Diagnodent® scans teeth for hidden decay, often detecting cavities long before they can be seen by the naked eye. When we catch a cavity early, a smaller filling can usually be placed and preserve more of your natural tooth.
The Diagnodent uses laser fluorescence to aid in the detection of caries within the tooth structure. As the incident laser light is dispersed into the site, carious tooth structure will exhibit fluorescence, proportionate to the degree of caries, resulting in elevated scale readings on the display. Clean healthy tooth structure exhibits little or no fluorescence and will result in very low scale readings on the display.
