D rug-induced gingival overgrowth (DIGO) is an unwanted adverse effect of some drugs such as immunosuppressant (cyclosporine), anticonvulsant (phenytoin), and calcium channel blockers(nifedipine). This can be a cosmetic problem, interfere with eating an speech, impede effective tooth cleaning or force the teeth out of aligment. Management of DIGO includes non surgical and surgical treatment including neither drug substitution nor drug combination. Although surgery remains the general option for treating gingival enlargement, surgery can cause post operative discomforts and unwanted side effects such as bleeding and trauma. Non surgical treatment including neither drug substitution nor drug combination has proven either to prevent this unwanted effect, reduces the incidence of its recurrence, or even vanish the gingival enlargement itself. This is an advantage for patiengs with trauma background.
