| 概要≠ | The DMFT (Decayed, Missing due to caries, Filled) Index is a standardized epidemiological measure of dental caries experience in permanent dentition. Developed by Klein, Palmer, and Knutson in 1938, it quantifies the number of permanent teeth that are decayed, missing due to caries, or filled due to caries. The DMFT Index remains the most widely used caries index globally, enabling comparison of oral health across populations and tracking disease burden over time. | 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. |
