How does AQUA PREP work?
AQUA PREP s main ingredient is HEMA in a water solution. When applied on the dentin surface, the water is not easily evaporated because of HEMA s ability to hold water molecules through hydrogen bonding. The preparation remains moist and ensures an adequately wet surface for bonding primers to completely penetrate dentin tubules. At the same time the HEMA solution is able to render a temporary desensitizing effect. For permanent desensitization, a subsequent layer of an acetone based adhesive must be applied to the HEMA-filled dentin and polymerized.
