Push-out bond strength, distribution of failure mode, and SEM evaluation of adhesive failure: (a) push-out bond strength; (b, c) microscopic views of adhesive failure and mixed failure, respectively; (d) distribution of failure modes; (e, f) lower and higher magnification views of the adhesive failure of DW; (g, h) lower and higher magnification views of the adhesive failure of V125; (i, j) lower and higher magnification views of the adhesive failure of V125E8. ∗P < 0.05 compared to the DW group; ∗∗P < 0.05 compared to both the DW and V125 groups.
