Influence of different modes of application of chlorexidine digluconate on bond strength of universal adhesive system to dentin

Abstract

The restorative dentistry evolved a lot in the past years with the improvement of techniques and adhesive materials. However, the dentin substrate adherence is still considered a major challenge.1 The presence of fluids within dentinal tubules, the regional variation of the dentine and the presence of collagen make critical the performance of adhesive procedures in the substrate. These variable are related to failure of the adhesive restorations through the marginal maladaptation and the reduction of the tooth-restoration union.2
