A patient has lower anterior recession adjacent to a prominent labial frenum. Which of the following is NOT a cause of the recession?
Show answer and explanation
Correct answer: C. Gingivitis
- A. Incorrect — frenum pull IS a cause. A high/prominent labial frenum pulls on marginal gingiva, contributing to recession.
- B. Incorrect — thin biotype IS a cause. Thin alveolar bone with minimal attached gingiva predisposes to recession.
- C. Correct. GINGIVITIS is NOT typically a direct cause of gingival recession. Gingivitis causes inflammation and gingival ENLARGEMENT (edema, increased probing depth) — NOT recession. Recession results from mechanical forces, anatomical factors, or destructive periodontitis — not simple gingivitis.
- D. Incorrect — traumatic brushing IS a cause. Horizontal scrubbing with hard bristles is one of the most common causes of buccal recession.
