This study was peformed in order to find out the relationship between the causing factors and the production of each gas 01 oral malodor, to contribute the oral malodor control at dental clinic as well as to establish the effective application of malodor control project for public oral health program 127 patients from 20 to 40 years old who had been visited for preventive dental cares were participated for the study. Such items as caries status, periodontal status, salivary flow, viscosity, pH. Snyder test, plaque deposit and tongue plaque were checked through the oral examination in order to find out the contributing factors Hydrogen sulfide, Methyl mercaptan, Di-methyl sulfide and Ammonia gas components were checked with Oral-Chroma and Attain, the oral malodor check units. Not only the corelation coefficiencies but also the multi-way variance analysis were calculated between each causing factor and each component of oral malodor gases to estimate the contributing factors of the oral malodor. 1. There was no relationship between the caries status and each component pf the oral malodor such as sulfur compound or Ammonia, both in laboratory test and VAS test (pF0.05). It revealed negative relationship between Hydrogen sulfide and FT(rM-0.1904. pE0.05) as well as the VAS and FT (rM-0.210. pE0.05). S0, it was estimated that the less oral malador was recognized when caries state changed to filled state in Hydrogen sulfide laboratory test or VAS test 2. High relationship was showed between salivary flow and Hydrogen sulfide (rM-0.183, pM0.039), Methyl mercaptan(rM-0.234, p-0.008). Dimethyl sulfide(rM-0.234, pM0.008) and Ammonia(-0.361. pM0.001) gas(pE0.05). 3. There was a high relationship between M-PHP(Modified-Patient Hygiene Performance Index) and tong plaque all kinds of sulfide(rM0.249. pM0.005). Ammonia gas component(rM0.232, pM0.009). 4. It was found that considerable relationship was appeared between the periodontal status and Ammonia gas (rM0.274, pM0.002), so, it should be needed to control Ammonia. Such dental Cares as the prevention or early treatment of periodontal disease and the accelerating the salivary flow as well as reducing the amounts and activities of filament or spiral typed oral micro-organism were recommended for adults, not only for dental care program at the dental clinics but also for public health programs, in order to promote the oral health and quality of file for individual and community peoples.

Federal disability law has evolved from several laws geared to protect people with disabilities since the late 1960s and early 1970s. When U.S. Congress passed the Americans with Disabilities Act (ADA) in 1990, no federal statute prohibited the majority of employers, program administrators, owners and managers of places of public accommodation and others from discriminating against people with disabilities. Toward the ends to assure equality of opportunity, full participation, independent living, and economic self-sufficiency for individuals with the disabilities, the ADA pursues three major strategies: Title I addresses inequality in employment, Title II, inequality in public services, and Title III, inequality in services and accommodations offered by private entities. The purposes of the study were to analyze the impact of the ADA on health care for persons with disabilities and to review the ongoing health policy reforms at the federal and state governments. Essential remedies that the ADA contemplates are based on two principles, simple discrimination and reasonable accommodation, which significantly improved access to quality care, especially long-term care, by persons with disabilities. However, the ongoing Medicaid policy reforms to control rising health care costs in the U.S. could threaten the access to care by persons with disabilities in optional groups and to optional care services by persons with disabilities in mandatory groups.

Objectives : The purpose of this study was to examine the factors related to the dental caries and periodontal diseases of Korean elderly people in terms of demographic characteristics, oral health promotion behavior and systemic diseases in an effort to provide information on national policy setting and policy evaluation about the prevention of tooth loss resulting from severe oral diseases and the promotion of elderly people's oral health. Methods : The first-, second- and third-year raw data of the 4th National Health and Nutrition Survey were utilized, and the data of 3,882 elderly people who got a dental checkup were analyzed. The statistical package SPSS WIN 19.0 was employed to make a logistic regression analysis. Results : The senior citizens who did toothbrushing less frequently were more likely to have dental caries. As for periodontal diseases, the men were 1.34-fold more likely to have periodontal diseases than the women, and the respondents whose self-rated health state was worse were 1.40-fold more likely to have periodontal diseases than the others whose self-rated health state was better. The senior citizens who ever received treatment from unqualified people were 1.30-fold more likely to have peridontal diseases, and those who took neither vitamin compound nor minerals were 1.30-fold more likely to have periodontal diseases. Those who suffered from low High-density Lipoprotein cholesterol(HDL) were 1.35-fold more likely to have periodontal diseases than the others who didn't. Conclusions : Those whose self-rated health status is worse should especially be concerned about periodontal diseases. Specifically, it's needed to pay attention to the low-income classes, and the government should take measures to provide quality welfare services for elderly people not to receive treatment from unqualified people. Besides, research efforts should be made to determine the relationship between periodontal diseases and low HDL-cholesterolemia.

The purpose of this study is to provide a guide for selection of oral hygiene devices for nations and establishing valid indication of recently popularized water jet. The author has divided 36 persons into general, orthodontic, periodontal patients according to their oral hygiene state, and then evaluated the degree or decrease in plaque indices and gingival bleeding indices. The obtained results were as follows. 1. When both manual toothbrush and water jet were used together by three kind of patients, significant decreases in plaque index were observed in all patients, after 4 weeks compared with ordinary toothbrushing only(p<0.05). 2. When both oral hygiene devices were used together by three kind of patients, significant decreases in gingival bleeding index were observed in all patients after 4 weeks compared with ordinary toothbrushing only(p<0.05). 3. Singificant differences of the average gingival bleeding index & plaque index among three kind of patients were observed(p<0.05). 4. Therefore, it is concluded that for effective oral hygiene care. water jet can be recommendable to general patients, especially to orthodontic or periodontal patients.

The aim of this study was to investigate the relationship between the oral health status of elderly under visiting health care and their oral health-related quality of life. The subjects were 300 elderly under visiting health care program over 65 years old in Asan city and they were interviewed. The result showed that average Geriatric Oral Health Assessment Index (GOHAI) score was 37.36 and the lowest scored question was 'never satisfied with the oral condition'. In GOHAI related to oral health behaviors, unmet dental treatment experience was statistically significant (p<0.001). In overall GOHAI, number of remaining teeth (p<0.001) and the age had statistical significance and men had higher score in pain and discomfort (p<0.05), under age of 74 limited function factors score was high (p<0.01). The number of remaining teeth had statistical significances in most factors except pain and discomfort (p<0.001). The factors affecting GOHAI were age (p<0.05), number of remaining teeth (p<0.001) and perceived health state (p<0.001). In order to improve oral health-related quality of life of elderly receiving visiting oral health care services, it is necessary to increase denture support by securing budgets and developing oral health promotion programs at the local government level.

Three-dimensional (3D) computed tomography image models are helpful in reproducing the maxillofacial area; however, they do not necessarily provide an accurate representation of dental occlusion and the state of the teeth. Recent efforts have focused on improvement of dental imaging by replacement of computed tomography with other detailed digital images. Unfortunately, despite the advantages of medical simulation software in dentofacial analysis, diagnosis, and surgical simulation, it lacks adequate registration tools. Following up on our previous report on orthognathic simulation surgery using computer-aided design/computer-aided manufacturing (CAD/CAM) software, we recently used the registration functions of a CAD/CAM platform in conjunction with surgical simulation software. Therefore, we would like to introduce a new technique, which involves use of the registration functions of CAD/CAM software followed by transfer of the images into medical simulation software. This technique may be applicable when using various registration function tools from different software platforms.

Preoperative surgical simulation in orthognathic surgery has progressed in recent years; the movement of the mandible can be anticipated through three-dimensional (3D) simulation surgery before the actual procedure. In this case report, the mandible was moved to the intended postoperative occlusion through preoperative surgical 3D simulation. Right-side condylar movement change was very slight in the surgical simulation, suggesting the possibility of mandibular surgery that included only left-side ramal osteotomy. This case report describes a patient with a mild asymmetric facial profile in which the mandibular menton had been deviated to the right and the lips canted down to the left. Before surgery, three-dimensional surgical simulation was used to evaluate and confirm a position for the condyle as well as the symmetrical postoperative state of the face. Facial asymmetry was resolved with minimal surgical treatment through unilateral intraoral vertical ramus osteotomy on the left side of the mandible. It would be a valuable complement for the reduction of the surgical treatment if one could decide with good predictability when an isolated intraoral vertical ramus osteotomy can be done without a compensatory osteotomy on the contralateral side.

The purpose of this study was to compare and analyze the behavior status of oral health between dental hygiene and non-dental hygiene students. The subjects in this study were students from two different colleges that were respectively located in Seoul and Gwangju. In order to examine the necessity of oral-health education, the self-recorded questionnaires had been widely distributed and surveyed from June 2006 to May 2007. The following results were obtained on the basis of comparative analysis through the collected materials. 1. As a result of surveying the actual condition of managing oral health, regarding the frequency of tooth brush, the dental hygiene students were the largest in 3 times. And, the non-dental hygiene students were indicated to be the largest in two times(p < 0.01). 2. As for the experience of scaling, the dental hygiene students were the most in having experience(50.9%), and the non-dental hygiene students were the most in having no experience(56.8%)(p < 0.001). 3. As a result of examining about the experience of oral-health education, the dental hygiene students were many in a case of having experience. And, the non-dental hygiene students were many in a case of having no experience(p < 0.001). The findings of the study showed that in terms of the state of oral health care, the dental hygiene students who received a lot of oral health education excelled the other students who didn't.

The study aims to determine the status of oral health of mental illness patients and establish the preliminary data. The examinations and questionnaire survey were done 92 psychiatric patients to measure sociodemographic characteristics, decayed, missing and filled teeth (DMFT) index, patient hygiene performance (PHP) index, community periodontal index of treatment need (CPITN). Result of the missing teeth index in the state of oral health was higher in the hospital group (6.42) while the filled teeth index was higher in the center group (4.78). In the DMFT index, mental illness patients were higher than the national sample. The oral health status of medical aid recipients was poorer as the subjects were older and less educated (p<0.05). The PHP index was 3.41, close to the bad oral hygiene state. The hospital group (81.7%) required higher need for periodontal treatment. The periodontal health state was much poorer especially when the subject was in the age of 40's and 60's, received less education, and had no family (p<0.05). $CPITN_3$ was higher in the hospital group (13.3%) than the national sample (5.7%). The mental illness patients were socially vulnerable, therefore oral health care program should be needed and age, education level, health insurance type, presence of family and other factors needs to be considered in this approach.

The purpose of this study was to examine the oral health behavior and awareness of teachers in community children's centers, the state of oral health care among children in the centers and the opinions of the teachers on child oral health education in a bid to gather information required for the development of oral health education programs geared toward community children's center teachers. The subjects in this study were 178 teachers who worked in 98 community children's centers in the city of Incheon. After a survey was conducted from April 28 to June 4, 2010, the collected data were analyzed. The findings of the study were as follows: The 57.3% of the teachers investigated provided toothbrushing guidance from time to time or couldn't do it at all. As for the reason why toothbrushing guidance was scarcely conducted, the largest group cited shortage of sinks(27.5%) as the reason, and the second biggest group replied they couldn't afford to pay attention to that due to heavy workload(20.6%). The third greatest group was pressed for time(16.7%). The teachers got a mean of 3.27 in oral health behavior, and 87.7% were concerned about children's oral health. The group of teachers who ever received oral health education was significantly better at oral health behavior and showed significant more interest in oral health(p<0.01). The 97.2% of the respondents considered oral health important. Concerning the reason, they replied it was crucial for systemic health (74.2%). The 89.4% of the teachers viewed child oral health education as necessary, and 86.5% had an intention to provide oral health education for children. They hoped to receive education on the oral health control act(4.52) and the prevention of dental caries(4.40). The above-mentioned findings confirmed that in order to step up the oral health promotion of child users of local children's centers, it's necessary to provide secondhand education for them through their teachers who have a great impact on them. Therefore the development of oral health education programs that cater to local children's center teachers is required.
