Since the discovery of chlorhexidine as a potential surface antiseptic in the fifties, it has been abundantly used in different kinds of dental pharmaceutics. During the past decade chlorhexidine containing varnishes have been added to this list. These products present several advantages in comparison to the existing chlorhexidine formulations. Varnishes should be considered as further options for prevention of fissure and approximal caries, possibly in combination with already established methods. For patients at high risk for root surface caries, varnish application might be a meaningful preventive and therapeutic approach. In this paper, the existing literature on the use of two different chlorhexidine varnishes (Cervitec and EC40) in different fields in dentistry will be reviewed.

Background: A high level of scientific evidence supports several nonrestorative strategies for the control of caries, with the goal of reducing progression of mineral loss and arresting existing lesions. The authors provide an overview of evidence for nonrestorative caries control and considerations in the decision making for selecting nonrestorative options.
Types Of Studies Reviewed: The authors discuss findings from existing reviews, systematic reviews, and evidence-based guidelines (particularly from the American Dental Association) describing the effectiveness of nonrestorative strategies available in the US market for remineralization and arrest of caries lesions.

Background And Purpose: The aim of this study was to evaluate the physico-mechanical, anti-bacterial, and anti-demineralization properties of orthodontic resin composite containing photoactivated zinc oxide nanoparticles (ZnONPs) on Streptococcus mutans biofilm around ceramic and metal brackets.
Material And Methods: Following the minimum inhibitory concentration (MIC) determination for ZnONPs, shear bond strength (SBS) was tested for composites containing different concentrations of ZnONPs. The chosen concentration was used to evaluate the microleakage, anti-bacterial, and anti-demineralization properties.

Aim: The purpose of the present study is to evaluate the effect of nanosilver fluoride (NSF), chlorhexidine (CHX), and sodium fluoride (NaF) when used as a varnish on levels in children with dental caries.
Study Design: A total of 120 children (age range 8-12 years) with incipient caries were randomly assigned to four groups ( = 30): group I-NSF varnish, group II-CHX varnish, group III-NaF varnish, and group IV-control. Varnish application at baseline was performed once.

Aim: Testing the effect of Fluoride, chlorhexidine, and molecular iodine applications on the mean micro-shear bond strength (SBS) of enamel in an attempt to preserve enamel integrity during the bonding process.
Materials And Methods: The study was an observational case-control one in which 150 human teeth were classified into 10 groups according to the product kind and the prescribed treatment. Each group consisted of 15 teeth.
