Influence of Polishing Methods on the Bonding Effectiveness and Durability of Different Resin Cements to Dentin

Figure 2

Representative SEM micrographs of the dentin side of the fractured specimen. (a) Adhesive failure, failure within dentin/resin cements interface; (b) cohesive failure, failure solely within resin cements; (c) mixed failure, partially cohesive failure within resin cements with some adhesive failure. A: adhesives; D: dentin; RC: resin cements. The dentinal tubules on the dentin surface (white arrow).
