Oral health and mortality risk from pneumonia in the elderly 总被引:1,自引:0,他引:1

Although poor oral health influences the occurrence of pulmonary infection in elderly people, it is unclear how the degree of oral health is linked to mortality from pulmonary infection. Therefore, we evaluated the relationship between oral health and four-year mortality from pneumonia in an elderly Japanese population. The study population consisted of 697 (277 males, 420 females) of the 1282 individuals who were 80 years old in 1997. Data on oral and systemic health were obtained by means of questionnaires, physical examinations, and laboratory blood tests. One hundred eight of the study persons died between 1998 and 2002. Of these, 22 deaths were due to pneumonia. The adjusted mortality due to pneumonia was 3.9 times higher in persons with 10 or more teeth with a probing depth exceeding 4 mm (periodontal pocket) than in those without periodontal pockets. Therefore, the increase in teeth with periodontal pockets in the elderly may be associated with increased mortality from pneumonia. 相似文献

The oral cavity has long been considered a potential reservoir for respiratory pathogens. The mechanisms of infection could be aspiration into the lung of oral pathogens capable of causing pneumonia, colonization of dental plaque by respiratory pathogens followed by aspiration, or facilitation by periodontal pathogens of colonization of the upper airway by pulmonary pathogens. Several anaerobic bacteria from the periodontal pocket have been isolated from infected lungs. In elderly patients living in chronic care facilities, the colonization of dental plaque by pulmonary pathogens is frequent. Notably, the overreaction of the inflammatory process that leads to destruction of connective tissue is present in both periodontal disease and emphysema. This overreaction may explain the association between periodontal disease and chronic obstructive pulmonary disease, the fourth leading cause of death in the United States. These findings underline the necessity for improving oral hygiene among patients who are at risk and those living in long-term care institutions. 相似文献

Oral diseases, such as caries and periodontitis, not only have local effects on the dentition and on tooth‐supporting tissues but also may impact a number of systemic conditions. Emerging evidence suggests that poor oral health influences the initiation and/or progression of diseases such as atherosclerosis (with sequelae including myocardial infarction and stoke), diabetes mellitus and neurodegenerative diseases (such as Alzheimer's disease, rheumatoid arthritis and others). Aspiration of oropharyngeal (including periodontal) bacteria causes pneumonia, especially in hospitalized patients and the elderly, and may influence the course of chronic obstructive pulmonary disease. This article addresses several pertinent aspects related to the medical implications of periodontal disease in the elderly. There is moderate evidence that improved oral hygiene may help prevent aspiration pneumonia in high‐risk patients. For other medical conditions, because of the absence of well‐designed randomized clinical trials in elderly patients, no specific guidance can be provided regarding oral hygiene or periodontal interventions that enhance the medical management of older adults. 相似文献

Background: Recent research indicated that periodontal infection may worsen systemic diseases, including pulmonary disease. Respiratory infections, such as pneumonia and the exacerbation of chronic obstructive pulmonary disease, involve the aspiration of bacteria from the oropharynx into the lower respiratory tract. Methods: A group of 100 cases (hospitalized patients with respiratory disease) and a group of 100 age‐, sex‐, and race‐matched outpatient controls (systemically healthy patients from the outpatient clinic, Department of Periodontics, Government Dental College and Hospital, Calicut, Kerala, India) were selected for the study. Standardized measures of oral health that were performed and compared included the gingival index (GI), plaque index (PI), and simplified oral hygiene index (OHI). Data regarding probing depths and clinical attachment levels (CALs) were recorded at four sites per tooth and compared statistically. The χ2 and Student t tests were used for statistical analyses. Results: The comparison of study‐population demographics on the basis of age, sex, education, and income showed no significant differences between groups. Patients with respiratory disease had significantly greater poor periodontal health (OHI and PI), gingival inflammation (GI), deeper pockets, and CALs compared to controls. In the case group, patients with a low income were 4.4 times more prone to periodontal disease compared to high‐income patients. Smokers had significantly higher CALs compared to non‐smokers in the control group. Conclusion: The findings of the present analysis support an association between respiratory and periodontal disease. 相似文献

Role of oral bacteria in respiratory infection. 总被引:10,自引:0,他引:10
F A Scannapieco 《Journal of periodontology》1999,70(7):793-802
An association between oral conditions such as periodontal disease and several respiratory conditions has been noted. For example, recent evidence has suggested a central role for the oral cavity in the process of respiratory infection. Oral periodontopathic bacteria can be aspirated into the lung to cause aspiration pneumonia. The teeth may also serve as a reservoir for respiratory pathogen colonization and subsequent nosocomial pneumonia. Typical respiratory pathogens have been shown to colonize the dental plaque of hospitalized intensive care and nursing home patients. Once established in the mouth, these pathogens may be aspirated into the lung to cause infection. Other epidemiologic studies have noted a relationship between poor oral hygiene or periodontal bone loss and chronic obstructive pulmonary disease. Several mechanisms are proposed to explain the potential role of oral bacteria in the pathogenesis of respiratory infection: 1. aspiration of oral pathogens (such as Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, etc.) into the lung to cause infection; 2. periodontal disease-associated enzymes in saliva may modify mucosal surfaces to promote adhesion and colonization by respiratory pathogens, which are then aspirated into the lung; 3. periodontal disease-associated enzymes may destroy salivary pellicles on pathogenic bacteria to hinder their clearance from the mucosal surface; and 4. cytokines originating from periodontal tissues may alter respiratory epithelium to promote infection by respiratory pathogens. 相似文献

Aim
To evaluate the association between periodontal disease and pneumonia mortality in haemodialysis patients.Materials and Methods
This prospective cohort study included 211 patients (mean age, 64.4 years) undergoing haemodialysis at a single medical centre. The patients underwent a baseline clinical dental examination in 2008 and were then followed up until July 2015. Periodontal disease was defined as the presence of clinical attachment loss of ≥4 mm in ≥30% of the probed sites. The primary endpoint, that is death from pneumonia, was determined by reviewing death certificates and was analysed using the competing‐risks regression model.Results
At baseline, 92 patients (43.6%) had periodontal disease. The median follow‐up period was 84 months (interquartile range, 36–86 months). Of the 68 deaths that occurred, 21 were from pneumonia. The multivariable competing‐risks regression model showed that periodontal disease was significantly associated with death from pneumonia (adjusted subhazard ratio, 3.49; 95% confidence interval, 1.14–10.64), after adjusting for other baseline health characteristics.Conclusions
The results of this study suggest that periodontal disease is independently associated with pneumonia mortality in haemodialysis patients. Future studies evaluating the potential effect of oral interventions for periodontal health improvement on pneumonia in haemodialysis patients would be of great interest. 相似文献17.
Bacteria from the oral biofilms may be aspirated into the respiratory tract to influence the initiation and progression of systemic infectious conditions such as pneumonia. Oral bacteria, poor oral hygiene, and periodontitis seem to influence the incidence of pulmonary infections, especially nosocomial pneumonia episodes in high-risk subjects. Improved oral hygiene has been shown to reduce the occurrence of nosocomial pneumonia, both in mechanically-ventilated hospital patients and non-ventilated nursing home residents. It appears that oral colonization by potential respiratory pathogens, possibly fostered by periodontitis, and possibly by bacteria specific to the oral cavity or to periodontal diseases contribute to pulmonary infections. Thus, oral hygiene will assume an even more important role in the care of high-risk subjects--patients in the hospital intensive care and the elderly. The present paper critically reviews the recent literature on the effect of oral biofilms and periodontitis on pneumonia. 相似文献

BACKGROUND: Cigarette smoking is a significant risk factor for both chronic obstructive pulmonary disease (COPD) and periodontal disease. The goal of this study was to better understand the role of smoking in a possible relationship between periodontal disease and COPD. METHODS: The study population consisted of 7,625 participants in the Third National Health and Nutrition Examination Survey (NHANES III) during 1988-1994 who were aged 30 years or older when examined and who received a spirometric examination. The data analysis employed logistic regression models and accounted for the complex sampling design used in NHANES III. RESULTS: After adjustment for potential confounders, there was no statistically significant association between periodontal disease and COPD among former or non-smokers. Current smokers with > or = 4 mm mean loss of attachment had an odds ratio of 3.71 (95% confidence interval: 1.74, 7.89). CONCLUSIONS: These results suggest that cigarette smoking may be a cofactor in the relationship between periodontal disease and chronic obstructive pulmonary disease. The key role played by smoking in the etiology of both periodontal disease and chronic obstructive pulmonary disease suggests that much of the observed increase in risk may actually reflect the exposure to smoking. Additional research into smoking-related effect modification is needed to clarify the role of periodontal disease in the etiology of smoking-related systemic diseases. 相似文献

Recent studies in periodontal medicine suggest a mild to moderate association between human periodontal disease and certain systemic disorders such as diabetes mellitus, pneumonia, heart disease and preterm birth. The latest evidence, presented at a symposium entitled Periodontal Health and Systemic Disorders, sponsored by the University of Western Ontario School of Dentistry, showed that indeed such an association is likely. New data suggest that this association is not indicated by traditional clinical signs of periodontal disease but rather by a cluster of host immune and inflammatory mediators. The coming era of periodontal medicine based upon molecular criteria will affect the future of periodontal diagnosis, treatment and professional practice. 相似文献
