Abstract

Dental caries is one of the most prevailing oral diseases which can be healed if detected in early stages of formation. In this paper, we present a clinically and commercially viable thermophotonic imaging technology for detection of early enamel caries using an inexpensive long-wavelength infrared (LWIR) camera. The efficacy of the system is verified through theoretical simulations as well as experiments carried out on extracted teeth with natural and artificially-induced caries.
