This study evaluated the microleakage resistance of various glutaraldehyde-containing dental adhesives in Class V preparations. The materials tested were Gluma Bond System (3 Step), Prisma Universal Bond 3, and Syntac. The Class V preparations extended just beyond the cemento-enamel junction of extracted human molars. The restored teeth were stored in tap water for 24 hours and then thermally stressed for 100 cycles. Marginal leakage was assessed by measuring the dye linear penetration. The results indicated that all three dentin bonding agents provided leak-proof seals under certain conditions. The sealing ability of the Gluma Bond System (3 Step) appeared to be significantly affected by the resin composite used in the restoration.
本研究评估了含戊二醛的各类牙科粘结剂在Ⅴ类洞修复中的微渗漏抗性。测试材料为Gluma Bond System（三步法）、Prisma Universal Bond 3和Syntac。Ⅴ类洞修复延伸至离体人磨牙的牙骨质-釉质界以外。修复后的牙齿在自来水中储存24小时，然后进行100次热循环应力测试。通过测量染料线性渗透来评估边缘渗漏情况。结果表明，在特定条件下，所有三种牙本质粘结剂均能提供防渗漏密封。Gluma Bond System（三步法）的密封能力似乎受到修复中使用的树脂复合材料的显著影响。
