to develop decalcification surrounding orthodontic brackets and bands, commonly known as white spot lesions (WSLs) (Behnan et al., 2010, Rodgers et al., 2010). Many times, even after the removal of fixed appliances and natural remineralization, these WSLs are still discernible. This in vitro research's goal was to use spectrophotometric analysis to examine how well two intervention modalities—resin infiltration (RI) and casein phosphopeptide amorphous calcium phosphate (CPP-ACP)—improved light reflectivity and, consequently, the formation of WSLs. Sixty extracted human third molars underwent partial demineralization to produce artificial WSLs, which were then randomly assigned to two treatment groups and an artificial saliva control group. The quantity of light (L*) reflected from each tooth specimen's surfaces was measured prior to and following treatment using a spectrophotometer (VITA Easyshade compact). The rise in L* following treatment revealed statistically significant reflectivity enhancements in all three cohorts. There were no statistically significant variations across the research groups, nevertheless. In the end, WSLs were successfully concealed by the control and both treatment strategies.
