Journal ArticleDOI
The role of human salivary acidic proline-rich proteins in the formation of acquired dental pellicle in vivo and their fate after adsorption to the human enamel surface.
TL;DR: Little difference was seen in total proline-rich protein between pellicles formed in a 1 and a 24-h period, but there was a gradual degradation of the proteins.

Method and apparatus using infrared photothermal radiometry (PTR) and modulated laser luminescence (LUM) for diagnostics of defects in teeth
TL;DR: In this paper, a high-spatial-resolution dynamic diagnostic instrument which can provide simultaneous measurements of laser-induced frequency-domain infrared photothermal radiometric and alternating-current (ac) modulated luminescence signals from defects, demineralization, remineralisation and caries in teeth intraorally.
Journal ArticleDOI
Diagnosis of Pit and Fissure Caries Using Frequency-Domain Infrared Photothermal Radiometry and Modulated Laser Luminescence
TL;DR: PTR and LUM, as a combined technique, has the potential to be a reliable tool to diagnose early pit and fissure caries and could provide detailed information about deep lesions.
Journal ArticleDOI
Nonintrusive, noncontacting frequency-domain photothermal radiometry and luminescence depth profilometry of carious and artificial subsurface lesions in human teeth
TL;DR: PTR amplitude frequency scans over the surface of enamels of variable thickness exhibit strong thickness dependence, thus establishing depth profilometric sensitivity to subsurface interfaces such as the dentin/enamel junction, as well as a pronounced curvature in both the amplitude and phase signal channels.
Patent
Systems and methods for thermophotonic dynamic imaging
TL;DR: In this article, a system for improved thermophotonic imaging is provided in which both amplitude and phase image information is obtained with a high signal to noise ratio and depth-resolved capabilities.
