The impact of magnification on undergraduate dental students' performance during cavity preparations: A systematic review

Arjun Ramesh et al. J Dent Educ. 2024 Aug.

Abstract

Purpose/objectives: Loupe magnification is a commonly utilized tool within dental education due to its proposed benefits of improving working posture, visual acuity, and procedural quality. Although procedural quality has been researched at the graduate level, literature encompassing the undergraduate level remains scarce. Therefore, this systematic review aims to critically assess the available literature to ascertain the effects of loupe magnification on the performance of undergraduate dental students' cavity preparations.

Materials and methods: A systematic search was conducted across electronic databases, including PubMed, MEDLINE via Ovid, The Cochrane Library for Cochrane Reviews, and Scopus, to identify relevant studies published from inception to February 15, 2023. We included English language studies that evaluated the effect of loupe magnification on the performance of undergraduate dental students in cavity preparations.

Results: In total, six studies fulfilled the inclusion criteria. The outcomes assessed encompassed tooth preparation accuracy. Of these six articles, one was conducted on endodontic access cavity preparations, four on restorative cavity preparations, and one on nonstandard cavity preparation designs performed on acrylic blocs. Four articles determined that loupes positively impacted undergraduate students' performance in cavity preparations, while two articles established no significant difference in performance between loupes and naked-eye cavity preparations.

Conclusion: This systematic review suggests that loupe magnification positively impacts undergraduate dental students' performance in cavity preparations. However, the heterogeneity of the studies and the variations in methodologies limit the ability to draw definitive conclusions.

Keywords: loupes; magnification; systematic review; tooth preparation; undergraduate.
