| Abstract | ||||
| Introduction: Recently, Nanosilver fluoride (NSF) has raised in the field of caries prevention. Pit-and-fissure sealants could have an additional antibacterial and remineralizing benefit through enamel pretreatment by NSF. Objectives: to evaluate in-vitro the effect of NSF pretreatment on shear bond strength, marginal seal, and quantity of color change of pit and fissure sealant in comparison to sealant only in permanent teeth. Materials and Methods: Fifty-four freshly extracted permanent teeth were collected and randomly allocated into two groups: Group I: (n=27) NSF was applied to the enamel prior to sealant application. Group II: (n= 27) enamel was etched and sealed. Each group was divided into three subgroups according to the test applied. (n= 9 teeth each). Subgroup A: Shear bond strength was measured using a Universal Test Machine. The deboned area was examined under stereomicroscope to assess the mode of failure. Subgroup B: Microleakage samples were examined under a stereomicroscope to assess the degree of microleakage. Subgroup C: Color Assessment: After a sealant application, any change in sealant color was evaluated using a spectrophotometer. Results: no statistically significant difference between both subgroups neither in shear bond strength nor microleakage. The comparison of the final color of sealants in both subgroups showed a higher color change in subgroup Ic with a significant difference (P-value =0.001). Conclusion: Pretreatment with nanosilver fluoride prior to pit-and-fissure sealant application did not affect neither its shear bond strength nor its sealing ability. However, it altered the sealant color to an extent that exceeded the clinical acceptance levels. | ||||
