“…On the contrary, El Zayat et al (29) experiment concluded that HF acid etching to zirconia revealed the lowest results regarding the bond strength. This conclusion was confirmed by several studies counseled by Pjetursson et al (4) , Inakuchi et al (14) and Saleh et al (7) .…”

“…One important aspect influencing the clinical effectiveness of ceramic restorations is the bond's longevity (5) . Ceramic surface treatments, either mechanical (sandblasting) (6) or chemical (hydrofluoric acid (HF) etching) (7) , aim to improve bond strength. However, the wet oral environment and prolonged chewing forces make creating a long-lasting bond very challenging (8,9) .…”

Objective:The purpose of this study was to evaluate the effect of two surface treatment protocols and aging on the shear bond strength (SBS) values of monolithic zirconia and lithium di-silicate glass ceramic. Materials and methods:Eighty ceramic specimens were separated into groups to evaluate SBS using a universal testing machine. There were two main groups based on ceramic material: lithium disilicate glass ceramic (IPS e.max CAD) and monolithic zirconia (IPS e.max ZirCAD prime). Each main group was further subdivided into two surface treatment subgroups of 20 specimens each: (1) hydrofluoric acid etching with silane coupling agent (2) sandblasting. Additionally, each surface treatment subgroup was split into two classes: before and after thermocycling. All ceramic plates were bonded using a light-cured resin cement. SBS data was collected for statistical analysis.Results: Thermocycling significantly decreased the SBS mean values concerning zirconia ceramic with sandblasting from (13.01 ± 3.89) to (3.12 ± 0.96), while with hydrofluoric acid mean values from (9.8 ± 3.0.) to (2.36 ± 0.35). Zirconia ceramic revealed significantly lower SBS than lithium disilicate in all groups P<0.05. Conclusion:Thermocycling decreased the SBS of both ceramics regardless of surface treatment type applied. Sandblasting surface treatment was better than hydrofluoric acid with silane when applied to zirconia ceramic. IPS ZirCAD prime ceramic still revealed weaker bond stability in comparison with IPS e.max CAD ceramic.
