In the field of dentistry, there existed relatively few emergency patients or patients who need intensive care and thus had low medical dispute rates. However, these days, there is a general tendency of increased medical disputes. Although many medical disputes are caused by medical accidents of the dentists, because dental assistants are also lawfully involved in practicing dentistry, there is a possibility of medical disputes or medical accidents caused by dental assistants. Therefore, the role of the dental assistants cannot be ignored. This study consists of a survey given to dental hygienists currently working in general hospitals, dental hospitals and private dental clinics. Following is the results of the analysis of 275 respondents' backgrounds, medical disputes rates including patients' complaints, their understanding of medical regulations and their general understanding of overall dental practice and medical disputes. 1. 251 of 274(91.6%) respondents doubted the risk of medical accident and dispute. 2. 81(29.5%) dental hygienist experienced complaint from patients. They have been working in the private dental clinic, the rate of this experience was high. 3. 349 case of 1805(19.3%) the complaints by patients, highest percentage among its category, were those regarding dental fees and poor service. 4. 129 case of 1805(7.1%) patients' complaints, highest percentage among it's subcategory, were those regarding the absence of explanations of precautions or request of agreements before dental treatment. 5. 252 of 267 (94.4%) dental hygienists chart after a scaling treatment. However, only 55(20.7%) dental hygienists chart the fact of explaining the precautions. 6. 6(2.2%) dental hygienists do not inspect patients' medical history, if patients don't mention it. 7. 104 of 274(38.0%) dental hygienists responded to be capable of administering first aid treatment. 8. 115(41.8%) dental hygienists have a first aid kit and equipment. 9. In case of medical dispute, 268(97.8%) dental hygienists respond that, charting plays a big role in resolving the dispute. 10. In case of medical dispute, 272(93.3%) dental hygienists respond that, explanation and agreement before treatment have an important role in settlement of dispute 11. Only 160(58.4%) dental hygienists responded correct answer that the duration of keeping medical records is 10 years. 12. 124(45.3%) respondents thought that it is legal for a dental hygienist to take a panoramic dental X-ray, 71(25.9%) respondents thought that it is legal practice cervical resin treatment by dental hygienist, and 37(13.5%) respondents thought that it is legal extract primary teeth by dental hygienist. 13. 24(18.76%) respondents thought that it doesn't matter to tell patient's state to others 14. 272(99.27%) responded that receiving education for the prevention of medical disputes was needed and of them, 61.0% thought it was urgent. 15. 186(64.2%) has never had classes regarding the prevention of medical disputes while in school and 212(77.4%) has not had the same type of classes after graduating from school. 16. 256(93.4%) responded that there will be even more of an increased number of medical disputes. Among them, 83.3% of respondents though that due to the increased opportunity of acquiring information through the internet and mass media. The study shows that 29.5 percentage of dental hygienists have experienced the medical disputes and complaints and they are lack of recognition of medical regulations and dental hygienist's official duty. So, there is a big potential of the percentage to increase. Therefore, the correct understanding of explaining precautions and requesting agreement before dental treatments and performing them are mandatory. Moreover, classes regarding the prevention and counterplans of medical disputes need to be widely offered.

Objectives : In this study, the dental treatment satisfaction degree of the patients, who experienced the sleep dental treatment or non-sleep dental treatment, the revisit rate and the differences among the encouraging intention were compared and analyzed, and the primary factors through which the satisfaction degree of sleep dental treatment has influence on the revisits and the encouraging intention were analyzed, and the proposal was made on clinic management to raise qualitative medical service level on the basis of this study. Methods : The questionnaires filled out by the 202 users of a certain dental clinic located in Pohang-si, Gyeongbuk were analyzed. The frequency analysis and the crosstabulation analysis of the general characteristics of survey participants were carried out, and the satisfaction difference between the sleep dental treatment and the non-sleep dental treatment was identified with the t-test analysis. The multiple regression analysis were carried out to identify the factors through which the sleep dental treatment has influence on the through which the satisfaction degree of sleep dental treatment has influence on the satisfaction degree of the medical service and the revisited dentists. Results : In the medical service satisfaction degree in general, the sleep dental treatment had the higher meaningful value than the non-sleep dental treatment(p<0.05). In the case of the difference in satisfaction degree on each medical service factor, the satisfaction of the sleep treatment group was high in every case, but the meaningful difference showed up in the factors of waiting time, treatment procedure, revisit and the encouraging intention(p<0.01). The revisit to the sleep treatment dental clinic and the recommending dentist increased in proportion to the satisfaction degree of sleep dental treatment, and the Beta value appeared to be 0.337 at the influence of the subordinate variable(p<0.001). As for the influence on the sleep dental treatment satisfaction, the Beta value of the dental hygienist was the highest, marking the value at 0.375(p<0.01). As for the satisfaction of the patients who experienced the sleep dental treatment, the Beta value of the treatment fee was the highest, marking 0.352(p<0.001), in the multiple regression analysis of the revisit and the encouraging intention, and the 0.156 of dentist factor and the 0.152 of treatment procedure and waiting time showed lower regression coefficient(p<0.05). Conclusions : It is assumed that the satisfaction degree of sleep dental treatment, which is carried out as a new dental service has influence on the increase of revisit to the dental clinic as an important factor. But it was disclosed that the high level of treatment fee has the biggest influence on choice of revisit to the dental clinic. In the current medical charge system, the sleep dental treatment appeared to have a big influence on raising the quality of dentists, the satisfaction of patients, the revisit and encouraging intention, and also the roles of the dental hygienist was important. It is assumed that these facts are functioning as the factors that are linked to the increase of revisit and the encouraging intention.

Aesthetics can be affected by the interest and the trend of the time. There are the limits of the equipment and materials required for the times, aesthetic case is also considered necessary to overcome them and will introduce the following case in accordance with the patients demands and circumstances. I hope the further development of CAD/CAM by taking over the things have done in the analogue by utilizing the latest technology that is thought to challenge the current limit itself is important. Digital has the advantages in various perspectives. Especially, I am very interested in as related to "digital communication." In particular, when utilizing the data using intra oral scanner can easily direct converse about prosthesis between the dentist and the dental technician through a software program Now, as the digital communication affects the integrity of the prosthesis directly, I had a expectation of a new era for the prosthetic and aesthetics. In this case report, I would like to introduce direct and real digital communication through the following 2 parts.

To investigate the necessity of periodontal treatments, and the association of the health lifestyle with periodontal treatments, the data of 11,488 adults targeted in the 5th (2010, 2012) National Health and Nutrition Examination Survey were used in this study. Chi-squared test was conducted to compare the subjects' general features with the health lifestyle of the patients who needed periodontal treatments. Logistic regression analyses were conducted to confirm the variables that could affect the necessity of periodontal treatments. As a result of verifying the necessity of periodontal treatments according to the general features and health lifestyle, the necessity decreased with the higher income level and education level, and in the cases of nonsmokers, frequent toothbrushing, and using oral hygiene products. When the subjects who did not had oral examinations, their necessity for periodontal treatments significantly increased (p<0.01). The variables that affected the necessity of periodontal treatments included residence, gender, education level, obesity, and oral examinations (p<0.01). Therefore, health lifestyle was thought an important variable that had affected the oral health status. Professional dental hygienists must provide people with action programs of health lifestyle to promote the national oral health status.

브로네마르크가 골유착성 임플랜트를 소개한 이래로, 현재 골유착성 임플랜트에 의한 치료는 안전하고 안정적인 방법으로 여겨지고 있다. 골유착성 임플랜트를 이용한 초기의 치료는 무치악 환자의 저작기능 회복에 중점을 두어 왔다. 그러나 현재는 환자와 시대의 요구에 따라서 심미성이 주요한 관심사가 되었다. 그래서 표준 지대주보다 더 심미적인 지대주 시스템들이 개발되었다. 다양한 직경의 임플랜트 고정체에 관한 임상가들의 요구에 의해 직경 이 큰 고정체가 생산되기 시작했으며, 5mm의 직경을 갖는 고정체가 그 예이다. 골유착성 임플랜트를 사용하여 보철치료를 할 때, 골과 고정체의 계면은 보철물과 지대주에 가해지는 교합력을 인접골에 전달하게 되며, 이것은 계면에 생물학적인 반응을 야기할 수 있다. 임플랜트의 형태는 골흡수와 같은 바람직하지 않은 반응을 일으키지 않도록 고안되어야 하며, 임플랜트 자체가 교합력을 견딜 수 있어야 한다. 그러므로 골유착성 임플랜트 시스템을 임상에 사용하려고 할 때 이것의 생역학적 분석은 반드시 필요하다. 본 연구에서는 삼차원 유한요소분석적 방법을 사용하여 3.75mm직경을 갖는 고정체에 표준 지대주, 이세티콘 지대주, 마이러스콘 지대주를 연결한 모델과 5mm 직경을 갖는 고정체에 표준 지대주를 연결한 모델에 각각 수직하중, 경사하중, 수평하중을 가했을 때의 응력분포를 비교하였다. 본 연구의 결과는 다음과 같다. 1. 모든 모델에서 금나사의 경부, 금원주, 지대주에 응력의 집중이 일어났다. 2. 임플랜트 고정체에서는 고정체 상방 2/3, 그리고 지대주와 접촉하는 고정체 상면에서 응력의 집중이 관찰되었다. 3. 골에서는 상부 피질골에 응력의 집중이 관찰되었으며, 해면골에서는 두드러진 응력의 집중을 보인 부위는 없었으나 고정체의 근단부 주위 해면골에서의 응력값이 비교적 높았다. 4. 5mm 직경의 고정체를 사용하지 않은 모델 중에서, 표준 지대주를 사용한 경우가 가장 응력분산에 유리하였으며 마이러스콘 지대주를 사용한 경우가 가장 불리하였다. 5. 3가지 하중 조건하에서 수평하중과 경사하중의 경우가 수직하중의 경우보다 더 높은 응력값이 관찰되었다. 6. 응력값은 골에서보다 임플랜트 내부에서 훨씬 높았다.
