Value of including loupes in prosthodontic and endodontic components of dental degrees: a systematic review

Abstract

Background It is crucial dental students graduate with sound knowledge of endodontics and prosthodontics. The use of loupes is important for these due to their intricate nature, but there is currently no standardisation of curricula. Objective This systematic review investigates the value of including loupes in completing dental degrees and their benefits to dental students. Methods Literature was searched from inception to February 2022 in PubMed, Embase and Scopus. Articles included were primary studies of dental students studying endodontics or prosthodontics, which had outcomes related to the value of utilising loupes in learning, clinical application and ergonomics. Results A total of 1,489 articles were retrieved, of which 14 relevant articles were identified. These articles discussed student perceptions and the impact on visual acuity, ergonomic practices and dental procedures. Overall, students perceived that loupes increased self-confidence and allowed a greater operative view but were initially difficult to use. Using loupes resulted in greater visual acuity than no magnification and improved ergonomic practices by reducing neck angulation and improving posture. Students also received better grades when using loupes during cavity access preparation or root canal therapy. Conclusion The use of loupes by dental students can be beneficial if there is initial teaching on their use.
