Abstract

The Quantitative Laser-induced Fluorescence (QLF) technique has been used for diagnosis of early caries in permanent teeth (PT). The objective of this study was to determine the caries quantification ability of QLF in deciduous teeth (DT). Sixty sound teeth, thirty DT and thirty PT, were used. All teeth were cleaned to remove debris and equally divided into three groups. Lesions were created in small windows (0.8×2.0 mm2) on buccal or labial surface for 48, 72, or 96 hr. Lesion images were made with a 488 nm argon laser (QLF I) and then with a 370±80 nm violet-blue light (QLF II). Both images were analyzed to determine the mean % change in fluorescence radiance (ΔF). A center section from the lesions was taken for analysis with microcardiography. The lesion depth and loss of mineral content (ΔZ) were determined. The correlations between ΔF and lesion depth as well as ΔZ in DT were 0.76 and 0.84 with QLF I, 0.81 and 0.88 with QLF II, respectively. In PT, correlations of 0.07 and 0.53 were found with QLF I, 0.15 and 0.62 with QLF II, respectively. It can be concluded the ability of QLF to quantify white-spots in DT is better than in PT.
