General dental practitioners' perceptions of removable prosthodontics in the undergraduate curriculum

The undergraduate dental curriculum is undergoing rapid change and revision in dental schools worldwide. Decreasing edentulism, the advent of the clinical dental technician, and advances in technology (such as dental implantology) have led to changes in patient management and treatment options for general dental practitioners in New Zealand. The current undergraduate removable prosthodontic curriculum has seen very little change in past years at the School of Dentistry, University of Otago, and is under review to facilitate the teaching of general dental practice in the Final Year. A questionnaire-based survey of 150 general dental practitioners (response rate 74.6 percent) supported modification of the existing removable prosthodontics curriculum to improve its relevance to modern general dental practice. Integration of fixed and removable prosthodontic teaching was recommended.

Dental students' perceptions on the contribution and impact role of a clinical teacher

Objectives

This study was conducted in University of Malaya to evaluate student perceptions on the contribution and role of an effective clinical teacher based on the cognitive apprenticeship model in clinical practice.

Methods

Self‐administered questionnaires were distributed to 233 undergraduate dental students involved with clinical teaching. This modified and validated questionnaire focusing on students' learning environment was used in order to gain relevant information related to dental clinical teaching. Six domains with different criteria applicable to clinical teaching in dentistry were selected consisting of modelling (four criteria), coaching (four criteria), scaffolding (four criteria), articulation (four criteria), reflection (two criteria) and general learning environment (six criteria). Data analyses were performed using IBM SPSS Statistics 20.

Results

Majority of the students expressed positive perceptions on their clinical learning experience towards the clinical teachers in the Faculty of Dentistry, University of Malaya, in all criteria of the domains. Few negative feedbacks concerning the general learning environment were reported.

Conclusion

Further improvement in the delivery of clinical teaching preferably by using wide variety of teaching–learning activities can be taken into account through students' feedback on their learning experience.     

Prosthodontics in a general practice program of advanced dental education.

The problems involved in teaching prosthodontics in a general practice program outwardly appear to be due to the lack of sufficient basic prosthodontic training dispensed by the dental schools. This lack of sufficient training is not the fault of dental school faculties. The students are not learning what they are taught. What they need is more repetition, which means more time. The problems are not insurmountable. We just must find the route.     

The Dental Student as Technician: An 18-Year Follow-Up of Clinical Laboratory Programs

In 1977, a survey of American and Canadian dental schools was conducted by Weintraub to determine the delegation of laboratory procedures in preclinical and clinical complete and removable partial denture programs. This was performed in light of challenges raised to the value of requiring dental students, rather than laboratory technicians, to perform the various laboratory procedures involved in the fabrication of complete and removable partial dentures. Since 1977, the rate of edentulism has declined in the United States, and fewer edentulous patients have sought regular dental care. In addition, approximately 20% fewer curriculum hours have been spent in dental schools in removable prosthodontic instruction; a declining number of graduating dental students have felt comfortable with their level of knowledge of removable prosthodontics, especially complete dentures, and have performed fewer removable prosthodontic procedures in practice because of a perceived lack of treatment cost-effectiveness. The present study, an 18-year follow-up to the 1977 survey, was designed to determine if such trends toward a deemphasis on removable prosthodontic treatment have affected the mechanisms of instruction in and the extent to which dental schools instruct students about removable-prosthodontics laboratory procedures. The 1995 survey was mailed to 53 American dental schools. Forty-six schools returned the completed survey, for a response rate of 87%. Results showed that the relative amount of material presented to students in clinical removable prosthodontics programs increased, primarily through the enhancement of laboratory technician support, both in-house and commercial, of student clinical removable prosthodontic laboratory procedures. The increase was greater than in preclinical removable prosthodontic programs, which were described in a companion article. The conflict between these outcomes and the call by the dental community, as well as that of the 1995 Institute of Medicine Study, for a reduced emphasis on teaching students about the technical details involved in removable prosthesis fabrication is recognized and explored.
