Previous research has shown that accurate student self‐evaluation is related to higher quality dental products. Variance in student performance still remains. Enhancement of visual perception could contribute to product improvement. Only one study has evaluated the effects of magnification on simulated dental patient care. The present study sought to determine if magnification had a positive effect on student‐generated products in pediatric amalgam preparations. Fifty‐two third‐year students were randomly assigned to experimental (magnification) or control (no magnification) groups. Members of the experimental group used magnification in their daily work in the pediatric dentistry clinic. No significant differences between the groups' preparations or evaluations of standard preparations were found. Further study should address these issues: 1) possible effects of specific training in the use of magnification devices; 2) whether the tolerance for error in dental preparations is so great that finer vision contributes little to product improvement; 3) the role of tactile sensation in evaluation and preparation; and 4) the possible benefits of magnification for effect of age. Based on this study, it seems that requiring students to purchase magnification devices may not be justified.
