How do you calculate a DMFS valieor index?

The DMFS index, which stands for Decayed, Missing, and Filled Surfaces, is calculated by assessing the number of decayed surfaces, missing surfaces, and filled surfaces in a person's teeth. Each tooth has multiple surfaces, and you tally the total number of affected surfaces across all teeth. The formula is DMFS = D + M + F, where D is the total number of decayed surfaces, M is the total number of missing surfaces, and F is the total number of filled surfaces. This index provides a comprehensive measure of dental caries and treatment needs in a population.
