The aims of this study are: 1) to formulate a hybrid coating and test its effect against enamel and dentin erosion and erosion-abrasion; 2) to modify the hybrid coating with the addition of fluoride and stannous, encapsulated or not, and thereafter test their effects against erosion and erosion-abrasion. The adhesion of the hybrid film to the dental substrate will be tested. Then, sodium …
