Taglike projections of resin into the etched enamel surface and longitudinally cut enamel were studied under the SEM. Three methods of bonding, including the use of a bonding agent and a primer, were compared. Freshly extracted teeth were pumiced, rinsed, and dried. The enamel surface was etched for a minute with phosphoric acid. Adaptic with bonding agent, Simulate with primer, and Simulate without primer were then applied to the etched enamel. After the teeth were sectioned, the enamel was etched with phosphoric acid and viewed under the SEM. The resin projections into the etched rod ends at the enamel surface were 5 to 10 mu in length, with similar cuplike and coneline patterns of tags for the three methods of bonding. Troughlike and ridgelike projections into the longitudinally cut enamel were 3 to 5 mu in length; patterns of tags were similar for the three bonding methods. No observable differences in length and pattern of tags were noticed among the three bonding methods.
在扫描电子显微镜下研究了树脂向蚀刻牙釉质表面和纵向切割牙釉质的标签状突起。比较了三种粘结方法，包括使用粘结剂和底漆。将新鲜拔除的牙齿用浮石打磨、冲洗并干燥。用磷酸蚀刻牙釉质表面一分钟。然后将使用粘结剂的Adaptic、使用底漆的Simulate和不使用底漆的Simulate应用于蚀刻后的牙釉质。牙齿切片后，用磷酸蚀刻牙釉质并在扫描电子显微镜下观察。树脂在牙釉质表面蚀刻的釉柱末端的突起长度为5至10微米，三种粘结方法的标签杯状和锥形图案相似。向纵向切割牙釉质的槽状和脊状突起长度为3至5微米；三种粘结方法的标签图案相似。三种粘结方法在标签长度和图案上未观察到明显差异。
