Objectives : The purpose of this study was to examine actual conditions of smoking and alcohol drinking behaviors among high school students, so that it could recognize possible harmful effects of smoking on oral health and could give positive motivations for students to quit smoking and drinking. Methods : This research was based on self-filling survey which 1,385 high school students in metropolitan area in Korea from September 5 to October 28, 2011. Surveyed data were analyzed by descriptive statistics, ${\chi}^2$-test and logistic analysis using SPSS WIN 12.0 program and its signification level was 0.05. Results : 1. As for smoking rate and drinking rate, boy students accounted for 11.6% and 25.4%, thereby having been higher than girl students(p<.001). It was the highest in over 180 cm(16.0%, 35.0%, p<.001) for height, in 60-under 70 kg for weight(13.4%, 23.5%, p<.001), and in a case of profession for mother's job(13.8%, 28.4%, p<.005). 2. The perceived oral symptoms had relationship with the less than 10 cigarettes of smoke (OR=2.41; 95% CI:1.31-4.41), more than 11 cigarettes of smoke (OR=3.16; 95% CI:1.42-7.00) and more than 1 bottle of alcohol (OR=1.75; 95% CI:1.00-3.06). Conclusions : This result implies that adolescents' smoking and drinking have correlation with oral health status, which makes uncomfortable sense felt given chewing along with the pain in teeth and gum. Based on the above findings, a school or community needs to reinforce education for preventing smoking and drinking and to offer environment available for practicing anti-smoking and anti-drinking plan, in order to reduce adolescents' smoking and drinking.

The present study was performed to investigate the relationship between the salivary flow rate and the interpretation results of salivary scan in the patients with dry mouth. Twenty-five patients with dry mouth who visited the Dept. of Oral Medicine & Oral Diagnosis, Seoul National University Dental Hospital, were included. The unstimulated whole salivary flow rate was determined by the spitting method and the stimulated whole salivary flow rate was measured with gum-base chewing. Salivary scan was performed after the infusion of $^{99m}technetium$ pertechnetate(Tc) and interpreted. The obtained results were as follows: 1. The unstimulated and stimulated whole salivary flow rate were significantly decreased compared to normal value, which reflected the extensive destruction of salivary gland function in the patients with dry mouth. 2. The unstimulated and stimulated whole salivary flow rate were decreased in the group with decreased function in salivary scan compared with the group with normal function in salivary scan. However, there was no statistical significance between groups. 3. The difference between the stimulated and unstimulated whole salivary flow rates was greater in the group with normal function in salivary scan compared with the group with decreased function in salivary scan. 4. There was significant positive correlation between the stimulated and unstimulated whole salivary flow rates. The level of correlation was higher in the group with decreased function in salivary scan than the group with normal function in salivary scan. Collectively, these data suggested that salivary scan had the limited value. The comprehensive evaluation including history taking, clinical examination, clinical laboratory as well as the measurement of salivary flow rate are need for patients with dry mouth.

The purpose of this study was to examine the oral health awareness and oral health care of health-related and health-unrelated majors in an attempt to stress the importance of oral health education and boost the efficiency of oral health care. The subjects in this study were 363 college students. Out of the selected students, 174 were health-related majors, and 189 weren't. After a survey was conducted, the collected data were analyzed for the purpose of comparison, and the following findings were given: 1. Concerning daily mean toothbrushing frequency, the largest number of the male students who accounted for 55.2 percent brushed their teeth once a day on average, and the greatest number of the female students who represented 52.9 percent did that twice a day. As for the influence of their major, the largest group of the health-related majors who numbered 89(51.1%) brushed their teeth twice a day, and the greatest group of the health-unrelated majors who numbered 93(49.2%) did that once a day. The gaps between them were statistically significant(p<0.05). 2. As to the length of toothbrushing time by gender, it took more than two or three minutes for the largest groups of the male and female students that respectively numbered 96(76.8%) and 184(77.3%) to do toothbrushing(p<0.01). The greatest groups of the male and female students that respectively numbered 72(57.6%) and 183(76.9%) brushed their teeth after meals. 3. In regard to oral hygiene supplies, the largest groups of the health-related and health-unrelated majors that respectively numbered 78(44.8%) and 115(60.8%) had chewing gum and candy with them. As to the use of oral hygiene supplies, 99 health-related majors(56.9%) and 133 health-unrelated majors(70.4%) didn't put oral hygiene supplies to use. Thus, the use of oral hygiene supplies was statistically less common among the health-unrelated majors, and the gap between the two was significant(p<0.01). 4. As for health-related concern by gender, the largest group of the male students that numbered 56(44.8%) showed the most interest in preventing dental caries, and the greatest group of the female students that numbered 103(43.3%) were most concerned about tooth whitening. The gap between the male and female students was statistically significant(p<0.05), but the track of their major made no statistically significant difference to that. 5. Regarding the experience and awareness of scaling, the largest number of the students never got their teeth scaled regardless of gender and major, and the greatest group didn't care about scaling irrespective of gender and major, either, though they considered it advisable to do.
