Objective: The main purpose of this study was to determine the status of oral health in young people between 12 and 20 years. The examined people were from the Dalmatian region, especially Split. The main goal was to gather the differences in oral health status in different regions in Croatia, countries in the region and some developed countries in the world. Material and methods: Panoramic radiographies were collected from the department of orthodontics of the “ Dental Poliklinika Split”. 100 radiographs from adolescents between the age of 12 and 20 were used to determine their so-called DMFT-index (decay, missing, filled teeth). Results: The average DMFT-index was 5,28 + 3,71. The study was performed based on 100 radiographs of juveniles from the region around Split, the so-called “Splitsko-Dalmatinska“ county, taken in the department of orthodontics of “Dental clinic Split”. The highest DMFT-Index was found at the age of 17 and the lowest in individuals at the ages of 16 and 13. According to the DMFT, the amount of male and female subjects as well as the amount of stoppings was the same. The tooth showing the most caries was the first molar on the right side in the mandibular region. In contrast to this, the tooth showing the lowest caries prevalence was the first molar on the left side of the maxilla. The tooth with the highest prevalence of stopping was the first molar on the right side of the maxilla and the one with the least was the first molar on the right side of the mandible. The least extracted tooth was the first molar of the left side of the mandible, the most extracted were the first molars on the right side. Conclusion: These results lead to the conclusion that there is a necessity to monitor the oral health in the generation from young children to juveniles in Croatia. From this research which was focusing especially on the region around Split, it can be concluded that the oral health of adolescents is not satisfactory, and that there is a medical necessity to implement modern and preventive programs and measures in primary health systems, but especially to promote oral health in this age group.
