Abstract
Objective:To evaluate the effects of different dentin conditions on micoleakage of luting resin composite inlays using a self-adhesive resin cement,Embrace wetbond resin cement. Method:According to the requirement of class Ⅱcavity,40 freshly extracted non-carious human molar were prepared and randomly divided into four groups according to dif-ferent treatment. The group were treated respectively with nothing,Adaper Easyone,Singglebond 2 and 37 % H3PO4. Com-posite resin inlays were fabricated and were luted with Embrace wetbond resin cement. After bonding,all specimens were immersed in water for thermo-cycling test,for 500 times.after dyeing for 24 hours,each specimens were cut longitudinally a-long the long axis.with the help of stereomicroscope,the microleakage of each specimens were observed and measured. Re-sult:A-group showed the most microleakage with a statistically significant difference to B-group C-group and D-group both in occlusal wall and gingival wall.Microleakage at the gingival wall was significantly greater than that at occlusal wall in D-group. Conclusion:Acid etching can reduce the microleakge at the tooth-resin interface before bonding with Embrace wet-bond resin cement,The gingival sealing was poorer than the occlusal sealing when using phosphoric acid alone.关键词
