The purpose of this study was to look into the perception, experience, treatment of early childhood caries (ECC) and influential factors of perception in order to provide basic data useful for preventing the ECC by examining the relationship between oral health of young children in infancy and mother. In this study, 277 mothers were surveyed who had children in children under 6 years old and visiting the pediatrics, day care center, and pediatric dental clinics located in Daegu and Gyeongsangbuk-do from July 10, 2013 to September 5 of the same year. The results obtained from the survey were analyzed through chi-square test, t-test, and binary logistic regression analysis by using the SPSS 18.0, a statistical program. The results of analysis showed that ECC in children under 6 years old was associated with mother's age, education background of mothers, number of children and monthly income and had a significant correlation with mother's oral health-related knowledge and oral health care of their children. Thus, it would be necessary to develop oral health education programs and implement such oral health education programs at a national level on a regular basis for the mothers of young children in infancy and would-be mothers in order to reduce the ECC in infancy and promote oral health.

Objectives: This study examined the characteristics and related factors by comparing the lifestyles and health behaviors between Korean Seventh-day Adventists and the general population of Korea. Methods: A survey was conducted of 878 people more than 20-years-old Korean Seventh-day Adventists who live in the metropolitan area and 3,000 people more than 20-years-old who live in the metropolitan area in 4th (2nd year) National Health and Nutrition Survey. A comparison of health behaviors related to health screenings, smoking, drinking, physical activity, subjective stress, weight management, and oral health was analyzed using a chi-square test. Logistic regression analysis was used to identify the contributing factor to the health behavior. Results: Health screening rates among Korean Seventh-day Adventists were higher than the general population (p<0.001), but Korean Seventh-day Adventists showed lower rates of health screening in the 20-30 ages. Lifetime smoking experience rates and current smoking rates were significantly lower in the Korean Seventh-day Adventists than in the general population (p<0.001). The success rate of smoking cessation among ex-smokers of Korean Seventh-day Adventists were very high. In terms of the drinking rate, Korean Seventh-day Adventists were significantly lower than the general population (p<0.001). The drinking rate of men was higher than women (p<0.001). Moderate physical activity of men were higher than women in Korean Seventh-day Adventists (p<0.001). Conclusion: The lifestyles and health behaviors of Korean Seventh-day Adventists, such as tobacco smoking and alcoholic drinking, were eminently healthier than the general population.

In this study, professional oral care was provided and 3 times a day twice a week by a dental hygienist for 3 months from July 24 to October 25, 2011, to 43 long-term patients in a single nursing facility located at the city of D, and the number of mutans strepococci colonies within the saliva and the level of salivation were then analyzed after 3 samplings with an interval of 1 month to compare the intraoral conditions among the subjects and examine the effects of professional oral care on the Streptococcus mutans population in the intraoral region of long-term patients in a nursing facility. The level of salivation was elevated from 5.8 ml to 6.4 ml after one month and to 7.5mL after two months. The population of bacteria decreased from $6{\times}10^8CFU/ml$ to $3{\times}105CFU/ml$. In terms of the change in the bacterial population in accordance with systemic diseases, the patients with hypertension and diabetes showed a meaningful decrease in the population. As more dental charge and prosthesis are present, the number of bacteria decreased significantly. On account of the close relationship between a professional oral care and the population of Streptococcus mutans at the intraoral region of long-term patients in nursing facilities, various dental health programs should be researched and developed to consider the characteristics of long-term patients in nursing facilities and manage them continuously but effectively.

There is tremendous variability in the ways patients present with taste problems. Because of complex and multifactorial etiological background, it is not simple to evaluate patients with taste disorders. Accurate assessment of patients' status by prudent, thorough history taking and symptom analysis is the most essential for exact diagnosis of taste disorders. The aim of this study was to investigate the clinical characteristics of patients with taste problems as a primary complaint. Consecutive series of 50 patients (12 males and 38 females, mean age $53.6\;{\pm}\;14.7$ years) were included for the present study. All subjects were requested to complete a comprehensive questionnaire. Clinical evaluation procedures included oral examination, interview, questionnaire analysis, panoramic radiography, blood test and measurement of salivary flow rate. The obtained results were as follows: 1. Among the patients, 36 patients (72%) complained of oral mucosal pain or burning sensation. Of these patients, 18 patients (36%) were diagnosed as burning mouth syndrome. 2. Nineteen patients (38%) complained of subjective oral dryness. The flow rate of unstimulated whole saliva was less than 0.1 mL/min in 14 patients (28%) and 17 (34%) had a stimulated whole salivary flow rate of less than 0.5 mL/min. 3. Among the types of taste disorders, hypogeusia, the most frequently reported, was found in 25 patients (50%), dysgeusia in 18 patients (36%), phantogeusia in 15 patients (30%), hypergeusia in 10 patients (20%), and ageusia in 5 patients (10%). Nineteen patients (38%) reported more than one type of taste disorder and the most frequent combination was dysgeusia + hypogeusia (n=6, 12%). 4. Based on data from the medical and dental histories and examinations, the patients were assigned to 12 probable causal categories. Taste disorders due to oral mucosal diseases and idiopathic taste disorder were the most frequent (n=9; 18%, each), followed by psychogenic taste disorder (n=8; 16%), drug-induced taste disorder (n=7; 14%), and taste disorder due to dry mouth (n=6; 12%). These 5 categories of taste disorder accounted for 78% of all cases in this study.

The prevalence of periodontal disease was steadily increased. The best prevention methods for periodontal disease are teeth brushing and scaling. The purpose of this study was to investigate the status of scaling experience and related factors among some workers. Total 455 workers in 5 manufacturing companies in Gwangju were selected using convenience sampling method. General characteristics, work-related characteristics, oral health-related characteristics and scaling experience were collected by self-reported questionnaires. Chi-square tests, t-tests and multiple logistic regression analysis were performed to investigate the factors influencing the scaling experience using SPSS software. Statistical significance was defined as a p-value<0.05. The proportion of scaling experience during the past year was 47.0%. In simple analysis, age, current working position, number of oral disease, interest in oral health, use of secondary oral products, oral health screening use, oral health education experience and awareness of scaling inclusion in the National Health Insurance (NHI) coverage were associated with scaling experience. Finally, the odds ratios (ORs) for scaling experience were significantly higher in younger subjects (adjusted OR [aOR], 3.09; 95% confidence internal [CI], 1.60~5.96), assistant manager (aOR, 2.68; 95% CI, 1.55~4.63), subjects with high interest in oral health (aOR, 2.15; 95% CI, 1.02~4.52), subjects with oral health screening use (aOR, 2.76; 95% CI, 1.50~5.11) and awareness of scaling inclusion in the NHI coverage (aOR; 2.91, 95% CI, 1.80~4.72) in multiple logistic regression analysis. Scaling experience was relatively low (47.0%). The related factors with scaling experience were age, working position, use of screening and awareness of scaling inclusion in the NHI coverage. Considering these factors will increase the utilization rate of scaling.

This study was executed to find the effects of dietary control and oral health care on dental caries and oral problems in elementary school students, including the effects of nutritional and oral health education on the prevention of dental caries. 1. The oral health study found that 88.9％ of students brushed their teeth everyday, 63.7％ 2 times a day, and 50.4％ in the morning and at night. 2. According to the general characteristics whether or not, the female students had more dental caries than the males, and 29.1％ of the students that had dental caries ate snacke 1 or 2 times a day. 3. After the nutritional education, more students brushed their teeth in the after meal 4. According to gender, grade and nutritional education for oral health care, male students and higher grade students were more aware that “brushing teeth after meals is better than before”. The male and higher grade students, after the nutritional education, were more aware that “Bones and teeth are made from calcium”, and “Fluorine prevents teeth from dental caries” and the differences between the genders were statistically significant in relation to both these facts (p〈0.05) and before and after education (p〈0.01). The male and higher grade students, and those nutritionally educated were more conscious that “vegetables and fruits are good for teeth”, with the differences before and after the nutritional education were statistically significant (p〈0.05). The male and higher grade students were well aware that “Foods that have sugar cause dental caries”, and significant differences were shown between grades (p〈0.05). The male and higher grade students, after the nutritional education and were well aware that “Milk is good for teeth”, with a significant gender difference (p〈0.05). The female and higher grade students, and those after nutritional education were well aware that “Dental caries can not be perfectly cured once it had already occurred”. after nutrition, but not much differences.
