[The surface structure of dentin after routine treatments].
A scanning electron microscopic study was made of the dentinal surface following preparation with various devices used routinely in the dental practice. The dentine prepared with diamond points showed deep fissured tracks from the individual diamond crystals, even when only slightly magnified. Compared with the untreated dentinal fracture surface, the orifices of the dentine tubules were crushed and obstructed. The surface is smoothed via finishing; the orifices of the dental tubules are no longer present. The picture remained unchanged after washing with H2O2 and cauterization with Ca(OH)2.
