The purpose of this study was to recognize the risk of poor oral hygiene from second-hand smoking as well as first-hand smoking. This study analyzed the oral hygiene by measuring PHP index of 211 male technical high school students according to smoking conditions. PHP index was calcualted by QLF-D and tooth surface disclosing method. 1. PHP index of first-hand smokers was significantly higher than that of non first-hand smokers(p<0.01). 2. PHP index of second-hand smokers was significantly higher than that of non second-hand smokers(p<0.05). 3. PHP index was significantly different according to smoking conditions. The index of first-hand smokers who had exposed to second-hand smoking was the highest while the index of non smokers was the lowest(p<0.01). Given the findings of the study, smoking conditions could affect the oral hygiene of youth. Especially even involuntary smoking influences the oral hygiene of youth.
