For periodontitis evaluation, what interval is recommended?

• A. 1 month
• B. 3-6 months
• C. 9-12 months
• D. 6-9 months

Answer: (B)

Regular monitoring of periodontal disease is essential to catch changes early, assess healing after therapy, and adjust the treatment plan. After completing initial periodontal therapy and stabilization, the recommended re-evaluation interval is every 3-6 months. This cadence reflects how quickly plaque and calculus can reform and how periodontal health can change between visits, allowing timely intervention before pockets deepen or inflammation worsens. In practice, very well-controlled cases with good home care might be spaced toward six months, while animals with more severe disease or ongoing plaque accumulation may need visits every three months. Shorter than three months is usually reserved for active disease management or high-risk patients, and longer than six months increases the risk of progression going unnoticed.
