Abstract

ABSTRACT
Objectives: This study was directed to evaluate the clinical, radiographical, and antibacterial effects of gold and silver nanoparticles as irrigant solutions in primary anterior teeth.
Subjects and methods: 30 kids between the ages of 3 and 5 who had single-rooted primary anterior teeth that needed pulpectomy therapy were chosen. The Nano-Gate helped with the root canal irrigant solutions. A test for antimicrobial activity was assessed. Results: The results of this study revealed that The results of this study revealed that; chlorehexidine CHX and AgNPs irrigant solutions had a significantly higher antimicrobial effect against E. faecalis microorganisms when compared to the tested AuNPs solution. According to the study's clinical and radiographic findings, there was no noticeable difference between the group of teeth irrigated with CHX or AgNPs, but the clinical and radiographic results of this present study revealed that the AuNPs have lower success rates after different follow-up periods when compared with CHX and AgNPs.
Conclusion: Based on the results of this study, The 100 ppm silver nanoparticles and The 100 ppm gold nanoparticles can be used as effective alternative to chlorehexidine irrigant solutions in primary teeth.
