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.

Objectives: The aim of this study was to investigate the education status, knowledge, and perception of oral care among senior nursing students from Republic of Korea who completed all four curricular courses of Introduction to Nursing, Pediatric Nursing, Adult Nursing and Gerontological Nursing in order to provide basic data for effective oral care of inpatients. Methods: A questionnaire survey was conducted for 137 senior nursing students in the Seoul and Gangwon regions who were selected by convenience sampling. The questionnaire consisted of questions about the perception of oral care. A frequency analysis was conducted to analyze education status, perception, and general characteristics of participants. In addition, independent t-test and one-way analysis of variance were conducted to assess differences in the knowledge level according to the characteristics of the students. A p-value less than 0.05 was statistically significant. Results: The study results revealed that 63.5% of the respondents received education on oral care, with 67.8% of them receiving the education during their regular curriculum. Of the responders who said they received education, 41.4% said that education was not enough. Furthermore, the majority of respondents (56.9%) considered dental hygienists to be most suitable for the administration of oral care for inpatients. Conclusion: This study revealed nursing students' positive perceptions of the importance of oral care and dental hygienists'performance of oral care for inpatients. Consideration should be given to healthcare workers in various professions for improving oral health in inpatients, as well as for further study of oral care in the curriculum.

Objectives: The purpose of the study is to investigate the factors influencing on self-esteem, major satisfaction, and career identity. 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.

This study is aimed to establish the direction of orthodontic treatment by analyzing the differences in the dental arch development due to the cause of short stature. Dental diagnostic tests were conducted on patients who were diagnosed with short stature. Idiopathic short statured children were classified through the paired sampling based on the age and gender of a short statured children with growth hormone shortage. Control groups were classified using same method as above, after selecting candidates with an arch length of less than 3mm and malocclusion. In conclusion, short statured children with growth hormone shortage or idiopathic had the higher rate of crowding and the small value of overbite compared to normal children. Therefore orthodontic treatment for short statured children needs treatment plan included evaluation for Arch length discrepancy to treat a crowding early. This study will provide important data for successful orthodontic treatment according to the characteristics of dental occlusion of short statured children.

Purpose: The purpose of this retrospective study was to investigate the relationships of types of dental insurance coverage in Korea with sociodemographic characteristics and the prevalence of systemic and oral diseases, as well as to evaluate the socioeconomic impact of Korean dental insurance policies. Methods: Sample cohort data from 2006 to 2015 were obtained from the National Health Insurance Service. Patients were divided into 2 groups. The exposed group comprised patients who received insurance benefits for complete dentures, removable partial dentures, and implant care, while the control group comprised patients who did not receive these benefits. The type of insurance coverage and the prevalence of systemic and oral diseases were compared between the 2 groups. Results: Patients who received benefits in the form of complete dentures, removable partial dentures, and implants had similar sociodemographic characteristics in terms of sex, age, income quintile, and type of insurance coverage to the control group. The prevalence of hypertension, anemia, renal disease, rheumatoid arthritis, osteoporosis, asthma, and cerebral infarction was higher in the exposed group than in the control group (P<0.05). The prevalence of periodontal diseases and dental caries was also higher in the exposed group. Conclusions: Korean dental health insurance policy has been beneficial for the medical expenses of low-income and elderly people suffering from a cost burden due to systemic diseases. However, since there is a tendency to avoid invasive interventions in older patients due to the high risk of systemic diseases, insurance coverage of dentures may be more helpful from a socioeconomic perspective than coverage of dental implant treatments.

Background: Although the orofacial-function improvement exercise (OFIE; oral exercise) was first introduced in Korea 10 years prior, it is still not covered by medical insurance, and no detailed survey on the dissemination of related programs has been conducted. Therefore, this study investigated the actual status of the education and practice of OFIE among the elderly and at elderly welfare institutions in the Seoul and Gyeonggi Provinces. Methods: Senior citizens aged more than 65 years old, public health centers (total of 69) and elderly welfare institutions (including nursing homes and elderly welfare centers, total of 56) per administrative area in the Seoul and Gyeonggi Provinces were targeted. We analyzed 200 elderly people and 93 institutions who agreed to participate in the survey. For the elderly, general characteristics, experience and route, current practice, and necessity regarding OFIE were investigated. For institutions, the history and plan of education programs on OFIE were investigated. Results: Regardless of the general characteristics, both the rate of experience and practice for OFIE were low overall; moreover, although they felt it was necessary, they had insufficient motivation for its implementation. Moreover, only a few institutions which were operating the education about OFIE regardless of the COVID-19 situation. Conclusion: Although OFIE is necessary for the elderly, its distribution remains insufficient. Therefore, further efforts are needed to expand the education and raise the awareness of oral exercise among elderly individuals and senior welfare institutions.

The purposes of this study were to assess dental fear and anxiety level of patients attending a dental clinic using the dental fear survey (DFS) scale, to apply interventions chosen by patients for reducing dental fear and anxiety and measure their effects. This study surveyed 34 patients who visited a dental clinic in Seoul about their self-rated health and their experience of dental fear, and measured the level of dental fear using DFS. Trained dental hygienists applied interventions desired by the patients for reducing dental fear and anxiety and, for each intervention, examined the patients' satisfaction (very helpful [5 point]~not helpful at all [1 point]). Collected data were analyzed using IBM SPSS Statistics ver. 21.0 through independent t-test or one-way ANOVA for difference in level of fear according to related characteristics, and through Wilcoxon signed rank test for comparison between before and after the intervention. The subjects' mean level of fear (DFS score) was 44.53, which was an average level, and the level of dental fear was relatively high for stimulus-response (2.72). The level of dental fear was higher in those who had experienced pains or indirect dental fear from dental treatment in the past, and those whose subjectively perceived health state was poor (p<0.05). With regard to the applied dental fear intervention, 'Helpful (3.57)' was the most common answer. Overall satisfaction before and after the application of dental fear intervention was generally high as 4.37 and 4.35, respectively, but it decreased slightly after the intervention. In order to lower the level of dental fear, it is considered effective to survey not only the level of dental fear but also patients' need of dental fear interventions and to apply a suitable intervention. It is also required to educate dental workers and to develop related manuals.
