Temporomandibular joint osteoarthritis (TMJ OA) causes destruction of the temporomandibular joint (TMJ) and can lead to occlusal changes such as anterior open bite in some patients. Consequently, these patients may experience difficulty in chewing food items and exhibit abnormal functional habits such as bruxism, preventing healing of the TMJ condyles. Treatment protocols include the use of traction appliances to reduce stress on the condyles. Unstable occlusions can lead to weakness of the masticatory muscles which, in turn, worsen the occlusal changes and complicate pain management. Therefore, the current study evaluated the condition of the masseter muscle using ultrasonography and educated patients on the execution of gum-chewing exercises for muscle strengthening. It also aimed to assess the effects of traction appliances and strengthening exercises on the masticatory muscles of patients with occlusal changes caused by TMJ OA.

In order to identify valuable factors for improving dietary quality of Korean rural elderly, the consumption frequency of food groups, dietary habits and health behaviors related to nutrient intakes of the elderly over 85 of Sunchang County were studied. The 171 subjects (61 males and 110 females) were chosen from Sunchang Province by stratified sampling. Among food groups, the consumption frequency of meat and fish groups influenced significantly on their nutrient intakes than the other groups. The subjects consuming more than 4 times per week of meat or fish had significantly higher nutrient intakes level than the other groups. The group consuming milk and milk products everday was higher in vitamin $B_2$ intake level than the other groups. Among dietary habits, the groups with good appetite and regular mealtime compared with the groups with low appetite and irregular mealtime had significantly higher nutrient intake levels. The family type was the determining factor of nutrient intakes. The subjects living with family members consumed higher nutrient intakes than the subjects living alone. The smoking and the alcohol consumption themselves did not affect nutrient intakes, but the subjects having alcohol consumption frequently more than once a day had lower nutrient intakes than the others. The group with dentures did not differ significantly from the without denture group in nutrient intakes; however, those who had chewing problems showed the lower nutrient intakes compared to those who did not have chewing problems. The subjects with more than two kinds of clinical symptoms had lower nutrient intakes than the subjects with less than two kinds of clinical symptoms. These results indicate that the identifying factors for desirable nutrient intakes of rural elderly were characterized as appropriate consumption frequencies of meat and fish, good appetite, living with family, regular mealtime, chewing without difficulty, and low incidence of chronic disease.

Objectives: The aim of this study was to evaluate the oral health status and behavior in Korean diabetic adults. Methods: The study subjects were 11,840 adults who participated in the fifth Korea National Health and Nutrition Examination Survey(2010-2012). Diabetic status was defined by doctors and fasting blood sugar(FBS) level. Oral health status was assessed by decayed-missing-filled teeth(DMFT), community periodontal index(CPI), periodontal disease, denture needs, limitation of oral function, and chewing difficulty. The oral health behavior was evaluated by oral examination within a year, brushing times a day, and use of auxiliary oral product. The data were analyzed by descriptive analysis, chi-square tests and multiple logistic regression analyses. Results: The prevalence rate of diabetes mellitus diagnosed by doctor and FBS was 8.3% and 10.2%, respectively. The prevalence rate of periodontitis was 25.4%. The proportions of $DMFT{\geq}20$, $CPI{\geq}3$, periodontal disease, denture needs, oral function limitation and chewing difficulty in the confirmed diabetic group by doctor were significantly higher than those of the non-diabetic group(p<0.05). In multiple logistic regression analysis, the adjusted odds ratio(aOR) for periodontal disease(aOR=1.73, 95% CI=1.41-2.12), presence of denture needs(aOR=1.40, 95% CI=1.06-1.84), limited oral function(aOR=1.43, 95% CI=1.15-1.78) and chewing difficulty(aOR=1.41 95% CI=1.13-1.77) in diabetic subjects were significantly higher than those of the non-diabetic subjects. There were similar associations between diabetes defined with FBS and oral health. In oral health behavior, diabetic subjects had significantly lower odds ratios for oral examination(aOR=0.76, 95% CI=0.60-0.98), brushing time ${\geq}2$ times(aOR=0.73, 95% CI=0.57-0.93), and auxiliary oral products(aOR=0.74, 95% CI=0.59-0.94). Conclusions: There was a significant relationship between oral health status and behavior in Korean diabetic adults. Further study is needed to evaluate the underlying mechanisms between diabetes mellitus and oral health status.

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.

Purpose : The purpose of this study was to examine the self-rated oral health status of local residents and their quality of life in urban and county areas in an effort to provide information on how to improve their quality of life. Method : The 2015 community health survey data for South Gyeongsang Province(10 urban regions and 10 county areas) were analyzed. Result : The findings of the study were as follows: As for the characteristics of self- rated oral health, there were better self-rated oral health, less chewing difficulty, less use of dentures, higher rate of receiving dental checkups and more scaling experience in the urban communities than in the county areas. Concerning EQ-5D and happiness index by region, the two were higher in the urban regions than in the county areas. In regard to EQ-5D and happiness index by the characteristics of self-rated oral health, better self-rated oral health status and less chewing difficulty led to higher EQ-5D and higher happiness index. And the two were higher when dentures were not used, when more dental checkups were received and when there was more scaling experience. Conclusion : Therefore in order to boost the quality of life of local residents, the preparation of various educational programs is necessary to raise their awareness of health, and they should be provided with a wide range of medical benefits by dispersing medical institutions that are mostly located in urban communities or by expanding public health services in county areas.

Failure of the functions involved in ingestion leads to, not only loss of enjoyment of eating, but also protein-energy malnutrition. Dysmasesis and difficulty of swallowing occurs in various diseases, but aging is a major cause. In the aging society, the proportion of elderly people with dysmasesis and difficulty of swallowing is expected to increase rapidly. Developing foods for the elderly that are easy to chew and swallow is thus required. This study was conducted to develop easily chewable and swallowable foods for the elderly who can crush foods and ingest with their own tongues, but occasionally have difficulty in drinking fluids such as water and tea. Various foods for the elderly with chewing and swallowing difficulties were used for sensory assessment. The sensory panel consisted of 10 dietitians (10 women) in nursing care facilities. The sensory optimal composite recipes were determined by central composite design (CCD). The sensory measurements were significantly different in saltiness (p<0.05), sweetness (p<0.05), and overall quality (p<0.05). The optimum formulation of stir fried anchovy calculated by numerical and graphical methods was 3.74 g of soy sauces and 30.17 g of oligo-saccharides. Stir fried anchovy had a moisture content, hardness and adhesiveness of 76.52%, 2.10, and -1.57, respectively.

This study was performed to investigate the perception and preferences regarding commercial universal design foods (UDF) made with different ingredients. A one-to-one interview was used for data collection and the survey was conducted on 41 elderly people (over age 65; males: 11, females: 30) attending senior welfare centers in Seoul. Twelve UDF samples were collected, which were widely sold in Japan. Majority of respondents prepared meals (53.7%) and ate alone (43.9%), respectively. The preferred cooking level of elderly food was "ready to eat (RTE)" (43.9%) or "ready to heat (RTH)" (43.9%) rather than fresh cut product. In most, the elderly had no problem with chewing-action (90.2%). Generally, food ingredients such as grain, meat, seafood and fruits showed higher preference than vegetable and nuts. Among 12 UDF samples, pumpkin gratin (4.17) and peach flavored jelly (4.27) showed higher preferences among tested samples on a 5-point facial hedonic scale. There were no significant differences in overall preferences of all samples by difficulty in terms of chewing and swallowing of respondents. Demi-glace sauce hamburger and pot sukiyaki were more preferred as age increased (p<0.05).

Background: Raw betel nut (RBN) chewing is an important contributing factor for esophageal squamous cell carcinoma (ESCC), although associated genomic changes remain unclear. One difficulty in assessing the effects of exclusively RBN induced genetic alterations has been that earlier studies were performed with samples of patients commonly using tobacco and alcohol, in addition to betel-quid. Both CDKN2A (at 9p21) and Rb1 gene (at 13q14.2) are regarded as tumor suppressors involved in the development of ESCC. Therefore, the present study aimed to verify the RBN's ability to induce ESCC and assess the involvement of CDKN2A and Rb1 genes. Methods: A panel of dinucelotide polymorphic markers were chosen for loss of heterozygosity studies in 93 samples of which 34 were collected from patients with only RBN-chewing habit. Promoter hypermethylation was also investigated. Results: Loss in microsatellite markers D9S1748 and D9S1749, located close to exon $1{\beta}$ of CDKN2A/ARF gene at 9p21, was noted in 40% ESCC samples with the habit of RBN-chewing alone. Involvement of a novel site in the 9p23 region was also observed. Promoter hypermethylation of CDKN2A gene in the samples with the habit of only RBN-chewing alone was significantly higher (p=0.01) than Rb1 gene, also from the samples having the habit of use both RBN and tobacco (p=0.047). Conclusions: The data indicate that the disruption of 9p21 where CDKN2A gene resides, is the most frequent critical genetic event in RBN-associated carcinogenesis. The involvement of 9p23 as well as 13q14.2 could be required in later stages in RBN-mediated carcinogenesis.
