Özet
Aim: Repairing amalgam restorations with composite resins is a clinicalpractice with many advantages. An effective adhesion is achievedbetween amalgam and composite by applied different surface treatmenton amalgam surface. In this study, the effect of adhesive systems appliedon amalgam surface on composite-amalgam connection was investigated.Methodology: Standard cavities were opened in 70 acrylic molds thathad completed their polymerization and amalgams were placed in thesecavities. Seven groups were randomly assigned to different surfacetreatments on amalgam. In group 1 only roughening with diamond bur, ingroup 2 acid etch, in group 3 acid application after roughening withdiamond bur, in group 4 roughening with diamond bur and silane, in group5 acid etch and silane, in group 6 roughening with diamond bur and AlloyPrimer and finally 7. acid etch and Alloy Primer was applied in thesamples. After the application of clearfil universal bond to all groups,composite resins were placed and polymerized. Shear bond strengthswere tested with a Universal testing machine. Obtained data wereevaluated by one way ANOVA and Tukey B tests.Results: In the statistical evaluation of the groups, the highest shearbond strength between amalgam-composite was seen in the 3rd groupwhere both roughening with diamond bur and acid were applied together,and the lowest shear bond strength was seen in the first group with onlyroughening with diamond bur. The differences between the groups werestatistically significant (p<0.05).Conclusions: The roughening of the amalgam surface affects the shearbond strength between amalgam and composite resin. These resultsobtained in vitro conditions should be supported with clinical studies.
