RODRIGUES, Roberta Bento et al. In vitro evaluation of the antibacterial behavior of a self-etch adhesive associated with chlorhexidine. Rev. odontol. UNESP [online]. 2019, vol.48, e20170094.  Epub 25-Mar-2019. ISSN 1807-2577.  https://doi.org/10.1590/1807-2577.09417.

Introduction

Adhesive technology has been developed quickly since its introduction about fifty years ago. Its goal is to produce a close contact within enamel and dentin. Failures in this process could result in microleakage, and allow the infiltration of bacteria, fluids and ions. Recent studies have been shown the use of chlorhexidine associated with adhesive systems can be able to inhibit the bacteria action.

Objective

The aim of this study was to evaluate the addiction of different percentages of chlorhexidine to a self-etch adhesive.

Methodology

The solution of digluconatechlorhexidine was increased to the primer of the two pass self etch adhesive to create a 0.5%, 1.0% and 2.0% chlorhexidine primer solution and after they were distributed in four groups (G1, G2, G3 and G4). Saliva samples (N=10) were used to test bacteria activity.

Result

They were spread in a blood medium with filter paper disks containing the different treatments. After the incubation, the inhibitions halos formation were evaluated.

Conclusion

This study demonstrated that, in vitro, the addition of different percentages of chlorhexidine digluconate to the self-etch adhesive induced inhibited halos at bacteria of saliva samples, independent from their concentration.
