The purpose of this study was to develop an inclusive dental hygiene practice model in an effort to stir up the self-directed learning of learners to boost their problem-solving skills and ability of providing inclusive personal oral health care in a systematic and efficient manner. The subjects in this study were 41 dental hygiene students who were in their second year in C college located in South Jeolla Province as of 2009. An inclusive dental hygiene practice was implemented during a 15-week period of time from August 31 to December 7, 2009, and a self-administered survey was conducted before and after that by using the same questionnaires. Whether there were any differences between before and after the application of the inclusive dental hygiene practice model was checked, and there was improvement in all the learning motivation, self-directed learning capabilities and satisfaction level. Concerning the relationship of academic standing to changes in learning motivation, self-directed learning capabilities and satisfaction level, the inclusive dental hygiene practice model brought more favorable changes to the students in the lower tiers. The inclusive dental hygiene model should be applied to not only practical courses but theoretical ones so that learners could make progress both in theory and practice, and evaluation tools geared toward assessing their academic achievement and practical abilities should be developed.

The purpose of this study is to determine critical assessments and core competencies, and to determine the competence and discipline of self-assessment. We surveyed 511 students who graduated from 12 universities. Self-efficacy 24 items were measured on a 5-point scale, 8 core competencies and 52 detailed competencies were self - assessed from 0 to a maximum of 10 points. The higher the score, the higher the self - evaluation competency level. Statistical analysis was performed using SPSS 20.0 Ver., And a statistical significance level of 0.05 was considered. The self - evaluation competency level was the highest at 6.7 points in the clinical dentistry area, and the lowest at the evidence - based decision area of 5.7 points. Self-regulation was found to be positively related to the self-evaluation core competence level among self-efficacy sub-factors. As the students' self-efficacy affects subjective academic achievement and self-evaluation, it is necessary to develop and apply relevant programs to enhance critical thinking in curriculum, apply problem-based learning method, improve self-efficacy and leadership, It should be possible to cultivate.

An orally disintegrating film (ODF) based on hyaluronic acid (HA) containing vitamin D was developed. The vitamin D content in the ODF was set based on the adequate intake (AI) of vitamin D from 0 to 10 AI (0, 1, 4, 7, and 10AI). The control (0AI) had the highest thickness and showed the longest disintegration time among the samples. The moisture content of the ODFs was significantly lower in those with vitamin D compared to the control. As the amount of vitamin D increased, the water vapor permeability (WVP) of the ODFs decreased, and the opacity significantly increased. The tensile strength was higher in the films containing vitamin D compared to the control films. However, the elongation at the break showed no significant difference among the films. The vitamin D content in the film was reduced by 25.7-44.2% during processing compared to the amount that was originally added. Based on the above results, a new and convenient vitamin D delivery system, an ODF, could be successfully produced.

This study aims to present a fundamental data base to figure out the mental and the physical conditions that the dental technicians are facing and ultimately to develop a health care program to deal with their health related problems. To this end, we took an analysis on the health status among the subjects of 895 dental technicians currently working at the dental lab around the nation from January 15 to March 31, 2009 by way or Todai Health Index(THI). Of the average scale point in accordance with 12 scale scores of the physical and the mental subjective symptom, the results revealed that the physical appeals (21.10) were higher than the mental appeals (18.49) and the multiple subjective symptom was marked as 38.44 followed by the mental irritability (25.92). In gender differences, the females proved to be higher than the males in both physical appeals and mental appeals while the physical appeals were dominant in both genders. The physical appeals were higher than the mental appeals with regard to the general characteristics. In the case or the group or age twenties as shown in the physical and mental average scale point, the other groups showed 21.55% of the physical appeals among the married whereas the mental appeals showed the highest point as 18.70 in the unmarried group. In job position, the other groups marked the highest, in working condition, below average group marked the highest, in frequency of break time, none group marked the highest. We drew a conclusion form this study that the dental technicians gained the higher points in the item or the multiple subjective symptom, the menial irritability, and the irregular life. More research on th is phenomena should be followed along with the development of various and practical health care programs to promote the health or dental technicians.

It is so hard to obtain optimal anterior esthetics in the implant prosthesis. This is not only because of hard and soft tissue problem such as alveolar bone resorption and interdental papilla loss but also because of prosthetic limitation related to marginal exposure of metal abutment and metal ceramics and low transillumination. In this case, guided soft tissue healing is obtained using a long term provisional restoration with soft and hard tissue augmentation or immediate implantation. Then, this healed tissue is transferred to final master model using a customized impression coping and the implant is restored with a customized zirconia abutment and a all ceramics. This case presents satisfying result esthetically and functionally.

오늘날 스트레스라는 단어는 모든 현대인과 방송, 언론매체에서도 매일 거론되어질 정도로그 중요성이 대두되고 있다. 의학계에서도 스트레스를 단순한 심리적 문제로 국한시키지 않고 과도한 스트레스가 지속될 경우 신경계와 내분비계, 면역계의 변화를 초래해 인체의 항상성에 영향을 미쳐 질병을 일으킨다는 것을 인식하고 있으며 이에 대한 연구가 진행되고 있다. 이러한 질병의 발생과정에서 생체의 일부조직이 파괴됨으로써 기능과 형태변화가 초래될 때 apoptosis가 관여하고 있으며 이에 본 저자는 스트레스와 구강악안면영역에서 발생할 수 있는 질병과의 상관관계를 규명하기 위해 이종의 한냉 스트레스와 다소의 굴신을 허용한 중등도의 구속 스트레스를 부여한 후 측두하악관절 활막의 변화를 전자현미경관찰을 통해 밝혀내고자 한다. Sprague-Dawley계 웅성 백서(200-230 g/bw) 33마리를 구속스트레스부여군 (12마리), 한냉스트레스부여군 (12마리) 및 정상군 (3마리)으로 나누고 이들을 각각 구속장치에 구속한 후 1, 3, 5, 7일에 각각 희생시켰으며 측두하악관절 활막의 변화를 전자현미경으로 관찰하였다. 그 결과는 다음과 같다. 1. 중등도의 구속스트레스군에서 사립체는 부분적으로 농축된 소견을 보였으며 수와 크기에 있어 시간이 지남에 따라 점차 감소하는 소견을 보였다. 2. 중등도의 구속스트레스군에서 과립내형질망은 점점 확장되었으며 불규칙한 형태를 나타내었다. 3. 중등도의 구속스트레스군에서 물결모양의 핵막의 이중구조가 7일군에서 관찰되었다. 4. 한냉 스트레스군에서 사립체는 1일, 3일군에서 약간 부푼 형태를 가지고 그 수가 다소 감소되었으나 시간이 지남에 따라 5일, 7일군에서 건강한 모양으로 점차 증가되었다. 5. 한냉 스트레스군에서 과립내형질망은 1일, 3일군에서 불규칙하게 확장된 소견을 보였으나 5일, 7일군에서는 잘 발달된 형태로 핵 주위에서 다수 관찰되었다. 6. 한냉 스트레스군에서 핵은 전 기간에 걸쳐 큰 변화를 보이지 않았다. 이와 같은 결과를 토대로 측두하악관절 활막조직은 한냉 스트레스 및 중등도의 구속 스트레스에 대하여 중등도의 저항성을 가지고 있는 것으로 생각되며 생리적 적응한계를 넘는 과도하고 지속적인 스트레스에 의하여 활막조직이 apoptosis되어 측두하악관절에 병리적 변화를 초래할 가능성이 있다고 사료되어 이후 지속적인 연구가 요구된다.

The Ministry of Health and Welfare in Korea has enforced the oral health promotion program for elderly in Korea. There are the denture delivery program and the fluoride application-scaling program for elderly. Donggu Public Health Center in Daejeon has delivered the fluoride application-scaling program for elderly since the demonstration project in 2009. The official dental hygienists had a prior consultation with Dong-gu branch of Korean Senior Citizens Association in Daejeon. We expanded the program through government office, welfare centers, and nursing homes. The participants were satisfied with the public relations (95.2%), scaling (99.7%), fluoride application (91.5%), toothbrushing education (98.6%), and denture cleaning education (96.6%). After a medial accident with persistent bleeding, the pre-inspection survey about systemic disease and medication was reinforced. The official dental hygienists have agonized over the low participation of the low-income group and the overlap benefit with health insurance benefit of scaling. We suggested it be needed the assessment of the public oral health program to overlap with health insurance benefit.

The purpose of this study was to analyze the reasons and mean age for tooth extraction among patients living in Busan city. The researcher observed 1,119 patients' teeth extracted due to dental caries, periodontal disease and other reasons. This study examined the reasons for tooth extraction by age, sex, and tooth-kind. The reasons for tooth extraction were dental caries, periodontal disease, eruption problems and others. The obtained results were as follows; 1. Among the reasons for tooth extraction, dental caries accounted for 25.9%, periodontal disease 56.5%. 2. Periodontal disease was the main reason for tooth extraction and continued throughout life irrespective of sex. However dental caries was remarkably increasing in those aged 30 years old and under. 3. In the extraction of permanent teeth, males outnumbered females while upper teeth did lower teeth. 4. Although the third molars were most extracted in all kinds of teeth, the main reasons for the extraction were eruption problem. 5. The mean age of the tooth extracted was 47.9 years in both sexes for the mandibular first molars and the mandibular first molars had the shortest life except third molars of total teeth. The mandibular canines had the longest life of total teeth. Because dental caries and periodontal disease are the main causes of tooth extraction in Korea, the dental health policy should be focused on the prevention and treatment of these two diseases in the government level.
