Propose: This study was to identify the factors affecting the oral health status in vulnerable elders receiving home visiting health care service. Methods: A total of 444 elderly people over the age of 65 at 33 public health centers in Daegu and Gyungbuk areas were included in this survey. The data were collected by personal interview with nurses using oral health knowledge, behavior, and status questionnaires from the $10^{th}$ to $22^{nd}$ of July, 2012. The data were analyzed with t-test, one-way ANOVA, $Scheff{\acute{e}}$ test, and stepwise multiple regression, using SPSS program. Results: Factors affecting the oral health status were chewing satisfaction with denture 14.5% (${\beta}=.391$, p<.001), denture care (wash with water) 3.2% (${\beta}=-.187$, p<.01), and types of health insurance (medical aid type1, 2) 1% (${\beta}=-.111$, p<.05). The factors explained 18.7% of variance in the oral health status of vulnerable elderly subjects. Conclusion: The results of this study indicate that in order to improve the oral health status of vulnerable elders, it is necessary to provide oral health education that includes the proper usage of denture to elders who receive home-visiting care.

Purpose. To investigate the differences in the frequency of post-fitting denture check-ups based on gender, age, insurance status, denture arch, and type among patients aged 65 and above. Methods. This research analyzed 988 patients from National Health Insurance Service Ilsan Hospital's Department of Prosthodontics, who had denture fittings over the last 10 years. Variables including gender, age, insurance status and type, denture arch, and denture type were assessed. Statistical analyses were performed at a 5% significance level. Results. The study incorporated 988 dentures, revealing a median of 3 check-ups post-fitting. Male patients significantly had more visits than females (P = .017), and those with full metal dentures visited significantly more than those with partial dentures (P = .005). Other variables were not significantly influential on the post-fitting check-up frequency. Conclusion. Within this study's confines, an increase in denture adjustment sessions was observed for male patients and those with full metal dentures.

In Korea, there has been a rapid increase in the number and proportion of elderly people, especially in rural areas, due to improvements in the standard of living and medical technology. One of the main health problems for the elderly people is dental health, which can cause nutritional and health problems. Thus, in this study, the dental health status and health status in relation to nutritional intake were analyzed. A total of 155 rural-dwelling elderly people (68 males, 87 females) over the ages of 65 participated in this study. The subjects were classified into three groups; the no denture no teeth group, denture user group, and natural teeth group. The dietary intake, biochemical health status, and anthropometry were evaluated. Can-pro 3.0 was used to assess dietary intakes and the SPSS 12.0 program was used for statistical analysis. The results showed that the natural teeth group had better nutritional and dietary intake status than the no denture no teeth group. The dietary assessment showed that there were differences in food intakes among the groups, which depended on their dental health status. In conclusion, dietary management is required for the elderly since each group has a different ability to chew food depending on their dental health status. In addition, the elderly will need different therapeutic diets because of the high prevalence of chronic degenerative diseases.

This study examined the oral health-related quality of life of the elderly using the oral health index and dental prosthesis status, and explored methods to improve the oral health status. The data collected from 'The fifth Korean national health and nutrition examination survey 2010' were analyzed. The subjects were 2273 elderly people, aged 65 years or older, who had completed an oral examination, health questionnaires and nutrition examination. Statistical analysis was done using the SPSS 22.0 for Windows. Frequency analysis, multiple regression analysis and structural equation model were used for statistical analysis. The general characteristics, oral health index and dental prosthesis showed differences in the subjective oral health status associated with as age, ST, FS-T, T-Health, maxillary crown needs, maxillary denture needs, mandibular denture needs, chewing status associated with the income level, FS-T, maxillary crown needs, maxillary denture needs, mandibular denture needs, speaking status associated with the ST, T-Health, maxillary implant status, and maxillary denture needs. In conclusion, both the oral health index and dental prosthesis needs affect the oral health related quality of life of the elderly. Governments should implement a variety of oral health programs and dental prosthesis policies to improve the quality of life related oral health of the elderly.

Few reports regarding the effect of government paid denture project for low-income elders evaluated by the participating dentists are available despite the project was launched in 2002. Thus, this study investigated the effect of the project evaluated by the participating dentists and suggested public health policies for the better development of the project. Survey questionnaire regarding desire to continue participation, motivation of the participation, list of complaints, wish of the payment increase, and wish of the abutment crown increase were completed by 117 dentists in Seoul and Pusan. 78.6% of them desired to continue the participation while 16.2 % of them did not. When the motivation of participation was the service for the society, they tended to show the desire of continuing participation. Half of them were satisfied with the current payment(50.4%), while the other 47.9% did not. Complicated oral health status(48.7%), poor cooperation of patients(8.5%) and too frequent after cares low payment(6.8%) were complained. Payment increase compensating the addition of preprosthetic procedures for the complicated oral health status and the after cares was desired. Also, more thorough education regarding the denture project for the patients by the public health center is needed to alleviate the inconvenience of the participating dentists.

The purpose of this investigation was to evaluate the mouth preparation and design of removable partial dentures. A total of 187cases for the prefabricated partial denture frameworks in both maxillary and mandibular semi-dentulous situations (66 cases and 203 cases) was selected from this study. The evaluations of mouth preparation and design observed here involved the classification of edentulous spaces, status of abutment splinting with location, design of direct retainer and structure of maxillary major connector according to the incidence of both dental arches, ages, sexes and segment of semidentulousness. The analyzed results were as follows: 1) The order of frequency rate in removable partial denture construction was Class II (50.27%), Class I (36. 90%), Class III (10.69%), and Class IV (2.14 %). 2) The distribution on design of maxillary removable partial denture prosthesis was 33.22% and 64.11% in mandibular removable partial denture prosthesis. 3) The age distribution of removable partial denture prosthesis was prominent after40 years (41.71%). 4) The design pattern of maxillary major connectors was in order of anteroposterior bar, single palatal bar, palatal strap, U-shape connector. 5) The design pattern of direct retainer was in order of Aker's clasp, I-bar clasp, backaction clasp, cuspid universal clasp. 6) The abutment for partial denture clasp splinted between premolar and premolar and its frequency rate revealed 53.44%. 7) It seemed that the location and design of the indirect retainer showed accepatble limit.

The objective of preventive dentistry is the maintenance of a healthy dentition for the life of a patient. Unfortunately, if an individual has not received the benefit of a comprehensive program of preventive dentistry and has finally reached the edentulous state, as a consequence, he receives a set of complete denture. Dentures are mechanical devices and subject to the principles of mechanics. In some cases, the general health and nutritional status of the patient are felt to be the causative factors. But, the most important thing in residual ridge resorption is felt to be caused by the unequal distribution of functional forces. This study was to analyze mandibular stresses of complete denture occlusion by three dimensional finite element method. The results were as follows ; 1. As deformation and stress distribution of the complete denture of the mandible were concentrated on the upper lingual side of the mandible, alveolar ridge resorption of the mandible occurred from lingual side to labio-buccal side. 2. Analyzing by three dimensional F. E. M., the mandible is a very effective form for tolerating stress and deformation biomechanically. 3. According to the concentration of stress distibution in the upper buccal side of the lower posteriors, buccal shelf area must be a primary stress bearing area in the lower complete denture. 4. Lower complete denture moved horizontally to the balancing side under lateral occlusal force. 5. Bilateral balanced occlusion should be constructed in the complete denture for denture stability, especially in the protrusive movement. 6. Physical property of the denture base material was as important for stress distribution in the denture base as or even more than that in the mandible. 7. Impression technique is very important because of most of stress was concentrated between them due to close contact of the mandible and the denture base.

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 $13.1{\pm}10.6$. 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 purpose of this study was to investigate the oral health condition and dental treatment need of low socioeconomic elderly people. A total of 116 elderly people who visited Boramae Hospital were evaluated with oral examination and panoramic radiogaph. The results showed that the most expecting treatment of low income aged people was removable partial denture. It was very clear in the age group of 70-84. In the age group under 70, most of the patients wanted prosthodontic tratement using fixed partial denture or crown. As the result of this study, elderly people with low socioeconomic status under age 85 needed removable partial denture or fixed prosthesis than complete denture. It is necessary to develop a more expanding and customized Senile prosthetic restoration program.
