Purpose: Dual-energy X-ray imaging is widely used today in various areas of medicine and in other applications. However, no similar technique exists for dental applications. In this study, we propose a dual-energy technique for dental diagnoses based on voltage-switching. Materials and Methods: The method presented in this study allowed different groups of materials to be classified based on atomic number, thereby enabling two-dimensional images to be colorized. Computer simulations showed the feasibility of this approach. Using a number of different samples with typical biologic and synthetic dental materials, the technique was applied to radiographs acquired with a commercially available dental X-ray unit. Results: This technique provided a novel visual representation of the intraoral environment in three colors, and is of diagnostic value when compared to state-of-the-art grayscale images, since the oral cavity often contains multiple permanent foreign materials. Conclusion: This work developed a technique for two-dimensional dual-energy imaging in the context of dental applications and showed its feasibility with a commercial dental X-ray unit in simulation and experimental studies.

Purpose: The study aimed to evaluate working environment for dental technician by measuring dust level, ventilation conditions and the use of personal protective equipment and to provide basic information required to improve working environment and develop health education programs for dental technician. Methods: A total of 240 dental technician who are registered with the Daegu Association of Dental technician and working at 34 dental laboratories participated in the study. And the dust level was measured at 21 different spots in 16 dental laboratories out of 34. Results: Of 34 dental laboratories, 31 (91.2%) were equipped with a ventilator, but the remaining 3 (8.8%) did not have a ventilator. By the number of ventilator, 1 to 3 ventilators were found in 22 dental laboratories (71.0%), 4 to 6 ventilators were in 7 laboratories (22.5%) and more than 7 ventilators in 2 laboratories(6.5%). According to the frequence of changing filters in dust collector, 20 dental laboratories (58.9%) changed filters every four weeks, 10 laboratories (29.4%) changed them every six weeks and 4 laboratories (11.7%) changed them every eight weeks. Of total respondents, 114 (61.3%) said they wore a mask all the time while working, 56 (29.6%) said they frequently wore a mask, 19 (10.1%) said they did not wear a mask. As for the type of masks, 159 (84.1%) used a disposable mask, 25 (13.2%) used a cotton mask and 5 (2.7%) used an anti-dust mask. For dust sat on their outfits while working, 102 (54.0%) shook their uniforms inside workplace to keep dust off the uniforms, 64 (33.9%) did not anything until they wash their uniforms and 23 (12.1%) shook their uniforms outside workplace to keep dust off the uniforms. Of total respondents, 182 (96.3%) had a particle in their eyes while carrying out grinding work. Based on the measurement of floating dust at workplace, 3 dental laboratories showed dust concentration exceeding the minimum level of 10 mg/$m^3$ allowed under the permit for environment. Of those, 1 laboratory had the dust concentration that was more than 1.5 times higher than the minimum level. Dust concentration was higher in laboratories that used a dust collector with 0.5 horse power and changed filters more than 3 weeks ago. Dust comprised of nickel (more than 70%), chrome (9%) and others. The mean chrome concentration was more than twice higher than the minimum permissible level of 0.5 mg/$m^3$. There were two laboratories that showed chrome concentration exceeding the level of 0.4 mg/$m^3$. Like dust concentration, chrome level was higher in laboratories that used a dust collector with 0.5 horse power and changed filters more than 3 weeks ago. There were six laboratories that had nickel concentration exceeding the minimum permissible level of 1 mg/$m^3$. Of those, one laboratory had nickel concentration that was more than three times higher than the minimum permissible level. Nickel concentration was also higher in laboratories that used a dust collector with 0.5 horse power and changed filters more than 3 weeks ago. Conclusion: It is not likely that heavy metal concentrations found in the study constitute respiratory dust. It is however necessary for health of dental technician to apply the Industrial Safety and Healthy Law to dental laboratories and make recommendations for the use of personal protective equipment, installation of a proper number of ventilators, more frequent change of filters in dust collector and improved ventilation for polishing work. At the same time, dental technician need education on how to use personal protective equipment and how to efficiently remove dust from their uniforms.

Objectives; The purpose of the present study is to investigate workplace satisfaction level of dental technicians and the differences between that of dental lab owner's and that of employed dental technicians, who are working in dental laboratories. Methods; Samples were comprised of 137 dental technicians working in dental laboratories. Data were collected through self-administered questionnaires and analyzed to frequency distribution, correlation, t-test and multiple regression analysis. Results; 1) Dental technicians generally are 'somewhat or a bit satisfied' with their workplace situations, regardless of position, sex, and individual career. 2) Mean values of 4 items out of 11 work situation factors of employed dental technicians were significantly lower than those of lab owner's. The 4 items are the openness of management, working environment, pay, and policy in promotion and raise. They would be sources of dissatisfaction and conflict. 3) Level of satisfaction was significantly correlated with 2 subordinate variables, i.e. working conditions and administration policy. There is a tendency that administration policy is a bit more important for lab owners, while working conditions are a bit more important for employed dental technicians. Conclusion; The employer-employee relationship of dental technicians seems to be sound, as no signs of troublesome problem is detected. But the discrepancy revealed in the above results is telling that there certainly exist some disagreement in the viewpoints of the two groups. It is necessary for the dental technicians to find ways to deal with the possible triggers of discord and discontent.

Online data can be explored for topics browsed by an unspecified population to detect professional information demands more quickly. The purpose of this study was to collect and analyze online questionnaires in order to find information required by dental hygienists. We analyzed the frequency of posting words after isolating nouns from questions of the Korean Dental Hygienists Association homepage's Q & A section, the Naver Knowledge-iN service, and a dental hygienists' online meeting site in Naver. We found that queries of the Korean Dental Hygienists Association's homepage were concentrated on education renewal and license notification. The queries about dental hygienists in the Naver Knowledge-iN service used words related to job or career choice, and the queries of the dental hygienist-affiliated site had many words related to dental practice, dental work, and turnover. This study showed that the information needs of unspecified dental hygienists varied depending on the online environment such as homepage, blog, and information service.

치과보조인력 정책의 현황을 확인하기 위하여 치과보조인력 공급 현황, 지역별 분포, 법적 업무, 근무환경 등의 측면에서 관련 선행문헌고찰 및 자료수집 및 분석을 실시하고, 관련요인을 고찰함으로써 우리나라 정책의 문제점을 도출하고자 하였다. 치과위생사 수의 급격한 양적 증가가 있었음에도 불구하고, 활동 수는 전체의 절반에도 미치지 못하고, 치과계는 여전히 치과위생사 인력난을 경험하고 있다. 치과위생사의 수행업무를 고려했을 때 치과진료보조 업무 수행을 위한 전문적 치과보조인력의 활용이 제한적이다. 또한, 대도시를 중심으로 치과위생사 분포가 편중되고, 치과위생사로만 구성된 치과의료기관 비율이 높기 때문에 지역별 치과보조인력 분포의 불균형을 해결하기 위한 방안 마련이 필요하다. 수행 업무 중 많은 비중이 의료기사법에 구체적으로 명시된 사항이 아니므로 해당행위의 적법성을 판단하는 기준이 모호하다. 치과위생사의 직업수명, 업무 효율성, 직업전문성 및 만족도가 감소함에 따라 직무소진이 빠르게 나타나고 있다. 치과위생사의 법적 업무와 실제 수행하는 업무와의 괴리, 직역 간 갈등의 심화는 정부 차원에서의 치과의료인력의 활용 계획과 방안이 부재하기 때문인 것으로 검토된다. 이에 대해 정부에서는 치과의료서비스 수요에 따라 치과위생사 인력의 역할을 정립하고, 필요 정책을 제도화하며, 인력을 적절하게 활용하기 위한 계획을 수립하기 위한 노력을 해야 한다.
