| 内容記述 | In this investigation, the effect of bonding agents with light curing compsite resins on the gap prevention between dentin walls and compsite resins and the shear bond strength were studied immediately after the polymerization of light curing composite resins. Dentin cavities were prepared of which shape was cylindorical, 3mm in diameter, 1.3mm in depth and 90°cavosurface angle. Three brands of bonding agents (Gluma, Scotchbond Le. And Clearfil N.B.) and three brands of light curing composite resins (Lumifor, P 30 and Clearfil Ray) were used, resulting in 9pairs of combination. Immidiately after the light emission to the composite resins, teeth were cut through the center of restorations. Gars along the axial walls and the cavity floors were measured under the microscope equiped with measuring ocular. Shear bond strength between the composite resins and dentin mediated with the bonding agents was determined with the crosshead speed of 1mm/min about 2min after the irradiation of light source. The findings were as follows : \n1. 4-10μm of reduction in gap width was exhibited by means of use of bonding agents tested in this study, comparing to those produced without bonding agents.\n2. Gaps at cavity floors were generally wider than those at axial walls.\n3. The effective combinations of bonding system and light activated composite resin showed gaps which widths were less than 5μm even though at cavity floor.\n4. 8 MPa of shear bond strength was recorded from effective combinations of bonding system and light activated composite resin.\n5. There were disagreements in some cases between the shear bond values and cavity adaptation results. This would be caused by the difference of stress concentration pattern in both specimens totally induced at curing of the composite resins. | |||||
