491 - Primary Molars Proximal Silver Diamine Fluoride Application After Elastic Separation

Behavior and medical conditions limit restorative techniques in the pediatric patient population. Silver diamine fluoride (SDF) application has shown high efficacy as a cariostatic agent on smooth surfaces of anterior teeth but has yet to be implemented for treatment for the hard to clean proximal surfaces of posterior teeth. This study investigates if SDF directly applied to proximal, enamel-only caries lesions of primary molars exposed by orthodontic elastic separators is effective in preventing caries progression into dentin. A retrospective chart review on patients 3 to 10 years who received SDF direct application on proximal surfaces of posterior primary teeth using elastic separators at the University of Florida Pediatric Resident Clinic between 2021 and 2023 was performed. Records notes and bitewing radiographs from initial and subsequent recall appointments were evaluated by two independent and calibrated investigators for caries progression. Data analysis by nonparametric methods is ongoing. Upon completion of data analysis, we hope to be able to indicate if this treatment modality is effective in controlling caries progression into dentin of incipient lesions of primary molars.
