Comparative analysis of microorganism adhesion on coated, partially coated, and uncoated orthodontic archwires: A prospective clinical study

Influence of Aesthetic Archwire Coatings on Bacterial Adhesion

“…During the analysis of the collected material, two articles on aesthetic archwires were rejected [12,13], because their authors did not provide precise information about the material with which the orthodontic archwires were coated in their study. Finally, in this review, seven articles were included: three in vivo studies (including two randomized clinical trials [14,15] and one controlled clinical trial [16]) and four in vitro studies [17][18][19][20].…”

“…The results of the RoB assessment according to the JBI critical appraisal tool: checklist for randomized clinical trials shows Table 1. In terms of in vivo studies, the review authors assessed that the articles by Costa Lima et al [14] and Hasipek et al [15] had similar risks of bias. The most important difference was found in blinding.…”

“…In vivo studies by Costa Lima et al [14] and in vitro studies by Oliveira et [17], Asiry et al [18] and Kim et al [19] addressed the rhodium coating of orthodontic archwires. Those studies were performed only on aesthetic NiTi archwires.…”

“…As is the case for epoxy resin coating, the results proved to be inconclusive. A randomized clinical trial by Costa Lima et al [14] indicates that rhodium coating increases bacterial adhesion. That study had a slightly higher degree of certainty (low certainty) compared to other articles that examined rhodium-coated archwires (very low certainty).…”

“…The influence of teflon coating was addressed in an in vivo study by Costa Lima et al [14] and in vitro studies by Oliveira et al [17], Asiry et al [18], and Al-Sheakli et al [20].…”
