OBJECTIVE: To investigate whether there was an association between chronic periodontitis (CP) and reduced respiratory function.
METHODS: A group of dentate 58- to 72-year-old men in Northern Ireland had a comprehensive periodontal examination. Parallel to the periodontal examination, participants completed questionnaires gathering information on their medical history, social circumstances, demographic background and tobacco use. A physical examination assessed anthropometric measures. Fasting blood samples were obtained and analysed for high-sensitivity C-reactive protein (hs-CRP). Spirometry measures were performed using a wedge bellows spirometer (Vitalograph S Model). The primary outcome variable of interest was the percentage predicted forced expiratory volume in one-second (% predicted FEV1 ). Analysis included multiple linear regression with adjustment for various confounders and a regression-based mediation analysis.
RESULTS: A total of 1,380 men were included in the analysis. The mean age was 63.7 years (SD 3.0). Multiple linear regression analysis showed that a doubling in mean clinical attachment loss (CAL) equated to a -3.33% (95% CI: -4.80, -1.86), p < 0.001 change in % predicted FEV1 after adjustment for all other potential confounding variables. Systemic inflammation, as measured by hs-CRP, only accounted for a minor mediating pathway effect (9%).
CONCLUSIONS: In this homogenous group of dentate men, CP was significantly associated with a reduced respiratory function.
