Among the tools for the assessment of clinical reasoning competency, computer-based testing (CBT) is considered more useful than paper-based testing (PBT), because teachers can control the timing of information given to the examinees. Such timings could possibly affect the thinking process of examinees. However, few studies reported differences of reasoning between the two testing modes. In the present study, we developed an assessment of clinical reasoning and applied it using CBT and PBT to compare the examinees' performance. The participants comprised 60 students in the fifth-year class in 2012 of the School of Dentistry, Faculty of Dentistry, Tokyo Medical and Dental University. The tests comprised 25 problems, each with four questions, totaling 100 questions. The contents of the questions were the same in CBT and PBT. The students were assigned to CBT (Group C, n = 30) and PBT (Group P, n = 30) groups, with an almost equal gender ratio in the groups. The difference between scores was analyzed with a univariate analysis of variance. No significant intergroup differences were found regarding the test duration, total score, and average score of each question. The number of problems with perfect marks was higher in Group P than in Group C (P < 0.05), probably because Group P students could access the information of the previous question (s) within a problem. Thus, the differences of the examinees' performance between the two testing modes were small.","PeriodicalId":76076,"journal":{"name":"Kokubyo Gakkai zasshi.

Although veterinary dentistry is recognized to be essential for animal health, there are few reports on dental treatments of animals and the relationship between veterinarians and dental technicians. The purpose of the present study was to clarify the current situation of dental treatments of animals and to discuss the involvement of dental technicians in veterinary dental treatments and their collaboration with veterinarians.Methods: Anonymous self-administered questionnaires were mailed to 16 university hospitals for animals, 17 animal clinics, and 87 zoological gardens, and handed out to 36 participants at the oral disease seminar organized by Nippon Animal Hospital Association. The questionnaires included questions on veterinary dental treatments, ways to learn veterinary dentistry, and details of prosthodontic treatments.Results: Eighty-two valid responses (51.3%) were obtained. While 93.8% of veterinarians recognized the need for veterinary dental treatments, 67.9% were actually implementing dental treatments. Only 23.5% of veterinarians who conducted dental treatments experienced prosthodontic treatments, and the major prostheses used for treatments were fillings and crowns. Most veterinarians had fewer opportunities to acquire knowledge and skills about dental treatments. In addition, the recognition of dental technicians and their specialties was low among veterinarians.Conclusion: The results suggested that the dental technician, as a member of a multi-disciplinary team, can contribute to animal health by providing prosthetic appliances and should make efforts to enhance awareness of their specialty.","PeriodicalId":76076,"journal":{"name":"Kokubyo Gakkai zasshi.

However, their proliferation and multilineage differentiation potential decreases with aging or increased time in in vitro culture. To determine culture conditions capable of enabling maintenance of MSCs for extended periods of time, human bone marrow-derived MSCs (BM-MSCs) were cultured in growth medium containing various combinations of growth factors and small chemical compounds. Upon reaching confluence, MSCs were subcultured continuously and then tested for differentiation capacity. After screening various growth factors and small chemical compounds, we found a combination capable of maintaining the proliferation potential of BM-MSCs obtained from a 19-year-old donor (young MSCs) up to passage 13 (P13). In contrast, unsupplemented MSCs reached senescence at P10. Total population doublings of control (P10) and supplemented MSCs (P12) were estimated at 20.4 and 42, respectively. Young MSCs cultured with supplements maintained osteogenic, adipogenic and chondrogenic differentiation capacities at P12 as confirmed by expression of lineage-specific differentiation markers. Furthermore, the supplementation of to BM-MSCs obtained from 65- and 79-year-old donors (aged MSCs) also continued to proliferate until P12, and maintained osteogenic and adipogenic differentiation capacity until P7 and P8, respectively, whereas, unsupplemented aged MSCs stopped proliferating at P8. These results indicate that our extended culture conditions maintained the proliferative capacity of young MSCs while retaining their multipotent differentiation potential, and improved both proliferation and differentiation of aged MSCs.","PeriodicalId":76076,"journal":{"name":"Kokubyo Gakkai zasshi.

The problem often occurs after occlusal intervention by dental care. Although various dental treatments (e. g. occlusal adjustment, orthodontic treatment and prosthetic reconstruction) are attempted to solve occlusal dysesthesia, they rarely reach a satisfactory result, neither for patients nor dentists. In Japan, these symptoms are defined by the term \"Occlusal discomfort syndrome\" (ODS). The aim of this study was to investigate the characteristics of ODS with the simple occlusal sensory perceptive and discriminative test. Twenty-one female dental patients with ODS (mean age 55.8 ± 19.2 years) and 21 age- and gender-matched dental patients without ODS (mean age 53.1 ± 16.8 years) participated in the study. Upon grinding occlusal registration foils that were stacked to different thicknesses, participants reported the thicknesses at which they recognized the foils (recognition threshold) and felt discomfort (discomfort threshold). Although there was no significant difference in occlusal recognition thresholds between the two patient groups, the discomfort threshold was significantly smaller in the patients with ODS than in those without ODS. Moreover, the recognition threshold showed an age-dependent increase in patients without ODS, whereas it remained comparable between the younger (< 60 years old) and elderly (60 years old or more) patient subgroups with ODS. These results suggest that occlusal discomfort threshold rather than recognition threshold is an issue in ODS. The foil grinding procedure is a simple and useful method to evaluate occlusal perceptive and discriminative abilities in patients with ODS.","PeriodicalId":76076,"journal":{"name":"Kokubyo Gakkai zasshi.
