What is the appropriate FIRST step in managing this enlargement?

Patient case: Generalized gingival enlargement in a patient on multiple medications

Patient: Male, 45 years old

Chief Complaint: “My gums are growing over my teeth.”

Background: Epilepsy controlled on phenytoin for nine years. Hypertension on amlodipine. Renal transplant six years ago, on ciclosporin. Irregular brushing, no interdental cleaning.

Vital Signs: BP 136/86 mmHg · HR 76 bpm · T 98.2°F

Findings: Firm, pale, stippled gingival enlargement beginning at the interdental papillae and extending to cover up to a third of several clinical crowns, most marked anteriorly and on the labial surfaces. Heavy plaque and calculus. No ulceration, no fever, no lymphadenopathy.

  1. Gingivectomy of all affected sextants
  2. Rigorous plaque control with scaling and root planing, alongside liaison with his physicians about substituting the causative drugs
  3. Apically positioned flap surgery with osseous recontouring
  4. A course of systemic metronidazole
Show answer and explanation

Correct answer: B. Rigorous plaque control with scaling and root planing, alongside liaison with his physicians about substituting the causative drugs

  • A. Gingivectomy performed while plaque control remains poor and the drugs continue unchanged has a high recurrence rate. Surgery may still be needed, but it is the SECOND step, not the first.
  • B. CORRECT. PLAQUE IS THE MODIFYING FACTOR. The drug creates susceptibility, but the degree of enlargement tracks the inflammatory burden — which is why meticulous scaling, root planing and oral hygiene instruction produce genuine reduction on their own. In parallel, consult the prescribing physicians: valproate or levetiracetam can replace phenytoin, a non-dihydropyridine antihypertensive can replace amlodipine, and tacrolimus causes far less enlargement than ciclosporin. Re-evaluate after resolution of inflammation and only then decide whether residual fibrous tissue needs excision.
  • C. Apically positioned flap surgery with osseous recontouring addresses pocket elimination in periodontitis with bony defects. This patient has pseudopockets from enlarged tissue, not intrabony defects.
  • D. Metronidazole treats anaerobic infection. Some studies report modest reduction in ciclosporin-associated enlargement, but it is adjunctive at best and is not the first step.

Note: Sequence: plaque control and drug substitution first; re-evaluate at six to eight weeks; then excise residual fibrous tissue by gingivectomy for accessible enlargement, or by an internal-bevel flap where attached gingiva is limited or bone must be exposed. Without ongoing plaque control after surgery, it recurs.
