عنوان انگلیسی Bond strength of self‑adhesive resin cement to base metal alloys having different surface treatments
چکیده انگلیسی مقاله Background: This study aimed to assess and compare the shear bond strength of self ‑ etch and self ‑ adhesive resin cement to nickel ‑ chromium ‑ cobalt alloy with different surface treatments. Materials and Methods: In this in vitro study, a total of 120 disks were fabricated of VeraBond II base metal alloy. Specimens were divided into 15 groups of 8 based on the type of cement and surface treatment. The five surface treatments studied included sandblasting alone, application of Alloy Primer with and without sandblasting, and application of Metal Primer II with and without sandblasting. The three cement tested included Panavia F2.0, RelyX Unicem (RU), and G ‑ Cem (GC). After receiving the respective surface treatments, the specimens were thermocycled for 1500 cycles and underwent shear bond strength testing. Data were analyzed using SPSS 20.0 and three ‑ way analysis of variance. P values of the significant level of 0.05 were reported. Results: The results exhibited that the mean bond strengths in sandblasted groups were higher than nonsandblasted one. These differences were significantly higher in the sandblasted groups of Panavia F2.0 and RU cement (P < 0.05).The mean bond strength values between GC and Panavia F2.0 were not statistically significant (P > 0.05). The highest bond strength was recorded for Panavia F2.0 with the surface treatment of both sandblasting and Metal Primer II. Conclusion: Based on the results, sandblasting improves the shear bond strength of self ‑ etch and self ‑ adhesive resin cement to base metal alloys. The best results can be achieved with a combination of sandblasting and metal primers. The performance of resin cement depends on to their chemical composition, not to the type of system. Key Words: Dental alloys, self-adhesive, resin cement, bond strength
