Evaluation of Fluorescence Imaging with Reflectance Enhancement (FIRE) for Quantifying Enamel Demineralization In vitro.

Abstract:

OBJECTIVES:To assess the ability of fluorescence imaging with reflectance enhancement (FIRE) to quantify early enamel demineralization in vitro. METHODS:A total of 30 bovine enamel specimens were immersed in demineralizing solution to produce artificial caries. Specimens were examined by FIRE, quantitative light-induced fluorescence (QLF), and polarized light microscopy (PLM) at baseline and after 0.5, 1, 2, 4, 8, 24, 48 and 72 h of immersion. Fluorescence loss measured by FIRE and QLF was compared with lesion depth measurements by PLM. RESULTS:Over all time points, measurement of fluorescence loss by FIRE correlated well with the measurement of x0394;F by QLF and of x0394;Q by QLF. Both FIRE and QLF techniques showed significant correlation with PLM. CONCLUSION:FIRE technology may be useful for quantifying enamel demineralization in vitro.
