| Research Abstract |
The aim of this study was to classify a lot of commercially available one-step adhesive systems according to the ability to remove (dissolve) clinically produced smear-layer, and to evaluate their short- and long-term bonding effectiveness.
Within the limit of the results of the present project, it is concluded that their classification as one of the aims of this study was very difficult to be perfomed by the ability to remove clinically produced smear-layer, and also indicated that the selection of burs or points to cut tooth substrates is thought to be very important in case of the application of one-step adhesive systems because some adhesive systems decrease the bond strength after 100,000 times thermo-cycle stress when bonded to the dentin surfaces produced with a regular-grit diamond bur.
