Antibacterial Orthodontic Cements and Adhesives: A Possible Solution to Streptococcus mutans Outgrowth Adjacent to Orthodontic Appliances

Varon-Shahar, Einat / Sharon, Esi / Zabrovsky, Asher / Houri-Haddad, Yael / Beyth, NuritPage 49 - 56Purpose: To assess the antibacterial effect of orthodontic cements containing 1% insoluble antibacterial polycat-ionic nanoparticles against Streptococcus mutans.Materials and Methods: Polycationic polyethyleneimine (PEI)-based nanoparticles were incorporated into GC Fuji Ortho LC (GC), CX-plus (Shofu) orthodontic cements and in Neobond Transbond plus (Denstply) and Transbond XT (3M) orthodontic adhesives. The samples were evaluated immediately after setting, as well as after two weeks and one month of aging. The antibacterial effect against S. mutans was evaluated with the direct contact test and the agar diffusion test. In addition, the antibacterial properties of the eluate from the examined materials was tested. Four-way ANOVA followed by Tukey's test was used to determine bacterial growth rates.Results: S. mutans outgrowth was substantially reduced (p
