PURPOSE: Human tooth enamel consists mostly of minerals, primarily hydroxyapatite, Ca10(PO4)6(OH)2, and thus synthetic hydroxyapatite can be used as a biomimetic oral care agent. This review describes the synthesis and characterization of hydroxyapatite from a chemist's perspective and provides an overview of its current use in oral care, with a focus on dentin hypersensitivity, caries, biofilm management, erosion, and enamel lesions. SOURCES: Reviews and original research papers published in English and German were included...

PURPOSE: Widely used in caries prevention, fluoridated varnish (FV) is also capable of remineralising carious lesions. However, the retention time of FV needed on enamel to ensure the maximum benefit is unclear. This study aimed to determine whether an increase in the retention time of 5% sodium fluoride (NaF) varnishes on enamel carious lesions enhances remineralisation. MATERIALS AND METHODS: Carious lesions were generated on bovine enamel slabs and treated with one of three 5% NaF commercial varnishes: Duraphat, Durashield or FlorOpal...

PURPOSE: To test the hypothesis that, in high caries-risk children, supervised toothbrushing (STB) reduces visible plaque levels and gingival bleeding to a greater extent than does unsupervised toothbrushing (USTB) in comparable children and in low caries-risk USTB children over 4 years. MATERIALS AND METHODS: High caries-risk schoolchildren, ages 6 to 7, were allocated to three oral healthcare protocols using a cluster-randomised design: 1. Ultra-Conservative Treatment (UCT): small cavities in primary molars were restored using ART, while medium and large cavities were left open and cleaned under daily supervised toothbrushing together with the remaining dentition (UCT/STB); 2...
