Abstract：AIM:To observe the effects of different curing methods of total etching dentin adhesive on the microleakage of Ceramage polymerization porcelain inlay.METHODS:Class II cavities on mesial-occlusal and distal-occlusal surfaces were prepared on 20 extracted premolars.Ceramage polymerization porcelain inlays were made. The mesial cavities(control group)were etched with total etching dentin adhesive and the adhesive was cured by tradi-tional curing method,then inlays were adhered by resin cement.The distal cavities(experiment group)were etched with total etching dentin adhesive,inlays were adhered by resin cement,then both adhesive and resin were light -cured simultaneously.After fuchsin staining,the teeth were splited twice and the depth of dye penetration was observed under optical microscope.RESULTS:The microleakage of the experiment group was lower than that of the control group,but with no statistic difference (P>0.05).The microleakage of gingival wall was significantly higher than that of shaft wall within the same group (P<0.05 ).CONCLUSION:Total etching dentin adhesive without curing may result in the same microleakage level as the total etching dentin adhesive with curing.Shaft wall microleakage is less than gingival wall.
