Objectives: It is crucial to detect and prevent oral problems early. Older adults, in particular, should go for regular dental checkups to maintain a healthy oral environment. This study identified the factors affecting regular dental examinations and unmet dental needs in older adults. Methods: This study analyzed 3,362 older adults aged 65 or over using the data from the 7th Korean National Health and Nutrition Examination Survey (KNHANES). Frequency analysis was performed on general characteristics. In addition, chi-square tests were done to determine differences in regular dental checkups and unmet dental needs according to general characteristics. Logistic regression analysis was performed on factors influencing regular dental checkups and unmet dental needs. Results: Factors influencing regular dental checkups were statistically significant according to residential areas, level of education, household income, and levels of physical activity (p<0.05). Factors influencing unmet dental needs were statistically significant according to residential areas, level of education, private medical insurance, and levels of dental pain (p<0.05). Conclusions: National level policy strategies should be implemented to improve the oral health of older adults. These strategies should encourage regular dental checkups to effectively lower the rate of unmet dental needs.

Current treatment concept of dental caries has been changed, because it has been proved that it is a preventable disease. The philosophy has been changed from purely restorative treatment to preventive caries control. Therefore the methods or criteria of oral examination has been changed. The clinician have to detect not only cavitation, but also the lesion of non-cavitation stage. International Caries Detection and Assessment System II (ICDAS II) was developed recently, which is a new criteria of classification of dental caries. This system was based on the current concept of prevention, early detection and patient-centered management of caries. Therefore this philosophy is in accord with the perspective of pediatric dentistry. The purpose of this article is to introduce this system for oral examination of children.

Background: With increased interest in oral health, several efforts have been made to improve oral health conditions. To achieve this, needs for oral health must be precisely determined and accurately measured. Therefore, factors influencing both objective unmet dental needs, which were determined by experts, and perceived unmet dental needs, which were determined by patients, were examined in this study. Methods: Responses of 17,735 respondents aged greater than 19 years from the Korean National Health and Nutrition Survey collected using the fifth (2010~2012) rotation sample survey were analyzed. Based on the information collected from the survey and dental examination, we determined the associations between the independent (sex and socioeconomic level) and dependent variables using a chi-squared test. Moreover, ordinal logistic regression analyses on multiple categorical values were performed using perceived and objective dental needs as the dependent variables. Results: Generally, factors influencing both perceived and objective dental needs were similar. These included sex, household income, educational level, private insurance, and subjective oral health status. However, the high-income groups had lesser perceived and objective dental needs compared to the low-income groups. Furthermore, factors such as sex, educational level, and marital status had different influence on both needs. Conclusion: Generally, factors that affect perceived and objective dental needs were similar. To minimize unmet dental needs, factors influencing both perceived and objective dental needs should be examined for a broad dental insurance coverage, and efforts to prevent oral diseases are also required.

Purpose: This descriptive study was conducted to examine the status of the health examination in child care centers. Method: The participants in this study were 631 child care centers. A self report questionnaire on health examination which has been examined for content validity, was distributed by mail to 2,000 child care centers using randomized sampling. Result: Of the sample, $76.2\%$ child care centers had done health examination for children. Height & weight, urinalysis, dental check, anemia test and visual acuity were the most frequently performed items. The rate for maintaining a health record was highest in the national/public child care centers. Child care centers more closely related to community health centers, showed higher rates of health examination. Conclusion: Health care personnel and financial aids should be provided for child care centers to enhance the level of health management of children.

Objectives: The objective of the study was to review the correlation between self-perceived oral health status and periodontal diseases in elderly Koreans, using data from the $6^{th}$ (2nd year) Korea National Health and Nutrition Examination Survey (2014). Methods: The subjects for this study were a total of 1,454 elderly people aged 65 years or older who responded to the health questionnaires of the $6^{th}$ (2nd year) Korea National Health and Nutrition Examination Survey conducted in 2014. Their general characteristics were analyzed using frequency analysis, while a cross-tabulation analysis (${\chi}^2-test$) was performed to understand the correlation with periodontal diseases. To clarify any effect of self-perceived oral health status on periodontal diseases, the selected variables were controlled and subsequently analyzed according to the logistic regression analysis. Results: In terms of the difference between elderly people with periodontal disease and those without periodontal disease, higher prevalence rates of periodontal diseases were found in women, those of younger age, those with lower educational and income levels, those with poorer subjective oral health status, those in the presence of chewing discomfort, those who had a toothbrushing frequency of twice per day, and/or those who had received no oral examination over the previous one year. Regarding the effect of self-perceived oral health status on periodontal diseases, 1.78-fold and 1.74-fold higher prevalence rates of periodontal diseases were shown with poorer subjective oral health status and in the presence of chewing discomfort, respectively. Conclusions: Based upon the results above, it is considered that a better understanding of self-perceived oral health status is necessary for a healthy life of the elderly. Furthermore, constant relevant studies and effective prevention programs intended to moderate the progress of or prevent periodontal diseases in the elderly in communities should be performed and implemented for the sake of better quality of life and oral health.

Objectives: Dental caries and periodontitis are major oral bacterial infections associated with dental plaque. Infection and inflammation play a role in carcinogenesis, and a significant link has been found between some highly prevalent oral and dental diseases and some types of cancer. Therefore, the aim of this study was to evaluate the relationship between cancer and oral health among Korean adults. Methods: Data from the 6th Korea National Health and Nutrition Examination Survey were used to analyze the incidence of cancer according to oral health. Demographic and socioeconomic statuses and oral behavior of the participants was analyzed using complex chi-square tests. Logistic regression was used to analyze the relationship between a high DMFT index and cancer by calculating the 95% confidence intervals. Results: In total, 6,450 case-control subjects were included. Significant difference was observed in the DMFT index, but not in periodontal diseases, between the cases and controls. The odds ratio for cancer was 1.80 (95% confidence interval: 1.18 to 2.73) in the high-risk group. However, no significant difference was observed after adjusting for age, education level, and income. Conclusions: The results provide potential evidence of a significant association between cancer and oral disease.

This study examined the relationship between the current chewing difficulty and the dental prosthesis needs of the elderly Koreans to improve their oral health status. A total of 1,177 subjects over 65 years who participated in the the Five Korea National Health and Nutrition Examination Survey were examined. An oral examination was conducted to determine the number of missing teeth and dental prosthesis required. A questionnaire was given to measure the sociodemographic characteristics, concerns about oral health, chewing ability and pronunciation ability. Statistical analysis was done using the SPSS 19.0 program. The percentage of the current chewing difficulty in Korean elderly was 42.9%. After adjusting for confounder variables, the odds ratio of the fixed prosthodontics needs were 1.22 (95% CI; 0.74 to 2.02), the odds ratio of partial denture needs were 2.47 (95% CI; 1.71 to 3.56) and the odds ratio of the full denture needs were 2.06 (95% CI; 0.73 to 5.81). The dental prosthesis needs were associated with the current chewing difficulty. Therefore, dental prosthesis support policy and public oral health promotion for the elderly is necessary.

Objectives: This study was to examine the association of sugar-containing snacking habits with dental caries and periodontal diseases. Methods: This study was conducted on 2,807 adults who answered both oral examination and food intake frequency survey in the data of 2015 Korea National Health and Nutrition Examination Survey. The intake frequency of sugary snacks was selected from 17 kind of snacks, which had high sugar content and could affect oral disease. We used the complex sample logistic regression using SPSS 23.0 confirmed the correlation of sugary snack intake frequency and oral diseases. Results: 16.9% of all adults had a sugary snack at least three times a day. 20.7% of dental caries patients and 25.8% of people with periodontal diseases consumed sugary snacks more than three times a day. Especially, periodontal diseases were 1.51 times higher(p=0.008) in three or more consuming snacks group than that who ingested sugary snacks less than six times a week, by correcting the general characteristics and oral health behaviors. Conclusions: Oral health in adults affects oral health in old age, so from a public health perspective, integrated intervention is required to manage the self-cultivation health and to create correct eating habits.

Objective: To evaluate transverse skeletal and dental changes, including those in the buccolingual dental axis, between patients with skeletal Class III malocclusion and facial asymmetry after bilateral intraoral vertical ramus osteotomy with and without presurgical orthodontic treatment. Methods: This retrospective study included 29 patients with skeletal Class III malocclusion and facial asymmetry including menton deviation > 4 mm from the midsagittal plane. To evaluate changes in transverse skeletal and dental variables (i.e., buccolingual inclination of the upper and lower canines and first molars), the data for 16 patients who underwent conventional orthognathic surgery (CS) were compared with those for 13 patients who underwent preorthodontic orthognathic surgery (POGS), using three-dimensional computed tomography at initial examination, 1 month before surgery, and at 7 days and 1 year after surgery. Results: The 1-year postsurgical examination revealed no significant changes in the postoperative transverse dental axis in the CS group. In the POGS group, the upper first molar inclined lingually on both sides (deviated side, $-1.8^{\circ}{\pm}2.8^{\circ}$, p = 0.044; nondeviated side, $-3.7^{\circ}{\pm}3.3^{\circ}$, p = 0.001) and the lower canine inclined lingually on the nondeviated side ($4.0^{\circ}{\pm}5.4^{\circ}$, p = 0.022) during postsurgical orthodontic treatment. There were no significant differences in the skeletal and dental variables between the two groups at 1 year after surgery. Conclusions: POGS may be a clinically acceptable alternative to CS as a treatment to achieve stable transverse axes of the dentition in both arches in patients with skeletal Class III malocclusion and facial asymmetry.
