Visualizing Anatomy in Dental Morphology Education

Tooth morphology is a foundation course for all dental healthcare students including dentists, dental hygiene, dental therapy, and dental nursing students. This chapter explores the conventional and innovative teaching methods to deliver tooth morphology educational modules. The teaching tools are explored with a 2D and 3D lens, with a particular focus on visualization, student understanding, and engagement. Traditional methods of teaching tooth morphology must be complemented with innovative pedagogical approaches in order to maintain student's attention and accommodate their diverse learning methods. Teaching 3D anatomy enables students to visualize and spatially comprehend the link between various anatomical components. Online tests and quizzes motivate students and are also beneficial in preparing students for exams. Online self-examinations offering visualization with 3D teeth enable students to evaluate their knowledge and offers immediate feedback, which aids in the long-term retention of information. These tools can be as efficient as other teaching methods, allowing the students to study at their own pace and with repetition. The authors conclude that blended and innovative teaching methods should supplement student learning and not replace, traditional face-to-face educational methods.

Perception and outcomes after implementation of problem-based learning in predoctoral pediatric dentistry clinical education

PURPOSE

Problem-based learning (PBL) has been a useful addition to health-based curricula by supporting learning with contributory discussion, research, and critical analysis of evidence in a peer-supported learning format. The aim of this study was to determine the impact of PBL on pediatric dentistry clinical education.

METHODS

First-time pass-rates in clinical and objective structured clinical examinations were measured in student cohorts receiving pediatric curricular formats with (PBL+) or without a PBL (PBL-) experience. Student perceived learning outcomes were measured through a voluntary survey. The numbers of each competency attempt were compared between the study groups (PBL+ or PBL-) using Wilcoxon Rank-Sum tests or Fisher's exact tests. Mantel-Hanzel ordinal chi-square tested for differences in rates of agreement on survey responses from students in the PBL+ or PBL- groups. Significance was set at 0.05.

RESULTS

There was a significant improvement in the first-time pass-rates in five of seven competencies in the PBL+ group. A significantly higher proportion of students in the PBL+ group perceived that their predoctoral pediatric dentistry rotation improved their diagnostic skills compared to the students in the PBL- group (p < 0.001). However, there was no significant difference (p > 0.05) between the perceptions on satisfaction of clinical or non-clinical staff support, perceived self-improvement in radiographic or clinical skills or overall benefits of the predoctoral pediatric dentistry rotation.

CONCLUSION

The addition of a PBL component to a traditional curricular format in a pediatric dentistry clinical rotation had a positive impact on learning in a predoctoral dental program.

Male Nurses' Dealing with Tensions and Conflicts with Patients and Physicians: A Theoretically Framed Analysis

Proposes

Delivery of healthcare involves engagements of patients, nurses and other health professionals. The Social Identity Theory (SIT) can provide a lens to investigate intergroup interactions. This study explores how male nurses deal with intergroup tensions and conflicts with patients and physicians when delivering healthcare.

Methods

A collaborative qualitative research study was conducted by two research teams, with one from Mainland China and the other from Macau. Twenty-four male nurses were recruited, with 12 from each of the two regions. A similar guide was used by the two teams to conduct in-depth interviews with the participants. Thematic analysis was used, and SIT guided the data analysis and interpretation of the results.

Results

Four themes identified are related to nurse/patient relationships: respecting patients’ decisions, neglecting minor offenses, defending dignity, taking a dominant position; two themes are related to nurse/physician relationships: rationalizing physicians’ superiority over nurses, establishing relationships with physicians by interpersonal interactions.

Conclusion

Male nurses avoid confrontation with patients in case of disagreements but take on gender- and profession-based dominance in dealing with intense conflicts to maintain healthcare order. They do not challenge the status hierarchy between nurses and physicians but manage to maintain harmonious relationships with physicians by engaging in interpersonal activities with physicians in leisure times.

Implication

Male nurses can take the lead to create inclusive groups to engage patients and physicians in delivering healthcare. The masculine traits of male nurses do not subvert the nurse/physician hierarchy stereotype but strengthen it.

Update on research and application of problem-based learning in medical science education

Problem-based learning (PBL) is a unique form of pedagogy dedicated to developing students' self-learning and clinical practice skills. After several decades of development, although applications vary, PBL has been recognized all over the world and implemented by many medical schools. This review summarizes and updates the application and study of PBL in medical education through the literature published between 1993 and early 2017. It focuses on understanding real medical PBL courses and ways to improve PBL to achieve better learning outcomes. PBL aims to develop lifelong skills to solve practical problems rather than limiting learning to theoretical knowledge. To achieve this goal, strict and reasonable procedures need to be designed and implemented. Rigorous monitoring and timely feedback and evaluation are indispensable to constant improvements and perfecting of the process. © 2017 by The International Union of Biochemistry and Molecular Biology, 46(2):186-194, 2018.

Attitudes Towards Problem-Based Learning of Faculty Members at 12 U.S. Medical and Dental Schools: A Comparative Study

Problem-based learning (PBL) is a teaching method used in medical and dental education to promote students' problem-solving skills. It may also be a viable tool for interprofessional education in which medical and dental students learn together, collaborate, and learn about, from, and with each other. The aim of this study was to compare medical and dental faculty members' attitudes about and perceptions of PBL at 12 U.S. medical and dental schools known to use PBL. In 2015, 111 medical and 132 dental faculty members (combined n=243) from six medical and six dental schools completed a survey containing ten statements and an open comment section. The response rate was 42% of those who received the survey. In the results, the medical faculty participants showed significantly higher enthusiasm for and agreement with PBL benefits than did the dental faculty participants (p˂0.05). The two groups agreed that PBL should be used to supplement conventional teaching (p>0.05). There were no opposite attitudes or contrasts found between the two groups with regards to PBL. The strongest themes expressed by both groups were that PBL should not be used as the sole method of instruction and that students needed a solid foundation in the subject prior to engaging in PBL.
