The shear bond strength to human dentin and enamel was evaluated for four glass-ionomer cements: an experimental stainless steel-reinforced glass-ionomer cement, two commercially available silver-reinforced cements, and a conventional glass-ionomer cement. Bonded specimens were stored in distilled water for 7 days during which time they were subjected to thermocycling in water baths at 5 degrees C and 55 degrees C for a 1-minute dwell time per bath and 1500 cycles. Specimens were then shear tested. The experimental stainless steel-reinforced glass-ionomer cement had a significantly higher bond strength to enamel (P < .01) and dentin (P < .05) than did the commercially available cements.
一种实验性不锈钢增强玻璃离子水门汀、两种市售银增强水门汀和一种传统玻璃离子水门汀。粘结标本在蒸馏水中储存7天，在此期间，它们在5摄氏度和55摄氏度的水浴中进行热循环，每个水浴的停留时间为1分钟，循环1500次。然后对标本进行剪切测试。实验性不锈钢增强玻璃离子水门汀与牙釉质（P < 0.01）和牙本质（P < 0.05）的粘结强度明显高于市售水门汀。
