总结。对13只Sprague-Dawley大鼠进行深度麻醉，并在上第一磨牙处制备空腔。这些纸浆被暴露出来，并盖上与蒸馏水混合的氢氧化钙，或与丁香酚混合的氧化锌。连续的牙齿切片分别用苏木精和伊红或革兰氏染色染色。两组牙髓均可见炎性浸润；两组中大约一半的牙齿都存在牙本质桥，几乎所有的牙齿都检测到细菌。他们局限于牙髓的表面部分，几乎没有穿透重要牙髓组织的证据。在与这两种材料直接接触时，观察到明显的活菌。
Summary. Thirteen Sprague-Dawley rats were deeply anaesthetized and cavities were prepared in the upper first molar teeth. The pulps were exposed and capped with either Analar calcium hydroxide mixed with distilled water, or Analar zinc oxide mixed with eugenol. Serial sections of the teeth were stained with either haematoxylin and eosin or the Gram Weigert stain. Inflammatory infiltrates were observed in the pulps in both groups; dentine bridges were present in a approximately half the teeth in both groups, and bacteria were detected in almost all the teeth. They were confined to the superficial parts of the pulp with little evidence of penetration of vital pulp tissue. Apparently viable micro- organisms were observed in direct contact with both materials.
