This paper aims to explore the detection threshold capabilities between light scattering and light absorption based dental caries detection methods. With this intention, the experiments will be conducted through examination of controlled artificially-induced early caries. It is anticipated that the molecular-contrast TPLI imaging technology outperforms OCT due to the more specificenThe copyright for the paper content remains with the author.Biomechanics and Biomedical EngineeringHeat TransferEarly dental cariesThermophotonic lock-in imagingSpectral-domain optical coherence tomographyArtificial demineralizationArticle
