Comparative Evaluation of the Shear Bond Strength of Self-Adhesive and Glass Ionomer Cement to Dentin After Removal of Hemostatic Agents Using Different Cleansing Protocols: An In Vitro Study

Background Hemostatic agents (HA), such as aluminium chloride (AlCl3) and ferric sulfate (FeSO4), can affect the dentin by obstructing adhesive penetration, and reducing the bond strength of self-adhesive resin cements (SARC) and glass ionomer cements (GIC). Aim To evaluate and compare the shear bond strength (SBS) of bonding and luting agents (SARC and GIC) to dentin after the removal of AlCl3 and FeSO4, using different cleansing protocols (dentin conditioner (DC) and ethylenediaminetetraacetic acid (EDTA)), and to determine whether the same cleansing protocol can be applied for both bonding and luting procedures. Methodology Sixty molar teeth were sectioned and categorized into two HA groups and three cleansing-protocol subgroups. Within each subgroup, specimens were bonded with SARC and GIC. SBS was evaluated, and data were statistically analyzed using independent t-tests, one-way and three-way analysis of variance (ANOVA), with the level of significance established at p < 0.05 Results For SARC, EDTA yielded the highest SBS after both FeSO4 and AlCl3 contamination, followed by DC and control (p < 0.001). For GIC, DC produced the greatest SBS after AlCl3 contamination (p = 0.042), whereas EDTA was most effective after FeSO4 contamination (p = 0.017). Control groups consistently showed the lowest SBS values. Conclusion EDTA is the preferred cleanser for SARC after use of both contaminants, and for GIC following FeSO4 contamination, while DC was preferred for GIC after AlCl3.
