The Study Of The Association Between Periodontitis And Lung Disease

Objective:To study periodontal disease and bedridden elderly patients with severe lung infection and the relationship between chronic obstructive pulmonary disease.Methods:The three ways to explore the relationship between periodontal disease and lung disease. First, the establishment of periodontal disease and lung infection in experimental animal models to observe the superposition of the two models is likely to increase after infection, and to observe the severity of periodontal disease and lung infections between the two affect each other. Followed by respiratory lung infection by collecting the general condition of the elderly, lung infection and periodontal condition, etc., while recording the same number of older persons without lung disease as control, to understand severe lung infection in elderly bedridden patients in subgingival plaque aerobic bacteria colonization and its relationship with lung infection pathogens. Finally, examination of the participants through a higher cultural level, Hangzhou oral health survey of elderly people, trying to explore in this population based on the periodontal health status and chronic obstructive pulmonary disease (COPD) prevalence epidemiological relationship.Results:severe periodontal disease in their lungs of mice was significantly higher periodontal pathogens, severe lung infections in patients bedridden elderly in subgingival plaque colonization of aerobic bacteria was significantly higher than the control group,1945by seized a total of253patients were diagnosed with COPD, the prevalence of13.02%. COPD group, the mean AL of each section is generally higher than non-COPD group.Conclusion:Periodontal infection can cause or aggravate serious lung infection; between severe attachment loss associated with COPD, control of periodontal disease will help control lung disease.
