Silver Nanoparticle vs Chlorhexidine Mouthwashes for Reducing Streptococcus Mutans and Improving Salivary pH in Children

Dental caries remains one of the most common chronic diseases in children, with Streptococcus mutans playing a major role in its development. Chlorhexidine mouthwash is an effective antimicrobial agent but its use in pediatric patients is limited by adverse effects such as tooth staining, taste alteration, and mucosal irritation. Silver nanoparticle (AgNP) mouthwash has emerged as a potential alternative with broad-spectrum antimicrobial activity and a potentially improved safety profile. This randomized, double-blind, parallel-group clinical trial will compare the efficacy of 10 ppm silver nanoparticle mouthwash with 0.2% chlorhexidine mouthwash in reducing salivary Streptococcus mutans levels in children aged 6-12 years at high caries risk.

Dry-Shield vs Rubber Dam During Fissure Sealant Placement

This randomized clinical trial aims to evaluate the efficiency of the Dry-Shield isolation system compared with rubber dam isolation and cotton roll isolation during fissure sealant application in permanent molars among pediatric patients. The study evaluates chairside time, patient preference, and fissure sealant retention rates after 6 and 12 months of follow-up. Proper isolation during fissure sealant application is considered essential for optimal retention and long-term clinical success. The study also aims to assess whether Dry-Shield can provide a practical and comfortable alternative to conventional isolation techniques in pediatric dentistry.
