Influence of silanes on the stability of resin-ceramic bond strength.

Purpose: To evaluate the in vitro stability of resin-ceramic bond strength provided for silanes with acidic functional monomers.

Methods: Five ceramic blocks were fabricated. The blocks were randomly divided into groups (n=30) and assigned to the following surface treatments: ( C) HF + RelyX Ceramic Primer, ( G1) HF + Porcelain Liner M, ( G2) HF + Clearfil Ceramic Primer, ( G3) Phosphoric acid ( H₃PO₄) + Clearfil Ceramic Primer, ( G4) H₃PO₄ + Porcelain Liner M.
