Objectives: This study aimed to understand the definitions, types, and principles of computer-aided design/computer-aided manufacturing (CAD/CAM) and scanners due to the introduction of digital workflows. Methods: This study was based on information from the government’s law and articles published in academic journals. Results: CAD/CAM is a technology that measures the shape three-dimensionally, saves it as data, designs it into the desired shape, and processes the product. Scanners, which are classified as intraoral and extraoral scanners, measure teeth and the intraoral environment three-dimensionally and convert them into three-dimensional (3D). A 3D printer is a machine that creates a 3D object by layering materials based on a 3D drawing. It can be classified into four types according to the method: extrusion, powder bonding, lamination, and photopolymerization methods. The most used 3D printer methods in dentistry are stereolithograhpy and digital light processing, and they are widely used in prosthetic, surgical, and orthodontic fields. Conclusions: As the dental system is digitized, it is expected that the government will classify the dental hygienist scope of work and the universities will reflect the curriculum; it is necessary to develop excellent dental hygienists, diversify the educational pathways, and establish policies to meet the needs of the increasing number of patients.

Objectives: The purpose of this study was to provide basic data that would inform the direction of oral rehabilitation and how to expand of the role of dental hygienists in Japan. Methods: A systematic literature review was conducted on the role of dental hygienists in the field of oral rehabilitation in Japan. Results: Japan has been making academic and practical developments in the field of oral rehabilitation for over 30 years, and has been gradually implementing a fee support policy since the 1990s. In addition, Japan has been operating a dental hygienist system specializing in oral rehabilitation since 2006. The related work was being carried out with the dental hygienist’s expertise in the field of rehabilitation medical treatment secured. Dental hygienists work full-time at long-term care facilities for the elderly in addition to conducting oral care activities under the local comprehensive care system, in the areas of convalescence and acute rehabilitation, as well as in the field of visiting rehabilitation. It can be seen that, in the field of nursing care, they are specialized in oral care tasks for the elderly. Conclusions: In the future, a policy and related fee system should be gradually prepared to expand the role of dental hygienists in the field of oral rehabilitation that can contribute to improving oral health linked to systemic diseases.

Objectives: The COVID-19 outbreak has resulted in changes in the instructional methods used in kindergartens and daycare centers to prevent viral infections. This study aimed to investigate the changes in oral health care for children before and during COVID-19 and the perceptions of kindergarten and daycare center teachers about oral health care. Methods: The study subjects were 189 teachers of kindergartens and daycare centers in charge of children aged 3 to 5. The data for the analysis were collected through an online survey. Frequency analysis and the chi-squared test were used for statistical analysis. Results: Compared to before COVID-19, the frequency of tooth brushing after lunch, the number of oral health education and regular oral examinations, and the rate of childcare teachers’ experiences with oral health education had decreased during COVID-19. In addition, educators in kindergarten and daycare centers responded that an oral health officer at a public health center was the most desirable oral health educator. Conclusions: During the COVID-19 pandemic, the oral health care of children in kindergartens and daycare centers has declined. Efforts are needed to restore it by educating people about oral hygiene care and oral health education, both at home and in kindergartens and daycare centers.
