The role of cold atmospheric plasma (CAP) in the control of biofilms on titanium surfaces: A Literature review

Abstract

Aim: Cold atmospheric plasma (CAP) is frequently used for the sterilization of biomaterials in the field of dentistry. The aim of this narrative review is to present the role of CAP in the control of biofilms on titanium surfaces. Materials and Methods: The PubMed, Scopus, and WOS databases were searched to identify scientific articles published between 2010 and 2020, with the keywords 'biofilm,' 'cold atmospheric temperature,' and 'titanium,' using the logical operators AND and OR. Results: We found 8 articles in PubMed, 11 in Scopus, and 10 in WOS, including review articles and original studies, among others. All the articles were selected by two independent reviewers according to the eligibility criteria. Conclusions: Despite the restrictions of this review, CAP seems to have an effect on titanium surfaces in the oral area. Studies have shown that bacterial biofilms become inactive after 3 min of plasma treatment.
