Abstract
Objective
To investigate the associations of asthma with dental-caries-experience (DFT: decayed and filled teeth) and untreated-dental-caries (DT: decayed teeth) in the US adult population.
Methods
Data from the National Health and Nutritional Examination Survey, 2009–2014 were analyzed. Study-participants were classified into current, former and never asthmatics based on their asthma-status. Former-asthmatics were excluded. Both the outcomes, dental-caries-experience and untreated-dental-caries were dichotomized as being either present or absent, and were also categorized into tertiles based on their distributions in our study-sample. Logistic regression analyses were performed to determine the associations of asthma with dichotomized outcomes. The generalized logit model was applied for multilevel categorical outcomes. Multivariable models were developed to control for common demographic, clinical, and lifestyle factors.
Results
Total study-participants were 13,135, representing 175.26 million US adults. In the adjusted models, current-asthmatics, when compared to the reference group of never-asthmatics, were more likely to have dental-caries-experience (odds ratio [OR], 1.37; 95% confidence interval [CI], 1.13–1.66) and untreated-dental-caries (OR, 1.38; 95% CI, 1.10–1.73) in ≥1 tooth. Asthma was associated with all three categories of dental-caries-experience in our study-sample. We observed a positive gradient in the OR with an increasing extent of untreated-dental-caries. Relative to never-asthmatics, asthma doubled the odds of having untreated dental caries in the subgroup of current-smokers.
Conclusion
Current-asthmatic adults had higher odds of dental-caries-experience and untreated-dental-caries as compared to never-asthmatic adults in the US. Based on the observations from this study, interprofessional collaboration should be recommended to institute caries control and health promotion in current-asthmatic adult population.
