The resin-dentin interface of in vivo specimens restored with the All-Bond 2 system by use of a total-etch wetbonding technique on vital deep human dentin was investigated by: (a) SEM examination of cryofractured specimens; (b) SEM examination of acid-rinsed, highly polished, embedded specimens; and (c) TEM examination of demineralized ultrathin sections. Ultrastructural features that were pert...
