CO2-9.3 µm short-pulsed laser irradiation for reduction of enamel erosion (Conference Presentation)

The aim of this in vitro study was to verify the protective effect of short-pulsed CO2-laser irradiation against erosion of human enamel without and combined with TiF4 and AmF/NaF/SnCl2 applications, respectively. After 5 days, significantly reduced surface loss was observed after applying laser irradiation followed by applications of TiF4 or AmF/NaF/SnCl2 solution compared to Fluoride-application alone. After 10 days, a reduced tissue loss was observed in all groups treated with AmF/NaF/SnCl2 solution. This reduction was significantly higher when the application was combined with laser use (P<0.05). Conclusions: Short-pulsed CO2-9.3μm-laser irradiation followed by additional application of AmF/NaF/SnCl2 solution markedly reduces the progression of dental enamel erosion in-vitro.
