BACKGROUND: Periodontitis shares several clinical and pathogenic characteristics with chronic arthritis, and there is some degree of coexistence. The aims of this study were to elucidate whether patients with localized aggressive periodontitis (LAgP), generalized aggressive periodontitis (GAgP), juvenile idiopathic arthritis (JIA), and rheumatoid arthritis (RA) share periodontal and hematological characteristics distinguishing them from individuals free of diseases. METHODS: The study population consisted of white adults (or=4 mm, CAL>or=2 mm, and ABL>or=2 mm compared to controls. The percentage of sites with CAL>or=2 mm significantly correlated with the levels of IgM-RF and IgA-RF. Missing teeth in JIA and RA patients were not lost due to periodontitis. Patients with GAgP showed higher levels of leukocytes, including neutrophils, and CRP compared to controls. In part, JIA and RA patients showed similar results. CONCLUSIONS: Young adults with RA may develop periodontal destruction, and these patients require professional attention. Both differences and similarities in periodontal and hematological variables were seen in individuals with periodontitis, JIA, and RA.
