By judicial selection of the laser wavelength and pulse duration for localized deposition and thermal confinement of the laser energy, medical and dental procedures are now feasible that would not be possible without this unique technology. There are several laser projects underway in my lab, including: hard tissue ablation mechanisms, selective removal of dental decay, thermal modification of dental hard tissues for the prevention of tooth decay, ablation of bone without thermal damage, soft tissue microsurgery, selective removal of dental composite, and the development of a novel CO2 multiple-use laser for hard tissue applications Optical or photonics based methods are playing an increasingly important role in medicine and dentistry by providing a means of minimally invasive diagnostics and imaging without the use of ionizing radiation. Projects include: the use of optical diagnostic tools such as optical coherence tomographic imaging, Raman scattering, IR and fluorescence imaging, and time-resolved photothermal radiometry. In order to use lasers and optical diagnostic tools safely and effectively it is important to characterize the optical properties of the tissue at the wavelengths of interest. Therefore, a major emphasis of my research has been on the accurate elucidation of those properties.
