Aim This study set out to explore the association between obstructive sleep apnoea (OSA) and prior chronic periodontitis (CP) by utilizing a population-based data set with a case-control design in Taiwan. Materials and Methods We included 7673 subjects with OSA as cases, and randomly selected 21,963 subjects without a history of OSA as controls. We performed conditional logistic regression analyses to explore the association between OSA and having been previously diagnosed with CP. Results There was a significant difference in the prevalence of prior CP between cases and controls (33.8% versus 22.6%, p <0.001). Conditional logistic regression analysis suggested that the odds ratio of prior CP for cases was 1.75 (95% CI = 1.68-1.88) times greater than that of controls after adjusting for monthly income and geographical location, as well as hypertension, diabetes, coronary heart disease, hyperlipidaemia, obesity, tobacco use disorder, and chronic obstructive pulmonary disease and alcohol abuse. Conclusion Our study detected an association between OSA and a prior diagnosis of CP.
