The purpose of the present study was to find out the prevalence of dental caries among adolescent and adult inhabitants of Ljubljana, Yugoslavia. 1692 randomly selected subjects were examined in the age groups 15, 25, 35, 45, 55 and 65 years. Of all subjects there were 4.9% edentulous. In this research DMFT index was used in 1609 dentate persons. 28 teeth were considered. The prevalence of dental caries is very high among the citizens of Ljubljana, already at the age of 15 there is 98.3%. Mean DMFT values were found to increase with age, from 9.8 teeth at the age of 15 to 22.9 teeth at the age of 65. The mean number of missing teeth (M) increases with age as well, from 0.5 tooth at the age of 15 to 14.9 teeth at the age of 65. The mean number of decayed teeth (D) and filled teeth (F) decreases after the age of 35 due to greater number of missing teeth. Women have more decayed teeth in the age of 15 and 25, they also have more missing teeth after the age of 25, women have in all age groups more filled teeth and a higher mean DMFT values in comparison with men. Immigrant inhabitants had in majority of aged groups more decayed and more missing teeth, less filled teeth and a lower mean DMFT values in comparison with native inhabitants. The biggest difference was in the age group of 25, where immigrant men were the worst group. On the other hand immigrant inhabitants had greater number of healthy teeth in all aged groups in comparison with the native inhabitants.
