This study purposed to survey D university students' perception of kindness in their use of dental care services in an area of Gyeonggido. For this purpose, we conducted a questionnaire survey of 502 students from October 2, 2008 to March 6, 2009 and analyzed the data. Results obtained from this study are as follows. 1. Of the subjects, 71.3% were female, 67.7% were at the age of 20 or younger, and 89.2% had experience in visiting a dental clinic. Among the subjects who had experience in visiting a dental clinic, 31.1% replied that they were highly interested in oral health, and to the question on the selfperceived current oral health condition, 35.1% replied that there was something wrong in their oral health condition. 2. With regard to correlation between general characteristics and interest in oral health, 79.9% of the male subjects and 83.2% of the female ones were highly interested in oral health. According to age, interest in oral health was highest among those aged 26 or older 92.0%. 3. With regard to correlation between general characteristics and oral health condition, if the presence of dental caries or periodontal disease was considered an indicator of poor oral health, 66.0% of the male subjects and 70.9% of the female ones appeared unhealthy, 72.0% of students aged 26 or older showed satisfaction. 4. The most frequent reason for not visiting a dental clinic was 'Not sick' 34.6%, and among those who had experience, the most frequent reason for visiting was 'To get treatment of sick teeth' 63.0%. With regard to the perceived kindness of dentist and dental hygienist, 40.6% and 45.8% of the subjects, respectively, were highly satisfied. The most frequent reason for satisfaction was 'Comfortable with patient reception' 34.4% and the most frequent reason for dissatisfaction was 'Explain treatment insufficiently' 30.7%. 5. As to perceived kindness according to gender, 60.9% of the male subjects and 56.1% of the female ones were satisfied with dentist's kindness, and 66.9% and 59.6%, respectively, were satisfied with dental hygienist's kindness. According to age, 62.5% of students aged 26 or older showed satisfaction with dentist's kindness and 78.3% of them with dental hygienist's kindness. 6. As to perceived kindness according to correlation between interest in oral health and current selfperceived oral condition, the kindness of dentists(68.0%) and hygienists(67.8%) was perceived higher when interest in oral health was high and not very interested and the kindness of dentists(50.0%) and hygienists(66.78%) when selfperceived oral condition was healthy, and the difference was statistically significant (p<.022 and p<.023, respectively).

Social phobia is a mental disorder that triggers physical reactions, such as cold sweats, headaches, and panic attacks, as a result of anxiety about a particular situation. Individuals with social phobia are thought to be more sensitive to dental anxiety and may have difficulty visiting the dentist as a result. This study aimed to determine the relationship between social phobia and dental fear among college students, who are reported to have a high prevalence of social phobia. A total of 120 survey responses were analyzed. To investigate the variation in dental fear levels based on the level of social phobia, the total social phobia score was divided into two groups: 41 points or more, and 40 points or less. The disparity in dental fear scores was then analyzed using a t-test. The study found that the average score for dental fear was statistically significantly higher in the group with a total social phobia score of 41 points or more compared to the group with a total score of 40 points or less (p<0.05). Furthermore, the group that scored 41 points or higher on the social phobia scale reported experiencing symptoms such as feeling nauseous at the dentist (3.29 points), sweating upon entering the dentist (3.13 points), and feeling afraid when looking at the dentist (3.13 points). The score was high (p<0.05). Therefore, dental patients exhibiting anxiety symptoms require a comfortable treatment environment to alleviate dental fear, and safe, pain-free dental treatment techniques must be employed.

The purpose of this study was to delve into the factors associated with the oral health promotion behaviors of college students. The subjects in this study were 453 students who attended three different colleges in Gyeonggi province. After a survey was conducted, the collected data were analyzed with SPSSWIN 12.0 program. The findings of the study were as follows: 1. Concerning the basic oral health care of college students, 54.1 percent had ever visited dental clinics over the last year, and 53.4 percent hadn't received any preventive treatment during the same period of time. 2. As to their self-perception of oral health status, 80.1 percent didn't find themselves to be in good oral health. 3. Regarding the influence of their general characteristics, their self-efficacy was statistically significantly different according to their gender (p = .022). Their control of oral health varied statistically significantly with their major(p = .000), and whether or not they smoked (p = .004) made a statistically significant difference to that as well. Their oral health knowledge differed statistically significantly with their gender (p = .000), major(p = .000) and age group(p = .000), and whether or not they smoked(p = .006) made a statistically significant difference to that as well. 4. As for correlation among the variables, better oral health promotion behaviors were found among those whose self-efficacy was higher, whose control of oral health was better and who had more knowledge on oral health. 5. Preventive treatment, control of oral health and self-efficacy were identified as the variable that affected their oral health promotion behaviors.

Composition of oral microbial flora is suggested to play a role in the maintenance of oral health. Among them, Streptococcus mutans plays an essential role in the formation of dental plaque and it is being noticed as incipient infective bacteria of dental caries. The purpose of this study was to prepare the basic data about distribution of Streptococcus mutans detected from saliva by measuring colony density. It is well known that smoking as well as drinking is a factor of dental caries, however there are few investigations about distribution of Streptococcus mutans either smoking or drinking. The materials of this study were collected from students of dentistry college with general characteristics obtained by self-administered questionnaires. Students were asked to gently chew the paraffin to get saliva for 1 minute. Bacitracin disc in the culture medium was activated for 15 minutes, and then sample was incubated in the activated medium at $37^{\circ}C$ incubator for 48 hours. Streptococcus mutans colonization per 1 ml saliva was measured by the number of criteria. The severe levels of dental caries activity were significantly increased in the case of smoking (from 5.6% to 10%) or drinking (form 0% to 7%), respectively. Also, dental caries activity increased according to smoking and drinking periods longer. However, using the SPSS analytical process (Mann-Whitney's U), no significant differences were observed between the smoking and the non-smoking or the drinking and non-drinking, respectively. These results obtained from dental caries activity of saliva suggest that distribution of Streptococcus mutans following smoking or drinking can be used as a significant information for oral health.

Purpose: The purpose of this study was to examine the relationship of the general characteristics of health-related majors to their life expectancy scale, depression scale, health perception scale, subjective wellbeing scale, somatic symptom scale and college life stress scale. And it's also meant to analyze influential factors for their stress about college life. Methods: The subjects in this study were the students who were in the department of dental laboratory technology and the department of dental hygiene at a college located in the region of Iksan, North Jeolla Province. Data were gathered in November and December, 2012. The life expectancy scale, depression scale, health perception scale, subjective wellbeing scale, physical symptom scale, somatic symptom scale and college life stress scale of the general characteristics were analyzed by t-test and one way analyses of variance (ANOVA) and the Duncan's multiple range test at the 95% confidence level to assess the statistical significance. And stepwise multiple regression analysis was conducted to determine what factors would affect the stress of the students about college life. The data were analyzed with the windows ver. 12.0(SPSS GmbH, Germany) statistical software program. Results: Among the general characteristics, there were significant differences according to gender and age in all the variables that were life expectancy scale, depression scale, health perception scale, subjective wellbeing scale, physical symptom scale and college life stress scale. 61.3% of the students responded they slept for six hours or less, and the respondents who slept for six hours or less scored significantly statistically lower in health perception scale, subjective wellbeing scale and physical symptom scale. As for college life stress, the respondents who got depressed more often, whose subjective peace or happiness was lower, whose life expectancy was lower, who had worse physical symptoms, whose living standard was lower and whose academic year was lower were under heavier stress about their college lives. Conclusion: As the worse physical health and worse mental health(life expectancy, depression, health perception, subjective wellbeing and physical symptoms, etc.) of the college students led to heavier stress about college life, how to promote their physical health and mental health should discreetly be considered, and every necessary measure should be taken to improve their physical and mental health.

The aim of this study was to analyze the relationship between salivary flow, salivary buffer capacity, level of mutans streptococci and dental caries experience in Korean dental college students. A total of 81 students of the school of dentistry, Chonbuk national university, mean age of 26.1 years, were subjected to oral examination to establish the DMFT and DMFS according to WHO guidelines. Saliva samples from the students were collected for quantitating stimulated and unstimulated salivary flow rate. Buffering capacity was estimated using a commercial colorimetric strip test, and number of mutans streptococci was determined from stimulated saliva using a strip mutans test. The means of DMFT and DMFS were 6.57 and 12.65, respectively. The stimulated salivary flow rate was correlated with DMFT(${\acute{o}}\;=\;-0.219$) and high levels of salivary mutans streptococci were significantly correlated with higher DMFT and DMFS scores(P<0.05). Level of mutans streptococci was significantly correlated with dental caries experience, in both DMFT and DMFS score, and buffering capacity was inversely correlated to DMFT score. However, unstimulated salivary flow rate was not correlated with caries experience.
