Seven glass-ionomer cements were tested and compared with a composite resin in order to find the glass-ionomer cement with the highest bond strength to enamel with normal anatomy and composition (not ground). Five types of surface treatment were used. The results show that Aqua Cem and Ketac Cem, both water-hardening, present the highest bond strength, followed by the conventional glass-ionomer cement Fuji IIF. Surface treatment according to the manufacturers' instructions and surface treatment with polyacrylic acid were found to give rise to the highest bond strength for all of the seven cements. However, none of the glass-ionomer cements reached the values for the composite resin Concise. The testing instrument designed for ex vivo purposes measured with high precision and accuracy and with a low methodological error.
测试了七种玻璃离子水门汀，并与一种复合树脂进行比较，以找出对正常解剖结构和成分（未研磨）的牙釉质具有最高粘结强度的玻璃离子水门汀。使用了五种表面处理方法。结果表明，两种水硬性的Aqua Cem和Ketac Cem具有最高的粘结强度，其次是传统的玻璃离子水门汀Fuji IIF。按照制造商说明进行的表面处理以及用聚丙烯酸进行的表面处理，对于所有七种水门汀而言都产生了最高的粘结强度。然而，没有一种玻璃离子水门汀达到复合树脂Concise的数值。专为体外目的设计的测试仪器测量精度高、准确性好且方法误差小。
