Margins are one of the most important aspects in the success of restorations. Therefore, we evaluated the effects of different metal surface treatments on the marginal microleakage of a resinbonded non-precious alloy (Remanium CS). After alloy surfaces were roughened by chemical etching or sandblasting the tooth and metal specimens were bonded together in pairs with a chemically curing resin cement (Panavia 21 EX) and placed in methylene blue dye. Spectrophotometry was used to assess marginal leakage. Statistical analysis was completed using the ANOVA test. No statistically significant difference in leakage was found between the groups (F=0.4387, p>0.05).
