en: The implementation of the Japanese Dental English core curriculum: active learning based on peer-teaching and learning activities.

en: Education in Japan and other Asian countries advocates the stereotypical passive learning style where students are limited in their breadth of knowledge dismissing anything not imparted by their teachers. With globalized education, professions are becoming very competitive, embracing student-centeredness compelling them to introduce active learning activities. A study funded by Japan's Ministry of Education conducted a needs analysis, proposed a solution, and implemented an active learning approach. Since the latter is still new in the Japanese teaching-learning environment, this current study aimed at assessing the willingness of undergraduate students of dental medicine to participate in active learning activities rather than the typical passive-style teaching-learning educational process. Three active implementation-learning activities, namely International Group Discussions (IGD), Student-Teacher Experience (STE) and Role Play Activities (RPA) were included in the Dental English course in a classroom setting at a dental school in Japan. Students had to choose between participating in the activity or taking the final examination. Two hundred and three third-year undergraduate dental students participated over a 5-year period from October 2013 to March 2017. For IGD, the researchers assigned students to a topic and grouped them with visiting international exchange students. For STE, researchers gave students teacher-prepared presentation slides on basic dental topics, which they presented in front of their classmates. For RPA, students had to do prepared role-play and impromptu role play. Peer and teacher feedbacks of the activities were given to all students. At the end of the course, the students evaluated the active learning activities and wrote their comments in a free entry survey. All 203 students participated in the active learning activities confirming the changing learning needs of Japanese students in this dental school. The most common comment was that the class was interesting, fun, an easy-to-understand way to learn dental terms, and a safe way to express themselves in the English language. The majority of Japanese students preferred the active learning style. The study revealed that students reported greater engagement and better learning with proper guidance and time to prepare for the activities.

en: Validity of peer evaluation for team-based learning in a dental school in Japan

en: The aim of this study was to determine the validity of peer evaluation for team-based learning (TBL) classes in dental education in comparison with the term-end examination records and TBL class scores. Examination and TBL class records of 256 third- and fourth-year dental students in six fixed prosthodontics courses from 2013 to 2015 in one dental school in Japan were investigated. Results of the term-end examination during those courses, individual readiness assurance test (IRAT), group readiness assurance test (GRAT), group assignment projects (GAP), and peer evaluation of group members in TBL classes were collected. Significant positive correlations were found between all combinations of peer evaluation, IRAT, and term-end examination. Individual scores also showed a positive correlation with group score (total of GRAT and GAP). From the investigation of the correlations in the six courses, significant positive correlations between peer evaluation and individual score were found in four of the six courses. In this study, peer evaluation seemed to be a valid index for learning performance in TBL classes. To verify the effectiveness of peer evaluation, all students have to realize the significance of scoring the team member's performance. Clear criteria and detailed instruction for appropriate evaluation are also required.

en: Prevalence of prematurely lost primary teeth in 5-10-year-old children in Thamar city, Yemen: A cross-sectional study.

en: The premature loss of primary teeth is a potential risk factor for poor arch length development. Adequate arch length is important to the progression of the permanent teeth. Poor arch length can lead to crowding, ectopic eruption, or impaction of these teeth. This study is designed to assess the prevalence of premature loss of primary teeth in the 5-10-year-old age group. The study group included 185 children, that is, 91 boys and 94 girls. The dental examination was conducted by an experienced examiner under sufficient artificial light. Data including patient age and missing teeth were collected. Descriptive statistics were applied for data analysis, and from the results, Chi-square tests were used at a level of significance of 5% (P < 0.05). We observed a 40.54% prevalence of premature loss of primary teeth with no statistically significant difference between genders. The lower left primary second molar was the most commonly absent tooth in the dental arch (13.5%). The status of premature loss of primary teeth was high in the study group. Implementation of efficient educational and preventive programs to promote oral health would help children maintain a healthy primary dentition and eventually prevent the disturbances in the future development of normal occlusion. Early detection and management of the space problems associated with the early loss of primary teeth would help in reducing malocclusion problems.

en: Effectiveness of a simulated patient training programme based on trainee response accuracy and appropriateness of feedback.

en: Simulated patients (SPs) need education and training in required skills to be effective resources in education. This study was conducted to examine the effectiveness of an SP training programme based on the accuracy of trainee responses and the appropriateness of their feedback. Thirty-two applicants to the training programme and 35 experienced SPs were included in this study. The experienced SPs served as a reference group. The rate of accurate responses and the rate of appropriate feedback were assessed with pre- and post-training tests, and these two outcome measures were compared with those of the experienced SPs. No significant differences were found in trainee response accuracy or appropriateness of feedback between pre- and post-training tests. The response accuracy rate of the trainees on the pre-training test was significantly lower than that of SPs with 1-2 years of experience, whilst there was no significant difference between these SPs and the trainees on the post-training test. Although our study suggests that more training is needed to improve the skills of SPs, the training programme may contribute to helping trainees reach a novice level in the skill of providing accurate responses. SP training should be encouraged to contribute to the effectiveness of such teaching and to establish the validity of the assessment.

en: Study on Evaluation Method of Stress and Recovery : Nasal Skin Temperature and Perception Levels and Psychological States

ja: ストレスおよびその回復の評価法に関する研究 : 鼻部皮膚温度と知覚レベルおよび心理状態

en: In dental treatment of children who are in development of communication ability, the dentists must precisely grasp the psychological state of patients. Although the relationship between nasal skin temperature and psychological state has been reported, their studies experimented only in stress condition. In the recovery stage, the relationships still have not been investigated. Therefore, in this study, we used ice stimulation to subjects' palms as a stressor and tried to clear the relationships between nasal skin temperature and psychological state in the recovery stage from the stress condition. The perception levels and anxiety levels during the experiment period were examined using Time series Visual Analog Scale (T-VAS) and state-trait anxiety inventory-form (STAI) respectively. The nasal skin temperature was measured with thermography every 5 minutes. As a result, when levels of pain and anxiety increased by the ice stimulation, the nasal skin surface temperature decreased. On the other hand, when the pain and anxiety were taken away after the ice stimulation was stopped, the nasal skin temperature increased and reached the same temperature as before the stimulation. These results suggest strongly that the psychological state of pain and anxiety could be predicted by the measurement of nasal skin temperature.

ja: 当外来診療室で行われている手指消毒の効果の評価 : 術者の手にフィットしたゴム手袋装着の必要性

en: For prevention of nosocomical infection, hand disinfection is one of the most important factors. The objective of this study was to assess methods of hand disinfection. As some intresting findings were observed through this study, we would like to report on them in this paper.<BR>Twenty pediatric dentists washed and disinfected their hands under the conditions of not wearing rubber gloves and wearing. After washing the hands in the running water, using a cake of soap, disinfected them with 75% povidone-iodone andscrubbing the paper towel, they pressed then five right fingers on Brain Heart Infuusion agars and the agars were incubated in aerobically atomosphereat 37°C, for 48 h. As results, under the condition of not wearing the rubber gloves, microorganisms could not be eliminated with any methods, but when wearing them some dentists were able to eliminate microorganisms properly by washing in running water. Some dentists who wore larger gloves were not able to eliminate microorganisms using a cake of soap but all of the dentists were able to eliminate them by disinfecting with 75% povidone iodone. Based on these results we must use well fitting rubber gloves and disinfect ourhands.
