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.

Education should consider the social consensus that changes according to the times and the social environment, and it is also necessary to consider the technically useful subjects. We collected and reported the 4-year course curriculum of dental hygiene when Korean dental hygiene education has continued over 50 years. Each 4-year course curriculum was collected by searching each university website, or requested by email. The curriculum of 23 among 27 schools was collected. According to the classification of dental hygiene in the dental hygienist national examination classification or the Korean society of dental hygiene science, the subjects of the course were divided into clinical dental hygiene, clinical dental treatment support, basic dental hygiene, social and educational dental hygiene, and collected 23 curriculum courses. The average major curriculum was 104.9 credits and the average number of subjects in major courses was 34.3. The average subjects' number of clinical dental hygienic courses was 33.9 (37.5% of the total major credits), clinical dental treatment support was 30.6 (30.2% of the total major credits), basic dental hygiene was 21.8 (20.8% of the total major credits), and social and educational dental hygiene courses was 13.6 (13.0% of total major credits). Integrated subjects' name in clinical dental hygiene was used in all schools of the survey, such as clinical dental hygiene education (and practice), comprehensive dental hygiene education, and integrated dental hygiene. There were 13 schools (56.5%) that use the integrated name in clinical dental treatment support, such as clinical dentistry. There were 14 schools (60.9%) to open dental clinic management, and 22 schools (95.7%) to open national health insurance claims. The basic dental hygiene curriculum maintained the title of each subject and social and educational dental hygiene education was established in most schools, such as community dental health, oral health statistics, and oral health education. Other subjects were English conversation in dental clinic (8 schools) education, clinical dental treatment support, basic science in dental hygiene, social and educational dental hygiene. We knew the clinical dental hygiene and clinical dental treatment support were changing into the integrated subjects, and most schools run dental hygiene research.

To improve esthetics and gain beautiful smile, the maxillary anterior dentition is crucial. Through alteration of height, arrangement or color of the maxillary incisor, we can rehabilitate the esthetic smile. The perception of dental esthetics is highly subjective. Personal perceptions or judgement of dental esthetics is highly related with each individual's experience and social and cultural environment. However, there have been many efforts to establish the criteria for generally accepted esthetic norm, in order to increase the predictability of restorative treatment. For maxillary anterior restoration, not only a single tooth, but also the compositions around tooth such as facial form, lips and gum and their relationships have to be considered to create harmonious smile. It can be determined as esthetic restorations when in consonance with facial form and structures that frame the restorations. In this review article, several guidelines that are generally accepted and useful to assess the esthetics and communicate with patients and technicians will be discussed.

The purpose of this study is to discuss the economic outlook of dentistry in relation to pessimistic economic perspectives of Korea and to present subsequent solutions. The expectation of the future economic growth rate of Korea is gloom with not only a love rate of increase in population due to an aging society and a low birthrate, but also with a declined number of productive populations. Moreover, the future of dentistry in Korea is obscure. Even with a dwindling population growth, an average of 750 new dentists graduate from dental school every year. The 30-35% of the new graduates practice in public hospitals; and 65~70% of them open up their own private practices, However, unlike in the past, the occurrence of dental practice bankruptcy has been increasing with a competitive environment, excessive initial investment, knowledgeable patients, and etc. Therefore, it is essential to re-evaluate the number of new graduates. Also, it is necessary to supply a greater number of public hospitals with newly licensed dentists, who have various clinic experience, participate in research and development, and experience appropriate hospital management skills.
