Staphylococcus species are one of prevalent pathogens found in hospitals. Microbes that are a primary cause of nosocomial infection were isolated from a dental and medical environment it may assist the reader to explain what this is and how it differs from the 'dental health care providers and ward health care providers'. To investigate the distribution of staphylococcus species in this environment, we used vitek II to measure drug sensitivity, and further performed biochemical testing. The isolation rate of staphylococcus species from the dental and medical environment was 100% but from dental health care providers and ward health care providers were 44.4% and 33.3%, respectively. In the analyses, staphylococcus species showed resistance to diffusion of cefoxitin and oxacillin discs. These staphylococci may be sufficiently positive for the mecA gene. Our results suggest that staphylococci might be an important cause of nosocomial infection in the dental clinic.

This research had the following results after analyzing the questionnaires and the survey on 51 people experienced smoking and 51 people unexperienced smoking out of patients who participated in the practice hours of Department of Dental Hygiene to study the relevance between smoking which is one of the partial factors of oral disease and oral health. 1. 78.4% of patients smoke more while drinking, which level is still high, so it threatens the oral health. 2. 22.5 % of patients had the experience of scaling within recent 1 year, which level is still low. 3. The people who experienced smoking realized the harmfulness of smoking and during the toothbrushing, the level of self-consciousness about halitosis and bleeding gum is higher than the unexperienced. 4. The frequency of smokers' toothbrushing on the average a day is lower than non-smokers. 5. Simplified oral hygiene index of men(4.98) is higher than woman(4.00) and the people experienced smoking(4.59) is higher than the unexperienced(4.18), which means that man and the person who experienced smoking has the bad oral environment.

This study was conducted to identify the relationship among the cognitive function of the elderly with dementia in the nursing home and the oral health condition and pathogenic microorganisms in the mouth. Data was collected for a month in February 2019 for 30 people through a non-probable sampling method due to the special nature of dementia elderly people aged 70 years or older, living in nursing homes in Daegu. Technical statistics, ANOVA, and Pearson's correlation coefficient were analyzed using the SPSS window ver. 21.0 program. According to the study, the lower the rating of long - term care classification in nursing homes, the more the number of high-risk oral pathogens, and the more the number of existing permanent teeth, the more the number of microbes in the mouth. However, there was no significant difference in cognitive function. Therefore, it is suggested that oral health care, an elderly dementia people in nursing homes, should have different management methods depending on the oral environment, and also professional managers should be able to manage oral health condition for actual care.

Background: To identify the factors that affect the current status and satisfaction of people with disabilities at community oral care centers. Methods: A structured self-administered survey, including five questions on facility environment, five on usage procedure, four on medical skill, four on care cost, three on friendliness, and three on satisfaction, was administered to 218 residents of the G-disabled community care center. It comprised a Likert 5-point scale (strongly agree, 5 points; agree, 4 points; moderate, 3 points; disagree, 2 points; not at all, 1 point). The reliability of the measurement tool was 0.932 for Cronbach's α. Results: The evaluation of community oral care centers for the disabled showed that the environment was hygienic (4.42±0.73), reservation system was well maintained (4.18±0.95), and the dentist-in-charge was satisfied with the treatment (4.37±0.62). The participants agreed that the details were sufficiently explained (4.29±0.71). However, in terms of medical expenses, the score of "have fully heard the explanation of medical expenses and reductions" was 3.88±0.92. The factors affecting satisfaction were sex, final educational background in the facility environment, usage procedure, and medical skill. Conclusion: To increase the satisfaction of people with disabilities at community oral care centers, it is necessary to establish a facility environment and service according to the patients' need and increase the reduction or exemption benefits between different treatment cost categories. Oral health management policies for the disabled should be developed based on these factors, so that the oral care of vulnerable groups in blind spots can be maintained.

Objectives: Dislocation of the temporomandibular joint may occur for various reasons. Although different invasive methods have been advocated for its treatment, this study highlights the value of non-invasive treatment options even in chronic cases in a resource-poor environment. Materials and Methods: A seven-year retrospective analysis of all patients managed for temporomandibular joint dislocation in our department was undertaken. Patient demographics, risk factors associated with temporomandibular joint dislocation and treatment modalities were retrieved from patient records. Results: In all, 26 patients were managed over a seven-year period. Males accounted for 62% of the patients, and yawning was the most frequent etiological factor. Conservative treatment methods were used successfully in 86.4% of the patients managed. Two (66.7%) of the three patients who needed surgical treatment developed complications, while only one (5.3%) patient who was managed conservatively developed complications. Conclusion: Temporomandibular joint dislocation appears to be associated with male sex, middle age, yawning, and low socio-economic status, although these observed relationships were not statistically significant. Non-invasive methods remain an effective treatment option in this environment in view of the low socio-economic status of the patients affected.

Background: The leaves of Perilla frutescens, commonly called perilla and used for food in Korea, contain components with a variety of biological effects and potential therapeutic applications. The purpose of this study was to identify the components of 70% ethanol extracted Perilla frutescens (EEPF) and determine its inhibitory effects on oral microbial activity and production of nitric oxide (NO) and prostaglandin E2 (PGE2) in lipopolysaccharides (LPS)-stimulated Raw264.7 macrophages, consequently, to confirm the possibility of using EEPF as a functional component for improving the oral environment and preventing inflammation. Methods: One kg of P. frutescens leaves was extracted with 70% ethanol and dried at -70℃. EEPF was analyzed using high-performance liquid chromatography analysis, and antimicrobial activity against oral microorganisms was revealed using the disk diffusion test. Cell viability was elucidated using a methylthiazolydiphenyl-tetrazolium bromide assay, and the effect of EEPF on LPS-induced morphological variation was confirmed through microscopic observation. The effect of EEPF on LPS-induced production of pro-inflammatory mediators, NO and PGE2 was confirmed by the NO assay and PGE2 enzyme-linked immunosorbent assay. Results: The main component of EEPF was rosemarinic acid, and EEPF showed weak anti-bacterial and anti-fungal effects against microorganisms living in the oral cavity. EEPF did not show toxicity to Raw264.7 macrophages and had inhibitory effects on the morphological variations and production of pro-inflammatory mediators, NO and PGE2 in LPS-stimulated Raw264.7 macrophages. Conclusion: EEPF can be used as a functional material for improving the oral environment through the control of oral microorganisms and for modulating inflammation by inhibiting the production of inflammatory mediators.

PURPOSE. The aim of this study was to design an intraoral environment simulator and to assess the accuracy of two intraoral scanners using the simulator. MATERIALS AND METHODS. A box-shaped intraoral environment simulator was designed to simulate two specific intraoral environments. The cast was scanned 10 times by Identica Blue (MEDIT, Seoul, South Korea), TRIOS (3Shape, Copenhagen, Denmark), and CS3500 (Carestream Dental, Georgia, USA) scanners in the two simulated groups. The distances between the left and right canines (D3), first molars (D6), second molars (D7), and the left canine and left second molar (D37) were measured. The distance data were analyzed by the Kruskal-Wallis test. RESULTS. The differences in intraoral environments were not statistically significant (P>.05). Between intraoral scanners, statistically significant differences (P<.05) were revealed by the Kruskal-Wallis test with regard to D3 and D6. CONCLUSION. No difference due to the intraoral environment was revealed. The simulator will contribute to the higher accuracy of intraoral scanners in the future.

Purpose : The purpose of this study was to compare changes of salivary flow rate, salivary buffering capacity, and S. mutans after using a mouthwash containing essential oil or probiotics widely used as oral lactic acid bacteria in the oral environment. Methods : Fifty-three healthy adults aged 20 years or older voluntarily participated in this study after they were informed of the purpose of this study. Subjects were divided into a group treated with probiotics (L. reuteri) and a group treated with mouthwash containing essential oil. To evaluate changes in the oral environment, salivary flow rate, salivary buffering capacity, and S. mutans test were performed at baseline and 4 weeks later. Unstimulated and stimulated salivary flow samples were collected for 5 minutes and results were recorded in ml per minute. Salivary buffering capacity was divided into scores of 1 (low), 2 (moderate) and 3 (high) according to the color of the strip. The amount of S. mutans was classified as scores of 0, 1, 2, and 3 according to the decision table. Data collected in this study were analyzed at the 95 % significance level using the SPSS Version 23.0 program. Results : Both the unstimulated salivary flow rate and the stimulated salivary flow rate increased statistically after the intervention compared to those before intervention in the probiotics group. However, there was no statistically significant difference between the probiotics group and the mouthwash group. Salivary buffering capacity and S. mutans results showed no statistically significant differences between the probiotics group and the mouthwash group either. The salivary buffering capacity and the salivary flow rate showed a positive correlation. Conclusion : To improve the oral environment, such as salivary flow rate and salivary buffering capacity, an optimal product can be selected in consideration of individual preference and cost-effectiveness.
