Objectives: This study is aimed to evaluate the correlation between self-reported oral health and caries experience, and to find out factors that affect perceived oral health status and treatment need in Korean male soldiers aged 18 to 24. Methods: The cross-sectional oral health examination and questionnaire survey about the attitude of oral health were conducted (n=2,436). The survey contained self-reported oral health status, self-reported dental treatment need and associated factors. Results: Caries experience like DMFT, DT, FT, and MT indices were significantly different by selfreported oral health status, as well as the self-perceived dental treatment need (P<0.005). Experience rates of ``tooth pain``, ``periodontal pain``, ``tooth hypersensitiveness``, ``gingival bleeding``, ``tooth cavity``, ``oral malodor``, ``need prophylaxis``, ``former dental treatment``, ``smoking`` and ``scaling`` were different by selfreported oral health status and self-perceived dental treatment need (P<0.05). Conclusions: Subjective oral health perception reflected objective oral health status and other oral health related factors.
