Since quantitative light-induced fluorescence (QLF) was invented, it has been applied in detection and quantification of incipient caries. With the development of technology, the clinical application of QLF has been continuously developed. Also, it can detect and quantify the red fluorescence from plaque, which is thought related to periodontal diseases and the cariogenic ability of plaque. This article reviewed the most recent findings about the clinical application of QLF in caries and periodontal diseases.

Key words: quantitative light-induced fluorescence, dental plaque, caries, caries risk, periodontal diseases
