[Cyclosporine-induced gingival hyperplasia in renal transplant patients].

Cyclosporine-induced gingival hyperplasia was investigated in a clinical study of 80 renal transplant patients. 34% of the patients exhibited at least mild gingival hyperplasia in the anterior, and 9% presented this finding also in the posterior region. No direct correlation was found between the oral dose or the whole blood concentration of cyclosporine and the presence of gingival overgrowth. Young and female patients were at a significantly greater risk of developing cyclosporine-induced gingival hyperplasia than the other patients. The presence of dental plaque or gingival inflammation was not found to be related to the incidence of gingival hyperplasia.
