To investigate knowledge and attitude of parents about early childhood caries and dental caries prevention, a questionnaire survey was conducted on 247 parents of children who had oral screening experience among 3 to 5 years old children in 3 kindergartens in Jeonju city. A total of 220 completed questionnaires were selected for final analysis. The overall perception of the parents about oral health of the children was 82.3 points (10.7 / 13) in terms of 100 points. There were statistically significant correlations between maternal age (p = 0.027), maternal education level (p = 0.002), household monthly income (p = 0.000) and maternal oral health knowledge level. The main source of oral health information was 'dentist and dental hygienist'(83.6%) followed by 'Web search'(22.3%). Compared with the previous studies, the level of knowledge of parents about oral health of the children was improved. However, in order to raise awareness of the parents about the poorly assessed items in this study, it is necessary to increase the participation rate by advertising the national dental screening program for infants and children and make efforts to improve the quality of oral health education in screening.

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.

Family type is not only an important sociodemographic variable for health studies but also influences the health behavior and health condition of individuals. This study assessed a representative sample to see whether family type is associated with health behavior in Korean adults age 65 and older. This is a cross-sectional study of 9,535 Korean elderly who participated in the 2010-2012 Korean National Health and Nutrition Examination Survey. The subjects were classified as couple cohabitation, couple-offspring cohabitation, alone, or alone-offspring cohabitation. We assessed the relationship between family type and six health behaviors (smoking, high risk drinking, walking, oral examinations, health screenings, and influenza vaccinations) after controlling covariates. The "alone" classification had a significantly higher risk of no health screening, but was more likely to have an influenza vaccination than couples. Significant interactions between family type and healthy behavior were observed with oral health screening, influenza vaccination, and smoking {Odds ratio (95% confidence interval), 1.452 (1.066-1.980), 1.375 (1.083-1.747), 2.246 (1.604-3.146)}. There is a significant association between family type and healthy behaviors.

Oral cavity cancer accounts for approximately 3-4% of all malignancies and is a significant worldwide health problem. The Korea Central Cancer Registry estimates that there will be approximately 1500 new cases of oral cancer in Korea. Oral cancer occurs most commonly in middle-aged and elderly individuals. The majority of oral malignancies occur as squamous cell carcinomas and despite remarkable advances in treatment modalities, the 5-year survival rate has not significantly improved over the past several decades, hovering at about 50% to 60%. The unfavorable 5-year survival rate may be attributable to several factors. First, oral cancer is often diagnosed at a late stage, with late stage 5-year survival rates as low as 22%. Additionally, the development of secondary primary tumors in patients with early stage disease has a major impact on survival. The early detection of oral cancer and premalignant lesions offers the promise to cure chance of oral cancer. The major diagnostics moddalities for oral cancer include oral cavity examination, supravital staining, oral cytology, and optical detection systems. But the clinical finding of oral mucosa is the most important key to confirm the oral cancer until now. The traditional clinical examination of oral cavity can be performed quickly, is without additional diagnostic expense to patients, and may be performed by health care professionals. Therefore, clinicians must be well-acquainted with clinical characteristics of oral cancer and practice routine screening for oral cancer in dental clinic to decrease the morbidity and mortality of disease.

Objectives: The purpose of this study was to identify the effects of general and oral health status on dementia. Methods: Questionnaires were used for the KDSQ-C (Korean Dementia Screening Questionnaires-Cognition) and to investigate the oral health status of the participants. An independent t-test was conducted to analyze the differences between general health and oral health status depending on the normal and suspected dementia groups. Logistic regression analysis was performed to assess the effects of general and oral health status on dementia. Results: Regarding the health status of the subjects assessed by the KDSQ-C, the higher the current health status and the higher the exercise status, the lower was the dementia level (p<0.05). During the assessment of oral health conditions in KDSQ-C subjects, dementia was more suspected in subjects with dental decay and periodontal disease than in those without dental decay (p<0.05). Conclusions: Dementia has been confirmed to be closely related to general and oral health conditions. Therefore, oral health-related programs are essential for dementia prevention programs. Since dental hygienists are best suited for providing oral care to older adults with dementia, it is considered essential to reflect their occupation in future national policies.

Purpose : To report the incidence of radiological findings from screening panoramic radiographs and verify the validity of the panoramic radiography for screening purposes. Materials and Methods : Six thousand one hundred and sixty panoramic radiographs taken from the patients visiting the Health Promotion Center of CNUH were selected for this retrospective study. Panoramic radiographs were examined into the following pathologic conditions : the presence of periodontal bone loss, dental caries, periapical radiolucencies, retained roots, impacted supernumerary teeth, impacted third molars, odontoma, cystic lesions other than radicular cyst, sialoliths, and mixed radiolucent-radiopaque lesions. Number of pathologic conditions and Prevalence values were recorded. Results: The prevalences of pathologic conditions were $72.9\%$ of periodontal bone loss, $32.2\%$ of dental caries, $11.9\%$ of periapical radiolucencies, $10.8\%$ of retained roots, $0.4\%$ of root fracture, $1.0\%$ of impacted supernumerary teeth, $1.0\%$ of impacted third molars, $0.06\%$ of odontoma, $0.08\%$ of cystic lesion other than radicular cyst, $0.2\%$ of prolonged retention of deciduous tooth, $0.1\%$ of sialolith, and $0.04\%$ of mixed radiopaque and radiolucent lesion. Conclusion : Although the panoramic radiograph should not be used to replace intraoral radiographic and clinical examinations, this study showed that many dental pathologic conditions could be detected on panoramic radiographs. The panoramic radiograph might serve as a diagnostic aid in dental health evaluation programs.

Aptamers are composed of single-stranded oilgonucleotides that can selectively bind desired molecules. It has been reported that RNA or DNA could act as not only a genetic messenger but also a catalyst in metabolic pathways. RNA aptamers (average sizes 40-50 bp) are smaller than antibodies and have strong binding capacities to target molecules, similar to antigenantibody interactions. Once an aptamer was selected, it can be readily produced in large quantities at low cost. The objectives of this study are to screen and develop aptamers specific to oral pathogens such as Porphyromonas gingivalis, Treponema denticola, and Streptococcus mutans. The bacterial cell pellet was fixed with formaldehyde as a target molecule for the screening of aptamers. The SELEX method was used for the screening of aptamers and a modified western blot analysis was used to verify their specificities. Through SELEX, 40 kinds of aptamers were selected and the specificity of the aptamers to the bacterial cells was confirmed by modified western blot analysis. Through the SELEX method, 40 aptamers that specifically bind to oral pathogens were screened and isolated. The aptamers showed possibility as effective candidates for the detection agents of oral infections.

Objectives: The Korea National Health and Nutrition Examination Survey (KNHANES) is a national surveillance system that has been assessing the health and nutritional status of Koreans since 1998. Based on the National Health Promotion Act, the surveys have been conducted by the Korea Centers for Disease Control and Prevention (KCDC). Methods: An oral examination as part of The National Health and Nutrition Examination was proposed to calculate the sample design and survey participation. The surveying system was presented by classifying the measurement environment, screening, and survey items by year, and the merits and limitations of using the data were suggested by examining the status of survey quality management and the process of disclosing raw data. Results: This nationally representative cross-sectional survey samples approximately 10,000 individuals each year and collects information on oral examinations and oral health interviews. Data for the oral health component of KNHANES was obtained to assess the oral health status of Koreans and determine the prevalence of dental caries and periodontitis. The oral health data quality control of KNHANES was composed of three parts: "Education Program" and "Field Training Program" for quality control of oral health examiners (dentists) by the professional academy, and "Data management" by the KCDC. After completion of the three-step data check, the indicators of dental caries, periodontal disease, and oral health behavior were published in the National Health Statistics. Conclusions: To achieve the goals of oral health indicators, we will continue to monitor so that we can use it as basic data for oral policies and carry out various linkage analyses related to oral diseases.

Purpose: We investigated correlations between the findings of oral examinations and panoramic radiography in order to determine the efficacy of using panoramic radiographs in screening examinations. Methods: This study included patients who visited dental clinics at National Health Insurance Service (NHIS) Ilsan Hospital for checkups during 2009-2015 and underwent panoramic radiographic examinations within 1 year prior to the oral examinations. Among the 48,006 patients who received checkups, 1,091 were included in this study. The data were evaluated using the Cohen kappa and interrater agreement coefficients. Accuracy, sensitivity, and specificity were calculated using data from the panoramic radiographs as true positive diagnoses. Results: The interrater agreement coefficient for occlusal caries was 28.8%, and the Cohen kappa coefficient was 0.043 between the oral and panoramic radiographic examinations. Root caries and subgingival calculus were only found on the radiographs, while gingival inflammation was found only by the oral examinations. The oral examinations had a specificity for detecting occlusal dental caries of 100%, while their sensitivity for proximal dental caries and supragingival calculus was extremely low (14.0% and 18.3%, respectively) compared to the panoramic radiographic examinations. The oral examinations showed a relatively low sensitivity of 66.2% and a specificity of 43.7% in detecting tooth loss compared with panoramic radiography. Conclusions: Panoramic radiography can provide information that is difficult to obtain in oral examinations, such as root caries, furcation involvement, and subgingival calculus, which are factors that can directly affect the survival rate of teeth. It therefore seems reasonable and necessary to add panoramic radiography to large-scale health checkup programs such as that provided by the NHIS.

The present study aimed to examine the influence of mental health factors on oral health factors using data from the Korean National Health and Nutrition Examination Survey (KNHANES). A total of 1,548 elderly individuals aged over 65 years who completed the screening and health questionnaire were selected as the final study participants. The psychological health factors related to perceived oral health status were depression and stress when the gender was controlled, and in terms of gender, both elderly male and female individuals were stressed and depressed. These results suggested that the psychological health of elderly individuals negatively affects not only perceived oral health but also the quality of life. In addition, the psychological health of the elderly individuals should be systematically managed along with oral health care and overall health care and lifestyle. If a comprehensive health management system is available for low-income groups or an elderly person living alone, it should positively affect and improve the quality of life of elderly individuals.
