    "inventor_name": "Dr Julian Holmes",
    "publication_year": 2007,
    "device_name": "Ozi-cure Dental Unit",
    "goal": "Eliminate dental caries and infection without drilling by using ozone gas to sterilise lesions and promote natural remineralisation.",
    "problem_addressed": "Traditional drill-and-fill dentistry removes healthy tooth tissue, causes pain, and requires repeated restorations.",
    "concept_summary": "A self-contained device generates ozone (O_3) from ambient air and delivers a short, controlled burst (10-60 s) to a carious lesion. The ozone oxidises and destroys bacteria and organic by-products, allowing saliva minerals to re-deposit and harden the tooth structure, thereby arresting decay without invasive removal of tissue.",

    "claimed_performance": "Treatment times of 10-60 seconds; effective sterilisation of carious lesions; reduction or elimination of drilling and filling; decreased treatment cost and patient anxiety.",
    "experimental_evidence": "In-vitro studies showed ozone reduces organic bio-molecules to a single acetate spike and CO_2; clinical trials (e.g., Holmes 2003, Baysan & Lynch 2001) reported successful arrest of occlusal caries, reduced treatment time, and lower sensitivity.",

        "A simple 60 second (average treatment time) treatment with a device that delivers a burst of ozone will destroy all the bacteria that caused the infection and the decay.",
        "The lower data shows the effect of 10 seconds of ozone; the profile now consists of a single main spike of acetate acid, and the other oxidation by-product is carbon dioxide.",
        "Studies from Europe ... have shown conclusively that the use of ozone in dental care is effective as a non-destructive method to manage decay and its destructive effects.",
        "The use of ozone has been shown to be the ideal way to manage anxiety of patients - young and old - and their carers.",
        "The correct operation of the Ozi-cure meets all current Health and Safety Regulations in all countries."
