Abstract

Abstract:
Many studies in literature showed the effectiveness of silver diamine fluoride (SDF) and Nano silver fluoride (NSF) as preventive agents. However, there is little evidence regarding the retention properties of fissure sealant (FS) when applied on a surface previously treated with these preventive agents.
Objective: To evaluate and compare the effect of fissure pre-treatment with SDF versus NSF on the microleakage of FS in permanent teeth.
Methods: This experimental in vitro study was performed on 45 extracted human premolars, teeth were randomly assigned into three groups according to the type of fissure treatment: Group I: Control group (sealant only), Group II: SDF group (pre-treatment before sealant), and Group III: NSF group (pre-treatment before sealant). Teeth were thermos-cycled and then immersed in 2% methylene blue solution for 24 hours, teeth were then sectioned mesio-distally in the middle of the fissure, and examined under the stereomicroscope for dye penetration. Results: There was no statistical significant difference in the microleakage scores between the three groups (p=0.247). Conclusion: Pretreatment of the pits and fissure with SDF or NSF prior to sealant application did not affect the micro-leakage of the FS.
