Clinical and microbiological analysis of periodontally diseased sites after renal transplant.

This study compared the clinical and microbiological status of periodontally diseased sites in 42 patients who had a renal transplant and were undergoing immunosuppressive therapy (21 taking azathioprin and corticosteroids [Az-C] and 21 taking cyclosporin-A [Cy-A] with those of 21 systemically healthy matched controls. Probing pocket depth (PPD), bleeding on probing (BOP) and gingival hyperplasia (GH) were measured at 339 sites. Subgingival plaque samples were analyzed for the presence of Porphyromonas gingivalis, Treponema denticola and/or Bacteroides forsythus using the BANA test. Our findings suggest that immunosuppressed patients showed significantly less inflammation and fewer putative anaerobic pathogens using the BANA test, and that patients undergoing therapy with cyclosporin-A have a higher frequency of sites with gingival hyperplasia when compared with patients medicated with azathioprin or corticosteroids.
