[The tooth-amalgam joint: the role of the marginal bevel].
Three amalgams, Standalloy, Dispersalloy and Formibel are used to fill class I cavities (bevelled or not) and applied over fresh-removed wisdom teeth. Macroscopic examination with a binocular lamp shows a better marginal adaptation of amalgams when cavity walls and edges have no asperity nor bevel and regardless of the quality of the amalgam. This MEB examination reveals a gap at dentinal level that might result from the vacuum processing of the samples.
