An advanced periodontal disease case should be evaluated how often?

• A. 2 weeks
• B. 2 months
• C. 1 month
• D. 4 months

Answer: (C)

Frequent rechecks are essential when periodontal disease is advanced to catch progression early, guide ongoing therapy, and confirm healing. Monitoring about every four weeks (monthly) lets you reassess attachment levels, probing depths, gingival inflammation, tooth mobility, and plaque control, and then adjust the treatment plan or home care as needed. This interval is short enough to detect changes and prevent further loss of support, yet practical for ongoing management.

If you go longer than a month, key changes can slip by, increasing the risk of additional bone loss or tooth loss. Shorter than a month is usually unnecessary once healing is underway and stability is achieved, though unstable cases may require closer follow-up.
