Abstract

Background Dental caries is one of the most prevalent diseases, and treating carious lesions remains a major concern, especially in pediatric dentistry. Minimally invasive interventions have been proposed as a promising treatment modality for caries control. Aim This study evaluated nano silver fluoride versus silver diamine fluoride with potassium iodide for the treatment of carious dentine in primary teeth. Material and methods This in vivo study was performed on 30 children presented with 60 primary molars with soft dentinal lesions. Carious teeth were assigned into two equal groups: group I received silver diamine fluoride with potassium iodide, while group II received nano silver fluoride. Teeth were diagnosed and treated at the baseline visit and followed up for clinical evaluation at 3, 6, and 9 months. Also, dentine samples were obtained from the initial carious teeth and after 9 months of applying the treatments for microbiological evaluation. Results Both groups had comparable clinical values at 3, 6, and 9 months, with no statistically significant difference. While after 9 months, there was a highly significant increase in the number of teeth showing dentine color change in group I compared with group II. Microbiological results showed no significant difference in the reduction of Lactobacillus count between both groups. While there was a significant difference between both groups in terms of Streptococcus mutans count. Conclusion Silver diamine fluoride with potassium iodide and nano silver fluoride provides simple and effective dentinal caries management.
