Abstract :The purpose of this investigation was to determine if changes in dental enamel with 20 micron depth incipient carious lesion could be detected by an ultrasonic system insert ignore into journalissuearticles values(US);. Natural insert ignore into journalissuearticles values(unground, unpolished); lesions were produced on human enamel by using a microbial caries model. Specimens with lesions were analyzed using Ultrasonic system insert ignore into journalissuearticles values(US); as test method, Quantitative-Light Induced Fluorescence insert ignore into journalissuearticles values(QLF); and Confocal Laser Scanning Microscopy insert ignore into journalissuearticles values(CLSM); as gold standards. It was found that both ultrasound and QLF could not detect these very early lesions insert ignore into journalissuearticles values(mean lesion depth: 18.89 μm); created in vitro in the microbial caries model.
