Effects of Mobile-Based AI-Enhanced Health Counseling on Protection Motivation, Self-Care Behaviors, and Periodontal Treatment Outcomes in Patients With Periodontitis: Randomized Controlled Trial

AI-assisted monitoring improved self-care behaviors, plaque control, and periodontal clinical outcomes. Although PM constructs (threat appraisal and coping appraisal) improved similarly across all groups, the greater behavioral and clinical improvements observed in the AI-assisted groups highlight the potential of AI monitoring as an effective tool to enhance periodontal care. Incorporating AI technologies into routine practice may empower patients to take a more active role in managing their oral health and support more effective, patient-centered periodontal therapy.
