Abstract

Objectives: The purpose of this study was to evaluate the periodontal status of adolescents aged 15 years in Jinju city.Methods: The study subjects were 506 adolescents aged 15 years in Jinju city. We investigated the prevalence and severity of periodontal disease using the Community Periodontal Index (CPI) recommended by the WHO. Data on the frequency of daily tooth-brushing were collected through self-reported questionnaires. The information obtained on both the periodontal health status and frequency of daily toothbrushing of adolescents in Jinju city was compared with the data from the 6th Korea National Health and Nutrition Examination Survey 2013-2015 (KNHANES-VI). The software utilized in the analysis was SPSS version 23. Statistical significance was set at P<0.05.Results: The rate of healthy periodontal status in Jinju city was lower compared to KNHANES-VI (57.7% versus 63.7%). The rate of gingival bleeding in Jinju city and KNHANES-VI was 11.3% and 10.8%, respectively. The rate of calculus in Jinju city and KNHANES-VI was 31.0% and 25.6%, respectively. The rates of gingival bleeding and calculus were not significantly different between Jinju city and KNHANES-VI. The healthy periodontal segments in Jinju city were more than those in KNHANES-VI (5.43 versus 5.25). The bleeding periodontal segments in Jinju city were less than those in KNHANES-VI (0.25 versus 0.45). However, the periodontal segments with calculus in Jinju city were not significantly different from those of KNHANES-VI (0.31 versus 0.30). The frequency of daily tooth-brushing in Jinju city was more than that in KNHANES-VI (2.67 versus 2.47).Conclusions: These findings suggest that appropriate oral health education should be widely conducted to promote periodontal health in adolescents.
