Abstract

OBJECTIVES: The aim of this study was to investigate the capacity of an approved food additive with anticariogenic properties, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), when added to a processed, sugar-containing yogurt with added lactic-acid bacteria (probiotics), to prevent demineralization of enamel subsurface lesions in vitro. METHODS: Enamel subsurface demineralised lesions were created in thirty extracted human third molars. These were then exposed to artificial saliva (AS) with: 1) Danone yogurt alone; 2) Danone yogurt with 0.2 % w/w CPP-ACP; or 3) Danone yogurt with 0.5 % w/w CPP-ACP at 37 °C for two weeks. The yogurt/AS was replaced with fresh preparations each da..
