Drug-induced gingival hyperplasia in transplant recipients.

Gingival hyperplasia is a common occurrence in transplant recipients who are taking cyclosporine. This condition can be complicated when calcium channel blockers or phenytoin are added to the armamentarium of medications; it can be painful and may interfere with eating, speech, and appearance. Multiple mechanisms exist for gingival overgrowth. Prevention with appropriate oral hygiene appears important in controlling the inflammatory component and decreasing the severity of the overgrowth. Patients must be aware of the potential for the development of gingival hyperplasia and must follow up with regular professional cleanings. If the overgrowth persists, treatment options should be discussed between patients and their physician. Conversion from cyclosporine to tacrolimus, treatment with antibiotic therapy, and surgical excision or laser therapy are all potential therapies to consider.
