Abstract: BACKGROUND: White spot lesions (WSLs) appear as white, opaque areas on the teeth and are caused by a demineralization of the enamel. OBJECTIVE: The purpose of this systematic review and meta-analysis was to determine whether casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) has beneficial effects on WSLs and provides remineralizing benefits that are superior to those of placebo or no treatment. METHODS: Following a thorough analysis of the literature across major online sources, 103 papers – 54 of which underwent in-depth evaluation – were found. We used inclusion and exclusion criteria to choose research articles that were appropriate for our review. RESULTS: 10 papers met this review’s requirements and were subsequently included. As compared to the controls, CPP-ACP demonstrated increased efficacy in treatment of WSLs in terms of remineralisation and other parameters which included microhardness tests and enamel surface roughness. The forest plots present the results of meta-analyses comparing the effect of CPP-ACP versus control/other agents on white spot lesions (WSLs). In terms of odds ratios (OR), CPP-ACP showed a small increase in the odds of WSLs compared to control/other agents. In-vitro studies showed no significant difference in relative risk (RR) between CPP-ACP and control/other agents. Randomized control trials indicated a small increase in the risk of WSLs with CPP-ACP treatment, but the overall effect was not statistically significant. CONCLUSION: There was evidence to support the use of CPP-ACP over other agents for WSL prevention or treatment, but further research is needed to confirm these findings.
