Fig. 3From: Effect of surface treatments on push-out bond strength of calcium silicate-based cements to fiber postsRepresentative SEM photomicrographs (×500) for the surface microstructure of a–d RP and e–h RX posts; respectively with different treatments. White arrows showed fractured glass fibers, yellow arrows showed the cracks in the glass fibers, and the black arrows showed the exposed glass fibersBack to article page
