Popis: Although most transmission electron microscope (TEM) investigations were carried out using conventional ultramicrotomy, they were limited to the tooth/adhesive resin interface and were difficult to accomplish for the resin-composite interface. Some of these limitations have been overcome with the introduction of focused ion beam (FIB) milling. Therefore, the objective of the study was to compare different composites/adhesive interfaces using FIB/TEM technique. Cylindrical cavities were prepared in extracted human molar teeth. The restored cavities were divided into four groups: (1) One-step self-etch Scotchbond Universal (SBU; 3M ESPE, USA), (2) all-in-one Xeno-V+ adhesive (X5P; DENTSPLY, Germany), (3) two-step etch-and-rinse Prime and Bond NT (PNT; DENTSPLY, Germany) that were restored with Filtek Supreme Ultra Universal composite (3M ESPE, USA), and (4) teeth restored with the two-step self-etch Filtek Silorane adhesive (SSA; 3M ESPE, USA) that were restored with its corresponding Filtek Silorane compos...
