Objectives: The purpose of this study was to examine the perception of dental hospital accreditation and the awareness and practice of infection control in dental hygienists. Methods: A self-reported questionnaire was completed by 238 dental hygienists working at dental hospitals in Gwangju Jeonnam and analyzed from October 24, 2016 to September 22, 2017. Data were analyzed with the independent t-test, one-way analysis of variance, Pearson's correlation analysis, and multiple regression analysis using the Statistical Package for the Social Sciences software, version 21.0. Results: Compared to non-accredited dental hospitals, all three variables were high for accredited dental hospitals. In accredited dental hospitals, healthcare accreditation expectancy effects correlated to awareness (r=0.407) and practice (r=0.533) of infection control, and awareness of infection control correlated to its practice (r=0.725). In non-accredited dental hospitals, healthcare accreditation expectancy effects correlated to awareness of infection control (r=0.239), and awareness of infection control correlated to its practice (r=0.481). Accredited dental hospitals showed healthcare accreditation expectancy effects (${\beta}=0.258$) and awareness of infection control (${\beta}=0.556$), and non-accredited dental hospitals were influenced by the number of employees (${\beta}=0.567$) and awareness of infection control (${\beta}=0.376$). Conclusions: It is necessary to develop efficient and systematic infection control programs to improve the awareness and practice of infection control in dental hygienists and patient's safety in the clinical field.

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.

An intraoral spectral domain optical coherence tomography (SD-OCT) system has been developed, using a custom-built hand-held scanner and spectrometer. The hand-held OCT probe, based on a microelectromechanical systems scanner and a self-built miniaturized drive circuit, had a field of view sufficient for dental diagnosis. The spectrometer using a fabricated f-theta lens provided the image depth required for dental diagnosis. The axial and transverse resolutions of the OCT system in air were 7.5 ㎛ and 12 ㎛ respectively. The hand-held probe could scan an area of 10 × 10 mm², and the spectrometer could image along a depth of 2.5 mm. To verify the utility of the developed OCT system, OCT images of tooth hard and soft tissues were acquired, and a user-interface program for diagnosis was developed. Early caries and microcracks that were difficult to diagnose with existing methods could be found, and the state of restoration could be observed. Measuring the depth of the gingival sulcus, distinguishing subgingival calculus, and detecting an implant under the gingiva suggested the possibility of the SD-OCT system as a diagnostic for dental soft tissues. Through the presented OCT images, the capability of the developed SD-OCT system for dental diagnosis was demonstrated.

Objectives: This study aimed to provide basic data to lay the groundwork for the introduction of an advanced dental hygienist system by sampling dental hygienists' views about the system. Methods: A nationwide questionnaire survey was conducted targeting 857 dental hygienists working at dental hospitals and clinics, local health institutions, and educational institutions. The collected data were analyzed using frequency analysis, t-test, one-way analysis of variance (ANOVA) (Duncan as post-analysis), and crossover analysis. Results: The average interest level in the advanced dental hygienist system was 3.83±0.95 points. The necessity by field was confirmed to be the highest during dental hygiene for the elderly and persons with disabilities. The working experience necessary for becoming a specialized dental hygienist is 5.56±2.99 (years). The education period necessary for becoming a specialized dental hygienist is 77.30±77.61 (hours). The work authority level for an advanced dental hygienist was indicated to be 50 respondents (5.8%), who said they required direct guidance from a dentist, 313 respondents (48.2%) who said they needed indirect guidance from a dentist, 200 respondents (23.3%) who said OK when given an advanced dental hygienist's separate judgment, 194 respondents (22.6%), who said that the authority must be varied depending on the work. Conclusions: The interest and need of the advanced dental hygienist system were proven to be high and are expected to be applied to basic data for the introduction and settlement of the system.

Objectives : This study was to examine the social value of dental hygienists, their values about the health system and the relationship of all the related variables. Methods : The subjects in this study were 205 dental hygienists who worked in dental clinics and hospitals on Seoul. A survey was conducted from August 12 to October 15, 2010. The questionnaire consisted of nine items about general characteristics, two items about social values and 11 about values of the health system. The items related to social values and values of the health system were prepared by translating the items used in David et al's study, and the Cronbach alpha coefficient of those items respectively 0.80 and 0.76. Results : The dental hygienists got 3.94 in social values, which was above the average. In terms of values about the health care system, their values of the treatment delivery system(3.92) rated highest, followed by values of patient rights(3.79) and values of institutional restrictions(3.25). Their socal values had a closest positive correlation to their values of the treatment delivery system, and their values of patient rights had a strong positive correlation to those of the treatment delivery system and was positively correlated to those of institutional regulations as well. And there was a positive correlation between their values of the treatment delivery system and institutional regulations(r=.276). Conclusions : The above-mentioned findings illustrated that the social values of the dental hygienists had a positive correlation to their values of the health system. Therefore the kinds of educational programs that help dental hygienists to build their social values and values of the health system should be developed to improve their job efficiency as oral health experts.

The increasing cross-border mobility of dental school or dental hygiene students, educators, practitioners, programs and providers takes challenges for existing national quality assurance and accreditation frameworks and bodies, as well as for the systems for recognizing foreign qualifications. The new dental hygiene accreditation system was introduced to encourage the improvement of dental hygiene programs, to ensure the quality of education and, most of all, to establish an internationally compatible system of evaluation and accreditation. The accreditation procedure takes 1 year to complete. The result of the accreditation is released after evaluation via self-study report, site visit, preliminary draft report, responses from the institution and the results from the conciliation and review committees. The result from the accreditation procedure is either 'accreditation' or 'no accreditation'. Accredited schools receive one of several statuses following the evaluation. These are next general review, interim report and interim visit or suspension. Dental healthcare quality is not improved instantaneously, but instead gradually through continuous communication within the dental field. For this accreditation system to be successful, the following are essential: the accreditation agency should adopt hygiene education accreditation; it needs to become financially independent and managed efficiently; the autonomy and regulations surrounding the system need to be balanced; the professionalism of the system is ensured; and the dental field which includes not only dental program, but also hygiene program, needs to play an active role in the operation of the system.

Background: People with special needs tend to require diverse behavioral management in dentistry. They may feel anxious or uncomfortable or may not respond to any communication with the dentists. Patients with medical, physical, or psychological disorders may not cooperate and therefore require sedation (SED) or general anesthesia (GA) to receive dental treatment. Using the healthcare big data in Korea, this study aimed to analyze the trends of SED and GA in special needs patients undergoing dental treatment. It is believed that these data can be used as reference material for hospitals and for preparation of guidelines and related policy decisions of associations or governments for special needs patients in dentistry. Methods: The study used selected health information data provided by the Korean National Health Insurance Service. Patients with a record of use of one of the eight selected drugs used in dental SED between January 2007 and September 2019, those with International Classification of Diseases-10 codes for attention deficit hyperactivity disorder (ADHD), phobia, brain disease, cerebral palsy, epilepsy, genetic disease, autism, mental disorder, mental retardation, and dementia were selected. The insurance claims data were analyzed for age, sex, sedative use, GA, year, and institution. Results: The number of special needs patients who received dental treatment under SED or GA from January 2007 to September 2019 was 116,623. Number of SED cases was 136,018, performed on 69,265 patients, and the number of GA cases was 56,308, implemented on 47,257 patients. In 2007, 3100 special needs patients received dental treatment under SED while in 2018 the number of cases increased 6 times to 18,528 SED cases. In dentistry, ADHD was the most common disability for SED cases while phobia was the most common cause of disability for GA. The male-to-female ratio with respect to SED cases was higher for males (M : F = 64.36% : 35.64%). Conclusion: The application of the SED method and GA for patients with special needs in dentistry is increasing rapidly; thus, preparing guidelines and reinforcing the education and system are necessary.
