Cariostatic and Remineralizing Effects of Three Different Dental Varnishes

Dental Caries in Children Clinical Trial

Official title: Cariostatic and Remineralizing Effects of Three Different Dental Varnishes (A Clinical Trial)

Status Completed

Clinical Trial Summary

This study is a randomly, controlled, prospective in vivo study.

The objective of this study is:

To evaluate the cariostatic and re-mineralizing effects of Nano silver fluoride, Nano Hydroxyapatite and sodium fluoride varnishes in caries prevention through:

1. Clinical evaluation using international caries detection and assessment system (ICDAS II visual scoring criteria)

2. Calcium and fluoride content using enamel biopsy

Clinical Trial Description

Dental caries is a chronic, multi factorial, transmissible, infectious disease. Caries prevalence in young children in Egypt is very high, and most of the decayed teeth are left untreated, The increase prevalence of dental caries in children globally and in developing countries such as Egypt particularly makes the need for preventive treatment is necessary, one of the ways to prevent dental caries is the application of fluoride which can prevent dental caries by inhibiting demineralization of the crystal structures inside the tooth and enhancing remineralization.

Subsequently over the years various topical fluoride agents have been evolved but NaF (a 22,600 ppm F- preparation) is the most commonly used agent, Based on systematic studies, 5% NaF varnish was more effective in re-mineralizing early enamel caries.

Another anti caries product is a nano-hydroxyapatite (n-HAP), it has antibacterial effect, higher solubility, surface energy and bio activity, there are several studies concluded that 10% (n-HAP) may be optimal for remineralization of early enamel caries Nano-Silver Fluoride (NSF) is a new experimental formulation containing silver nanoparticles, it was introduced by Targino AG et al.(2014) to combat the problem of black discoloration of Silver Diamine Fluoride. It is safe to be used in humans and has effective antimicrobial properties against the pathogens responsible for the development of dental caries.

most of the studies have been evaluated the effectiveness of anti-caries agent in In Vitro and to the best of our knowledge, there are no published studies in Egypt on the effectiveness of these agent. As such, due to the continuous development of new remineralizing agents, research is needed to investigate the newer remineralizing agents under different circumstances. The present study will be carried out to evaluate the efficacy of Nano silver fluoride, Nano Hydroxyapatite and Sodium fluoride varnishes in caries prevention. ;
