Résumé	The Gingival Index (GI), also known as the Loe-Silness Index, is a standardized clinician-rated assessment tool for measuring the severity of gingival inflammation and periodontal disease. Developed by Loe and Silness in 1963, the GI remains the gold standard for quantifying gum inflammation in clinical research and practice. It grades inflammation on a 0-3 ordinal scale based on visual appearance and bleeding response, enabling objective assessment of periodontal health, monitoring of periodontal disease progression, and evaluation of treatment efficacy.	The Caries-risk Assessment Tool (CAT), also known as Caries Management by Risk Assessment (CAMBRA), is a systematic framework for evaluating a patient's risk of developing dental caries (cavities). Developed by Featherstone and endorsed by the American Academy of Pediatric Dentistry (AAPD), American Dental Association (ADA), and International Association of Dental Research, the CAT stratifies patients into low, moderate, or high caries-risk categories based on clinical and behavioral factors. Risk assessment guides preventive interventions, enabling individualized caries management and efficient resource allocation.
