عنوان انگلیسی Effect of 4-META on microtensile bond strength of cements to ceramics
چکیده انگلیسی مقاله Background: This study assessed the effect of different concentrations of 4‑methacryloyloxyethy trimellitate anhydride (4‑META) added to silane on microtensile bond strength (μTBS) of light‑cure and dual‑cure resin cement to hybrid and zirconia‑reinforced lithium silicate ceramics. Materials and Methods: This in vitro, experimental study was conducted on 32 Celtra Duo and 32 VITA Enamic ceramics bonded to Allcem Veneer light‑cure and Allcem dual‑cure resin cements using silane impregnated with 4‑META in 0%, 2.5%, 5%, and 10 wt% concentrations in 16 groups (n = 4). The μTBS of specimens was measured by a universal testing machine and analyzed by the Kruskal–Wallis and Mann–Whitney tests, and the mode of failure was determined under a stereomicroscope and analyzed by the Chi‑square test (alpha = 0.05). Results: The lowest mean μTBS was recorded in the Enamic ceramic group with 4‑META (0%) bonded to dual‑cure cement (14.26 MPa), and the highest mean μTBS was recorded in Enamic ceramic with 4‑META (10%) bonded to light‑cure cement (18.59 MPa) (P < 0.001). The μTBS of Celtra Duo was significantly higher than that of Enamic in bonding to light‑cure cement using 4‑META (2.5%) (P = 0.003). All failures (100%) were adhesive in most groups. The frequency of adhesive failure was the lowest (90%) in Celtra Duo bonded to dual‑cure cement with 4‑META (5%). Conclusion: According to the results of this pilot study, the addition of 4‑META (10%) to silane caused a significant improvement in μTBS to light‑cure cement. The addition of 4‑META in all concentrations significantly improved the μTBS to Enamic ceramic in the use of dual‑cure cement; however, it had no significant effect on μTBS of Celtra Duo. Nonetheless, the results should be interpreted with caution due to the relatively small sample size. Key Words: Ceramics, resin cements, silanes, tensile strength
