Clean teeth can hold off arthritis: Scientists discover link between gum disease bacteria and early onset of the condition

  • Link between gum disease bacterium and onset of rheumatoid arthritis
  • Bacterium produces enzyme which reacts with residue of certain proteins
  • Body recognises these proteins as intruders, leading to an immune attack

Brushing your teeth well could help prevent arthritis, scientists claim.

Researchers found a link between the bacterium responsible for gum disease and earlier onset of rheumatoid arthritis, as well as faster progression and greater severity of the condition.

The bacterium produces an enzyme which reacts with the residue of certain proteins.

The body recognises these proteins as intruders, leading to an immune attack, the researchers from the University of Louisville’s School of Dentistry in Kentucky said.

In arthritis patients, the subsequent result is chronic inflammation responsible for bone and cartilage destruction within the joints.

Previous studies have indicated that gum disease is at least two times  more prevalent in rheumatoid arthritis patients.

The bacterium, Porphyromonas gingivalis, produces a unique enzyme, peptidylarginine deiminanse (PAD).

 

They discovered that PAD changes residues of certain proteins into citrulline, and the body recognises these proteins as intruders, leading to an immune attack. 

In rheumatoid arthritis patients, the subsequent result is chronic inflammation responsible for bone and cartilage destruction within the joints.

Researcher Dr Jan Potempa from the University of Louisville School of Dentistry Oral Health and Systemic Diseases said: 'Taken together, our results suggest that bacterial PAD may constitute the mechanistic link between P. gingivalis periodontal infection and rheumatoid arthritis, but this ground-breaking conclusion will need to be verified with further research.'

Dr Potempa and his team studied another oral bacterium, Prevotella intermedia for the same affect, but learned it did not produce PAD or the subsequent effects.

Writing in the study, published in PLOS Pathogens, Dr Potempa said he is hopeful these findings will shed new light on the treatment and prevention of rheumatoid arthritis.

Studies indicate that compared to the general population, people with periodontal disease have an increased prevalence of rheumatoid arthritis and periodontal disease is at least two times more prevalent in rheumatoid arthritis patients. 

Other research has shown that a P. gingivalis infection in the mouth will precede rheumatoid arthritis and the bacterium is the likely culprit for onset and continuation of the autoimmune inflammatory responses that occur in the disease.
