The combination of various possibilities for sample preparation and investigation--the tinting penetration method, the ion beam slope cutting, the light and scanning electron microscopy--allow statements at the grind after different drying of the preparation mainly to the bond but also surface and filler shape of glass-ionomer cements. The dentine in the area of enamel-dentine-junction and of superficial root area is effectively closed by Ketac-Bond. Likewise, the bond with cover filling (Visio-Molar) can be considered without gaps except a single case. Crack propagations from the cement surface seem to related to pores and occur independently of type of drying especially in case of mechanical after treatment of already hardened cavity lining [correction of underfilling] material.
样品制备和研究的多种可能性相结合——染色渗透法、离子束斜切、光学显微镜和扫描电子显微镜——使得在对制备物进行不同干燥处理后的研磨过程中，不仅可以对玻璃离子水门汀的粘结情况，还能对其表面和填料形状进行描述。在釉质-牙本质交界处和浅表牙根区域的牙本质能被Ketac-Bond有效地封闭。同样，与覆盖充填材料（Visio-Molar）的粘结在个别情况外可认为无间隙。从水门汀表面开始的裂纹扩展似乎与孔隙有关，且与干燥类型无关，尤其在对已硬化的窝洞衬层材料进行机械后处理（充填不足的校正）时会出现这种情况。
