View larger version (169K): [in this window] [in a new window]   Figure. Transmission electron micrographs of demineralized, stained sections taken from (A) a chlorhexidine-pre-treated experimental specimen retrieved after 14 mos of intra-oral function; and (B,C,D) multiple control specimens retrieved after 14 mos of intra-oral function, showing the 4 progressive stages of hybrid layer degradation. Captions applicable to all specimens: C, resin composite; A, dentin adhesive; D, intertubular dentin. Caption exclusive to (A): H, hybrid layer. Captions applicable to (B-1D): 1, zone of integrity, where no ultrastructural features of hybrid layer degradation can be observed; 2, zone of partial disintegration, where sparsely distributed, banded collagen fibrils can still be identified; 3, microfibrillar zone, where the multi-stranded collagen fibrils have disintegrated into their microfibrillar components; and 4, zone of complete disintegration, where no fibrillar characteristics can be seen, and regions appear completely amorphous.
