BACKGROUND: Silver diamine fluoride (SDF) is a nominally invasive agent for caries arrest, but its impact on composite resin bond strength in primary teeth remains unclear.
AIM: To review the effect of different SDF concentrations (12%, 30%, 38%) on the shear bond strength (SBS) of resin composite to primary tooth dentin.
MATERIALS AND METHODS: Forty surgically removed primary teeth were assigned to four groups: Control (no SDF) and three experimental groups (12%, 30%, or 38% SDF). After demineralization and SDF application, the resin composite was bonded to dentin. SBS was quantified with the aid of a universal testing machine, and the data were subjected to statistical evaluation.
RESULTS: The control group showed the highest SBS (10.28 MPa), while SDF-treated groups exhibited significantly lower values (7.36-7.72 MPa). The analysis revealed no statistically significant intergroup disparity among the SDF concentrations (p > 0.05).
CONCLUSION: SDF pretreatment reduces composite resin bond strength to primary dentin, but the concentration (12-38%) does not significantly influence the outcome. Clinicians should consider this when combining SDF with composite restorations.
CLINICAL SIGNIFICANCE: Despite a reduction in bond strength, this study supports the use of SDF because of its therapeutic efficacy in arresting carious lesions in primary teeth, as different concentrations (12-38%) do not significantly affect composite bonding. SDF can be confidently used in minimally invasive pediatric care where long-term caries control is a priority.
