For gingivitis, what is a plausible reevaluation interval?

• A. 1 month
• B. 3-4 months
• C. 6 months
• D. 9 months

Answer: (C)

Gingivitis is reversible with effective plaque control, so the recheck interval should be spaced to confirm healing and ensure ongoing control. After initial treatment and establishing good home care, a six-month recheck provides a practical balance: you can verify that inflammation has resolved, assess how well plaque control is working, and reinforce instructions to the owner. Rechecks that are too frequent (monthly) aren’t usually needed once inflammation has stabilized, while waiting longer (nine months) risks missing early recurrence or progression to more serious periodontal disease. If disease is more active or owner compliance is uncertain, shorter intervals like every 3–4 months may be warranted, but six months is a reasonable standard for gingivitis under stable management.
