Dental cavities are caused by the acidity created by bacteria in plaque. Areas with high acidity are more prone to cavities. A recent Medgadget article discussed a new dental instrument that predicts where cavities are likely to occur by monitoring the acidity levels in the plaque. The device, dubbed the O-pH system, was developed by a team at University of Washington. It’s a dental probe that uses fluorescence to measure local acidity levels in and around the teeth.
