Aim. To determine the incidence of dental caries among a representative group of children at the age between 6 and 18 years from Sofia. Materials and Methods. The study includes 445 children who were assessed the prevalence of dental caries index of Klein, Palmer& Knutson (1938) - DMFT, taking into account the total number of teeth that are with caries (D), missing (M) or with restoration (F) for each individual. Results. The results showed that 67 % aged between 6 and 12 years, and 70 % of 13-18 years have been diagnosed with caries. The value of the index DMFT in both groups is from 1.88 to 3.6. Free from the caries are 33 % and 30 % from both groups. Conclusion. The number of children free of caries is still far from the number of those in the developed countries.
