A Sydney dentist who potentially exposed almost 1000 patients to infection by failing to properly sterilise his equipment has allegedly treated at least one patient after he was investigated and barred from practising. NSW Health authorities last week contacted 930 patients who had invasive dental procedures performed by Dr Nicholas Southall at Cronulla Dental Surgery. Patients were urged to undergo testing for hepatitis b, hepatitis c and HIV after an investigation found evidence of poor cleaning and sterilisation of dental equipment in his practice.
