Abstract
Considering the positive effects of high power lasers in preventing dental caries and the promising results regarding the reduction of enamel erosion, the purpose of this in vitro study is to evaluate the potential of a CO2 laser (9,3 µm) - associated or not with stannous fluoride or titanium tetrafluoride - in controlling erosion in dental enamel. Ninety slabs of human enamel will be sel…
