Objective: To compare the caries preventive effects of 2-year application of school-based chlorhexidine varnish, sodium fluoride gel, and dental health education programs among a high-risk group of 11- to 13-year-olds with low caries activity.
Method And Materials: A total of 149 subjects who had previous caries experience in the primary dentition and Streptococcus mutans levels higher than 10(5) at baseline with 0 DMFS index were selected for this randomized clinical trial. Subjects were allocated to one of 3 groups for treatment with chlorhexidine varnish (n = 50), sodium fluoride gel (n = 50), or a dental health education program (n = 49), which were repeated throughout the 2-year study. The outcomes examined at the end of the study were the caries increment (DMFS index), dental plaque scores, and salivary S mutans counts.
Results: The subjects in the education group showed a significant increase in the salivary levels of S mutans in comparison with the other groups (P = .004), but there was no significant difference among the groups in the caries increment after 2 years, with mean DMFS +/- SD as 0.95 +/- 1.33, 0.88 +/- 1.47, and 1.05 +/- 2.01 in the chlorhexidine varnish, sodium fluoride gel, and education groups, respectively. There were also no significant differences in the pre- and posttreatment plaque scores between the groups.
Conclusion: Although all 3 preventive programs in this high-caries-risk group of children with low caries activity resulted in similar plaque and caries values after 2 years, longer follow-up studies are needed to clarify the effect of reduction in S mutans growth by chemotherapeutic agents in caries incidence.

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.
