Previous studies have established that carious lesions can be imaged with high contrast using near-IR wavelengths
coincident with high water absorption, namely 1450-nm, without the interference of stains. It has been
demonstrated that computer-controlled laser scanning systems utilizing IR lasers operating at high pulse repetition
rates can be used for serial imaging and selective removal of caries lesions. In this study, a point-to-point scanning
system was developed integrating a 1450-nm diode laser with the CO2 ablation laser. This approach is advantageous
since it does not require an expensive near-IR camera. In this pilot study, we demonstrate the feasibility of a
combined NIR and IR laser system for the selective removal of carious lesions.
