This study analyzed the effects of the nutrient intake on oral health and chewing difficulty according to the age group. The subjects were 5,855 participants of the third Korea National Health and Nutrition Examination Survey(KNHANES VI), 2015, Korea Centers for Disease Control and prevention and aged 20 years and over. The data were analyzed using SPSS Ver 21.0, classified as the difficulty in chewing group (DC) and no difficulty in chewing group (NDC). As a result, the DC rates were 5 times higher in the 60+ year age group (39.5%) than in the 20-39 year age group (8.1%). The DC group were experience periodontal disease (33.4%), dental caries (30.1%), diabetes (41.8%), myocardial infarction (57.3%), arthritis (44.0%), asthma (48.0%), and depression (41.9%). In addition, 86% of the DC group were experiencing speech problems. The DC group had significantly lower intakes (1446.59g), than the NDC group (1666.62g), and the protein, carbohydrate, dietary fiber and other dietary intake were significantly lower. These findings suggest that the chewing difficulty is related to the nutrient intake, and psychological status in the elderly DC group. Therefore, the care of chewing difficulties is essential for the elderly to maintain a healthy lifestyle. Accordingly, oral care and myofunctional therapy are needed to maintain oral health.

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.

The purpose of this study was to investigate the relationship between oral health behaviors and periodontal diseases in adult obese people. Using the original data of the second phase of the 6th National Health and Nutrition Survey, the final 4381 adults were extracted. We analyzed frequency and technical statistics and chi - square test and multiple logistic regression analysis using SPSS statistical program to confirm the association between body mass index, number of brushing, drinking, smoking and oral health status and behavior. As a result, the prevalence of periodontal disease decreased as the number of toothbrushing increased, and the prevalence of periodontal disease increased as the body mass index increased. Through this study, obesity, a global health issue, should be more concerned with oral care and develop oral health management programs.

With change in the pattern of disease occurrence and increase in the interest in health, efforts to assess the health status on patients covering their subjective awareness at the same time as clinical and objective evaluation on health are continued. To measure health-related quality of life can be one of these efforts. This study was performed to evaluate the relevance of the quality of overall health-related-life and oral health condition. Also the second year (2014) materials in the 6th the National Health and Nutrition Survey were applied to this study. The factors affecting general health related quality of life measured by EuroQol-5 dimension (EQ-5D) have been confirmed by gender, age, education level, income level, private health insurance, perceived health status, toothache experience during the last 1 year, remaining tooth number. As oral health plays an important role in determining the overall health conditions, objective oral health state influences the whole body health. Hence, it can be regarded that oral health is ultimately related to the general health-related quality of life.

Objectives: The purpose of this study is to contribute to providing more effective basic data for adults 'oral health management in their future. Methods: The study investigated factors that influence oral health care and oral health behavior depending on the heterosexual status for about one month from Aug. of 2017 on 20 unmarried adults living in Seoul and Gyeonggi-do. Statistical analysis of the collected data was performed using the SPSS WIN 21.0 statistical program. Results: The factors affecting the oral health behavior were high (p<0.001) while oral hygiene products (p<0.05) and interdental toothbrush (p<0.05) were found to have a positive effect on oral health behavior. However, it was found that the times of brushing were less than three (p<0.05) and the time for brushing was two minutes (p<0.05), which negatively affects oral health behavior. The concern of oral health was high (p<0.001), whiledental hygiene products (p<0.05), interdental toothbrush (p<0.05) and mouth saliva (p<0.05) were found to have positive effects on oral health care. Conclusions:Based on the results above, it was found that the concern and the behavior of oral health increased depending on the heterosexual status. The reason for this is that the motivation for oral care is more likely to be induced to make oneself attractive by making a resignation. Therefore, in order to promote oral health care and oral health activities, it is necessary to precede the motivation.

Oromandibular dystonia (OMD) is a form of focal dystonia that affects the masticatory, facial and lingual muscles in any variety of combinations, which results in repetitive involuntary and possibly painful jaw opening, closing, deviation or a combination of these movements. This study aimed to investigate clinical features and treatment type of OMD patients. By retrospective chart review, the study was conducted to consecutive OMD patients who visited a department of Oral Medicine and Orofacial Pain Clinic in a university dental hospital during Aug 2007 to Apr 2010. 78 OMD patients were identified with female preponderance (M:F=1:3.6) and a mean age of 72 years. Their mean duration of OMD was about 10 months. The most common chief complaints at the first visit was jaw ache, followed by uncontrolled, repetitive movement of the jaw and/or oral tissues, pain in the oral region(p=0.000). The most common subtype of OMD was lateral jaw-deviation dystonia, followed by combination and jaw-closing dystonia(p=0.001). While no apparent cause was recognized in over 60% of the OMD patients, peripheral trauma including dental treatment such as prosthetic treatment and extraction was the most frequently reported as precipitating factor(p=0.000). Medication was the 1st line therapy for our patients and anxiolytics such as clonazepam was given to most of them. Based on the results of this study, OMD is the disease of the elderly, particularly of women and causes orofacial pain and compromises function of orofacial region. Some patients considered dental treatment a precipitating factor. Dentists, therefore, should have knowledge of symptoms and treatment of OMD.

This study was conducted to examine the relations of oral health relevance to disabilities according to the relationship types between them and their guardian. The guardians were surveyed using self-writing questionnaires regarding the cohesion and communication process, and the oral health of disabled was analyzed by evaluation table. Total 78 copies were analyzed. SPSS win. 24.0 statistical program was used and the significance level was verified at .05. There was significance in the communication process(p<.01) according to the type of relationship with the disabled and their guardians. In oral health of the disabled according to the type of relationship with their guardians, there was significance in DMFT index(p<.01), first molar soundness(p<.01) and Pocket depth(p<.01).Therefore, the mother had a positive effect for the disabled on most items such as cohesion, communication process, and oral health. However, it is expected that policy support and research to increase the interests in oral health care management are needed for personal assistants, who showed a low impact on the cohesion, and communication process with disabled persons, and spouses, who showed a low influence on oral health of persons with disabilities.

The aims of this study were to evaluate the effect of native acidity upon dental hard tissues by measuring pH in mouth-rinse, which is on the market, and to evaluate even influence of dental stain caused by mouse-rinse given using for a long time. The experimental group was used Garglin, Nextcare, Listerine, and Hexamedin. The control group was used sterile distilled water. As a result, pH was indicated to be low in Nextcare(4.70) and Listerine(4.16). In a change of color tone, $b^*$ value of indicating Yellow-blue showed the lower value than the early color tone in all groups. There was statistical significance in Nextcare and Listerine. ${\Delta}L^*$ value of indicating light -dark gets darker after using Nextcare, Listerine and Hexamedine. A change(VHN) in surface hardness of enamel showed reduction in surface hardness after 14 days in Nexcare and Listerine. As a result of confirming a change in enamel surface by using Scanning Electron Microscopy, the erosion aspect on the enamel surface could be confirmed in groups of Nexcare and Listerine. Ra value in surface roughness of enamel could be observed the enamel surface, which got rougher compared to other experimental groups.
