Why is it alright to leave the primer and not rinse it?
The acidic monomer of MDP is neutralized as it decalcifies the tooth structure. At the same time, the monomer penetrates the tooth and bonds chemically and physically. You do not need to rinse the primer, since it polymerizes after light curing.
