320 - Effect of SDF on Interproximal Carious Lesions of Varying Depths

Purpose: The purpose of this study was to compare the effectiveness of treatment with 38% silver diamine fluoride in arresting primary molar interproximal carious lesions of varying depths.

Methods: The initial lesion depths were classified into four groups using the International Caries Classification and Management System (ICCMS). Advantage Arrest 38% SDF was applied interproximally for 60 seconds, followed by the application of fluoride varnish. SDF/fluoride varnish was re-applied after 3 months. The effectiveness of the treatment was evaluated by examining the change in the size of the lesion and need for restorative treatment after 6 and 12 months.

Results: A total of 123 interproximal carious lesions from 30 participants were analyzed. While 41.1% lesions progressed in the fluoride (control) group, only 25.7% of lesions progressed in the SDF group. Lesion progression was observed in 27% of the RA 0 SDF group, 38% of the RA 1 SDF group, 18% of the RA 2 SDF group, and 6% of RA 3 SDF group, and 100% of the RB 4 or higher group.

Conclusion: Applying SDF to interproximal lesions within the enamel (RA 1 and RA 2) may not cease lesion progression more effectively than applying SDF to lesions within the outer ⅓ of dentin (RA 3). SDF treatment appears more effective than fluoride varnish alone for interproximal carious lesions in primary teeth.
