摘要: BACKGROUND To evaluate the effects of adhesive systems and primer on microshear bond strength chemically activated resin cemented to Co-Cr cast dental alloy. METHODS Seventy-two rectangular blocks metal alloy were manufactured air-abraded with 50-μm Al2O3 particles. Metal primers (alloy [AP] or Clearfil ceramic [CP]) adhesives (Adper Scotchbond Multi-Purpose Adhesive by Adper Catalyst [SASC], Primer & Bond 2.1 Self Cure Activator [PBCA]) applied subsequently divided into six groups (SASC; AP+SASC; CP+SASC; PBCA; AP+PBCA; CP+PBCA; N.=12). Then, cement (Enforce) was applied. Data about values statistically evaluated analysis variance Tukey's test. RESULTS The lower (P<0.001) in system alone (SASC PBCA) compared addition (AP+SASC AP+PBCA) (CP+SASC CP+PBCA). CONCLUSIONS application improves
