Abstract
A formula suggested by Knutson for obtaining an age-specific estimate of mean DMFT [diseased, missing, filled teeth] in a population on the basis of the age-specific percentage of individuals with 1 or more DMFT was evaluated. A total of 149 previously collected age-specific data sets from low fluoride areas in the USA were used, and the 2 parameters K and B were estimated using the method of weighted least squares. The formula could be used with good accuracy for certain restrictions of age (5-11 yr) and percentage of individuals with 1 or more DMFT (.ltoreq. 70%).Keywords
