Post-experiment SEM. (a) CC group; no hybrid layers nor resin tags under 500x magnification. (b) NC group; dense and continuous hybrid layers and resin tags under 500x magnification. (c) AC group; dense and continuous hybrid layers and resin tags under 500x magnification. (d) NC group; dense and continuous hybrid layers and resin tags under 1600x magnification. (e) NC group; resin tags and micro resin tags that branch from main resin tags under 10000x magnification. D = dentine, C = resin cement layer, P = fibre post. Black arrows = hybrid layer. White solid arrows = resin tags. White dotted arrows = micro tags
