Increasingly higher concentrations of Phenyl-P in 30% HEMA were used as dentin conditioners to improve the bonding of adhesive resins to smear layers. The maximum bond strength (10.4 MPa) was obtained at a concentration of 20% Phenyl-P. Transmission electron microscopy of fractured, lightly smeared, and compactly smeared dentin demonstrated that 20% Phenyl-P in 30% HEMA demineralized the dentin surface by partially dissolving mineral crystals from around collagen. When applied to smear layers… CONTINUE READING
