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.	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.
