BACKGROUND: Nano-silver fluoride (NSF) has emerged as a promising agent in enhancing the antibacterial and remineralizing properties of pit-and-fissure sealants. It improves the overall effectiveness and longevity of sealants in preventing dental caries.
AIM: To evaluate in vitro effects of NSF and silver diamine fluoride (SDF) pretreatment on the shear bond strength (SBS), marginal seal, and color stability of pit-and-fissure sealants compared to sealants applied directly on primary teeth.
METHODS: A total of 108 freshly extracted primary teeth were randomly divided into three groups: Group I (n = 36) received NSF pretreatment before sealant application, group II (n = 36) received SDF pretreatment before sealant application, and group III (n = 36) was etched and sealed without pretreatment. The samples were assessed for SBS, microleakage, and color assessment, and subjected to statistical analysis.
RESULTS: Shear bond strength was slightly higher for the NSF group. The intergroup comparison showed higher microleakage for group III. A significant color difference was seen between the three groups. The highest color change was seen in the SDF group.
CONCLUSION: Pretreatment with NSF prior to pit-and-fissure sealant application is more effective.
