Objectives: This study attempted to provide basic data necessary for a prevention promotion program for oral health management in college students. Methods: This study investigated general characteristics and subjective periodontal health status using a structured questionnaire and examined the distribution of bacteria related to periodontal disease in oral cavity by real-time PCR in subjects composed of 57 male and female college students. Results: It was statistically significant that P. gingivalis was detected more frequently in smokers with 25% compared to non-smokers with 6.1%, not detected in subjects that engaged in tooth brushing more than three times a day, and was detected in subjects that engaged in tooth brushing fewer than three times a day with 21.1%. Pathogens in saliva had significant correlations with each other (p<0.05, p<0.01, p<0.001). P. gingivalis showed positive correlations with T. forsythia, T. denticola, P. intermedia, and A. actinomycetemocmitans, and T. forsythia with P. intermedia, and A. actinomycetemocmitans. P. intermedia had a positive correlation with A. actinomycetemocmitans, and F. nucleatum with P. intermedia. Conclusions: Bacteria related to periodontal disease in oral cavities in college students were distributed in various ways, and smoking and the frequency of daily toothbrushing were found to be risk factors for the detection of bacteria.
