[Cyclosporin and gingival hyperplasia: apropos of three clinical cases]

Three cases of extensive gingival hyperplasia associated with long-term cyclosporine therapy are presented. Following periodontal therapy, the patients have been maintained well for 15 months. The authors attempt to explain the etio-pathology of gingival hyperplasia following the use of immunosuppressant drugs. They stress the need for better understanding of this phenomenon among physicians who prescribe cyclosporine.
