General status of pediatric dentistry in Korea is to conduct vigorous academic activities and specialized medical care centering the Korean Association of Pediatric Dentistry (KAPD) that has about 1,000 pediatric dentists as members, pediatric dentistry departments of 11 Colleges of Dentistry, numbers of pediatric dentistry training institutions and private clinics specialized in children. From 1996, the accredited pediatric dentists were produced by the KAPD and from 2008, the state began to produce the accredited pediatric dentists. Since then, doctors with expertise in pediatric care had opened private clinics in addition to the university hospitals, it became the basis of a momentum to deepen the specialty of pediatric dentistry. The Dentistry community of Korea is going through rapid and profound changes recently, and the underlying reasons for such changes can be classified largely into a few categories: (1) Decreasing population and structural changes in population (2) Increase in numbers of dentists, (3) Changes in the pattern of dental diseases and (4) Changes in medical environment. In Korea, the children population in the age range of 0 ~ 14 years old had been decreased by 2 million in 2010 compared to that of 2000 due to reduction of birth rate. The current population of children in the age range of 0 ~ 4 years old in 2010 takes up 16.2% of the total population, but it is estimated that such percentage would decrease to 8.0% by 2050. Such percentage is largely behind the estimated mean global population of 19.6% by 2050. On the other hand, the number of dentists had been largely increased from 18,000 in 2000 to 25,000 in 2010. And it is estimated that the number will be increased to 41,000 by 2030. In addition, the specialized personnel of Pediatric dentistry had been shown as increased by 2.5 times during past 10 years. For the changes in the pattern of dental diseases, including dental caries, each df rate of 5 years old children and 12 years old children had been decreased by 21.9% and 16.7% respectively in 2010 compared to 2000. Each df Index also had been decreased by 2.5 teeth and 1.2 teeth respectively. The medical expenditure of Korea is less than that of OECD and more specifically, the expenditure from the National Health Plan is less than OECD but the expenditure covered by households is larger than OECD. These facts indicate that it is considered as requiring the coverage of the national health plan to be reinforced more in the future and as such reinforcement needs continuous promotion. In medical examination pattern of Pediatric dentistry, the preventive and corrective treatment were increased whereas the restorative treatment was decreased. It is considered that such change is caused from decrease of dental caries from activation of the prevention project at national level. For the restorative treatment, the restorations in use of dental amalgam, pre-existing gold crowning and endodontic treatment had been decreased in their proportion while the restorative treatment in use of composite resin had been increased. It is considered that such changes is caused by the change of demands from patients and family or guardians as they desired more aesthetic improvement along with socio-economic growth of Korean society. Due to such changes in dentistry, the pediatric dentistry in Korea also attempts to have changes in the patterns of medical examination as follows; It tends to implement early stage treatment through early diagnosis utilizing various diagnostic tools such as FOTI or QLF. The early stage dental caries so called white spot had been included in the subjects for dental care or management and in order to do so, the medical care guidelines essentially accompanied with remineralization treatment as well as minimally invasive treatment is being generalized gradually. Also, centering the Pediatric dentists, the importance of caries risk assessment is being recognized, in addition that the management of dental caries is being changed from surgical approach to internal medicinal approach. Recently, efforts began to emerge in order to increase the target patients to be managed by dentists and to expand the application scope of Pediatric dentistry along with through such changes. The interest and activities of Pediatric dentists which had been limited to the medical examination room so far, is now being expanded externally, as they put efforts for participating in the preventive policy making process of the community or the state, and to support the political theories. And also opinions are being collected into the direction that the future- oriented strategic political tasks shall be selected and researches as well as presentations on the theoretical rationale of such tasks at the association level.

Objectives: This research was conducted to recognize dental health care employees' awareness of patient safety culture and to examine the association between awareness of patient safety culture and patient safety activities. Methods: The subject of this research includes the dental health care employees from 11 different dental hospitals in the nation, dental offices in the 6 different general hospitals in Seoul, and 4 different private dental offices in 2014. A self-reported questionnaire was completed by 485 dental health care employees from March 17 to April 3, 2014. Multiple regression models were used in the analysis. Results: First, the dental health employees' awareness of patient safety culture was 3.25 on average. The extent of patient safety activities was 2.75. The behavior of the supervisor/manager and the adequate explanation showed positive correlation with r=0.213 (p<0.001). The process of communication and the preventative inspection of the medical equipment showed negative correlation with r=-0.258 (p<0.001), and especially the awareness of patient safety culture and the infection control exercise showed the most significant correlation (r=0.293, p<0.001). Second, hospital environment factor of patient safety perceptions positively were related to most of patient safety management activities after controlling several covariates. Conclusions: The result of this research showed that most of the patient safety culture perceptions positively were correlated with patient safety activities. We also found that proper hospital environment, simple communication process, and positive perceptions for patient safety level were more likely to perform patient safety management activities after controlling several covariates. Improving the patient safety perceptions of dental hospital workers is an important consideration.

There have recently been an increasing number of reports claiming that the periodontal disease, the most typical oral disease, is closely associated with various systemic diseases such as cardiovascular disease. Therefore, it is imperative to explore the methods that can ensure effective and cost-effective monitoring of periodontal disease in specific population groups, as well as individuals in the electronic medical record environment. However, traditional periodontal examination methods, such as periodontal probe, are considerably demanding and time-consuming for dental specialists, and furthermore, cause the risk of bacteremia as they are invasive procedures. Thus, the objective of this study was to validate the capability of new method for screening the periodontal disease using the self-reported questionnaire for periodontitis which is the non-invasive procedure to replace radiography.

The setting of dental hygiene clinics is very important to dental hygiene education, which is the place not only to educate students but also to care clients. The purpose of this study is to provide basic research material for improvement of dental hygiene care system in dental hygiene clinics by analyzing the client satisfaction. A questionnaire survey by means of self-entry method was conducted to find out satisfaction of the client, who was visited to the dental hygiene clinics in the department of dental hygiene, Yonsei University. An analysis of frequency, one way ANOVA and T-Test were performed through SPSS 12.0K program. 1. Most clients were mainly composed of students in Wonju College of Medicine. 2. The clients visited for scaling(85.8%) and oral examination(9.73%) were much than treatment(4.42%). 3. Clients aged 21 to 25 were relatively lower in satisfaction with the facilities, system, attitude than any other ages. 4. The dental hygiene students are the lowest group in satisfaction with the facility, system, attitude than medical and nursing students. 5. The clients satisfaction with dental hygiene clinics was decreased in reverse proportion to visiting frequency. 6. Most of the clients pointed out the problems of appointment system(54.0%) and fee(23.0%), which should be improved than any other operation conditions. 7. Most of the clients were not satisfied with chair time and pain during care. 8. Most clients recognized to receive the better care service than other dental offices(81.3%). Especially, they paid attention to oral health education using phase-contrast microscope. 9. Many clients were dissatisfied with facilities of the dental hygiene clinics(71.7%). The problems of appointment system(54.0%) and chair time of dental hygiene care services(63.6%) had also inconvenienced to clients. The dental hygiene clinics in school play a crucial role in dental hygiene education to foster the student to be competent as a professional dental hygienist in the future. Therefore, well-organized dental hygiene care program based on dental hygiene process is essential. It is also required to improve the environment of dental hygiene clinics including facilities, appointment system and fee etc.

Objectives: Enterococcus faecalis is a gram positive diplococci, highly versatile and a normal commensal of the gut microbiome. Resistance to vancomycin is a serious issue in various health-care setting exhibited by vancomycin resistant Enterococci (VRE) due to the alteration in the peptidoglycan synthesis pathway. This study is thus aimed to detect the VRE from the patients with root caries from the clinical isolates of E. faecalis and to evaluate the in-silico interactions between vanA and the Aegles marmelos bio-compounds. Methods: E. faecalis was phenotypically characterized from 20 root caries samples and the frequency of vanA and vanB genes was detected by polymerase chain reaction (PCR). Further crude methanolic extracts from the dried leaves of A. marmelos was assessed for its antimicrobial activity. This is followed by the selection of five A. marmelos bio-compounds for the computational approach towards the drug ligand interactions. Results: 12 strains (60%) of E. faecalis was identified from the root caries samples and vanA was detected from two strains (16%). Both the stains showed the presence of vanA and none of the strains possessed vanB. Crude extract of A. marmelos showed promising antibacterial activity against the VRE strains. In-silico analysis of the A. marmelos biocompounds revealed Imperatonin as the best compound with high docking energy (-8.11) and hydrogen bonds with < 140 TPSA (Topological polar surface area) and zero violations. Conclusion: The present study records the VRE strains among the root caries with imperatorin from A. marmelos as a promising drug candidate. However the study requires further experimentation and validation.

This study researched into literature materials in order to utilize basic data on job importance in dental coordinator, and analyzed questionnaire on job importance in dental coordinator for about 2 months from August and September in 2008 targeting dental hygienists and other manpower for dental hospitals & clinics where are located in D region and neighboring region. The following are the results: 1. Dental hospital & clinics where dental coordinators work were surveyed to be totally 66.9%. Dental coordinators were indicated to be 71.1% as for dental hospital$^{\circ}{\S}$clinic(women), and to be 28.4% as for a case with none. There was significant difference according to final academic degree and working place(P<.001). 2. License holders(women) for dental hygienist as dental coordinator accounted for 39.8%. The opposite case accounted for 60.2%. A case of doing duty of dental coordinator given not dental hygienist was indicated to be high. There was significant difference according to working place(p<.01). 3. The task importance on job that a dental coordinator directly performs was indicated to be averagely 3.24, thereby having been recognized to be important. 4. As for the recognition on job importance according to working-year number, it was indicated to have higher recognition on task importance in the more working-year number regarding customer management(p<.01), organization management(p<.05), and self-management(p<.01). 5. Given seeing difference in recognition on task importance according to medical institution, it was indicated to be 3.34 for dental clinic and 3.25 for dental hospital. Thus, the task importance was indicated to be slightly high in a person who works for dental clinic. There was no significant difference. In light of the above results, in order to educate dental coordinator who can successfully perform a role at dental hospital & clinic, a dental hygienist is required who is equipped with dental-clinic career rather than a person without a major. A professionally educational program for dental coordinator needs to be developed. Even in a dental coordinator's task, there is necessity for the curricular development and the specialized education.

Objectives : This research was conducted to find the subjective symptoms of musculoskeletal system for main jobs and job posture. Methods : A survey was conducted from September 15, 2011 to October 7, 2011 and 357 dental hygienists were responded. The survey was consisted of the working environment and medical equipments, psycho-social characteristics, health habits and education, job posture, subjective symptoms of musculoskeletal system pain, and so on. Results : In the survey on the frequency of job posture of dental hygienists by jobs, said they cast down or tilt their head by 15 degrees or more or twist or bend their back. The result of the analysis on the subjective symptoms of musculoskeletal system by main job showed that they experienced a pain in neck, shoulder, and back, although the order differed. The order of subjective symptoms of musculoskeletal system for casting down or turning head by 15 degrees or more, twisting or bending back, having shoulders not parallel to the ground, sitting at the end of a chair, and supporting the whole body with one leg or pressing on a pedal for treatment was from the shoulders to the neck to the back. The order of subjective symptoms of musculoskeletal system for having arms too far from the body or hunching for treatment and bending wrists inward or outward for treatment was from the shoulders to the back to the neck. Conclusions : Due to the characteristics of the job which requires one to have a proper view of a patient's oral cavity, most of the postures included casting down of head or bending of back. Therefore a development of new postures is needed to replace the existing job postures which pressure the musculoskeletal system. And shift rotation can be used as a preventive measure.
