<jats:p>Endodontic shaping can lead to canal and apical anatomical alterations, which may compromise the outcome of root canal treatment. The objective of this systematic literature review is to assess whether the use of martensitic endodontic instruments can result in less apical transportation compared to austenitic instruments during endodontic therapy. A search was conducted on PubMed, Ovid MEDLINE, and the Web of Science. The inclusion criteria were in vitro studies comparing apical transportation using endodontic instruments with austenitic or martensitic alloys. The search of the scientific databases yielded 592 results, of which only 10 were eligible for evaluation after screening. Based on the analysis of the selected articles, it can be concluded that martensitic endodontic instruments result in less apical transportation compared to austenitic instruments during the shaping phase of endodontic treatment. This behavior can be attributed to the increased flexibility of martensitic instruments. Further research is warranted to further explore this topic and provide additional evidence supporting the use of martensitic instruments in clinical practice.</jats:p>
