Purpose : The study was to promote patient safety by analyzing the effect of dental hygienist's perception of patient safety culture on infection control activities. Methods : The study is based on a survey of 210 dental hygienists in total working in dental settings. To find out infection control activities according to patient safety culture awareness, there were 6 general characteristics, 3 teamwork within the department, 2 infection control systems, 4 surface management, 9 equipment washing, disinfection, and laundry management, 4 infectious wastes, and 3 personal protection phrases.The data was analyzed using the SPSS version 20.0, and p<.05 was adopted to decide on significance. Results : The longer dental hygienists have worked n the dental settings, the more active they become in infection control activities. Among the different types of dental care settings, general (university) hospitals had the largest number of infection control activities, followed by dental clinics, and network dental clinics, in descending order. The dental settings possessing a higher number of dental hygienists were found to conduct more infection control activities than other dental settings. In addition, it was found that when a dental setting adopts a patient safety policy across all the units in the hospital, more systems and procedures for patient safety tend to be established, and that stricter management response to error leads to improvement of infection control activities. Conclusion :In order to enhance infection control activities, infection control activity programs should develop and implement periodic reinforcement of infection control education. regular monitoring of infection control activities.

The stem cell research is emerging as a cutting edge topic for a new treatment for many chronic diseases. Recently, dental stem cell would be possible for regeneration of tooth itself as well as periodontal tissue. However, the study of the cell characterization is scarce. Therefore, we performed the genetic profiling and the characterization of mouse fetus/neonate derived dental tissue and cell to find the identification during dental development. We separated dental arch from mandibles of 14.5 d fetal mice and neonate 0 d under the stereoscope, and isolated dental cells primarily from the tissues. Then, we examined morphology and the gene expression profiles of the primary cells and dental tissues from fetus/neonate and adult with RT-PCR. Primary dental cells showed heterogeneous but the majority was shown as fibroblast-like morphology. The change of population doubling time levels (PDLs) showed that the primary dental cells have growth potential and could be expanded under our culture conditions without reduction of growth rate. Immunocytochemical and flow cytometric analyses were performed to characterize the primary dental cell populations from both of fetus (E14.5) and neonate. Alpha smooth muscle actin (${\alpha}-SMA$), vimentin, and von Willebrand factor showed strong expression, but desmin positive cells were not detected in the primary dental cells. Most of the markers were not uniformly expressed, but found in subsets of cells, indicating that the primary dental cell population is heterogeneous, and characteristics of the populations were changed during culture period. And mesenchymal stem cell markers were highly expressed. Gene expression profile showed Wnt family and its related signaling molecules, growth factors, transcription factors and tooth specific molecules were expressed both fetal and neonatal tissue. The tooth specific genes (enamelin, amelogenin, and DSPP) only expressed in neonate and adult stage. These expression patterns appeared same as primary fetal and neonatal cells. In this study we isolated primary cells from whole mandible of fetal and neonatal mice. And we investigated the characteristics of the primary cells and the profile of gene expressions, which are involved in epithelial-mesenchymal interactions during tooth development. Taken together, the primary dental cells in early passages or fetal and neonatal mandibles could be useful stem cell resources.

Objectives: The purpose of the study is to investigate the effect of values on major satisfaction in dental hygiene students. Methods: The subjects were 214 dental hygiene students in Seoul and Gyeonggi-do who filled out the self-reported questionnaire after receiving informed consents from January 20 to February 15, 2014. Except incomplete answers, 187 data were analyzed using PASW Statistics 18.0 for Scheffe post hoc test, Pearson correlation coefficient, hierarchical regression analysis, independent sample t-test, and one-way ANOVA. The questionnaire consisted of general characteristics of the subjects and values. General characteristics consisted of gender, age, grade, school record, major choice motivation, and the influencing person to choose the major. The instrument for values was modified from Shin based on MILOV(Multi-Item Measures Of Values) and two professors of dental hygiene verified the validity of the instrument. Instrument for values consisted of 7 questions of values for self-respect, 6 questions of relation oriented values, 5 questions of emotion oriented values, and 5 questions of values for others measured by Likert 5 scale. Cronbach's alpha was 0.769 in the study. The instrument for major satisfaction was modified from Na based on Program Evaluation Survey of Illinois University and two professors of dental hygiene verified the validity of the instrument. Major satisfaction consisted of 7 questions of general satisfaction, 5 questions of consciousness satisfaction, 5 questions of curriculum satisfaction and 3 questions of relation satisfaction measured by Likert 5 scale and Cronbach's alpha was 0.887 in the study. Results: Values of self-respect, relationship orientation and grade had significant influence on general satisfaction, while values of self-respect, relationship orientation and gender had significant influence on consciousness satisfaction. Values of relationship orientation, grade and school record had significant influence on curriculum satisfaction. Grade showed significant influence on relationship satisfaction. Conclusions: Values of self-respect and relationship orientation are the most important factors in dental hygiene students. The guidance for professional career and major satisfaction can be accomplished through the values of self-respect and relationship orientation.

Objectives : The purpose of this study was to examine the self-rated oral health concern of adults over the age of 20 and from all over the country and their subjective oral health symptoms in a bid to provide some information on oral health policy setting for adults. Methods : The subjects in this study were 3,558 adults who voluntarily participated in a survey conducted by this researcher at the website of a company. After their answer sheets were analyzed, the following findings were given: Results : 1. 81 percent replied that they were very concerned about oral health. As to the relationship between their general characteristics and oral health concern, there were statistically significant differences in that regard according to their gender, age, purpose of seeing a dentist and occupation. 2. As for the relationship of their general characteristics to subjective awareness of oral health symptoms, there were statistically significant gaps in that aspect according to their gender, age, purpose of seeing a dentist, occupation and state of smoking. 3. In regard to the relationship between oral health concern and subjective awareness of oral health symptoms, those who were more concerned about oral health felt less subjective oral symptoms, but the difference between them and the others was not significant. The respondents who felt more symptoms of dental caries felt more symptoms of periodontal diseases as well. Conclusions : The above-mentioned findings indicate that in order to help adults promote or maintain their oral health, their concern for oral health should be stimulated by providing them with a lot of diverse information, and it seems that the development of programs that can eliminate their subjective oral symptoms of dental caries and peridontal diseases, the primary causes of tooth dysfunction, is required.

Objectives: This study was carried out to provide basic materials to draw up measures for courses operation and effective clinical practice operation for the cultivation of future effective problem solving ability by identifying the relationship between problem solving ability and clinical practice satisfaction of dental hygiene students. Methods: This study targeted 215 dental hygiene students from 3 universities located in Gyeonggi-do from November 30 to December 4, 2015. We analyzed the data with frequency analysis, descriptive statistics, t-test. One-way ANOVA, Pearson correlation coefficient, Regression analysis by using SPSS. Results: Clinical practice satisfaction between grades according to the general characteristics of the study subjects was analyzed and as a result, clinical practice satisfaction showed a significant difference depending on grade (t=-2.355, p=.019), major satisfaction(F=9.548, p=.000), health status(F=4.909, p=.008). The problem solving ability according to the general characteristics of the study subjects was compared and as a result, the problem solving ability score of students 'living apart from their family or living in lodgings' was found to be higher than that of students 'living with their family' (p=.023) and the problem solving ability of students who answered 'satisfied' with their major was higher than that of students who answered 'moderate' (p=.000). As the problem solving ability and major satisfaction are higher and health status is better, clinical practice satisfaction showed higher results (p<.01). Conclusions: The above results showed a correlation between the problem solving ability and clinical practice satisfaction of dental hygiene students and clinical practice satisfaction showed higher scores as the problem solving ability level was higher. Therefore, efforts to enhance dental hygiene students' clinical practice satisfaction are considered necessary by developing and providing a program to strengthen students' problem solving ability.

In the polymeric dental restorative composites, the resin matrix mainly contains 70 wt% 2,2-bis[4-(2-hydroxy-3-methacryloyloxy propoxy) phenyl] propane (Bis-GMA), as a base resin and 30 wt% triethylene glycol dimethacrylate (TEGDMA) as a diluent. Even though the viscosity of the resin matrix is rapidly decreased by adding TEGDMA, addition of TEGDMA to the Bis-GMA results in reduction in the mechanical properties and increase in the curing shrinkage of the dental composite. In order to fabricate dental composite exhibiting excellent properties by reducing TEGDMA content in the resin matrix, in this study, Bis-GMA derivatives, which do not contain hydroxyl groups, were used instead of Bis-GMA. The curing characteristics of Bis-GMA derivatives were similar with those of Bis-GMA, while the former exhibited lower viscosity and water absorption than the latter. Comparing the curing shrinkage of the dental composite containing Bis-GMA derivative with that prepared from Bis-GMA, the reduction in curing shrinkage was about 25%. Dental composites prepared from new resin matrices also exhibited low water uptake and better properties in mechanical strength.

Methods: A self-reported questionnaire was filled out by 389 dental hygiene students in three colleges located in Metropolitan area. The questionnaire consisted of 5 questions of general characteristics, 10 questions of self-efficacy, 18 questions of major satisfaction, and 13 questions of career identity by Likert 5 scale. Cronbach's alpha was 0.92 in self-efficacy, 0.90 in major satisfaction, and 0.88 in career identity in the previous studies. Cronbach's alpha in this study was 0.911 in major satisfaction, 0.840 in self-efficacy, and 0.8090 in career identity. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, and stepwise multiple regressions. Results: The score was 3.47 in self-esteem, 3.79 in major satisfaction, and 3.03 in career identity. There were significant differences in self-esteem and major satisfaction based on grade, motivation for entering college, and clinical practice satisfaction. In case of career identity, there were significant differences based on characteristics, motivation for college choice, and clinical practice satisfaction. There was a positive correlation between negative self-esteem, positive self-esteem, general satisfaction, awareness satisfaction, curricula satisfaction, interpersonal relation satisfaction, and career identity. The influencing factors on career identity were aptitude, interest, self-esteem, and major satisfaction in order(p<0.001). Conclusions: The career identity is closely related to self-esteem and major satisfaction. It is desirable to open a variety of education courses and to develop systematic and practical programs to the students in order to improve the career identity.

This study examined the spirituality of dental hygiene and students and examined whether it affects the stress that may occur during clinical practice. The research tool consisted, clinical practice stresses, and general characteristics. It was held from March to July 2019 for 280 dental hygienists and students in K area. T-test and ANOVA were conducted for differences in spirituality and clinical practice stress according to general characteristics. The correlation between spirituality and clinical stress was analyzed by Pearson corrlation coefficients. As a result, dental hygiene and clinical practice stress of students were negatively correlated with spirituality, major satisfaction, and academic performance. If the motivation to apply to the department was grade, the clinical practice stress was higher. The limitation of this study is that it is impossible to make a concrete comparison because previous studies on the spirituality of dental hygiene and students are insufficient. Therefore, various studies on spirituality and clinical practice stress for dental hygienists are needed, and strategic search will be needed.
