Abstract
Preclinical assessment forms an effective strategy in undergraduate training. It enhances the continuous development of skills, facilitates early intervention, and optimizes training resources. Constructive feedback provided to the student fosters continuous improvement in preparedness for professional practice and has implications for the development of a learning culture characterized by student activity. This indeed ensures that a smooth transition will be made toward clinical application of skills. The aim of the study was to evaluate examiner`s reliabilities while applying two different assessment methods: a Glance and Grade assessment method and a Checklist and Criteria assessment method. A total of 100 class I amalgam cavity preparations were assessed by three independent examiners to evaluate Class I amalgam cavity preparations on artificial first mandibular molar teeth prepared by second-year undergraduate dental students in a preclinical laboratory setting. Statistical analysis for inter-examiner and intra-examiner variability was tested using one-way ANOVA test and a paired t-test, respectively. Results of this study showed that intra-examiner variability was significantly reduced with Checklist and Criteria assessment method. The inter-examiner variability was present in a Glance and Grade assessment method while with the Checklist and Criteria assessment method, there was an extremely high level of agreement among the examiners. The study's findings indicated considerable variability among examiners using the Glance and Grade assessment method. However, the Checklist and Criteria assessment method demonstrated remarkable consistency among examiners, indicating that it may offer a more standardized and reliable approach to evaluation.
