Abstract
The possibility to minimize enamel changes after tooth whitening would be a benefit to the patient. The aim of this study is to evaluate in vitro the addition of calcium glycerophosphate (CaGP) associated with 0.05% sodium fluoride and 35% hydrogen peroxide on the mechanical properties of enamel. Bovine enamel blocks (4 mm x 4 mm, n = 60) will be selected by initial surface hardness (SHI)…
