In a recent study led by Vanessa Grubs at University of California, San Francisco, it was found that participants with severe periodontal disease developed chronic kidney disease (CKD) at four times the rate at those without severe periodontal disease.
Periodontitis disproportionately affects African Americans, and it has also been implicated as a potential risk factor for CKD. For the study, researchers analysed 699 African American adults with normal kidney function, who underwent complete dental examinations.
During an average follow-up of 4.8 years, there were 21 new CKD cases. Participants with severe periodontal disease had a 4.2-fold greater incidence of CKD compared with those without periodontal disease.
Dr Grubbs said: “Because periodontal disease is common and can be prevented and treated, targeting it may be an important path towards reducing existing racial and ethnic disparities in chronic and end-stage kidney disease.”
