Research Abstract

Comparison of salivary mineral contents (Ca and phosphate) and enamel reaction suggested that remineralization in enamel was dependent on salivary Caamounts significantly. High resolution Quantitative Light-Induced Fluorescence system(QLF-D) was developed for assessment and it was found that intensities of red fluorescencein hidden caries correlated well with histological caries depth, and R/G ratio of redfluorescence images correlated with ISDAS scores.
