[Gingival overgrowth in patients under cyclosporin-A treatment. A clinical study]

The aim of the present study was to investigate possible background factors causing gingival overgrowth (GO) among transplant patients treated with cyclosporine-A (Cy-A). Nineteen subjects were evaluated with regard to Cy-A therapy including: whole blood concentration, oral dosage, duration of therapy, cumulative exposure factor. Periodontal condition was assessed using Plaque Index, probing depth and probing attachment level. GO was assessed on plaster study models by a semiquantitative method. The occurrence of GO was 88%, with a total 35.9% of gingival sites presenting overgrowth. Statistical analysis showed no correlation between GO score on one hand, oral dosage, exposure factor and plaque score on the other. ANOVA revealed a significant relationship between GO score and percentage of affected sites.
