Objective: The aim of this retrospective study was to assess the midfacial soft tissue changes following maxillary expansion using micro-implant-supported maxillary skeletal expanders (MSEs) in young adults by cone-beam computerized tomography (CBCT) and to evaluate the correlations between hard and soft tissue changes after MSE usage. Methods: Twenty patients (mean age, 22.4 years; range, 17.6-27.1) with maxillary transverse deficiency treated with MSEs were selected. Mean expansion amount was 6.5 mm. CBCT images taken before and after expansion were superimposed to measure the changes in soft and hard tissue landmarks. Statistical analyses were performed using paired t-test and Pearson's correlation analysis on the basis of the normality of data. Results: Average lateral movement of the cheek points was 1.35 mm (right) and 1.08 mm (left), and that of the alar curvature points was 1.03 mm (right) and 1.02 mm (left). Average forward displacement of the cheek points was 0.59 mm (right) and 0.44 mm (left), and that of the alar curvature points was 0.61 mm (right) and 0.77 mm (left) (p < 0.05). Anterior nasal spine (ANS), posterior nasal spine (PNS), and alveolar bone width showed significant increments (p < 0.05). Changes in the cheek and alar curvature points on both sides significantly correlated with hard tissue changes (p < 0.05). Conclusions: Maxillary expansion using MSEs resulted in significant lateral and forward movements of the soft tissues of cheek and alar curvature points on both sides in young adults and correlated with the maxillary suture opening at the ANS and PNS.

Objectives: The purpose of this study was to compare oral symptoms in middle school and high school students of multicultural and ordinary families in Korea. Methods: We used data from the web-based survey of the National 2014 Korean Youth Risk Behavior of Korean Center for Disease Control. A total of 71,174 subjects responded about their father or mother's Korean nationality. We classified a subject as an adolescent of a multicultural family if aparticipant's father or mother's nationality was not Korean. Data was analyzed using SPSS Ver. 19.0. Results: High school students of multicultural families have experienced more oral disease symptoms, compared to high school students of ordinary families. After adjusting general characteristics and oral health behaviors, high school students of multicultural families experienced 1.78 times higher frequency of oral disease symptoms compared to high school students of ordinary families. Conclusions: The family type and age characteristics of adolescents should be considered when establishing policies and institutions targeting adolescents to improve oral health.

Objectives: To investigate the association of problematic Internet use with oral health behaviors and oral health status in a nationally representative sample of Korean adolescents. Methods: Data from the 2010 Korea Youth Risk Behavior Web-based Survey (73238 Korean adolescents; mean age $15.06{\pm}1.75years$; age range, 12-18 years) were used. Problematic Internet use was measured using the Korean Internet Addiction Proneness Scale for Youth-Short Form. Self-report questionnaires were used to assess oral health behaviors and oral health status of adolescents. Results: Problematic Internet users were less likely to brush their teeth frequently [adjusted odds ratio (AOR)=0.59; 95% confidence interval (CI)=0.56-0.63] and at school after lunch (AOR=0.89; 95% CI=0.83-0.94) as well as more likely to perceive their oral health to be poorer (AOR=1.63, 95% CI=1.54-1.72) and experience oral symptoms (AOR=1.75, 95% CI=1.65-1.86) compared to usual Internet users. Conclusion: The study results indicate that problematic Internet use may adversely affect the oral health of Korean adolescents. Thus, oral health screening and Internet-based education are needed for adolescents experiencing problematic Internet use.

Objectives: The purpose of this study was to investigate the relationship between demographic characteristics, health factors, oral health factors and subjective body shape perception of adolescents in order to provide basic data for adolescents health management. Methods: This study was analyzed using Korea Youth Risk Behavior Web-Based Survey in 2015, where 68,043 adolescents in total participated. Data were analyzed by SPSS Ver. 21.0. Multiple regression analysis was used to analyze the relationships among health factors and oral health factors related to subjective body shape perception. Results: The analysis of the factors influencing the body shape perception of male adolescents showed that they tend to be low in school performance, low in family economic level, and high school students. The worse they perceive their subjective health to be, the more they feel stress, and the less frequently they brush their teeth per day. They had bad breath. The analysis of the factors influencing the body shape perception of female adolescents showed that they tend to be low in school performance, low in family economic level, and high school students. The worse they feel their subjective health is, the more they feel unhappy, and stressful, and the less frequently they brush their teeth per day. They feel pain during chewing, and have bad breath. Conclusions: In conclusion, it is necessary to consider educational intervention in adolescent life that will make them have proper perception of their body shape for proper health management of it. To make the intervention effective, we need to consider various factors such as health factors and oral health factors.

Stroke is the second cause of death worldwide, although the survival period is increasing after the occurrence of stroke, severe physical disability is caused with aftereffect. Oral inflammation is not limited to the oral cavity, it can cause malignant changes in other tissues and organs. In previous studies, we confirmed the relationship between tooth loss and stroke due to periodontal inflammation. The purpose of this study was to investigate the relationship between oral health and stroke such as oral hygiene behavior, tooth loss and periodontal disease among Korean adults over 40 years of age. This study was analyzed using the 6th Korea National Health and Nutrition Examination Survey (KNHANES) data. A total of 3,389 adults over 40 years of age were analyzed as final subjects. Socioeconomic statuses and oral health status was analyzed using a complex sample analysis technique. Logistic regression was used to analyze the relationship of oral health and stroke, and 95% confidence intervals were computed using SPSS. When the prevalence of stroke according to oral hygiene behavior was checked, the prevalence of strokes was lower in subjects who had a lot of brushings per day and subjects who used oral hygiene products (p<0.05). The risk of stroke was 2.17 times (95% confidence interval, 1.43~3.28) higher in the group with less than 19 remaining teeth, but it was not statistically significant as a result of adjusting for age and sex, income level, education level, drinking and smoking (p>0.05). Loss of teeth was found to be associated with the risk factor of stroke. Therefore, loss of teeth due to periodontal disease is an additional issue that should be considered as a risk factor for stroke.

The purpose of this study was to examine the levels of the subjective oral health awareness of local residents in the city of Changwon and Haman county in an effort to lay the foundation for the development of customized local oral health education programs. The 2015 community health survey data were used, and the data from 864 residents in Changwon and from 719 dwellers in Haman county were analyzed. The Changwon residents brushed their teeth after lunch more, received more oral checkups over the past year and had more scaling experience. The Haman residents had more experience of not receiving dental treatment. The subjective health awareness, subjective oral health awareness, chewing difficulty and periodontal health of the Haman dwellers were all worse, and all the levels of awareness were lower among the respondents who were older and who were diagnosed with hypertension and/or diabetes. The respondents who made use of dentures and who didn't brush their teeth after lunch had experience of not receiving dental treatment, and all the levels of health-related awareness were lower among the respondents who didn't receive dental checkups nor had scaling experience. To remedy the situation, efforts should be made to prevent and manage chronic diseases, and the establishment of a system that guarantees regular dental checkups and scaling is required. And the kind of environments that everybody can receive dental treatment when they want should be prepared. In order to change negative awareness, necessary measures should be taken to provide oral health education that is not temporary but sustainable and tailored to local characteristics and different life stages.

Objectives: This study aimed to confirm the relationship between toothbrushing practice after lunch and typical oral health behaviors in children and adolescents according to the subject and type of social support. Methods: The study used data from the 2010 Korean Survey on the Health of Youth and Children and selected 8,704 elementary, middle, and high school students as final targets. Multiple logistic regression was conducted to confirm the link between social support and toothbrushing after lunch. Results: The results showed that in elementary and vocational high school students, statistical significance of all social support variables disappeared after controlling for both demographic and social factors and oral symptom experience. However, in the middle school students, the emotional support of the neighbors and the emotional support of the teachers showed statistically significant effect on brushing daily after lunch (p<0.05). In general high school students, there was a significant association between family emotional support and toothbrushing after lunch (p<0.01). Conclusions: The oral health promotion program for children and adolescents needs to be integrated and coordinated with the overall health promotion program. In particular, it is believed that the school-based program can strengthen the practice of health behaviors by inducing behavioral changes based on the formation of healthy relationships and trust of colleagues and teachers. Therefore, it is necessary to develop social network-based programs including social support such as emotional health and healthy relationships that can be applied among children for oral health promotion.
