Tóm tắt	The Oral Hygiene Index-Simplified (OHI-S) is a rapid, non-invasive assessment tool that evaluates the amount of plaque (debris) and calculus on tooth surfaces. Developed by Greene and Vermillion in 1964, it comprises two subscales: the Debris Index-Simplified (DI-S) measuring soft deposits and the Calculus Index-Simplified (CI-S) measuring hard deposits. The OHI-S is widely used in dental research, public health surveys, and clinical practice to assess oral hygiene status and evaluate the effectiveness of preventive interventions.	Periodontal probing is a clinical assessment technique that measures the depth of gingival crevices and periodontal pockets to diagnose periodontal disease. Introduced by the American Academy of Periodontology in the mid-20th century, it remains the gold standard for assessing periodontal health status. The procedure evaluates the clinical attachment level and recession depth to identify inflammation, attachment loss, and disease progression.	Tooth mobility assessment is a clinical examination that evaluates the amount and direction of movement of a tooth when lateral force is applied. Increased tooth mobility indicates loss of periodontal support (bone loss), trauma from occlusion, or other pathology affecting tooth attachment. Systematic mobility grading enables quantification of tooth stability, guides treatment planning, and assesses prognosis in periodontal disease and post-traumatic cases.
