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.

Implant treatment has become the treatment of choice to replace missing teeth in partially edentulous areas. Dental implants present different biological and biomechanical characteristics than natural teeth. Occlusion is considered to be one of the most important factors contributing to implant success. Most literature on implant occlusal concepts is based on expert opinion, anecdotal experiences, in vitro and animal studies, and only limited clinical research. Furthermore, scientific literature regarding implant occlusion, particularly in implant-supported fixed dental prostheses remains controversial. In this study, the current status of implant occlusion was reviewed and discussed. Further randomized clinical research to investigate the correlation between implant occlusion, the implant success rate, and its risk factors is warranted to determine best clinical practices.

I choosed two hundred person of national female dental technician at random and researched the questional of 143 persons. So I came to the following conclusions. Most of them were in charge of porcelain part in dental laboratory and were mostly doing build-up of Porcelain part. When they choosed laboratory work, generally they inclined to choose their relatives and professor's introduction and because of their home they worked there. In these questions, laboratory work is the proper job for a women. Most of them thought that it was fairly good job. Many maiden ladies wanted to keep engaging in dental laboratory after they got married. In these questions, they want to open dental laboratory in the future, 40% of female dental technician want to do. They have alternative and positive ideas about dental prosthesis work.

Dental implants should be placed at ideal sites for implant-supported restorations. For a patient with insufficient residual ridge, mouth preparation including surgical intervention can be indicated to establish a soft and hard tissue environment favorable for a definitive prosthesis. Prosthodontic design based on computer-guided surgery and computer-aided design-computer-aided manufacturing (CAD-CAM) provides a visual blueprint allowing a clinician to assess the necessity of such a surgical intervention beforehand. In this case, a definitive restoration was planned and made via a CAD-CAM system according to the patient's oral status before treatment, simulated surgical interventions and serial provisional restorations. Based on the planning, a guided template was made and the implants were installed with bone augmentation using the template. Customized abutments, the first and the second provisional restorations were designed and fabricated by CAD-CAM. The definitive restorations were digitally made following the shape of the second provisional prostheses, which were confirmed in the patient's mouth. The patient was satisfied with the masticatory, phonetic and aesthetic functions of these definitive prostheses.

Purpose: We studied to decide the operative indication of the metastatic tumor in pelvis according to the oncologic results, the Eastern Cooperative Oncologic Group (ECOG) performance status and complication. Materials and methods: From May 1994 to May 2003, 9 patients who were performed on palliative treatment and 10 paitents on operative treatment due to metastatic tumor of pelvic bone were investigated. On palliative/operative group, the mean age of patients was 57.6/48.0 years old and the ratio of male to female was 5:4/7:3. Primary origins were 3 cases from kidney, 3 from cervix and 2 of lung, 2 of myeloma, 2 of Non-Hodgkin's Lymphoma, and 1 from breast, bladder, testis, prostate, stomach, liver and retroperitoneal leimyosarcoma respectively. The palliative treatment was performed in 5 cases with radiotherapy, 1 with chemotherapy, 2 with combined chemo-radiotherapy and 1 with percutaneous cementation. The operative methods were 1 case of bone cement insertion after curettage, 2 of Girdlestone with internal hemipelvectomy and 7 of reconstruction after wide excision. Reconstructions were done.: 1 case of bone cementation, 5 of autograft prosthesis composite with irradiation or pastuerization and 1 of saddle prosthesis. We have observed the oncologic results, the ECOG performance status and complication. Results: The oncologic results of palliative/operative groups are NED 0/1, AWD 2/6, DOC 1/2 and DOD 6/1. The ECOG performance status was changed from 1.5 into 4.3 in palliative group and from 2.6 into 2.2 in operative group. The complications were 3 cases of the prosthesis failure and 2 of infection. Conclusion: The indication of operation of metastatic pelvic tumor is decided in consideration of the patient's condition, the grade of malignancy in primary tumor and the life expectancy.

Purpose: The recent proliferation of the aging population, oral health care is closely related to the mental health of the elderly is very important being recognized. Provide basic data for improving the quality of life for the elderly, to determine whether the oral health of the elderly whether oral self-perception of health and any related wish. Methods: Surveys to May 20 from April 15, 2011, subjects were elderly and living in Daejeon and Chungnam 277 people were examined. All the statistics using SPSS 18.0 for the determination of statistical significance, and the significance level was 0.05. Results: 1. Recognized, the most common oral health, self-aware bad the state (46.2%) there was no significant difference in the general characteristics according to self-Oral health status, remaining natural dimensions or the intra-oral prosthetic, there was no significant difference. More teeth, residual phase, in accordance with intra-oral prosthetic mandibular Not all dentures, partial dentures, full dentures net self-perception of oral health status better recognized. 2. According to the type of partial dentures, oral health status self-phase, mixed mandibular removable, fixed, fixed, removable partial dentures in order to recognize that good oral health, self-aware state, showed between them, there was no significant difference. 3. Of variable dimension that has nothing to do with the remaining natural maxillary and mandibular prosthetic maxillary prosthetic mandibular partial dentures, age income, a positive correlation was negatively correlated. The case of the mandible, the mandibular prosthetic mandibular partial denture, maxillary prosthetic, the amount of income were correlated. 4. Intra-oral Prosthetics correlation variables in the maxillary, mandibular prosthesis, the positive correlation between income, age was negatively correlated, if the income of the mandible. Maxillary partial denture has nothing to do with the variable portion of the mandibular denture, age was a negative correlation was found. Conclusion: Satisfaction and how now it is important simply to live as long, but you need to pay attention to the quality of life, sometimes with an aging population and the increase of soybean To buy the loss of teeth causes the typical health problems of the elderly. Elderly people of any relevant oral health and the oral cavity by the state to determine whether to provide the basic data for oral health education was more residual value, intra-oral prosthetics there is no more self-aware, the oral health status is good to recognize that appeared. Strengthen the oral health education to improve the quality of life of the elderly, and is thought to be necessary to increase the number of residual.

Background: The population of Gangneung City in South Korea has shown a gradual increase in the proportion of individuals aged 65 years and older, and the most frequently reported diseases for several years have consistently been periodontal diseases, including gingivitis and periodontitis. The regional imbalance in the distribution of dental personnel and resources has emerged as a problem of inequality in the use of dental care. It has been advocated to identify areas with disadvantages in dental care and develop public dental policies based on that. This study aimed to develop a customized oral healthcare program for local seniors based on a Public-Private-Academic Partnership, and to evaluate the oral health status of older adults in Gangneung City. Methods: The participants were residents aged 60 years and above in Gangneung City. A questionnaire including general information, systemic health status, and oral health status was administered to the participants. In addition, oral healthcare and education tailored to each individual's health status were provided once or twice based on their oral health status. The collected data were analyzed using IBM SPSS Statistics 25 for descriptive statistical analysis. Results: Among the older adults in Gangneung City, 75% had at least one prosthesis and exhibited symptoms of gingivitis or periodontitis. Additionally, the modified sulcus bleeding index decreased among participants who underwent the program twice. Over 90% of the participants expressed satisfaction with the program. Conclusion: The program appeared to contribute positively to the oral health promotion among local seniors. Further oral healthcare programs should focus on seniors in rural and old urban areas to reduce disparities in oral health across regions.

The purpose of this study was to observe histopathologically the influence of advanced periodontitis on pulp tissue, and to conclude the correlation between the results with clinical manifestations. The samples were teeth with over 7mm pocket depth and over 50% radiographic bone loss. These were diagnosed to have very poor prognosis and thus planned to be extracted. Those with any of following conditions were excluded from the samples, loss of vitality, periapical pathology, restoration or prosthesis, dental caries, and attrition or abrasion. It was because these conditions could affect pulp without any correlation with periodontal disease. For the experiment, 17 teeth from 11 patients were selected. Average age of patient was 47. Each tooth was examined for following categoris; pocket depth, gingival recession, electric pulp test, mobility, percussion test, sensitivity test. The extracted teeth were fixed buffered neutral formalin solution. It was decalcified using 4% nitric acid. Sliced histological samples observed using light microscope, for pulp status, and severeity of inflammation. 4 samples were excluded due to histologic sample discrepency. Thus 13 samples were subject to observation. 4 showed normal conditions. Focal reversable pulpitis was shown in 5 samples. Chronic pulpitis was observed 1 sample. Pulpal abscess was observed in 3 samples.

From September 1989 to March 1996, 13 patients with prosthetic valve thrombosis underwent reoperdtion on 16 occasions. The mean interval between implantation and reoperation was 27.8 months. The anticoagulation status was inadequate in 44% of th Instances. The majority(75%) were in NYHA functional class IV, 6 of them being in shock. Reoperation was performed for valve replacement(15 of 16 occasions) or thrombectomy(1 of 16 occasions) within 3 to 192 hours(mean 33.5 hours). Operative mortality at reoperation was 25%(4 patients). Re-thrombosis occurred In 3 patients. Long-term outcome was satisfactory in all survivors with a mean follow-up of 30.B months. The present results indicate that an early diagnosis and prompt surgical intervention is needed to decrease operative mortality.
