Biologic acceptance is one of several criteria that must be met by an endodontic filling material. The purpose fo this experiment was to compare a new filling material consisting of a synthetic gutta-percha with a standard material consisting of natural gutta-percha. Each sample, being an endodontic point, contained a quantity of fillers. The materials were implanted subcutaneously in male white rats. The histologic appearance was essentially identical for both materials.
生物相容性是牙髓填充材料必须满足的若干标准之一。本实验的目的是比较一种由合成牙胶组成的新型填充材料与一种由天然牙胶组成的标准材料。每个样本为一根牙髓尖，含有一定量的填料。将这些材料皮下植入雄性白色大鼠体内。两种材料的组织学外观基本相同。
