Effect of treatment dentures on denture space in edentulous patients and its clinical evaluation / 口腔疾病防治

Objective@#To investigate the effect of treatment dentures on changes in denture space in edentulous patients and to evaluate its clinical effect.@* Methods@#Twenty patients with treatment dentures were investigated with a questionnaire and Oral Health Impact Profile (OHIP-14) before and after treatment. The denture space, denture tissue surface, occlusal points, Gothic arch images, mucosal condition, lateral occlusal condition, bite force, retention and stability, patient mastication ability, denture satisfaction, and OHIP-14 score were collected for statistical analysis.@*Results @# After wearing treatment dentures, the denture space significantly improved, the tissue conditioners on the treatment denture gradually began to be distributed, and the occlusal points gradually became symmetrical. The gothic arch images showed that the joints, nerves, and muscles gradually stabilized. The mucosal condition changed to a healthy state. The lateral occlusal conditions were improved. There were also significant differences in the bite force, retention and stability, subjective and objective chewing ability, satisfaction with the denture and OHIP-14 score before and after treatment (P < 0.05). The objective chewing ability was positively correlated with the retention stability of the denture, the subjective chewing ability and the satisfaction of the denture, and it was negatively correlated with OHIP-14.@* Conclusion@#Treatment dentures could help to restore denture space to an ideal condition and improve the oral health of patients. This treatment could also improve the retention and stability of the denture and the chewing ability to improve patient satisfaction. This treatment has clinical application value and promotion potential.

Dental status, oral prosthesis and chewing ability in an adult and elderly population in southern Brazil

OBJECTIVE: The objective of this study was to explore the factors associated with inadequate chewing in an adult and elderly population of a city in the southern region of Brazil. METHODS: This was a cross-sectional study based on a population home-based inquiry (DCH-POP) in southern Brazil. Individuals were interviewed by trained interviewers to create a standardized procedure. In a pilot study, the Questionnaire of Human Communication Disorders (DCH-POP) was created and validated to identify self-reported speech and language, swallowing and hearing disorders. The outcome was dichotomized into either having adequate chewing or not, as assessed by a series of questions about chewing ability. Analyses of absolute and relative frequencies were measured according to the studied variables. A Poisson regression was applied at a significance level of 5%. RESULTS: A total of 1,246 people were interviewed. Inadequate chewing was found in 52 (5.6%) individuals, with a higher prevalence in the elderly (11.8%) than in adults (5.2%). In the final model, the following factors were associated with inadequate chewing: being 61 years of age or older (prevalence ratio or PR=9.03; 95% CI: 1.20-67.91), loss of teeth and use of unadjusted prosthesis (PR=3.50; 95% CI: 1.54-7.95), preference for foods of soft consistency (PR=9.34; 95% CI:4.66-8.70) and difficulty in nasal breathing (PR=2.82; 95% CI: 1.31-6.06). CONCLUSION: Age, oral health status through dental prosthesis, preference for foods of soft consistency and difficulty breathing through the nose were factors associated with chewing inability in adults and the elderly.

Characteristics of the dietary intake of Korean elderly by chewing ability using data from the Korea National Health and Nutrition Examination Survey 2007-2010 / 한국영양학회지

The purpose of this study was to examine the characteristics of the dietary intake of Korean elderly according to chewing ability using data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted during 2007-2010. Among subjects aged 65 years and over, more than half, 54.3% of elderly people, were classified as the difficulty in chewing group (DC). The DC group had lower nutrients and food intakes than those of in the no difficulty in chewing group (NDC). Findings showed that subjects in the DC group consumed fewer foods, especially fruits and vegetables. In addition, the DC group had significantly lower intakes of pan-fried food, stir-fried food, braised food, and seasoned-cooked vegetables, which could not be easily cooked or chewed. On the other hand, the number of soups and stews included in the top 30 largely consumed dishes were higher in the DC group than in the NDC group. No difference in numbers of daily meal/snack intake was observed between the two groups, however, the DC group had lower numbers of side-dishes compared to the NDC group. Fewer side-dishes per meal could be related to lower intakes of nutrients in dietary quality. Findings of this study demonstrated that dietary intake was influenced by chewing ability of elderly Korean people. Therefore, study of factors affecting dietary intake such as convenient cooking methods to decrease cooking time and skills to extend preservation and storage time of foods will necessary. In addition, development of food products and new techniques of cooking considering health status, chewing, and swallowing ability is required for the elderly, followed by establishment of standards for senior-friendly food products.

Comparison of chewing ability and quality of life before and after the dental implantation / 대한치과보철학회지

STATEMENT OF PROBLEM: Recently the populations of patients receiving implant surgery are greatly increase for maintaining oral health. PURPOSE: This study was conducted for implanted patients to assess the chewing ability patient satisfaction level and changes in quality of life before and after the implant surgery. MATERIAL AND METHODS: The current study subjected 109 adult patients, older than 20 years of age, who received implant surgery from December, 2006 to October, 2007 at the 6 dental clinics located at Daegu and Ulsan metropolitan cities. Twice of surveys were conducted for the patients before and after receiving the dental implant surgery. RESULTS: As the motivation of receiving implant surgery, 45.9% of the patients selected the surgery for the chance of "chewing function recovery", and "failure of treatment and complications" was found to be the most worrisome at the time of surgery by recording 38.5%. The satisfaction level before the implant surgery scored 30.37, while the score was increased to 45.01 after the surgery by showing a significant difference before and after receiving the surgery (P < .001). Regard on the surgery, 91.8% of the patients responded as "Satisfy", and 89% of the study subjects responded that they have willingness to recommend the surgery to their families and friends. The chewing ability score measured by using the surveys on edible foods, the score before the surgery was 15.24, while the score was increased to 19.11 after the surgery by showing a significant difference before and after receiving the surgery (P < .001). The quality of life score was also found to be increased to 11.17 after the surgery from 9.99 before the surgery by showing a significant difference (P < .001). CONCLUSION: In a future, the studies on the numbers of implanted loss teeth and the location of tooth loss are necessary, more long-term follow study are needed, and it is thought to be necessary to enlarge the sample size of subjects in conducting the studies.

The effect of denture placement on nutrition status and quality of life in the urban elderly / 대한치과보철학회지

Purpose: This study was conducted to evaluate the effect of denture placement on nutrition status and quality of life in the urban elderly. Material and method: The first survey was conducted from 45 targeted elderly people(25 experimental group, 20 control). In the first survey, information on general characteristics, chewing ability, food intake and nutrient intake, anthropometric measurement, and degree of satisfaction in life were obtained. The second survey was conducted to evaluate the effect of denture placement with same method as the first survey. Results: Before denture placement, there are no statistical significant differences (in general characteristics, chewing ability, nutrient intake, anthropometric measurement, and degree of satisfaction in life) between experimental group and control. But after denture placement, survey shows that there is statistically significant difference in chewing ability between two groups. The experimental group have higher intake of energy, protein, carbohydrate, iron, and vitamin C. in nutrient intake. And after denture replacement, there is significant improvement in degree of satisfaction in life. After denture placement there are significant changes in agitation and attitude toward own aging according to Lawton's factor classification. Conclusion: In short, this study shows that chewing ability improvement of the elderly has strong positive effects to their food intake, nutrient status and quality of life.

The Relationship between Chewing Ability and Health Status in the Urban Elderly who Resides in the House / 영남의대학술지

BACKGROUND: The objective of this study is to evaluate the relationship between chewing ability and health status in order to provide basic information for the development of program which may lead to an improvement of a the elderly health status in urban areas. MATERIALS AND METHODS: The subjects of this study were 128 elderly urban female over the age of 65 who reside at house. The data were collected from May 21 to August 20, 2001, through questionnaires about nutrient intake status, direct measurement of anthropometrics, and oral examinations. RESULTS: In terms of remaining teeth, there was significant negative relationship between age and number of remained teeth. The average number of remained teeth our subjects was 13.1 10.6. About sixty five percent of the subjects were denture users (partial or full dentures) and there was positive relationship between age and the percentage of denture user. There was a significant negative correlation between age and chewing ability. The group that was able to chew had more remained teeth than the other group. CONCLUSION: This study suggests that there is strong positive relationship between chewing ability (remaining teeth) and elderly health status in urban areas, and the importance of preserving original teeth to improve the elderly health status in the public health program.

The Relationship between Chewing Ability and Nutritional Intake Status in the Elderly of Rural Community / 대한지역사회영양학회지

This study aims to examine the relationship between chewing ability and nutritional intake status in the rural elderly. The subjects were 150 rural-dwelling elderly persons(68 males and 82 females) aged 65 years and over in Sungju-Gun, Kyunfsangpookdo. The respondents were interviewed using the questionnaires and measurments taken from a 24-hour recall method from February to April in 1998. Fifty-nine subjects(39.3%) were classified with normal chewing ability and sixty-four subjects(42.7%) could carry out all of the 10 ADL items by themselves. In addition, the group who were able to chew had more teeth and significantly higher ADL scores than the other group(p<0.01), whereas DMF value was significantly lower(p<0.001). The subjects with normal chewing ability also had higher of intakes of energy, protein, fat, carbohydrates, dietary fiber, salt, potassium, niacin, thiamin and riboflavin than in the unable group(p<0.05). As far as daily food intakes were concerned, considerable differences were revealed in the levels of grain and products and vegetables consumed depending on chewing ability(p<0.001). The results of the stepwise and vegetables consumed depending on chewing ability daily living activities and health self-assessment(p<0.05) were the most significant factors for energy intake status.
