Characteristics of 2% and 0.2% chlorhexidine solutions in cavitation preparations in dentistry: a review.

Abstract

In analyzing the study of durability in dental restorations, chlorhexidine appears as a broad spectrum antibacterial agent capable of inhibiting the proteolytic activity of some enzymes that can degrade the collagen fibers of the hybrid layer and increase the adhesion capacity In a restoration. This article analyzes the general aspects of chlorhexidine solutions at two different concentrations, observing the benefits or disadvantages they present on the dentin barrel and the possibility that a restoration has better fixation on the dentin. To obtain the material, a search was made based on the literature, using as source the PubMed and Scielo databases. The search descriptors were used: "chlorhexidine", "dentine", "solutions", and related to the terms "cavity preparations", "recurrence decay". The results of the present review show that chlorhexidine substances in the dental field are of great utility and importance because they provide multiple results when applied in restoration processes and tissues adjacent to it. When applying 2% chlorhexidine, it presents Better than 0.2%.
