Introduction and Objective: Periodontitis is the one of most common chronic inflammatory diseases of the oral cavity. Periodontal disease (PD) concerns mainly adults; however, it is now increasingly seen in adolescents. The mechanism responsible for the higher prevalence of periodontal among young adults may be associated with the changes in lifestyle. Awareness of the role of proper oral hygiene and a healthy lifestyle is therefore essential for the prevention of periodontal disease in young people. The aim of the study was to assess the prevalence and severity of periodontal disease among 18-year-old young adults from Lublin Province in eastern Poland. Material and Methods: The study group included 75 adolescents aged 18 years – 50 urban and 25 rural. Periodontal status was assessed on the basis of the CPI (Community Periodontal Index). Results: The results obtained showed that clinically healthy periodontium was found only in 26.66% of the study population. 73.34% of adolescents had periodontal problems. Healthy periodontium was observed more frequently among rural residents than among urban residents Conclusions: The data show that 73.4% of young adults needs to take preventive or treatment actions for periodontal diseases. It could be used as a marker for an increased risk of PD in adults.
