DIAGNODENT PEN (KAVO)
The DIAGNOdent pen is a hand-held laser caries detection aid. It is a hand-held caries detection operates at a wavelength of 655 nm. At this specific wavelength, clean healthy tooth structure exhibits little or no fluorescence, resulting in very low scale readings on the display. However, carious tooth structure will exhibit fluorescence, proportionate to the degree of caries, resulting in elevated scale readings on the display of the DIAGNOdent.
