Abstract
This study aims to evaluate the effect of two metalloproteinases inhibitors of bond strength on dentin treated with Er:YAG laser, after degradation of the adhesive interface. Will be selected 40 third human molars (n = 10), which will have the crown portion cut in the horizontal direction in order to expose the dentin portion. The Er:YAG (260mJ/4Hz) will be applied to the dentin surface. …
