Mineral trioxide aggregate (MTA) is widely used in endodontic therapy as a pulp-capping material, root or furcal perforation repair material, and for apexification and obturation of the root canal system. The purpose of this study was to formally document cases of MTA application in South Korean children and adolescents. Through this research, the practice of using MTA will be introduced and familiarized to the clinical practitioners. This study involved endodontic treatment using MTA for fractured crowns in 11- and 12-year-old. The children were followed up for 12 months until the pulp vitality was confirmed; in young permanent teeth with immature roots, the pulp is integral to the process of apexogenesis. These observational results regarding the use of MTA as an apexification material in non-vital immature permanent incisors appear to provide promising results in the search for new materials to meet existing endodontic needs.

The objective of this study was to realize research demands by gathering the research agenda from the Korean Dental Hygienists Association and affiliated groups through a Delphi survey. The study subjects were the heads of eight groups. The Delphi survey was conducted by e-mail after a researcher explained the objective of the study to the heads. The research agenda was classified according to the Korean dental hygiene academic classification and the National Dental Hygiene Research Agenda classification. To compare the number of research agendas according to classification among the groups, we conducted a chi-squared test by using IBM SPSS 20.0. In total, 316 agendas were submitted. According to the Korean dental hygiene academic classification, there was a significant difference among the groups, and the agendas associated with clinical dental hygiene (36.7%) were the best. According to the National Dental Hygiene Research Agenda classification, there was no significant difference and the agendas associated with health promotion and disease prevention (27.8%) were the best. In conclusion, the Korean Dental Hygienists Association and affiliated groups demanded similar research agendas, corresponding to the purpose of each establishment. However, the groups did not seem to show unique characteristics according to the purpose of each establishment. In other words, the groups should corroborate such characteristics and suggest a corresponding agenda to establish specific areas of research in dental hygiene. Also, dental hygiene researchers should mark the academic classification of the studies they want to submit.

The purpose of this study was to investigate life stress and resilience levels, and the relationship between life stress and resilience among dental hygiene students. From July 11, 2016 to July 29, 2016, questionnaires were used to survey dental hygiene students in several areas, after which the data collected from 274 questionnaires were analyzed with IBM SPSS Statistics ver. 21.0 for Windows. The results showed a significant negative correlation between life stress and resilience for dental hygiene students in all factors (p<0.05, p<0.001). This means that higher the resilience, the lower the life stress. Therefore, it is necessary to enhance resilience as a preventive dimension and develop associated program to help dental hygiene students cope with life stress.

This study is conducted to provide a basis for effective management of bad breath with a poll in 155-scaling patients visiting the dental hygiene department of a university located in Gyeong-gi province after grasping the relevance among halitosis, xerostomia, and stress from them. Analysis was performed using PASW Statistics 18.0. The results of the halitosis measurements based on the general properties showed a significant difference in the hydrogen sulfide (H₂S) level depending on the patient's age; the highest level of 355.61 was observed in patients in their twenties followed by 227.85 in the fifties (p<0.001). The level was higher in cases with sinusitis or rhinitis (p=0.034). The H₂S and (CH₃)₂S levels showed are levant (r=0.492, p<0.01) correlation with the components of halitosis. Further, among other factors affecting breath odor, (CH₃)₂S was shown to increase with increased stress. These results indicate that emotional factors, such as stress, should be considered when diagnosing patients with halitosis, and systematic and standardized diagnostic tools should be developed.

With change in the pattern of disease occurrence and increase in the interest in health, efforts to assess the health status on patients covering their subjective awareness at the same time as clinical and objective evaluation on health are continued. To measure health-related quality of life can be one of these efforts. This study was performed to evaluate the relevance of the quality of overall health-related-life and oral health condition. Also the second year (2014) materials in the 6th the National Health and Nutrition Survey were applied to this study. The factors affecting general health related quality of life measured by EuroQol-5 dimension (EQ-5D) have been confirmed by gender, age, education level, income level, private health insurance, perceived health status, toothache experience during the last 1 year, remaining tooth number. As oral health plays an important role in determining the overall health conditions, objective oral health state influences the whole body health. Hence, it can be regarded that oral health is ultimately related to the general health-related quality of life.

The purpose of this study was to evaluate the efficacy of the newly-developed Qraypen™ (All In One Bio, Korea) system for the diagnosis of early proximal caries by comparing it with the conventional methods of visual inspection and periapical radiography. This study was carried out from July 2015 to April 2016 targeting 32 children aged 7~12 years who visited Y-Dental Clinic for school oral health examinations. Two investigators selected and examined a total of 153 primary molars that had not undergone restorative treatment. Comparisons were carried out between visual inspections, readings of posterior periapical radiography images, and readings of Qraypen™ images. This study revealed that the percentage of interproximal surfaces of primary molar teeth without caries incidence was 83.7% using Qraypen™ imaging and 84.9% using visual inspection and periapical radiography. The differences between the two methods were not statistically significant. Thus, Qraypen™ is expected to be a useful and convenient auxiliary diagnostic device that can facilitate the detection of hidden proximal caries in primary molars.

This study sought to examine the factors influencing clinical competence of dental hygienists. A survey on burnout, critical thinking tendency, self-esteem, self-leadership, professional self-concept and clinical competence was conducted with 254 dental hygienists using self-administered questionnaires. Correlation analysis was performed between study variables, and linear regression analysis identified factors influencing clinical competence. To determine a causal relationship among these factors, a path analysis was conducted at the 0.05 level of significance. Relationships among research variables showed significant positive correlations (p<0.01). Self-esteem, self-leadership, and professional self-concept were found to influence clinical competence (p<0.01). A causal relationship was also found among variables influencing clinical competence. Burnout and critical thinking had an indirect effect, whereas self-esteem, professional self-concept, and self-leadership had both direct and indirect effects. In conclusion, important factors influencing clinical competence of dental hygienists include self-esteem, self-leadership, and professional self-concept. Based on these findings, programs to enhance clinical competence of dental hygienists should be developed.

This study aimed to investigate the effect of repeated oral health education on the oral health of preschool children. This study classified the control group of children of 5~6 years of age where the oral health education was conducted one time, and the experiment group where the oral health education was conducted 4 times. The oral health conditions of each group and their risk of developing dental caries were also assessed. No significant difference was observed in the participants in terms of general characteristics, oral health conditions, risk of developing dental caries, and oral health behavior after oral health education. The two groups did not show a significant difference (p<0.001) in dental plaque index before and after oral health education, and showed a significant difference (p<0.001) according to the number of education sessions. Before oral health education, the participants in both groups were brushing their teeth incorrectly. However, after the third session, 56.7% of the participants in the experimental group and 9.4% in the control group used the correct method of tooth brushing. A significant difference was observed between the two groups (p<0.05). In addition, when the tooth-brushing time was compared, the two groups showed a significant difference (p<0.001), and a significant difference was observed in terms of the number of education sessions (p<0.05). In summary, repeated oral health education had significant influences on the dental plaque index, tooth-brushing method, brushing occlusal surfaces, and tooth-brushing time. Therefore, when oral health education is carried out, repeated oral health education in children is more effective than one-time oral health education as reflected in the changes in dental plaque index and oral health behavior. Moreover, oral health education is considered effective in changing the oral health behavior of children when conducted at least 3 times.

We attempted to develop a problem-based learning (PBL) module for integrated education in dental hygiene with the aim of helping students gain clinical competencies necessary for dental hygienist work. To develop the PBL Module for Clinical Dentistry in Dental Hygiene course, the researchers identified literature related to not only educational technology, but also medical science, nursing, dentistry, and dental hygiene. During the design phase of the PBL module, problem scenarios and a plan for the teaching and learning process were developed. Developing problem scenarios involved describing a problematic situation and three questions related with that situation. To cultivate competencies required in dental clinics, each question was related to the diagnosis of a dental disease, dental treatment, and dental hygiene procedures for care. Teaching-learning process plan included the designs of operating environment, operational strategies, learning resources, facilitation of problem-solving process, and evaluation. It is necessary to evaluate the PBL module for integrated education in dental hygiene to confirm its effectiveness.

The present study aimed to examine the influence of mental health factors on oral health factors using data from the Korean National Health and Nutrition Examination Survey (KNHANES). A total of 1,548 elderly individuals aged over 65 years who completed the screening and health questionnaire were selected as the final study participants. The psychological health factors related to perceived oral health status were depression and stress when the gender was controlled, and in terms of gender, both elderly male and female individuals were stressed and depressed. These results suggested that the psychological health of elderly individuals negatively affects not only perceived oral health but also the quality of life. In addition, the psychological health of the elderly individuals should be systematically managed along with oral health care and overall health care and lifestyle. If a comprehensive health management system is available for low-income groups or an elderly person living alone, it should positively affect and improve the quality of life of elderly individuals.
