title: [Time of extraction and cavity position in in-vitro tests of dentin adhesives].
abstract: Cylindrical cavities were prepared in different tooth segments (coronal, cervical and radicular) and at different times (1 hour, 1 day, 1 week and 1 month) after extraction into face-ground dentin surfaces of extracted teeth. The cavities were filled with composite resin materials using different dentin adhesives. Before and after thermocycling (TC) the marginal adaptation was evaluated using defined criteria. The statistical evaluation did not show any significant differences (p greater than 0.01) after TC within the different groups of dentin adhesives. For in vitro tests of dentin adhesives neither the position nor the time of extraction decisively influences the process.
