The subpressure technique was applied to improve the bonding properties of total-etching adhesive to dentin.12 caries-free premolars of human were selected as objectives with removed occlusal enamel to expose occlusal dentin.They were randomly divided into four groups.A control group (C) was treated according to the manufacturer instructions (3M Single Bond 2).Three experimental groups (S) were treated under 0.8,0.6 and 0.4 atm,which were named as S8,S6 and S4,respectively.Bonding interface was examined on scanning electron microscope (SEM).
