Dental clinical evaluation: a review of the research

Preclinical and clinical evaluation in dental education needs systematic study. Research on the main variables affecting reliable and valid clinical evaluation is reviewed to identify research findings applicable to clinical evaluation settings. The research reviewed shows that performance criteria should be objectively stated, that measurement scales should contain few points, and that evaluator training may improve reliability. Suggestions for the design of future evaluation studies are provided in an effort to expand the scope and usefulness of this type of research.
