The purpose of this to inquire of the people who run a dental mechanical laboratory having troubles to manage and to find out the reform measures on the point at issue. With having done random sampling for the chiefs of dental mechanical labs across the nation, and then marking the analysis of the data for the survey, I came to a conclusion to be as follow. 1. The operating problems in dental mechanical laboratory in Korea is that it is too near at hand that the requested days for the manufacture of dental prosthesis appliances form dental clinics(45%)(P<0.01) 2. The problem of dental mechanic manpower was due to a small salary and inferior working environment(35% each)(P<0.01) 3. Some of them discount dental mechanical charges in manufacturing dental prosthesis appliances(36.7%)(P<0.01) 4. Many of them employed unlicensed dental technicians(61.7%)(P<0.01) As a counterplan for the aforementioned, I think that the whole dental mechanics should cooperate in breaking off the customary custom to allow a discount on the dental mechanical charges and readjust the dental mechanical charge to a realistic level so as to contribute to the development of the dental mechanical community and the vetterment of the public oral hygience.

Purpose: As the demand and importance of aesthetic aspects in dental treatment become higher, much attention is paid to materials used for dental prostheses. Thus, the marginal fidelity of most-commonly used alloy, IPS - Empress and ZrO2 ceramic is compared. Methods: The alloy core made by casting, IPS - Empress core made by pressing and ZrO2 ceramic core made by CAD/CAM are used to make 10 samples respectively. For each core, three points were measures and the optical microscope (Axio Imager.Alm,Zeiss co., Oberkochen, Germany) was used to observe the cores with a magnification of 100. Results: As for alloy, IPS - Empress and ZrO2 ceramic, the average and deviation of their marginal distance are $29.91\;{\pm}11.93{\mu}m$ for alloy, $33.45\;{\pm}8.61{\mu}m$ for IPS - Empress, and $31.55\;{\pm}9.85{\mu}m$ for ZrO2. The one-way ANOVA test was conducted to compare them. However, there was no statistically significant difference among them. Conclusion: The study on marginal fidelity of alloy, IPS - Empress, and ZrO2 ceramic shows they have no marginal fidelity problem clinically. Therefore, if a system is selected based on the patient's condition or treatment method, there will be no problem.

Objectives: The purpose of this study is to provide a reference material for improving the work environment to reduce the turnover intention of clinical dental hygienists in the future by identifying the problem of the turnover phenomenon of clinical dental hygienists in Seoul and Gyeonggi-do. Methods: The method of this study used the raw data of 'A Survey on the Current Work Environment of Clinical Dental Hygienists' from August 29 to September 28, 2017, and 2,974 clinical dental hygienists in Seoul and Gyeonggi-do were finally selected as the study subjects. Results: The results showed that excessive workload, inadequate pay, and hierarchical organizational culture of a workplace were the main factors influencing the turnover intention of clinical dental hygienists, and the lack of welfare system, low wage and practical experience also affected their turnover intention. Conclusions: In order to reduce the turnover intention of clinical dental hygienists, it is important to create a working atmosphere where the members of an organization can freely share and communicate suggestions and improvements, and to pay their salary appropriate to the duties and roles of dental hygienists, and accordingly they will be able to carry out the duties with responsibility for a long time without moving to another organization.

purpose : The purpose of the study is to investigate opinion on the legalization of the actual work of clinical dental hygienists. Methods : A self-reported questionnaire was completed by 171 dental hygienists in Busan and Gyeongnam from December 1, 2017 to January 31, 2018. Structured questionnaires were uesd for analysis. The collected data was analyzed using IBM SPSS. Statistic 20.0. Results : The first, assist of dental treatment, Second, dental health care education and consulting duties, and third priority preventive duties were found to be the most important duties in the dental office. Currently, it was investigated perform in a lot of workplace. Preventive treatment tasks include scaling, teeth polishing, applying fluoride and assist of dental treatment include preparation for medical care, preparation for implant surgery, preparation for oral surgery, implant surgery assistant and patient care training, and preparation for periodontal surgery. Conclusion : As a result, the dental hygienist performing a lot of dental assist tasks, oral health education counseling and preventive duties. Nonetheless, clinical dental hygienists are outlaws due to the disparity between practical and legal duties. Therefore, it is urgent to legislate actual duties of dental hygienist so that experts can fully exercise the competency of the public in promoting dental health. Relevant governments and related organizations should take reasonable measures to solve this problem.

This study aimed to investigate the relationship between the experience of incivility in clinical practice and stress coping strategies among students enrolled in the Department of Dental Hygiene with clinical practice experience. The study randomly sampled subjects from a group of 150 dental hygiene students attending the Chungcheong area. Descriptive statistics, t-test, ANOVA, and Pearson's correlation analysis were conducted. The trainees experienced a level of incivility of 1.69, and their level of coping with the resulting stress was 2.58. The study found significant results in terms of gender, clinical practice, and major satisfaction when examining the incivility experienced by trainees based on general characteristics. Among these general characteristics, there were statistically significant differences in the avoidance focus among the sub-domains depending on the grade, number of practicums, and satisfaction with clinical practice. Additionally, the problem-solving focus showed significant results depending on satisfaction with the major. The incivility experienced by trainees showed a positive correlation with avoidance-oriented coping among stress coping strategies (r=.268), social support-seeking coping (r=-.045), and problem-solving-oriented coping (r=-.034) was found to have a negative correlation. If you find yourself in a situation where you encounter incivility, it is believed that developing communication skills and assertiveness training can help you respond more actively instead of passively, which is an avoidance-oriented approach. In addition, it is important to consider that schools and training organizations should collaborate to establish an official reporting system to ensure that any instances of incivility experienced by trainees are not ignored.

Tooth loss is very a very common problem; therefore, the use of dental implants is also a common practice. Although research on dental implant designs, materials and techniques has increased in the past few years and is expected to expand in the future, there is still a lot of work involved in the use of better biomaterials, implant design, surface modification and functionalization of surfaces to improve the long-term outcomes of the treatment. This paper provides a brief history and evolution of dental implants. It also describes the types of implants that have been developed, and the parameters that are presently used in the design of dental implants. Finally, it describes the trends that are employed to improve dental implant surfaces, and current technologies used for the analysis and design of the implants.
