Abstract

Aim: To assess the prevalence and variables associated with gingival overgrowth (GO) in renal transplant recipients medicated with cyclosporine (CsA), tacrolimus (Tcr), or sirolimus (Sir).

Materials and Methods: One hundred and thirty-five eligible subjects were divided in CsA, Tcr, and Sir groups comprising 45 subjects each. GO was visually assessed and subjects were assigned as GO+ or GO− in a post hoc definition. Saliva samples were collected and the presence of periodontal pathogens was assessed through polymerase chain reaction. Variables of interest were compared between GO+ and GO− subjects through univariate and multivariate analysis.

Results: Prevalence of GO was of 60.0% for CsA, 28.9% for Tcr, and 15.6% for Sir groups. Within the CsA group, GO was associated with papillary bleeding index (p=0.001); within the Tcr group, GO was associated with CsA previous use (p=0.013), and calcium channel blockers (CCB) use (p=0.003); within the Sir group, GO was associated with papillary bleeding index (p=0.018), and CCB use (p=0.020). A higher frequency of Tannerella forsythia was observed among GO+ subjects medicated with Tcr.

Conclusion: Pharmacological and periodontal variables were associated with GO in different immunosuppressive regimens. Integration between the medical and the dental team may be an important approach in the post-transplant maintenance routine.
