1. Cardiovascular disease: Studies (including the S3 guideline "Treatment of Stage I–III Periodontitis" by DG PARO/DGZMK 2020, and the EFP/WHF consensus 2020) link periodontitis to an increased risk of arteriosclerosis (hardening of the arteries), heart attack and stroke. It is thought that bacteria released into the bloodstream attack the vessel walls, contributing to plaque formation and arterial stiffening.
2. Diabetes: There is a two-way relationship between periodontitis and diabetes. People with poorly controlled diabetes have an increased risk of periodontitis, as high blood sugar levels weaken the immune system and thereby reduce the body's defences in the mouth.
3. Respiratory conditions: Patients with periodontitis face an increased risk of bacteria present in the oral cavity reaching the lungs. Older people and people with reduced lung function are particularly at risk.
4. Rheumatoid arthritis: There is evidence that the bacterial pathogens involved in periodontitis play a role in triggering and worsening this condition.
5. Pregnancy complications: Periodontitis is associated with an increased risk of premature birth and low birth weight.
Close cooperation between dentists and general practitioners is particularly important.
