Objective: The purpose of the study is to investigate the relationship between oral health behaviors and Self- perceived oral health in Korean adolescents. Methods: The survey data was extracted from Korea National Health and Nutrition Examination Survey (KNHANES) VI-3 (2015). The subjects of this study were 488 adolescent samples aged 13 to 18 years old. The data about gender, age and use of oral care supplies were analyzed without conversion. SPSS version 22.0 was used for the statistical analysis. Results: The results were significant differences in the self-perceived oral health status according to the BMI, tooth brushing frequency, use of dental floss and use of mouthwash (p<0.05). Multiple logistic regression analysis revealed that the tooth brushing frequency and the use of mouthwash were found to significantly affect the self-perceived oral health status (p<0.05). Conclusion: When the number of brushing times is large and oral hygiene auxiliary products are used, the interest in oral care is high and the oral hygiene is perceived as well because it is well known and practiced. In adolescence, basic and systematic oral health care education should be expanded and effective oral health care programs should be developed through diverse and interesting media.
