Comparative Assessment of a New Holistic-Oriented and an Old Specialty-Specific Undergraduate Curriculum in Removable Prosthodontics: A Study Based on Senior Students' Perceptions.

PURPOSE: A survey was conducted in the Dental School, Aristotle University, Thessaloniki, Greece, (i) to assess the perceptions and experiences of senior dental students, Classes of 2014 and 2015, toward the old, specialty-specific (OC) and new, holistic-oriented (NC) undergraduate curriculum, respectively, in removable prosthodontics and (ii) to identify areas of improvement in prosthodontic training. MATERIALS AND METHODS: Structural components of both curricula were collected, including the total number of (i) laboratory/lecture/clinical training hours, (ii) written examinations, (iii) mandatory clinical cases, and (iv) European Credit Transfer and Accumulation System (ECTS) credits. A 20-item closed-type questionnaire using a five-point Likert scale was distributed in two consecutive groups of seniors, Classes of 2014 (n = 54) and 2015 (n = 57); 54 OC and 57 NC senior students filled out the questionnaire. RESULTS: A greater percentage of NC students stated that (i) they felt less confident to carry out jaw relation recording and removable partial denture metal framework design and (ii) the time allocated for clinical training was less sufficient. Students of both curricula reported that the laboratory courses and lectures contributed little to their clinical performance. Implant restorations and prosthetic management of patients with craniomandibular disorders were the most popular treatment options that the respondents felt that should be incorporated in the undergraduate curriculum. CONCLUSIONS: As a general trend, students completing the revised curriculum reported more difficulties during their training and felt more insecure about their clinical competences. To enhance students' self-confidence in prosthodontics, more effective preclinical training methods, introduction of additional treatment options, and alternative educational methods should be considered.

Implementation of a patient-centered approach to clinical dental education: a five-year reflection.

The intent of the redesign of the clinical component of the Harvard School of Dental Medicine (HSDM) curriculum from a traditional numerical procedures-based system to a patient-based comprehensive care system was to improve both patient care and student learning. The aim of this retrospective cohort study was to evaluate the outcomes of and students' perspectives on this patient-centered comprehensive care model introduced in 2009. Data were obtained from the school's Office of Dental Education for a study sample consisting of 205 fourth-year dental students in the graduating classes of 2009 through 2014 at HSDM. The results showed that students were completing more than the required number of comprehensive patient cases on average. A survey given to the Class of 2014 found that the respondents (35 of 36 students) were generally satisfied with the new curriculum and the clinical experience in relation to continuation of care and perceptions of comprehensive care. The results of this study suggest that the redesigned patient-centered assessment model of the clinical component of the curriculum helped improve patient care and student learning.

Communication skills course in an Indian undergraduate dental curriculum: a randomized controlled trial.

This study assessed the impact of a course on communication skills for third-year undergraduate dental students at a dental institute in India. A randomized pretest, posttest controlled trial was conducted with all the students from four cohorts of third-year dental undergraduate students, divided into an intervention group (n=30) and a control group (n=30). The course was developed using Kern's six-step approach to curriculum development. Needs assessment was ascertained, and readings, lectures, and role-plays with real and simulated patients were implemented. Encounters of students during two patient interviews (simulated and real) were rated by two raters using a twenty-seven-item dental consultation communication checklist with a rating scale 0 to 3. Students completed a questionnaire regarding their acceptance of the course. A 2×2 (group × time) ANOVA with group as a between-subjects factor (control vs. experimental) and time as a within-subjects factor (pre vs. post) was performed. The two groups did not differ at pretest but differed significantly at posttest. This study showed that simply attending to patients during a clinical course did not improve professional communication skills. In contrast, the implementation of a course on communication skills did improve the students' dentist-patient interactions. Integrating the teaching and development of a relevant, outcome-based course on communication skills provided clear evidence of communication skills acquisition among these dental students. The course could be introduced in other Indian dental schools.

A critical appraisal of holistic teaching and its effects on dental student learning at University of Bergen, Norway.

The curriculum of the dental faculty at the University of Bergen, Norway, was revised and a new curriculum implemented in 1998 based on the principles of holistic teaching and patient-centered treatment. The first candidates graduated in 2003. The change of curricula, experience gained, and lack of an evidence base for holistic teaching justify a general discussion of all relevant aspects associated with this approach. The purpose of this article was to make a contribution towards such a discussion. A PubMed search regarding holistic teaching in dentistry was performed. Of the 211 entries on holistic teaching, few discussed holism in depth; none reported outcome measures comparing old and new curricula. Data collected from students graduating in 2003 (new curriculum) and 2000 (old curriculum) on their satisfaction with the teaching comprise a possible outcome measure. In most respects, using prosthodontics as an example, no differences between the two groups of students were found. Students studying under the new holistic curriculum were less satisfied than those studying under the old one regarding the number of available teachers and teachers' feedback on student performance. Both holistic teaching/patient-centered treatment and a more traditional subject-specific approach have advantages and disadvantages, and neither can be practiced in its pure form for ethical and practical reasons. The quantitative results of this study did not support the hypothesis that holism improved students' satisfaction with the teaching. A wide discussion of holism in dental education is needed, along with outcome measures when curricula are changed.

Does a case completion curriculum influence dental students' clinical productivity?

The purpose of this study was to evaluate the effects of a new clinical curriculum on dental student productivity as measured by number of procedures performed in the student teaching practice. Harvard School of Dental Medicine adopted a new clinical education model for the predoctoral program in summer 2009 based upon a Case Completion Curriculum (CCC) rather than a discipline-based numeric threshold system. The two study groups (threshold group and case completion group) consisted of students who graduated in 2009 and 2010. Clinical performance was assessed by clinical productivity across five major discipline areas: periodontics, operative dentistry, removable prosthodontics, fixed prosthodontics, and endodontics. The relationships between the two study groups with regard to number of procedures performed by category revealed that the case completion group performed a significantly higher number of operative and removable prosthodontic procedures, but fewer periodontal and endodontic procedures (p≤0.03). No statistically significant difference in number of procedures was observed with fixed prosthodontic procedures between the two groups. Clinical productivity as a result of redesigning the clinical component of the curriculum varied in selected disciplines. The CCC, in which the comprehensive management of the patient was the priority, contributed to achieving a patient-based comprehensive care practice.

Comprehensive dental services for an underserved and medically compromised population provided through a community partnership and service learning.

The University of the Pacific, Arthur A. Dugoni School of Dentistry in San Francisco established a comprehensive dental care program at Laguna Honda Hospital, a public, skilled nursing facility. The program had three goals: (1) to provide dental students and residents an opportunity to provide oral health care for adults who were frail and medically compromised who could not come into the clinics, (2) to increase students' access to patients who needed removable prosthodontics, and (3) to fulfill Pacific's commitment to public service. Laguna Honda and Pacific pooled their resources to bring comprehensive dental care to patients who were not able to access the dental school clinics. The long-term goals are to restore and maintain the oral health of those who reside in the facility, and to educate future dentists to provide oral health care for similar populations.

A comparison of knowledge of local analgesia, pulp therapy and restoration of primary molar teeth amongst dental students, dentists and dental therapists within a dental hospital setting.

AIM: To gain an overview of knowledge of local analgesia, pulpal therapy and restorative procedures in the primary dentition amongst dental undergraduate students (DS), dental therapy students (DTS), recently-qualified dentists (QD) and dental therapists (DT), working within a Dental Hospital setting. STUDY DESIGN: A survey undertaken at Dundee Dental Hospital and School, NHS Tayside, United Kingdom to determine current knowledge regarding the use of local analgesia, pulp anatomy and pulp therapy techniques in addition to restoration of primary teeth. RESULTS: Data were available for 24 individuals (DS: 5; QD: 6; DTS: 8; DT: 5). Deficiencies in knowledge regarding the maximum safe dose for local analgesia, pulp canal anatomy, pulp therapy medicaments and the preparation required prior to placement of a pre-formed metal crown were noted in both student and staff groups. CONCLUSIONS: The knowledge of basic dental procedures for children amongst a group of dental students, student dental therapists and recently qualified dentists and dental therapists, was found to be imperfect. These findings indicate that more research is needed on the educational procedures used in the transfer of such knowledge and skills. Deficiencies in knowledge were identified in all areas assessed. Courses should be designed at both the pre- and postgraduate level to address and avoid such gaps in knowledge.

Interdisciplinary, web-based, self-study, interactive programs in the dental undergraduate program: a pilot.

The goal of this project was to encourage interdisciplinary, integrative health teaching and research in dental education through the development of web-accessible programs, collectively called the "StudyWeb." The specific objective of the project was the construction and integration of a series of prototypes of self-study modules. Four pilot modules were developed using existing teaching materials in histology, pharmacology, prosthodontics, and oral radiology and utilizing a variety of widely available software programs, including FrontPage and Photoshop. Low-end technological choices were made in order to facilitate compatibility with a wide range of hardware, software, and types of Internet access. Modules were tested for functionality, usability, and ease of navigation. The scope of the initial project was limited to development and functionality testing of the original modules. The next phase of this project will involve testing of the effectiveness of these web-based self-instruction tools.

A comparison of student performance in a simulation clinic and a traditional laboratory environment: three-year results.

With simulation clinics, dental schools have improved their preclinical laboratories to provide a more realistic clinical teaching environment. However, there is very little data to support the assumption that these facilities actually improve student performance of technical skills. This study compared the scores of two fixed preparations for full cast crowns by third-year dental students. One of the preparations was made in the simulation clinic manikin, and the other was prepared on the bench top. Three prosthodontic faculty members scored the preparations in the areas of occlusal reduction, axial reduction, resistance and retention, and margination. The study also compared the performance of three classes of dental students: one class with no experience in the simulation clinic, one with one year of experience, and one with two years of experience. The amount of time since completing the fixed prosthodontics course among the students was also evaluated. This was done because the third-year students at the University of Iowa rotate through a series often-week clerkships rather than a comprehensive care model. (Therefore, not all students start clinical prosthodontics at the same time.) In addition, all student participants completed a questionnaire that addressed their perception of their clinical readiness prior to treating their first fixed prosthodontic patient. When we compared the classes of years 1, 2, and 3 by average preparation score, we found a significant difference among the scores for teeth prepared on the bench top (p = 0.0001) but not for the teeth prepared in the mannequin (p = 0.1176). For Year 1 (no simulation clinic experience), the amount of elapsed time following completion of the fixed prosthodontic course was not significant for the tooth prepared on the bench top or in the manikin (p = 0.57113 and 0.0661). For Year 2 (one year of simulation clinic experience), the elapsed time following completion of the fixed prosthodontic course was significant for the tooth prepared on the bench top (p = 0.0482), but it was not significant for the tooth prepared in the manikin (p = 0.2968). For Year 3 (two years of simulation clinic experience), the amount of elapsed time following completion of the fixed prosthodontic course was not significant for the tooth prepared on the bench top or in the manikin (p = 0.7275 and 0.6007). The questionnaire revealed that, in general, the majority of the students perceived their clinical readiness as more than adequate. These results are mixed in that students with more bench top experience scored better on the bench top, and students with more manikin experience scored equally in both environments.

The traditional therapeutic paradigm: complete denture therapy.

The art and science of complete dentures for oral restoration has been espoused and debated for over a century. A tradition of clinical mentoring has passed this prosthodontic trust through time to create an educational cycle where the pupil ultimately became the tutor for yet another pupil. Today's clinical techniques and judgments are an amalgamation of these original prosthodontic philosophies. This article will bring forward some procedures for the fabrication of complete dentures for the scrutiny of their scientific bases. Scrutiny does not imply that aspects of therapy not proved in studies of rigorous scientific design are untruths. However, it is incumbent that those aspects of denture therapy regarded as "public domain" by the corpus of the profession be analyzed. It is also incumbent that possible costly or harmful aspects of denture therapy be identified. There is a paucity of "procedural research" in clinical investigations; research that involves performing an invasive or clinician-intensive procedure. This article also discusses the difficulties in performing procedural research as a means of understanding its importance, but also realizing the reasons that this type of research is not prevalent in the dental and health professional literature. The most common types of investigations used to evaluate patient acceptance and function of dentures will also be discussed.
