The Use of Nanofibers in Regenerative Endodontic Therapy—A Systematic Review

Abstract

Pulpal pathology in young permanent teeth, caused by dental caries or trauma, can lead to disruption of root formation, leaving the tooth with an uncertain prognosis. Current therapies for such cases present a number of limitations; thus, the aim of this article is to provide an overview on the use of nanofibers in endodontics. The search was conducted on two databases and eight articles met the inclusion criteria for this systematic review. Data on nanofiber production and fiber characteristics were extracted and systematized in tables. Moreover, the ability of novel scaffolds to deliver either drugs or different therapeutic agents without interfering with the products’ characteristics is analyzed from the in vitro and in vivo data. The potential for nanofiber-based scaffolds to induce cellular differentiation and overcome the limitations of classic regenerative endodontic treatment is also discussed.
