For advanced periodontal disease evaluation, how often should reevaluation occur?

• A. Every 2 weeks
• B. Every 2 months
• C. Every 3 months
• D. Every 1 month

Answer: (D)

Advanced periodontal disease can progress quickly, so reevaluation frequency is crucial. After active therapy, tissues continue to change as inflammation resolves, attachment levels stabilize or worsen, and the patient’s owner implements home care. Checking the patient every month allows you to track healing, reassess pocket depths and gingival health, and catch any signs of treatment failure or new progression early. It also provides regular opportunities to reinforce owner instructions, adjust plans (such as additional debridement, changes in antimicrobial strategy, or extraction decisions), and ensure that maintenance steps are effective.

Waiting longer, like two weeks or a few months, can miss early changes in the disease state, leading to unnoticed progression or delayed interventions. Monthly reevaluation strikes a practical balance, supporting timely adjustments during the active phase of periodontal therapy in pets with advanced disease.
