This study evaluated the effectiveness of the (Diagnodent) fluorescence vs (Curing light) prism vs (Transilluminator) near infrared light beam for accuracy of white spot lesion detection in early caries diagnosis of proximal lesions. In this study thirty-two previously extracted primary and permanent caries free teeth were used. Demineralization method using Phosphoric Acid 37% at different time intervals. Demineralization detection by DIAGNOdent was recorded ranging from 0-78. Demineralization detection with Curing Light and Transilluminator was recorded as positive or negative. Radiographs before and after were obtained for mounted samples. 32 caries-free teeth were evaluated by radiographs, transilluminator, curing light, and Diagnodent. Both curing light and transillumination identified 20/32 (62%) demineralized teeth. The DIAGNOdent and radiograph failed to identify any teeth demineralization (0/32 for both methods). Significant differences were found in the mean etch time of successful classifications by curing light or transillumination compared to unsuccessful classifications (H (1,30)=31.50, P</em> < .001). Correctly classified teeth had a mean etch time of 107.25 (SD=30.11) compared to the mean etch time for incorrectly classified teeth of 61.25 (SD=26.72). Transillumination and curing light were able to detect demineralization whereas the DIAGNOdent and Radiographs did not. These findings suggest that transillumination and curing light may be reliable alternative diagnostic methods to digital bitewing radiography and DIAGNOdent for in vitro detection of early proximal demineralization. Differences in etch time should also be considered, as more etch time was related to better detection.
