Objectives: In the field of dental hygiene, infections pose a serious problem. This issue has left many patients and dental staff exposed to microbes with potentially far-reaching effects. The purpose of this study was to find solutions which could improve Dental health policies and promote improved methods for the control of infections. This survey was conducted between March 3, 2008 and March 30, 2008, in the metropolitan area. The research was carried out in dental clinics and dental hygienists were surveyed through a questionnaire. Methods: Collected data was examined using the SPSS 14.0 program, using frequency, mean and standard deviation analysis, T-test, one-way ANOVA, Scheffe`s test and Duncan`s test. Further analysis was given using Logistic Regression. Results: The Performance of Infection Control by dental hygienists in Dental Clinics was shown at 2.96±0.42. Disinfection, sterilization and the wearing of masks is high at 3.65±0.64, 3.64±0.65. The perception of the importance of infection control is higher among dental hygienists than dentists. Of the dental hygienists surveyed, 83.9% were exposed to at least one accident while at work. Age and years of experience were important in relation to infection control practices. The rate of infections and the number of accidents experienced related to the dental hygienists performance of infection control. The performance of infection control is influenced by the dental hygienists own perceptions, and the perceptions of their dentists. The dental hygienist`s working conditions and their beliefs related to infection control were shown to influence their performance of infection control practices. Conclusion: At the conclusion of this investigation, it was determined that systematic refresher training of infection control should be delivered through further education and various media. Dental health care workers should be encouraged to practice these action items presented in the training. For successful implementation of infection control in every dental health-care setting, it is highly demanded that effective safe-guard tools, strategic support and standardized action items against infection problems are developed.

김정신 ( Jungshin Kim ),임오연 ( Yim Ohyon ) 한국공간디자인학회 2019 한국공간디자인학회논문집 Vol.14 No.7

(Background and Purpose) Recently, hospitals with medical technologies are increasingly experiencing secondary infections, cross-contamination and hospital infections caused by new bacteria, which were unexpected in the treatment of disease. In particular, dentists are close to the contact distance between the patient and the medical staff, and are mainly exposed to pathogens, which are exposed to hospital infections. Therefore, the importance of hospital infection should be considered in determining the shape and space composition of the dentist. This study analyzes the academic research related to the spatial design of dental clinics and analyzes the spatial compositional characteristics of the cases of equilibrium in Korea centering on the area and moving lines, and emphasizes the importance of infection control space composition in future dental clinics. Is the purpose of the study. (Method) The subject of this study was the indoor space of the domestic dental clinic. The results of the composition of infection control space of the dental clinic were derived by investigating and analyzing the disinfection space, the treatment space and the area of the operating room in the plan of the interior space of the dental clinic. As an analysis factor for case analysis, the characteristics of infection control space composition are summarized by analyzing the characteristics of the movement lines and space types of the infection management space that supports the treatment space, focusing on the various literatures and research contents from previous studies. (Results) In general, the facilitation of hand hygiene in hospitals, regardless of the size of the equilibrium, was reflected in the plan. All types of dental offices that use stand-alone type faucets are installed in facsimile spaces. Some open clinics do not actively install faucets in proportion to the number of dental chairs. Faucets were planned indoors, except for one of the dental clinics with operating rooms. The dental clinic equipped with the preliminary room had a faucet planned in every space. Seven dental clinics had separate entrances to separate the contaminated and clean lines of the disinfection room. About half of the councils actively reflected plans for infection control space. (Conclusions) Recently, the level of consciousness of the public's medical environment demands a comfortable and safe space considering the physical and emotional conditions of the patients as well as the practitioners, not just the environment with facilities that do not interfere with the medical treatment. An attempt is needed to effectively address the guidelines for infection control, which should be addressed first in the dentist's space plan, even in the physical environment of the size of the space and efficient management of human resources.

Objectives: This study aimed to investigate the perception of dental infection-control coordinator (DICC) among dental hygienist and determine whether there is a difference in perception depending on the type of work. Methods: Dental hygienists working at the dentistry were conveniently extracted and distributed to 351 patients, and the data of 320 patients were finally analyzed. The chi-square test was conducted to determine the difference in perception of the DICC according to the type of work, and the one-way ANOVA was performed to determine the difference in the perception of DICC tasks. A p-value of <0.05 was statistically significant. Results: General hospitals and university hospitals (100%), dental hospitals (95.8%), and dental clinics (86.6%) showed the highest awareness of the need for DICC. The dental clinics had the lowest level of awareness regarding the duties of the DICC, and dental hospitals and clinics were in different areas with different levels of awareness regarding infection controlrelated administrative support areas (3.98-4.21 and 3.79-4.12 of 5). Conclusions: Because of a difference in perception regarding the work of DICC according to the type of work, dental organizations should establish the tasks of DICC and develop an education program for a person in charge based on this.

The purpose of this study was to study dental hygiene department students` management of infection and their attitude toward infection. This study was conducted from August 24, 2009 to September 20, 2009. 269 sophomore and junior college students enrolled in the department of dental hygiene from schools located in Gyeonggi-do and Gangwon-do participated in the study. A self-administered questionnaire survey was conducted, and the results of the study are as follows: 1. As for dental hygiene department students` recognition of the causes of infectious diseases, 80.7% of the respondents said hepatitis B was the infectious disease highly likely to occur in laboratories. 35.3% was correct about the antecedent variables of infection in the workshop, 24.9% about the oral symptoms of HIV and 18.6% about the diseases induced by HBV. The recognition rates were generally low. 2. About whether the respondents ask patients questions about infectious diseases, 80.7% of them answered Yes, but only 56.2% of them said they do so every time, and 17.8% of them said they never do so. 3. As far as washing hands to prevent infectious diseases is concerned, 97.4% of the respondents said hand washing helps prevent infection. 72.5% of them said they wash their hands every time before they practice on a patient, while 84.0% of them said they washed their hands after the lab practice. 90.7% said they use liquid soap containing anti-microbial agents, and 81.8% of them said they use paper towels. 4. With regard to protective gear for prevention of infectious diseases, 98.9% of the respondents said it is desirable to use disposable protective gear for each patient. When it comes to what they actually used as protective gear, 91.1% said aprons, 89.2% gloves, and 87.7% masks. However, a low percentage of the respondents actually use goggles and replace masks when they got damp, 11.2% and 24.2% respectively. 5. As for treating the surface of equipments to prevent infectious diseases, most of the respondents exhibited a high recognition rate. Relative fewer respondents actually treat the surface of equipments than those respondents who are aware of the need to do so. A high percentage of the respondents also said they use alcohol sponge to treat the surface of each equipment in order to prevent infectious diseases.

Park, Jinyoung,Lee, Jae-Yeol,Hwang, Dae-Seok,Kim, Yong-Deok,Shin, Sang-Hun,Kim, Uk-Kyu,Song, Jae-Min Korean Association of Maxillofacial Plastic and Re 2019 Maxillofacial Plastic Reconstructive Surgery Vol.41 No.-

Background: The purpose of this study was to review the clinical features of oromaxillofacial infections in patients presenting to a hospital emergency ward, to identify the key factors affecting the requirement for hospitalization, and the potential risk factors predisposing to a prolonged length of hospital stay. Methods: A retrospective medical record review of the 598 patients treated for oromaxillofacial infection from 2013 to 2017 at the oral and maxillofacial surgery department, Yangsan Pusan National University Hospital, was conducted. The following information was collected from each patient: sex, age, past medical history, site of infection, etiology, admission or outpatient care, level of C-reactive protein (mg/dL), fascial spaces involved, treatment method, and duration of hospitalization. Chi-squared tests were used to identify risk factors, which were further analyzed using multivariable logistic regression. Results: A total of 606 patients were eligible for inclusion in the study, of which eight were excluded due to having incomplete charts; thus, 598 patients were included: 55% were male, mean patient age was 47.1 ± 19.9 years, and 12.9% of patients were diabetic. Furthermore, 71.2% of patients had infection originating in the mandible; the most common tooth of origin was lower posterior, and 29.8% of patients were hospitalized. Risk factors for hospital admission were elderly patients with concurrent disease, elevated C-reactive protein level, and multiple-space infection in the oromaxillofacial area. The duration of hospitalization was correlated with both diabetes and age. Conclusions: The requirement for hospital admission is determined by the severity of the infection; even severe infections, once treated with appropriate surgery, have no relation to the length of hospital stay. The important risk factors for increased duration of hospitalization are diabetes mellitus and older age. The understanding of risk factors associated with a prolonged hospital stay during the treatment of oromaxillofacial infection will aid in treatment planning as well as highlight the importance of adequate diabetes control in patients at risk of such infection.
