Caries Detection Methods Based on Changes in Optical Properties between Healthy and Carious Tissue

<table>Transillumination (TI) with Near-Infrared (NIR) light. experimental set-up of the TI system.  The tooth is illuminated with NIR light. Polarizers are used to experimentally block out the ambient light from saturating the detector, a Charge Couple Device (CCD).</table>
