Figure 2. TEM micrographs of non-stained, non-demineralized, and silver-impregnated sections illustrating the interfacial nanoleakage of Clearfil SE Bond bonded to 4 dentin subgroups with different characteristics: superficial perpendicular dentin (A), deep perpendicular dentin (B), superficial parallel dentin (C), and deep parallel dentin (D). On each micrograph: A, filled adhesive; D, dentin; DT, dentinal tubule; H, hybrid layer; T, resin tag. Open triangles show fillers from bonding resin. The silver deposits within the hybrid layer consisted mainly of scattered dots of metallic silver. (A,C,D) Sparsely dispersed fine dots of silver impregnation (hand pointers). (B) Increased size and density of silver impregnation within the hybrid layer (black solid arrows).
