Non-destructive assessment of inhibition of demineralization in dental enamel irradiated by a = 9.3-µm CO2 laser at ablative irradiation intensities with PS-OCT
Background and Objective: Polarization sensitive optical coherence tomography (PS-OCT) has great promise for the non-destructive assessment of the efficacy of anti-caries agents such as fluoride and thermal laser treatments on enamel surfaces. The purpose of this study was to demonstrate that PS-OCT can be used to measure demineralization in craters/incisions prepared in enamel by a CO2 laser operating at the high irradiation intensities required for cavity preparations.
Materials and Methods
Incisions in bovine enamel surfaces were produced by a CO2 laser used with a water spray. The laser was operated at = 9.3 µm with a pulse duration of ...
