In vitro antibacterial activity of self-etch bio-active dental adhesives after artificial aging

Abstract

PurposeThe aims to evaluate the antibacterial effect of different bioactive componentcontaining dental adhesives before and after artificial aging.Materials and MethodsTwo bio-active adhesives; Clearfil Protect Bond and FL Bond II, two non-bioactiveadhesives, Clearfil SE Bond and Clearfil S3 Bond were used for this study.Antibacterial activities of the fresh and aged samples against Streptococcus mutanswere investigated with Direct Contact Test. Data were analyzed with Kruskal Wallisand Mann Whitney U multiple comparison tests.ResultsFor fresh samples FL Bond II and Clearfil Protect Bond exhibit similar antibacterialeffect but Clearfil Protect Bond showed significantly higher antibacterial effect afteraging the samples (p < 0.05).ConclusionsThe incorporation of bio-active antibacterial components into adhesive systemsmay be considered as a fundamental component in inhibiting residual Streptococcusmutans when considering the antibacterial effect of fresh samples of bio-activeadhesives.
