Recently, there have been improvements in diagnostic methods for the assessment of early caries lesions. The reason is that dental professionals are seeking methods to reliably detect incipient dental caries and to remineralize them. This review examines the literature on principles, theoretical background, and history of the Quantitative Light-Induced Fluorescence (QLF) system (Inspektor Research Systems BV, The Netherlands). Furthermore, this paper discusses the potential application of QLF system to clinical practice for educational purpose, enabling dental hygiene students to perform oral health assessment using the QLF system. In addition, the clinical application of QLF system can motivate patients by providing additional visual information about caries and bacterial activity. The evidences on validity and reliability of the QLF system for detection of longitudinal changes in de/remineralization and caries were examined. The QLF system is capable of monitoring and quantifying mineral changes in early caries lesions. Therefore, it can be used to assess the impacts of caries preventive measures on the remineralization and reversal of the caries process. And the QLF system is a very promising equipment to assess educational effectiveness for dental hygiene students in their learning process. In conclusion, the QLF system is the most effective technology for more sensitive staging of caries and treatment without surgical intervention.

Objectives: The aims of this study were to analyze the job stress of clinical hygienists according to their positional system and to confirm its relevance. Methods: Seven hundred seventy six clinical dental hygienists participated in this survey. The questionnaire items consisted of general characteristics, working environment, and job stress. The data analysis was performed using IBM SPSS statistics ver.23.0 software. Results: Among the job stresses, the stress on the job demands was the highest with 63.4 points, and the stress on interpersonal conflict was the lowest with 34.6 points. The total score of job stress was the highest in the 26-30 year-old age group, and major stress factors in this group were job insecurity, organizational system, and lack of reward. Team members were more stressful about insufficient job control, organizational system, and lack of reward than team managers, while team managers were more likely to score interpersonal conflict. The dental hygienists in the hospitals that did not have the positional system got more stressed in the insufficient job control, organizational system, and lack of reward area. Conclusions: The presence of positional system was related to job demand, insufficient job control, organizational system, and lack of reward. Structural efforts such as establishing a proper positional system in dental clinics will be needed to control job stress in the clinical dental hygienists.

Dental caries has been widely prevalent with presence of cavitation on teeth. For the last several decades, the prevalence of dental caries in developed countries has rapidly decreased so there has been needed a new and detailed diagnostic guideline to differentiate the severity of dental caries, especially for early status of caries. The cariology specifically requires the development of an integrated definition of dental caries and uniform systems for measuring the caries process in the fields of clinical diagnosis and treatment, epidemiological researches, and dental education and so forth. The international Caries Detection and Assessment System (ICDAS) optically measures the enamel surface changes and potential histological depth of carious lesions by relying on surface characteristics of teeth. ICDAS is a visual classification system that was developed to diagnose the subtle changes of enamel surface, predict the progress direction of early caries, allow standardized data collection in relation to caries in different settings, and to enable better comparison of oral health between countries worldwide and research studies.

Objectives: The purpose of this study was to investigate the opinions of Korean dental hygienists on the Korean advanced dental hygienist system in Korea. Methods: The survey was conducted on 328 dental hygienists working at dental clinics and hospitals in Seoul, Gyeonggi-do, Incheon, and Chungcheong-do. Collected data were analyzed with the frequency analysis, independent-samples t-test, and one-way analysis of variance after their reliability and validity were verified through the reliability, exploratory factor, and confirmatory factor analyses. Results: Respondents preferred sectoral advanced dental hygienists to integrated advanced dental hygienists, but 47.0% of respondents did not respond to this questionnaire item. To become an advanced dental hygienist, 'more than 5 years but less than 8 years' of clinical experience was appropriate according to 45.7% of the respondents and 'more than 30 h but less than 40 h' of training period was appropriate according to 25.9% of the respondents. Respondents thought that the duration of the training period for advanced dental hygienists would be directly proportional to expectations from the effect of advanced dental hygienists (p=0.023). Further, respondents who were usually interested in advanced dental hygienists showed higher expectations from the role (p<0.001) and effect (p<0.001) of advanced dental hygienists than those who were not interested. Conclusions: This study suggests various implications of the introduction of the advanced dental hygienist system in Korea.

Purpose: The purposes of this study were to develop a workstation computer that allowed intraoperative touchless control of diagnostic and surgical images by a surgeon, and to report the preliminary experience with the use of the system in a series of cases in which dental surgery was performed. Materials and Methods: A custom workstation with a new motion sensing input device (Leap Motion) was set up in order to use a natural user interface (NUI) to manipulate the imaging software by hand gestures. The system allowed intraoperative touchless control of the surgical images. Results: For the first time in the literature, an NUI system was used for a pilot study during 11 dental surgery procedures including tooth extractions, dental implant placements, and guided bone regeneration. No complications were reported. The system performed very well and was very useful. Conclusion: The proposed system fulfilled the objective of providing touchless access and control of the system of images and a three-dimensional surgical plan, thus allowing the maintenance of sterile conditions. The interaction between surgical staff, under sterile conditions, and computer equipment has been a key issue. The solution with an NUI with touchless control of the images seems to be closer to an ideal. The cost of the sensor system is quite low; this could facilitate its incorporation into the practice of routine dental surgery. This technology has enormous potential in dental surgery and other healthcare specialties.

Background: Despite the demand for greater competence of dental hygienists in recent times, and the consequent standardization of systems in the organizations, there is a lack of a proper system for hierarchal positions of dental hygienists. The aim of this study was to identify the tasks performed by Korean dental hygienists in various work settings and hierarchal positions to suggest a standardized system for task-related hierarchal positions. Methods: A survey was conducted by sending questionnaires to 966 dental hygienists, and responses from 757 participants were included in the final analysis. The survey comprised questions regarding participants' general characteristics, tasks, current positions, and the internal policies or standards of the respective organizations to define these positions. The participants' positions were analyzed as frequency and cross-sectional analysis with respect to their general characteristics, their place in the organizational charts, the size of their workplaces, and differences in the tasks performed. Results: Data showed that 82.6% of the hospitals and clinics in Korea have organizational systems to determine the positions, and there was a significant difference in the systems according to the size of the health facility (p<0.05). The standards or policies used to define positions within general or university hospitals were determined by internal regulations or bylaws, whereas work experience was the major determinant of positions in smaller dental hospitals or clinics. The main tasks performed by dental hygienists in Korea were dental assistance (81.2%), routine dental hygiene tasks (53.4%), and administrative tasks, such as reception and billing (46.1%). Conclusion: Most dental hygienists in Korea are actively involved in dental assistance. Therefore, their specific tasks and responsibilities should be standardized more effectively. The data obtained from this study can be used to establish a standardized position system.
