Purpose: This study was conducted to investigate the wearing dentures status of the elderly and understand the relationship between demographic sociological properties, oral health care habits, lifestyle, and whether they wears dentures or not. Methods: In a surveying of 349 elderly who lives in Daegu and Kyung-pook, following results are obtained. Results: Wearing dentures rates of the aged are 58.5%. The more the aged is female(p=0.025), elderly(p=0.000), a low education level(p=0.000), no job(p=0.006), and a solitary person(p=0.016) the higher rate they wears dentures. The more the aged brushes their teeth after each meal(p=0.029) and uses the oral health devices(p=0.000) the lower rate they wears dentures. The more the aged have dinner alone(p=0.009), do not kept up with the exercises (p=0.000), and would like to dine off a soft food(p=0.000) the higher rate they wears dentures. Conclusion: This study showed that an old people's condition of oral health care who live in Daegu Kyungpook is very serious. Therefor not only an elderly but other aged people is need of constant and organized education for taking their oral health care habits and changing their lifestyle.

Background: For the elderly, masticatory function is one of the most important oral functions and the masticatory ability is related to the wearing of dentures. Many older people wear dentures for their masticatory function, but a significant number of older people who use dentures have found that they feel uncomfortable when performing their daily activities, such as performing masticating functions or talking. Objects: The purpose of this study is to investigate how the forward head posture (FHP), respiratory function and thickness of masseter (MS), and sternocleidomastoid (SCM) are affected by the presence or absence of dentures in the elderly, and what kind of correlation there is between these variables. Methods: The study was conducted on 11 patients in the normal group and 13 in the denture group. The participant's cognitive ability was evaluated using Mini-Mental State Examination Korean (MMSE-K), and the FHP was evaluated by measuring the craniovertebral angle (CVA). The thickness of the MS and SCM muscles were measured using ultrasound, and respiration was measured with a spirometry. As for the statistical method, the correlation of each variable was investigated using Spearman's correlation coefficient. Results: In the normal group, there was a significant correlation between forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) (p < 0.001), and in the denture group, FVC and FEV1 (p < 0.001), maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) (p < 0.001), CVA and Lt. MS (p = 0.012). Conclusion: CVA and Lt. MS of the denture group have a high negative correlation, it is related that the thickness of MS may be thick when the elderly wearing dentures are FHP.

This experiment was to find out the complacency of wearing dentures and the linkage to the quality of life style of oldsters 60 years old and over. 122 numbers of oldsters who came to aid to the health center were put to survey. This was taken place within the areas of Deajun, Koonsan, Mooju and Jinahn, thus procured the following result. 1. The length of edentulous period of 1-6years of oldsters aged around 60s showed 26.0%. The oldsters with edentulous period of over 7years aged in the 70s showed 26.1 % and 56.0% on oldsters aged in the 80s. This shows that as the age increases the edentulous period lengthens. (P<0.05) The length of time of using the denture shows. llyears or over on women 41.9%, less than 6years on men 71.4% as the highest rate. 11 years or over on towns/subcounty show 57.5%, small and medium cities more than 1 year 63.6%, less than six years also 63.6% and Kwangyuk city 47.6%. 2. The complacency on medical treatment of dentures was highest in Kwangyuk city of 61.3%, compared to towns/subcounty of 50.8% and small and medium cities of 33.3%. (P<0.05) 3. The complacency on mastication and pronunciation appears, 2.74% in Kwangyuk city, 3.10% in towns/ subcounty which is higher than the small and medium cities showing 1.09% on average. Satisfaction rate tends to be higher as the length of time of using the denture is longer. 4. Inconvenience on eating habits caused by dentures were felt by women. Wanting to get a new denture was 25.6% by women showing much higher rate than that of men which is 2.8% by men. (P<0.05) 5. The complacency of change in their life style after wearing the dentures were higher in Kwangyuk city of 64.5% whereas it showed 27.0% in towns! subcounty and 16.7%in small and medium cities.

The movements of oral surrounding muscles, lips, and tongue play a very important role while masticating, swallowing, and speaking. In case of the edentulous patient wearing dentures as well, every movement of the tongue can be seen almost the same as that of the dentulous jaw. The crushed food during mastication is swallowed and sent to pharynx. At this course, the contact of the posterior portion of tongue with dentures affects the stabilization of denture. The retention and stability of the complete dentures are related with buccinator muscles of buccal parts, lips in front, and tongue of the lingual sides. Strack(1946) insisted that the arrangement of artificial teeth in the same place as that of the natural dentition is the best way to maintain the stability of denture. In this report, I would like to introduce the several advantages of a new impression method taken simultaneously, and its procedures and clinical cases.

PURPOSE. The purpose of this clinical study was to evaluate the frequency and type of prosthetic complications in relation to type and properties of removable dentures and to investigate the influence of these complications and several data about the existing dentures on patient satisfaction. MATERIALS AND METHODS. Ninety nine patients (44 males and 55 females) wearing removable dentures have been included in the study. The complications of the patients were recorded; patient satisfaction was determined with a Visual Analog Scale (VAS) and the relationship of complications and patient satisfaction with several data about the dentures such as denture age, type of denture, centric relation and vertical dimension was investigated. Kruskal Wallis, Mann Whitney U and Chi square tests were used for statistical analyses. The results were evaluated statistically at a significance level of $P$ <.05. RESULTS. Need for addition of artificial teeth for dentures with correct centric relations was found to be significantly lower than dentures with wrong centric relations ($P$ <.01). Loss of retention, ulcerations and high vertical dimension affected the VAS chewing ability scores negatively and ulcerations affected the VAS phonation scores negatively ($P$ <.05). CONCLUSION. Considering the results of this study, it can be concluded that loss of retention, ulcerations and high vertical dimension caused patient dissatisfaction. Additionally, dentures with wrong centric relations caused need for addition of artificial teeth.

Purpose: In order to validate empirically the theoretical model of this study subjects, who were limited in Andong gun, Youngyang gun, Uiseong gun, Bonghwa gun, Chilgok gun, Cheongsong gun according to residence-specified distribution and over aged 65, were focused to the elderly in rural areas with geographical characteristics where they have difficulties in accessibility of dental facilities and dental care. Methods: The collected data were analyzed by the SPSS 19.0 program. First, the frequency analysis was performed for each independent variable and the dependent variable. Second, reliability analysis and correlation analysis were conducted for daily living skills and Biomedical Vigilance. Third, multivariate analysis was performed in terms of and the post-administration management. Fourth, multiple regression analysis was performed to identify the factors affecting the post-management of dentures and the period of using dentures. Results: By results of the multiple regression analysis, the elder the subjects are(${\beta}$ = 0.03), the lower their income activities are(${\beta}$ = -0.18), the smaller their monthly allowances are(${\beta}$ = -0.16), the worse their daily activity skills are(${\beta}$ = -0.12), the more they were mounted their dentures by an unlicensed contractor(${\beta}$ = 0.07), and the more they cost to their dentures(${\beta}$ = 0.14), the longer the period of use dentures are. And the beneficiaries of Basic Livelihood Security(${\beta}$ = -0.14) who got free denture business are shorten the period of using dentures. According to multiple regression analysis for post management of dentures, the independent variables like the health education(${\beta}$ = 0.24), smoking(${\beta}$ = -0.18), periodic oral examination(${\beta}$ = 0.13), dentures mounted by an unlicensed contractor(${\beta}$ = -0.13) are shown statistically significant results. In that study subjects are taking part in health education and non-smokers, they are likely to have more chances to post management for their dentures like periodic oral examination. However the subjects who were weared their denture by an unlicensed contractor get less chance to post management for their dentures. Conclusion: As the elderly who want to wear denture are increasing due to the denture insurance for the elderly, the need for oral health education for the elderly is an urgent request, especially continuos education for the way of use their dentures and follow-up management for the elderly who were already mounted their dentures. And also, the need for more systematic researches is requested for securing objective data.
