Active Dentin Caries in Primary Molars

Early childhood caries is a major public health problem affecting preschool children worldwide. Silver Diamine Fluoride is a well-established non-invasive treatment for arresting caries; however, it causes black discoloration of treated lesions. Nano-Silver Fluoride has been introduced as an alternative that may arrest caries without discoloration. This randomized clinical trial aims to compare the efficacy of Silver Diamine Fluoride and Nano-Silver Fluoride in arresting active dentin caries in primary teeth and to assess discoloration, post-operative pain, and parental satisfaction over a 12-month follow-up period.
