Basic science courses are extremely important as a foundation for scaffolding knowledge and then applying it in future courses, clinical situations as well as in a professional career. Anatomical sciences, which include tooth morphology, oral histology, oral embryology, and head and neck anatomy form a core part of the preclinical courses in dental technology programs. In this article, the importance and relevance of anatomical sciences to dental personnel with no direct contact with patients (dental technicians) and limited discipline related contact with patients (dental prosthetists) is highlighted. Some light is shed on the role of anatomical sciences in the pedagogical framework and its significance in the educational process and interprofessional learning of dental technicians and prosthetists using oral biology as an example in the dental curriculum. To conclude, anatomical sciences allow dental technicians and prosthetists to a gain a better insight of how tissues function, leading to a better understanding of diagnosis, comprehensive treatment planning and referrals if needed. Patient communication and satisfaction also increases as a result of this deep understanding of oral tissues. Anatomical sciences bridge the gap between basic science, preclinical, and clinical courses, which leads to a holistic approach in patient management. Finally, treatment outcomes are positively affected due to the appreciation of the macro and micro structure of oral tissues.

In dental education, the anatomical sciences, which include gross anatomy, histology, embryology, and neuroanatomy, encompass an important component of the basic science curriculum. At Creighton University School of Dentistry, strength in anatomic science education has been coupled with a solid applicant pool to develop a novel Master of Science in Oral Biology, Anatomic Sciences track degree program. The program provides a heavy emphasis on developing teaching skills in predoctoral students as well as exposure to research processes to encourage the cohort to pursuing a career in academic dentistry. The individuals considered for this program are applicants for admission to the School of Dentistry that have not been accepted into the entering dental class for that year. The students undertake a two year curriculum, studying anatomic sciences with a special emphasis on teaching. The students also must complete a research project that requires a thesis. The students in the program are guaranteed acceptance to dental school upon successful completion of the program. After six years, the first ten students have received their Master of Science degrees and continued in dental school. The program is favorably viewed by the faculty and participating students. It is also considered successful by metrics. Nine of the ten graduates have said they would like to participate in academic dentistry in some capacity during their careers.

Lecture recording system in anatomy     

Thierry R.H. Bacro  Mulugeta Gebregziabher  Jennie Ariail 《Anatomical sciences education》2013,6(6):376-384

The literature reports that using Learning Recording Systems (LRS) is usually well received by students but that the pedagogical value of LRS in academic settings remains somewhat unclear. The primary aim of the current study is to document students' perceptions, actual pattern of usage, and impact of use of LRS on students' grade in a dental gross and neuroanatomy course. Other aims are to determine if students' learning preference correlated with final grades and to see if other factors like gender, age, overall academic score on the Dental Aptitude Test (DAT), lecture levels of difficulty, type of lecture, category of lecture, or teaching faculty could explain the impact, if any, of the use of LRS on the course final grade. No significant correlation was detected between the final grades and the variables studied except for a significant but modest correlation between final grades and the number of times the students accessed the lecture recordings (r=0.33 with P=0.01). Also, after adjusting for gender, age, learning style, and academic DAT, a significant interaction between auditory and average usage time was found for final grade (P=0.03). Students who classified themselves as auditory and who used the LRS on average for fewer than 10 minutes per access, scored an average final grade of 16.43 % higher than the nonauditory students using the LRS for the same amount of time per access. Based on these findings, implications for teaching are discussed and recommendations for use of LRS are proposed. Anat Sci Educ 6: 376–384. © 2013 American Association of Anatomists.  相似文献

殷宏业  刘海侠 《河北工程技术职业学院学报》2007,9(4):71-74

插销法是焊接裂纹敏感性的试验方法。用插销法作为评定低碳钢、低合金钢焊接接头应力腐蚀破裂（Stress Corrosion Cracking，略记为SCC）性能的方法，并以施加于插销的临界初始应力σimpSCC作为评定SCC抗力的指标，用不同型号焊条焊制的20g和16MnR钢，焊接接头HAZ各区及焊缝在沸腾混合硝盐溶液（MNS）中的SCC敏感性的试验结果表明：以插销法的σimpSCC与分别以恒载拉伸法的σSCC和以悬臂弯曲法的J1SCC评定的接头各区SCC抗力的变化规律是一致的，文中还对SCC的亚临界扩展过程进行了讨论。  相似文献
