Dental MaterialsA base material in dental restoration is primarily used to provide a seal against microleakage.

Dental Materials Etching of tooth surface with 37% phosphoric acid creates microporosities in the enamel and dentin. This is the main method of adhesion of composite resin to tooth surface.
After etching the surface energy of the enamel will increase. This will make it very sticky to any kind of contaminants. If salivary contamination will occur, the salivary proteins will precipitate in the microporosities. This will prevent the adequate penetration of the bonding agent, therby reducing the micotag formation. Hence, complete isolation is essential.

Dental MaterialsThe acidic monomer helps to dissolve the smear layer for better penetration and bonding.
