Tooth decay detector
Tooth decay could soon be detected without resorting to potentially harmful x-rays by using a novel electrical technique developed by dental researchers at the University of Dundee in an unusual partnership with textile experts at another Scottish university, Heriot Watt.
Known as ACIST (alternating current impedance spectroscopy technique), the device has been developed to measure the electrical resistance of teeth, detecting decay in the early stages when preventative treatment is still possible.
By applying an electrically conductive strip to the tooth and passing a small current through it, dentists can use the amount of resistance to the charge as a gauge of whether there is decay.
