Spectrophotometric Evaluation of the Color Change of Artificial White Spot Lesions Treated with Three Different Commercially Available Remineralizing Agents: An In Vitro Study

Abstract

Introduction: This study evaluated the color changes induced by the treatment of intact and demineralized enamel surfaces with casein phosphopeptide-amorphous calcium fluoride phosphate (CPP-ACFP), casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and sodium fluoride. Material and Methods: Ninety-six sound teeth were collected. The samples were divided into "intact " and "demineralized " groups and then subjected to different treatments (CPP-ACFP, sodium fluoride, and CPP-ACP). After the treatment phase, the colors of samples were evaluated and compared with the pretreatment values. Results: Both demineralized and intact enamel samples underwent increased whiteness (L*) and reduced yellowness (b*) upon treatment with any of the agents (P < 0.001). More pronounced results were achieved with CPP-ACP. Conclusion: These treatments generally make the teeth look whiter, brighter, and clearer with a more natural appearance.
