    Caries Risk Factors

    • Fewer than 15 teeth is not a recognized risk factor for caries, while less than 9 present teeth indicates high risk.

    Chronic Gingival Inflammation

    • Signs include tough, fibrous gingiva and blunted interdental papilla.

    PSR (Periodontal Screening and Reporting)
