This laboratory study evaluated the effect of a self-etching ceramic primer (Monobond Etch & Prime – MEP), with or without grit blasting, on the surface, mechanical, and adhesive properties of lithium disilicate (LD) ceramics, compared to hydrofluoric acid and silane (HF + S). LD specimens were prepared in two geometries: square-shaped (10 mm × 10 mm × 4 mm) for surface roughness ( Δ Sa, μ m), contact angle (CA), microtensile bond strength ( μ TBS), and scanning electron microscopy (SEM); and rectangular-shaped (15 mm × 2.5 mm × 1.5 mm) for three-point flexural strength ( σ f3P). Four groups were tested: HF + S grit-blasted (HF + S[g]), HF + S pol- ished (HF + S[p]), MEP[g], and MEP[p]. After treatment, Δ Sa, CA, and σ f3P were measured. LD blocks were cemented to composite or dentin to evaluate μ TBS before and after thermocycling (TC, 10,000 cycles, 5 ◦ C/55 ◦ C, 30 s dwell time). Grit blasting significantly increased Δ Sa (HF + S[g]: 1.16 ± 0.12; MEP[g]: 0.85 ± 0.02) compared to polished specimens (HF + S[p]: 0.47 ± 0.04; MEP[p]: 0.38 ± 0.04), with the lowest CA observed in MEP[g] (27.50 ± 4.09 ◦ ). HF + S-treated groups showed the lowest σ f3P. TC reduced μ TBS in all groups, but MEP-treated specimens exhibited greater adhesive stability ( Δμ TBS ≤ 2.0 MPa). Grit-blasted surfaces showed higher μ TBS than polished ones. HF + S and MEP performed similarly, except on composite before TC, where HF + S was superior. In conclusion, MEP[g] demonstrated μ TBS comparable to HF + S, provided greater adhesive stability after TC, enhanced wettability, better preserved σ f3P, reduced Δ Sa, and showed consistent μ TBS to resin cement on both dentin and composite substrates, supporting its effectiveness as a reliable surface treatment for LD ceramics.
