The purpose of this study, in order to examine the relation between college students' oral care behaviors, dietary habits, academic stress and self-perceived halitosis. A structured anonymous self-administered questionnaire was administered to 595 college students from May 21 to Jun 4, 2020. The collected data were analyzed by chi-square test, t-test, one-way ANOVA, Pearson's correlation analysis using SPSS 23.0 program. As a result, males, the students majoring in engineering(natural science), smokers, those smoking more than 16 cigarettes a day on average, and those without the experience of oral health education were found to have a meaningfully higher level of self-perceived halitosis than those with other variables (p<0.05). Moreover, there were meaningful differences in the self-perceived halitosis depending on oral health status, times of tooth brushing, number of tooth brushing, and the replacement of a toothbrush (p <0.05). Therefore, for the reduction or prevention of halitosis, a program that can be applied earlier should be developed and education for adaptation is necessary.
