In this study, Quantitative light-induced fluorescence (QLF) was used to analyze the progression of root caries and detect incipient lesions. Methods: An adult, aged 69 years old, who was informed about the aim of this study and had agreed to participate, was selected as the subject. The observation period was 2 years. The image of root caries was taken using QLF technique at 0 months and after 6, 18 and 24 months, and analyzed to assess the area and ΔF depth. A three-dimensional image was created from the volume of pixels. Results: The area of ΔF gradually increased with time, however the average ΔF showed same volume throughout the experimental period. In the three-dimensional image, the volume of the root caries lesion 2 years later was greater than that at the baseline. The root caries progressed in the direction of the apex and cement enamel junction after 2 years. Conclusions: The QLF technique may be useful for analysis of progression of root caries and early detection of incipient lesions. | ||
