Abstract
Smoking is known to be a causative factor of periodontal disease in addition to drinking alcohol. However, studies on microorganisms in oral cavity according to smoking status are currently very poor. In this study, 30 smokers and 30 nonsmokers were selected for university students. It was statistically significant that Streptococcus mutans, Prevotella intermedia were detected more frequently in smokers with 30% compared to non-smokers with 7%, and was detected in subjects that engaged in tooth brushing fewer than three times a day with 20%(p<0.05). P. intermedia was significant in that more bacteria were detected in smokers than in non-smokers (p<0.05). As continuous smoking directly stimulates the oral cavity, bacteria that can cause oral disease may appear more dominant than in non-smokers. Furthermore, it is expected that it will have a positive effect on students' smoking cessation.
