本文报告因严重系统性疾病死亡者其牙周组织中发生的变性变化,列举了六种疾病:痢疾、播散性红斑狼疮、结核、肾炎、肝炎及动脉硬化。牙周组织中表现的变性变化是多种多样的。常看到的有牙周膜的水样变性、粘液样变、玻璃样变、局灶性坏死和营养不良性钙化。牙槽骨的形成障碍,出现无定型骨或未成熟骨。牙骨质常见沉积不规则并有颗粒样钙化。以上这些变化都是全身性变化的一部分。单独的牙周变性并不致于引起临床上的牙周病,但可以认为它们是牙周病发生和发展的内因基础。 This article reports on changes in degeneration of periodontal tissues that have died of severe systemic disease, enumerating six diseases: dysentery, disseminated lupus erythematosus, tuberculosis, nephritis, hepatitis and arteriosclerosis. Degeneration of periodontal tissue showed a variety of changes. Often seen in the periodontal membrane watery degeneration, mucoid change, hyaline degeneration, focal necrosis and malnutrition calcification. Alveolar bone formation disorder, there amorphous bone or immature bone. Common deposition of cementum irregular and granular calcification. These changes are all part of a systemic change. Periodontal degeneration alone does not cause clinical periodontal disease, but they can be considered as an internal cause of the occurrence and development of periodontal disease.
