牙周病是人类失牙的主要原因。慢性牙周炎(chronic periodontitis,CP)是细菌及其产物引起的慢性感染性疾病,表现为牙龈出血、牙周袋形成和牙槽骨吸收。牙周微生物是慢性牙周炎发生的始动因子,有学者曾在牙龈沟内发现325种细菌。目前证实与牙周炎发生有关的可疑致病菌有十余种。久居于高原者,其牙周炎的患病率明显高于其他地区,高达70.2%,这可能是由于高原特殊环境尤其是缺氧环境对全身代谢和免疫、牙周组织、厌氧菌的生长和繁殖等均有影响引起的。本文通过调查高原、平原地区CP患者和牙周健康(periodontal healthy,PH)者龈下菌斑中致病菌的检出率,分析高原与平原地区慢性牙周炎
Periodontal disease is the main cause of human tooth loss. Chronic periodontitis (CP) is a chronically infectious disease caused by bacteria and their products. It manifests as gum bleeding, periodontal pocket formation and alveolar bone resorption. Periodontal microorganisms are the initiators of chronic periodontitis, and some scholars have found 325 kinds of bacteria in the gingival sulcus. Currently confirmed with the occurrence of periodontitis suspected pathogens have more than ten species. Living in the plateau, the prevalence of periodontitis was significantly higher than other regions, up to 70.2%, which may be due to the special plateau environment, especially hypoxia on the body metabolism and immune, periodontal tissue, anaerobic growth And breeding are all caused by the impact. In this paper, we investigated the prevalence of pathogenic bacteria in subgingival plaque in CP patients and periodontal healthy (PH) in plateau and plain area, and analyzed the relationship between chronic periodontitis
