Eight materials were placed as bases on the pulpal surface of cavities prepared in extracted teeth. Seven minutes after mixing of the material commenced, amalgam was condensed on to the lined cavity. The restored teeth were sectioned subsequently for microscopic examination. The results suggested that all uniformly mixed, carefully placed base forming materials that have reached the state of "clinical set" are able to withstand loads applied during amalgam condensation irrespective of their strength.
将八种材料作为基底置于拔除牙齿制备的窝洞牙髓表面。材料混合开始七分钟后，将汞合金填入衬有基底的窝洞。随后将修复后的牙齿进行切片以便显微镜检查。结果表明，所有均匀混合、小心放置且已达到“临床凝固”状态的基底形成材料，无论其强度如何，都能够承受汞合金充填过程中施加的负荷。
