Abstract

Objectives: This study aimed to evaluate the effect of silver diamine fluoride (SDF) pretreatment on the micro-shear bond strength (μSBS) and failure mode of two bioactive restorative materials—giomer (Beautifil Flow Plus) and self-adhesive resin composite (Surefil One)—when bonded to demineralized dentin of primary teeth.
Materials and Methods: Thirty extracted primary molars were sectioned into mesial and distal halves and prepared to expose dentin. Artificial demineralization was performed on two-thirds of specimens. Specimens were assigned to six groups based on dentin condition (sound or demineralized), surface pretreatment (with or without 38% SDF), and restorative material used (Beautifil Flow Plus or Surefil One). μSBS was measured using a universal testing machine. Failure modes were analyzed under a stereomicroscope. Statistical analysis was performed using the Kruskal–Wallis H test, with significance set at p ≤ 0.05.
Results: SDF application caused a non-significant reduction in Beautifil Flow Plus bond strength (p = 0.402) but significantly increased the μSBS of Surefil One (p < 0.001).
Conclusion: SDF pretreatment had no significant adverse effect on the bond strength of Beautifil Flow Plus to demineralized dentin but significantly enhanced the bond strength of Surefil One. These findings suggest that the effect of SDF on bond strength may vary depending on the type of restorative material used.
