Purpose: This study utilizes big data from the 8th (2021) National Health and Nutrition Examination Survey to determine first, the relationship between chewing discomfort in the elderly and some systemic diseases and second, whether oral diseases and oral health problems are related to systemic diseases. Since this may have an impact, we aim to provide basic data to facilitate the expansion and emphasize the importance of integrated health management education. Methods: Original data from the 8th (2021) National Health and Nutrition Survey, conducted by the Korea Centers for Disease Control and Prevention, were analyzed using SPSS Version 21.0 (IBM). A complex sample frequency analysis was conducted to confirm the general and health-related characteristics of the study subjects, and a complex sample cross-analysis was conducted to determine chewing discomfort according to both general and health-related characteristics. Complex sample multiple logistic regression analysis was conducted to determine the effect on chewing discomfort. Results: In order to analyze the factors that affect chewing discomfort, the general characteristics that showed significant differences in chewing discomfort were adjusted for age, personal income, education level, basic livelihood security, high blood pressure, subjective health status, and subjective oral health. It was found that the condition had a statistically significant effect on chewing discomfort. Conclusion: The findings of this study demonstrate that high blood pressure, subjective health status, and subjective oral health status affect chewing discomfort; hence, measures such as developing and operating programs to improve national oral health are needed. We hope that our study will be used as basic data for research into chewing discomfort and systemic diseases in the elderly.

Objectives: This study aimed to identify factors related to oral health and depression in Korean adults and contribute to the development of a mental health program to improve depression through oral health management. Methods: Data was obtained from the 2021 Korean Community Health Survey. The chi-square test was used to determine the differences in depression experience relative to general participant characteristics and their oral health. To determine the odds ratio and 95% confidence interval, multiple logistic regression analysis was used. All statistical analyses were performed using the SAS software (version 9.4). Results: The results suggest that depression may be influenced by gender, age, household generation, drinking habits, subjective health level, moderate to high exercise, breakfast, high blood pressure, diabetes, subjective oral health level, chewing discomfort, and tooth brushing. An increasing level of depression was associated with decreasing subjective oral health level (1.34 times), uncomfortable chewing (3.08 times), and frequency of toothbrushing after lunch or before going to bed (1.23 times and 1.58 times, respectively). Conclusions: Our study confirmed a close relationship between oral health and mental health. In developing health programs for improving depression, appropriate oral health care should be considered.

This study was performed to investigate the masicatory efficiency in patients with temporomandibular disorders (TMDs), especially internal derangement of temporomandibular (TM) joint. For this study, 26 patients after treatment and 33 dental students who had no signs and symptoms of TMDs were selected as the patients group and as the normal group, respectively. Mean treatment duration of the patients was. 5.1 months. Verbal rating scale(VRS) and Visual analogue scale(VAS) were used for recording of subjective symptoms. Treatment index (VAS Ti) derived from VAS was calculated for evaluation of treatment progress and clinical examination was also performed for objective symptoms. BioEGN(Bioresearch Inc., Milwaukee, USA) was used for observation chewing movement pattern on peanut, caramel candy, and gum chewing. Chewing time in second and symptoms after chewing were recorded, and pattern of chewing stroke between in affected side and in contralateral side or between in right in left side were compared, and especially, gum chewing pattern between before and after treatment were also compared in the patients group. The data obtained were analysed by SPSS windows program and the results of this study were as follows : 1. Subjective symptoms evaluated by VAS showed no difference between the two groups, but those by VRS showed slight difference for TM joint pain, head not neck symptoms, and chewing ability. 2. There were no difference at the level of subjective symptoms between the subgroups divided by treatment duration of five months in the patients group. However, value of VAS Ti of pain was higher in subgroup of long treatment duration than that of subgroup of short treatment duration. 3. There were no difference in chewing time for peanut or caramel candy between the two groups, but on caramel candy chewing, the patients group complained slight discomfort after swallowing. Chewing velocity and range of motion on gum chewing after treatment in the patients group showed significant difference and greatly improved compared to those to before treatment, and which were not differ from those of normal subjects. In conclusion, treatment of temporomandibular disorders about for five months would greatly improve chewing ability and movement pattern in most of the patients with TMDs.

The purpose of this study was to identify chronic diseases and oral health care behaviors in 65-year-old individuals and to determine the factors that influence masticatory mobility. The raw data from the 8th National Health and Nutrition Examination Survey in 2020 were utilized to analyze factors associated with chewing discomfort in 1,278 elderly Koreans. Using IBM SPSS Statistics 27.0, we conducted complex sample cross-analysis to examine the difference in chewing discomfort based on general characteristics, chronic diseases, and oral health care behaviors. Additionally, we performed complex sample multiple logistic regression analysis to identify the factors associated with chewing discomfort. As a factor influencing chewing discomfort, unmet dental care was 3.33 times higher (p<0.001), and subjective oral health was 0.18 times more likely to be moderate (p<0.001) and 0.48 times more likely to be good (p<0.001) lower. In the case of arthritis, the level of chewing discomfort was high (OR=1.08, p=0.694), but there was no significant difference. As a result of the aforementioned factors, it is believed that there is a need for policies and systems to provide dental care to the elderly before their oral health deteriorates. Additionally, tailored oral health promotion programs should be implemented.

Objectives: In this study, both subjective and objective levels of oral health were used to identify the relationship between oral health inequalities. Methods: Korean National Health and Nutritional Examination Survey data from 2013 to 2015 were combined to create an analysis plan. Oral health questions categorized as subjective oral health conditions and oral health-related diseases used dental tissue disease status as data measured by the Community Periodical Index(CPI) and decayed, missing, filled teeth(DMFT) experience. Other data on oral health behaviors such as toothache experience, the frequency of toothbrush use, chewing problems, oral examination status, and unmet dental care needs were classified and analyzed according to the socioeconomic level. Data were analyzed using frequency and cross analyses, and the statistical significance level was set at 0.05. Results: It was found that higher the economic and educational level, better was the subjective oral health, lower the CPI, lower the experience of toothache, higher the frequency of toothbrush use, lower the number of people having chewing problems, and higher the frequency of oral checkups. Conclusions: Oral health inequality exists among social classes. It is suggested that continuous research and efforts be carried out to promote oral health while considering socioeconomic and educational levels. Further, active government efforts will be needed to address polarization by social class.

Objectives : The purpose of this study was to evaluate the chewing ability, oral-health related quality of life and factors in periodontal disease patients. Methods : Subjects were 111 patients having peridontal disease in 10 dental clinics in Busan and Gyeongsangnamdo. Questionnaire survey was carried out from July to August 2010. Questionnaire consisted of demographic characteristics, oral health factors, chewing ability and quality of life. Data were analyzed by descriptive analysis, t-test, ANOVA, correlation analysis, and multiple regression analysis using SAS(Ver 9.2) set at p<0.05. Results : Chewing ability was $44.85{\pm}8.8$, and their quality of life was $41.7{\pm}8.8$. Low level of quality of life was closely related to those factors as education, missing of more than 5 posterior teeth, certain subjective periodontal symptoms including swollen gums, sore gums, drifting gums, bad breath and toothache. The effective factors to the quality of life was chewing ability, bad breath and toothache. Conclusions : Chewing ability and quality of life were closely related each other. To enhance the quality of life, chewing ability should be improved. Proper treatment and effective method of management should also be properly considered to prevent the subjective periodontal symptoms and to minimize tooth loss.

PURPOSE. Prevention of xerostomia and stress is important to prolong healthy life expectancy and improve the quality of life. We aimed to investigate the effects of tongue rotation exercise for increasing salivary secretions and stabilizing salivary stress hormone levels. MATERIALS AND METHODS. Twenty four participants without subjective oral dryness were enrolled. The exercises comprised tongue rotation exercise and empty chewing. The salivary stress hormone level was measured using a Salivary Amylase Monitor. Unstimulated whole saliva volume and salivary amylase activity were measured before tongue rotation exercise or empty chewing and subsequently 5, 10, and 15 minutes after these exercises. Differences in the rates of change of unstimulated whole saliva volume and salivary amylase activity were analyzed by repeated measure analysis of variance. RESULTS. Statistically significant differences among the rates of change were not observed after empty chewing for unstimulated whole saliva volume and salivary amylase activity at the four measurement times. However, the rate of change of unstimulated whole saliva volume and salivary amylase activity were statistically significantly different among the four time points: before the tongue rotation exercise and 5, 10, and 15 minutes post-exercise (P<.05 and P<.01, respectively). CONCLUSION. Tongue rotation is effective in increasing saliva secretion, reducing stress, improving oral function, and extending healthy life expectancy.

본 연구는 근육의 경도와 탄성도를 측정하여 교근 피로에 대한 물리치료의 효과를 정량적으로 평가하고자 하였으며, 측두하악장애 치료에 가장 흔히 사용되는 물리치료이면서 작용기전은 서로 다른 세 가지 치료법인 전기침자극치료(EAST), 극초단파(Microwave diathermy), 저수준레이저치료(LLLT)의 효과를 비교하였다. 실험을 위하여 건강한 20대 지원자 10명을 선정하여, 교근의 전부와 하부의 근육 경도와 탄성도를 촉각센서로 측정하였다. 실험적으로 교근 피로를 유발하기 위해 피검자가 VAS (0 to 10) 5 이상의 통증을 느낄 때까지 껌을 씹게 하여 근육 변화를 조사하였으며 치료 없이 15분간의 휴식을 준 다음 다시 검사하여 물리치료 후의 효과 비교를 위한 대조군으로 사용하였다. 하루 간격으로 사흘에 걸쳐 동일한 시간 동안 껌을 씹게 한 다음, 물리치료 한 가지씩을 매일 시행하였으며 3가지 물리치료법의 적용 순서는 무작위로 하였다. 껌 저작 전, 직후, 15분 후, 각각의 물리치료 시행 후에 근육 경도와 탄성도 측정과 함께 피검자들이 느끼는 근육의 피로도를 VAS로 평가 하도록 조사하였다. 실험 결과, 저작측에서만 껌 저작 직후와 15분 후에 근육경도의 증가와 탄성도의 감소가 관찰되었으며 (p<0.05) 비저작측에서는 유의한 차이가 없었으나 VAS는 저작측과 비저작측 모두에서 증가하였다(p<0.05). 껌 저작으로 인해 변화되었던 근육경도와 탄성도는 전기침자극치료나 극초단파 치료 후에 효과적으로 회복되고 VAS가 감소했으나(p<0.05) 저수준레이저 치료 후에는 유의한 변화를 보여주지 않았다. 이상의 결과로 보아, 편측 저작은 저작측 근육의 경도를 증가시키고 탄성도는 감소시키는 반면, 비저작측에서는 변화가 없는 것을 알 수 있다. 또한 전기침자극치료와 극초단파치료는 모두 근육의 경도를 감소시키고 탄성도를 증가시켜 근육의 피로를 감소시키는데 효과적인 치료법인데 반해 저수준레이저치료의 효과는 미약한 것으로 판단된다.

Objectives : In this study, we investigated the correlation of mental-and oral-health status with periodontal disease. Ultimately, we sought to make a positive contribution to the promotion of periodontal health and the prevention of periodontal disease. Methods : This study was analyzed using the data of KNHANES 2013-2015. The participants of this study were between 20 and 64 years old. The final selection was 1,512 adults. Results : Participants with a sleeping time of less than 6 hours and those who recognized stress showed higher periodontal disease. Number of decaying teeth, oral-health status, toothaches, and chewing problems were associated significantly with periodontal disease. To investigate the effects of general characteristics and mental and oral-health status on periodontal disease, a logistic regression analysis was conducted. Sex, age, education level, smoking status, oral-health status, and chewing problems were variables that affected periodontal disease. Conclusions : This study showed that mental-and oral-health status is closely related to periodontal disease. Therefore, it is expected that this will be used as basic data to effectively improve periodontal disease in adults.
