Severe gum disease is associated with impaired lung function

Copenhagen, 17 June 2022. Lung function declines with increasingly severe gum disease, according to research presented at EuroPerio10, the world’s leading congress in periodontology and implant dentistry organised by the European Federation of Periodontology (EFP) (1).

“Our study indicates a link between periodontal disease and lung function meaning that good dental hygiene may benefit both oral and respiratory health,” said study author Dr Anders Røsland of the University of Bergen, Norway. “More research is needed to evaluate causality and whether lung function can be improved with periodontal therapy.”

Previous research has found that dental cleaning including plaque removal is associated with a reduction in symptom flare-ups in patients with chronic obstructive pulmonary disease (2). This study investigated the association between lung function and periodontitis in the community-based Malmö Offspring Dental Study.

The study included 1,021 participants, of which 513 were men and 508 were women. The average age was 44.5 years. A dental check-up was performed, including X-rays and an examination of the teeth and gums. The severity of periodontitis was assessed by measuring pocket depths around the teeth and loss of attachment from the surrounding tissues. The extent of inflammation of the gums was determined from the percentage of sites showing bleeding on probing.

Moderate periodontitis was diagnosed in 289 (28%) participants and 71 (7%) had severe periodontitis. The remaining 661 (65%) were classified as no periodontitis (healthy) or mild periodontitis and acted as a comparison group. The average age of those with severe periodontitis was 55 years and 59% were men. Smoking was significantly more common in people with moderate or severe periodontitis compared with the healthy/mild group.

Lung function was assessed using spirometry, which measures the volume of air exhaled from the lungs and the flow rate of air. The researchers measured forced expiratory volume (FEV1) which is the volume of air (in litres) an individual can exhale during one second after maximal inspiration. They also measured forced vital capacity (FVC) which is the amount of air (in litres) forcibly exhaled after taking the deepest breath possible. Both FEV1 and FVC were expressed as a percentage of the predicted value for healthy people (3). The researchers also calculated the ratio of FEV1/FVC (%).

The investigators found that FEV1 and FVC (both expressed as a percent of the predicted value) and FEV1/FVC declined with increasing severity of periodontitis. In analyses adjusted for age, sex, smoking, body mass index, diabetes, and educational level, significant inverse associations were observed between lung function and severe periodontitis: compared to the healthy/mild group, those with severe periodontitis had 3.6% lower FEV1 and 2.2 lower FEV1/FVC.

Dr Røsland said: “All measures of lung function deteriorated as gum disease worsened. In addition, as gum inflammation became more widespread throughout the mouth, some of the respiratory values tended to worsen. A decline in lung function may indicate airway inflammation, possibly originating from inflamed gums and the inhalation of dental plaque, which contains bacteria. If this link between gum disease and lung function is confirmed, this could provide the rationale for periodontal treatment and oral hygiene programmes to improve oral and respiratory health.”

EFP, global benchmark in periodontology

The European Federation of Periodontology (EFP, ww.efp.org) is a non-profit organisation dedicated to promoting awareness of periodontal science and the importance of gum health. Its guiding vision is “periodontal health for a better life.”

Founded in 1991, the EFP is a federation of 37 national periodontal member societies that represents more than 16,000 periodontists, dentists, researchers, and oral-health professionals from Europe and around the world. It supports evidence-based science in periodontal and oral health, and it promotes events and campaigns aimed at both professionals and the public.

The EFP organises EuroPerio, the world’s leading congress in periodontology and implant dentistry, as well as other important professional and expert events such as Perio Master Clinic and Perio Workshop. The annual Gum Health Day on May 12, organised by the EFP and its member societies, brings key messages on gum health to millions of people across the world.

The EFP also organises workshops and outreach campaigns with its partners: projects to date have covered the relationship between periodontal disease and diabetes, cardiovascular disease, and caries, as well as women’s oral health during pregnancy.

The EFP’s Journal of Clinical Periodontology is the most authoritative scientific publication in this field. The federation also publishes JCP Digest, a monthly digest of research, and the Perio Insight magazine, which features experts' views and debates.

The EFP’s work in education is also highly significant, notably its accreditation programme for postgraduate education in periodontology and implant dentistry.

The EFP has no professional or commercial agenda.
