    "goal": "Promote tooth remineralisation, reduce dentine hypersensitivity, inhibit caries and periodontal disease.",
    "problem_addressed": "Tooth demineralisation and sensitivity, especially in older individuals with reduced saliva flow, leading to cavities and gum recession.",
    "concept_summary": "A multicomponent oral care composition that combines a fluoride ion source, a calcium ion source, a phosphate ion source and stabilised chlorine dioxide. The ingredients act synergistically to provide antibacterial action, plaque removal and controlled release of calcium and phosphate, thereby facilitating the formation of fluorapatite and remineralising enamel.",
