The association of denture wearing with reduced lung function and increased airflow limitation in 58-72 year old men.

Objective: To investigate the association between denture wearing and airflow limitation in men in Northern Ireland enrolled in the Prospective Epidemiological Study of Myocardial Infarction (PRIME) study.

Methods: A case-control design was used to study partially dentate men. Cases were men aged 58-72 years who were confirmed as denture wearers.

Subgingival microbial diversity and respiratory decline: A cross-sectional study.

Aim: To investigate whether there is an association between subgingival microbial diversity and reduced respiratory function.

Materials And Methods: A group of dentate 58-72-year-old men in Northern Ireland had a comprehensive periodontal examination including subgingival plaque sampling. DNA was extracted from plaque samples and the V1-V3 regions of the 16S rRNA gene were analysed by high-throughput sequencing and a microbial diversity index (MDI) was derived.
