临床和实验资料证明,健康牙髓的反应能力极好,能清除病灶,能使病变部位形成包膜、隔离健康组织和炎性组织。牙髓的防御能力主要源于网状内皮组织包括组织细胞成分。但牙周炎时病原菌入侵过程中牙髓的反应可能性问题至今仍未解决。作者检查了牙周炎患者拔除的20颗牙,将其牙髓组织制成切片,用电子显微镜和光学显微镜检查。结果,发现所有残余的结缔组织和 Clinical and experimental data show that the healthy dental pulp excellent response ability to clear the lesion, the lesions can form a capsule, isolated from healthy tissue and inflammatory tissue. Dental pulp defense is mainly due to reticuloendothelial tissue, including tissue cells. However, during periodontitis pathogenic bacteria in the process of pulp reaction potential problem remains unresolved. The authors examined 20 teeth removed from patients with periodontitis, sliced ​​their pulp tissue and examined by electron microscopy and light microscopy. As a result, all remaining connective tissue was found
