Efficacy of Silver Diamine Fluoride Versus Nano-Silver Fluoride in Arresting Active Dentin Caries in Primary Teeth in Young Children
A study testing Nano-Silver Fluoride and Silver Diamine Fluoride in people with Early Childhood Caries (ECC) and Active Dentin Caries in Primary Molars, run by October University for Modern Sciences and Arts at 1 site in Egypt.
Trial summary
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. Read more about this study

About this study
Official title: Efficacy of Silver Diamine Fluoride Versus Nano-Silver Fluoride in Arresting Active Dentin Caries in Primary Teeth in Young Children: A Randomized Clinical Trial
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.
Read the detailed description
This randomized clinical trial will be conducted on 30 children aged 3-5 years attending the outpatient clinic of Pediatric Dentistry, Faculty of Dentistry, Suez Canal University. Children with active dentin caries in primary molars will be randomly allocated into two groups: Silver Diamine Fluoride group and Nano-Silver Fluoride group.
Both materials will be applied topically without caries excavation. Clinical evaluation will be performed at baseline and at 1, 3, 6, 9, and 12 months using ICDAS criteria, visual and tactile examination, assessment of post-operative pain, discoloration through standardized photographs, and parental satisfaction questionnaires.
The primary outcome is caries arrest. Secondary outcomes include discoloration, pain, and parental satisfaction.

Caries arrest of active dentin caries
Arrest of caries assessed clinically by hardness of dentin using blunt periodontal probe and ICDAS criteria
Measured: 1, 3, 6, 9 and 12 months
Secondary outcomes (3)
Discoloration of carious lesions
Assessment of color change using standardized pre- and post-operative photographs
Measured: 1, 3, 6, 9 and 12 months
