The masticatory muscle disorder is the most common problem that patients with temporomandibular disorder often complain. For such complaints, treatment is directed towards reducing hyperactivity of muscles or effects of the central nervous system. However, if nonspecific occlusal change or pain persists, it is necessary to consider that muscle weakness might be the cause of the persistence of temporomandibular disorder. Stabilization of occlusion and improvement of the pain symptoms were achieved in both cases through the chewing gum exercise. This exercise may enable masticatory movements done in normal function by using muscle engram and achieve reinforcement of the masticatory muscles with balanced, simultaneous contacts of the teeth. In addition, it may be a viable method for treating temporomandibular disorders that do not respond well to conventional mandibular stabilization therapies.

Periodontal disease accompany the inflammation around periodontal tissue and generally periodontal destruction is followed, This destruction often makes the molar teeth have furcation defect. And to treat molar furcation involvement, resective surgery such as root resection and ostectomy and regenerative procedure such as guided tissue regeneration were introduced. Also implant can be considered as one of the good treatment methods, Among these treatment alternatives, root resection can be considered as a good procedure in the point of saving one's natural teeth or amount of cost. Therefore the purpose of this article is to evaluate root-resected teeth which were done at least 2 years ago. 70 root-resected teeth in 58 patient who visited Kyungpook National University Hospital were included in this study. They were evaluated by two clinical method. One is subjective evaluation and another is objective evaluation. To evaluate subjective outcome, 58 patients answered to the questionnaire if they experienced tooth extraction, bleeding, swelling, pain, mobility and chewing problem. To evaluate objective outcome, 28 teeth was evaluated according to Langer's criteria. The subjective result showed 82% of success rate and 18% of failure rate. 13 of 70 teeth showed discomfort and were considered as failure, which include chewing problem (39%) and pain (23%). The objective outcome showed that 4 failure (14% failure rate) which were 2 cases of bone loss by periodontal problem, one endodontic problem and one untreatable caries. By these limited results, some of clinical consideration in root resective procedure can be suggested. Periodontal support and less occlusal loading on resected tooth should be evaluated before the procedure, moreover, good oral hygiene is essential. When these factors are considered carefully, the root resection may produce predictive outcomes in the treatment of furcational involvement.

This study was perfomed to investigate the prosthodontic and periodontal status of the abutment teeth in distally extending bridges(DEBs) (78 cases) and removable partial dentures(RPDs) (43 cases) for 122 patients (55 males and 57 females) visiting department of Periodontology, Seoul National University Hospital. The average wearing periods were 67.8 months for DEBs and 66.4 months for RPDs. 38.4% of the patients in DEBs and 35.9% in RPDs complainted of chewing discomfort and 22.6% and 24.4% were not chewing on the prosthodontically - treated sides, respectively. In DEBs, when the restoration for 2nd molar supported by 1st molar & 2nd premolar was grouped to type 1, 1st molar supported by 1st & 2nd premolars was type 2, and 1st & 2nd molars supported by 1st & 2nd premolars was type 3, there was a significant differences only in the tooth mobility score among clinical parameters (type 2>type 1>type 3). In RPDs, when bilateral free-end case was grouped to type 1, and unilateral case was type 2, there was a significant difference in the Gingival index (type 1>type 2). In DEBs, 62.8% of restoration were overcontoured, 72% had interproximal space closures, 30.5% overextended pontics and 86.6% overhanging margins. In RPDs, 24.4% of the restorations were overcontoured, 45.5% had interproxinal space closures and 58.3% overhanging margins. From these results of this study, periodontal problems caused by prosthodontic defects were considered to be contributing factors in chewing discomfort.

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).

Smoking is recognized as a health problem worldwide and there is an established tobacco epidemic in Saudi Arabia as in many other countries, with tobacco users at increased risk of developing many diseases. This cross sectional study was conducted to assess the prevalence of oral mucosal, potentially malignant or malignant, lesions associated with tobacco use among a stratified cluster sample of adults in Jeddah, Saudi Arabia. A sample size of 599 was collected and each participant underwent clinical conventional oral examination and filled a questionnaire providing information on demographics, tobacco use and other relevant habits. The most common form of tobacco used was cigarette smoking (65.6 %) followed by Shisha or Moasel (38.1%), while chewing tobacco, betel nuts and gat accounted for 21-2%, 7.7%, and 5% respectively. A high prevalence (88.8%) of soft tissue lesions was found among the tobacco users examined, and a wide range of lesions were detected, about 50% having hairy tongue, 36% smoker's melanosis, 28.9% stomatitis nicotina, 27% frictional keratosis, 26.7% fissured tongue, 26% gingival or periodontal inflammation and finally 20% leukodema. Suspicious potentially malignant lesions affected 10.5% of the subjects, most prevalent being keratosis (6.3%), leukoplakia (2.3%), erythroplakia (0.7%), oral submucous fibrosis (0.5%) and lichenoid lesions (0.4%), these being associated with male gender, lower level of education, presence of diabetes and a chewing tobacco habit. It is concluded that smoking was associated with a wide range of oral mucosal lesions, those suspicious for malignancy being linked with chewable forms, indicating serious effects.

This study examined the sociodemographic factors, health-related habits, chronic diseases, dietary habits, and nutrient intake according to the self-rated health status in a group aged over 65 years by analyzing the nationally representative Korean survey data. A total of 1,510 subjects were analyzed among the participants of the 2016 Korean National Health and Examination Survey (KNHANES). Statistical analyses for complex samples were performed using the SPSS software package (version 19.0) The study subjects were divided into two groups (healthy group vs. unhealthy group) based on their self-rated health status. The percentage of the healthy group was 66.5%. Gender, age, education level, household income, job (P<0.001, respectively), marital status, and basic living allowance (P<0.05, respectively) were significant sociodemographic variables of the self-rated health status. Alcohol consumption (P<0.01), aerobic physical activity, stress, quality of life, not feeling very well, depression and activity restriction (P<0.001, respectively) were also significant health-related variables of the self-rated health status. Blood glucose, anemia (P<0.05, respectively), and chewing problems (P<0.001) were significant chronic disease-related variables of the self-rated health status. Adequate intakes of protein, dietary fiber, phosphorus, thiamin, niacin, vitamin C (P<0.001, respectively), calcium, sodium, potassium (P<0.01, respectively), iron, vitamin A, and riboflavin (P<0.05, respectively) were also significant variables of the self-rated health status. In complex samples multiple logistic regression analysis, the self-rated health status was influenced significantly by the aerobic physical activity (P<0.01), stress level (P<0.05), depression (P<0.001), quality of life (P<0.001), not feeling very well (P<0.001), activity restriction (P<0.001), chewing problem (P<0.05), and adequate intake of iron (P<0.05). These results suggest that activity restriction, mental health, adequate iron intake, and physical activity may be associated with the self-rated health status in the elderly.
