Effectiveness of Coatings in Reducing Biofilm adhesion on Archwires: A Systematic Review

Abstract

For evaluating the effectiveness of coatings in reducing biofilm adhesion on archwire, literature search was conducted on PubMed, Medline, Google Scholar, and Science Direct which analysed the anti-adherent property after nano-coating of archwires against uncoated group. Two risk of bias assessment tools were used & the data extracted from each study was then tabulated. Eight studies fulfilled the inclusion criteria. Risk of bias assessment showed a low - moderate risk for most of included studies. Various nanoparticle coatings were analysed for their antimicrobial property. Adequate implementation of each type of coated arch-wire can aid in reducing the bacterial aggregation around the orthodontic attachments & keeping the white spot lesions at bay irrespective of patient compliance. Most of the studies included in this systematic review were assessed fair in risk of bias assessment. Due to presence of Heterogenicity in terms of varied coating methods employed to check the antimicrobial property, a meta- analysis was not possible.
