RESUMEN
Objective: The goal of this systematic review was to evaluate the therapeutic efficacy of Casein Phosphopeptide Amorphous Calcium Phosphate (CPP-ACP) remineralizing potential to that of other remineralizing treatments and placebo in both naturally occurring and postorthodontic white spot lesions (WSL) in vivo. Materials and Methods: From 2005 to 2020, the literature search used electronic databases PubMed, Embase, Science Direct, and Google Scholar to find studies published solely in English and randomized controlled trials (RCTs) employing CPP-ACP as an intervention. All eligible studies were reviewed by two independent reviewers. Results: Excluding duplications, 72 articles were identified. Abstracts of 58 articles were reviewed independently, 19 articles were excluded, 36 full text articles were retrieved; finally selecting 14 studies. Conclusion: The CPP-ACP was found to have efficacious remineralizing potential on naturally occurring and postorthodontic WSL compared to placebo or other preventive measures. Further well-performed RCTs are needed to determine the therapeutic significance of remineralizing medicines, and long-term follow-ups are required.
