    Clinical assessment strategies for competency-based education in prosthetic dentistry
    (John Wiley and Sons Inc, 2024) Khan, Saadika B; Maart, Ronel
    Reflective practice is viewed as a theoretical and pedagogical concept in higher education having several diverse approaches and interpretations. The most important aspect of reflective practice is that it is a necessary quality assurance aspect of higher education which should occur recurrently and at different stages of the program. It usually entails an evaluation of advanced instructions which has become the norm in an educational setting, in order to improve the learning outcomes. Reflective practice must therefore be seen as a tool which allows continuous improvement, modifications, and changes to educational approaches, which include theoretical and clinical assessment strategies. Academics in prosthetic dentistry at a research-led university reflected on their current assessment strategies used in the senior undergraduate dental program as part of a quality assurance process and its global comparability. This paper aims to share and explain the importance of reviewing assessment strategies in higher education, especially in such a clinical program using reflective practice as a framework. Different assessment strategies used over a 5-year period are explored and their different structures, expectations, and appropriateness for a clinical program are reported from the literature. The concerns were addressed in a cyclical manner within this framework, and Blooms and blueprinting implemented where appropriate. We conclude that without a validated definition and framework for regular reflective practices, and guidelines to modify the included assessment strategies, the quality assurance within a competency-based dental program may be compromised.

    Determining the ability of senior dental students to detect interproximal caries using different radiographic techniques
    (John Wiley and Sons Ltd, 2024) Abdalla, Muzan; Khan, Saadika B
    Objective: To evaluate the diagnostic capability of 5th-year students using digital imaging, conventional bitewing (BW) radiographs, and printed film on paper to detect interproximal caries lesions. Methods: A cross-sectional study was conducted with senior dental students. Three different radiographs: digital, BW, and printed films on paper were used; thus, nine radiographs, each with a 2-min viewing time, were considered by students along with a questionnaire. A control group of specialists from Prosthodontics and Radiology had finalized the answers prior to conducting the study. The appropriate responses were divided into five categories: R0: Intact surface, R1: Radiolucency in the outer half of enamel, R2: Radiolucency in the inner half of enamel, R3: Radiolucency in the outer half of dentin, and R4: Radiolucency in the inner half of dentin. Students' responses were analyzed using a one-way analysis of variance (ANOVA) test and a t-test. Results: Ethics for the study was obtained from the institutional committee (Reg No: BM19/9/8). When compared with the control group using ANOVA testing, the results showed good detection accuracy with a success rate of 64 accuracy. There was a significant difference in the outcomes when detecting the presence of the caries lesion between the three diagnostic techniques (p >0.001). In detecting the size of the carious lesion, the students' ability was recorded as poor. The highest average for detecting the presence of the carious lesion was correspondent to the printed film on paper method.

    Translation of the shortened dental arch research into clinical practice: A stakeholder mapping approach
    (Springer Nature, 2020) Khan, Saadika B
    The classic shortened dental arch (SDA) as a prosthodontic concept was originally described by Käyser and comprises of 20 occluding anterior and premolar teeth only.1,2 This SDA treatment option, now also referred to as a posteriorly reduced dental arch (PRDA) due to the different combinations of missing posterior teeth, may be considered as a beneficial treatment approach for developing countries such as South Africa (SA).
