Indicators of Oral and Dental Status and Risk of COPD

Objectives: To investigate associations between measures of oral and dental health and chronic obstructive pulmonary disease (COPD) in men in Northern Ireland enrolled in the Prospective Epidemiological Study of Myocardial Infarction (PRIME) study.
Methods: Men in the PRIME study had a comprehensive periodontal assessment and completed a questionnaire on their dental history and behaviour, medical history, social circumstances, demographic background and tobacco use. Spirometry measurements were undertaken and COPD was equated with a ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) of <0.7. Logistic regression analysis was used to calculate odds ratios (OR).
Results: In total 1380 men aged on average 64.2 (SD 2.9) years had both a dental examination and valid spirometry data. 248 (18%) of the men examined met the criterion for COPD. Those with COPD had mean % predicted FEV1 of 72.3 (SD 16.4) which was significantly lower (p<0.0001) than the men without COPD (95.5 SD 15.0). Men with COPD had fewer teeth (p=0.0042), higher CAL (p= 0.012) and were more likely to report having a denture (p= 0.004). The unadjusted OR for men with fewer teeth to be identified with COPD was 1.45 [95% CI 1.09-1.93], p=0.011; with higher CAL OR = 1.43 [CI 1.08-1.88], p=0.012 and having a denture OR = 1.50 [CI 1.14-1.97], p=0.0041. After adjusting for age, smoking, BMI, education status and pattern of dental attendance only having a denture remained significant with OR= 1.51 [1.05-2.16] p=0.026.
Conclusions: In a representative sample of dentate men in Northern Ireland, having a denture was an independent risk indicator of COPD.
