Association between oral health status and chronic obstructive pulmonary disease in Korean adults

Abstract

Objectives: This study aimed to elucidate the association between oral health status and chronic obstructive pulmonary disease (COPD) in Korean adults (≥ 40 years old) using a representative national dataset from the 6th Korea National Health and Nutrition Examination Survey (6th KNHANES, 2013-2015. Methods: Participants aged ≥ 40 years from the 6th KNHANES who had received an oral and pulmonary function tests (N = 7719) were included in this study. The participant characteristics according to COPD were compared using t-test and chi-squared test. Logistic regression analysis was used to estimate the association between oral health status and COPD. Results: Participants with poor periodontal status exhibited a higher prevalence of COPD. Moreover, patients with COPD had a greater number of missing teeth than those without COPD. The logistic regression model adjusted for demographic, socioeconomic, health-and oral health-related factors showed that the periodontal status was not significantly associated with COPD, while participants with more missing teeth had a significantly increased possibility of having COPD. Conclusions: This study revealed that loss of teeth in adults aged ≥ 40 years was associated with COPD.

Impaired Oral Health in Older Orthopaedic In-Care Patients: The Influence of Medication and Morbidity

“…Also, other chronic diseases that can have detrimental effects on oral health were present such as dementia (14%), obstructive lung diseases (13%) and rheumatoid arthritis (6%) whereas 50% presented with moderate to low renal function. Previous studies 55 , 56 have reported an association between missing teeth and COPD, which was also found in this study. We found a significant association between COPD in the dentate patients and the presence of fewer than 20 teeth or a DFT of over the mean, (p = value 0.019 and 0.048 respectively).…”

The association between periodontitis and lung function: Results from the National Health and Nutrition Examination Survey 2009 to 2012

“…Nevertheless, some other studies 23,24,40 showed that there was no significant association between periodontitis and airflow obstruction. Jung et al 24 stated that the periodontal status was not significantly associated with COPD. A crosssectional evaluation conducted by Lee et al 23 indicated that the risk of periodontitis was not significantly associated with lung function.…”

“…The results of linear regression showed a negative correlation between periodontitis and FEV1, FVC, and FEV1/FVC, which were consistent with the results of logistic regression analysis in the study. Nevertheless, some other studies 23,24,40 showed that there was no significant association between periodontitis and airflow obstruction. Jung et al 24 .…”

“…[16][17][18][19][20][21][22] Whereas some other studies have indicated no significant relationship between them. [23][24][25][26] The results for the association between periodontitis and lung function are not entirely consistent. Therefore, based on the data from the National Health and Nutrition Examination Survey (NHANES) 2009 to 2012, we intended to investigate the association between periodontitis and lung function.…”

“…To date, some epidemiological studies have suggested that periodontitis was a risk factor for lung function 16–22 . Whereas some other studies have indicated no significant relationship between them 23–26 . The results for the association between periodontitis and lung function are not entirely consistent.…”
