Mary Ann Moon writing in Rheumatology News described a study comparing 31 patients with new-onset rheumatoid arthritis (RA), 34 patients with chronic RA, and 18 healthy controls.The study examined the relationship between bad dentition and rheumatoid arthritis.
The prevalence of severe periodontal disease was 75 % in patients with new-onset RA… just as much as the prevalence with long-standing RA and much higher than the prevalence in healthy controls (39%). The culprit?
Porphyromonas species bacteria.
The association between periodontal disease and RA has been written about a lot. This should be added to genetics and smoking as big risk factors for RA.
