“…This finding is consistent with the results of studies by Teixeira et al and El-Desouky et al, who showed that NSF was more effective in increasing remineralization after pH cycling than the negative control samples. 29,30 El-Desouky et al concluded that NSF and fluoride varnish are equally effective anticariogenic materials in limiting enamel demineralization caused by cariogenic challenges. 30 This is in agreement with our results and proves both NSF and fluoride varnish effective in enhancing remineralization of enamel with no significant differences.…”

Background. Nano-silver fluoride (NSF) has been introduced to improve enamel lesions. The effective use of varnishes is important in the prevention of dental caries.Objectives. The study aimed to compare the effect of conventional sodium fluoride varnish with the same varnish containing 1% and 2% silver nanoparticles (AgNP) on the surface microhardness of enamel. Material and methods.The baseline surface microhardness of 40 premolar teeth was measured using a Vickers microhardness tester. After immersing the samples in a demineralizing agent for 24 h, the microhardness was measured again. In group B, a layer of conventional fluoride varnish was applied to the tooth surfaces using a microbrush with soft bristles, following the manufacturer's instructions. Groups C and D were treated with 1% and 2% NSF varnishes, respectively, while group A received no varnish. Surface microhardness tests were conducted on all specimens, including those previously tested.Results. The microhardness of the enamel surface increased significantly in all 3 test groups compared to the microhardness after demineralization (p < 0.05). Conclusions.Conventional fluoride varnish and fluoride varnishes containing 1% and 2% AgNP are equally effective in remineralizing initial caries.

“…Some studies concluded that NSF might be more effective than conventional fluoride preparations in treating incipient caries lesions [31,32]. On the other hand, some in vitro studies showed that the remineralization effect of NSF was lower [33] or similar to the effect of NaF varnish [34], but the fluorine content of the NSF used in these in vitro studies was 10,147 ppm, while NaF varnishes contained 22,600 ppm of fluoride.…”

Introduction:Globally, the increased prevalence of dental caries in children makes the need for dental remineralizing agents necessary. To the best of our knowledge there are a few published clinical trials on the effectiveness of nano-re-mineralizing agents but without comparing between them. Objectives: To compare nano-silver fluoride (NSF), nano-hydroxyapatite (n-HAP) and sodium fluoride (NaF) varnishes in prevention and arrestment of initial enamel caries on young permanent teeth. Material and methods: One hundred and fifteen children with ages ranging from 7 to 10 years were randomly divided into three groups: the NSF group (n = 39), the n-HAP group (n = 37) and the NaF group (n = 39). The clinical evaluation of dental surfaces was done by one masked examiner using ICDAS II to detect the number of new and arrested initial lesions. Varnish application was done annually for NSF, but it was done biannually for n-HAP and NaF. This was followed up at 3, 6 and 12-month intervals. The Kruskal-Wallis test was used to compare the groups. Results: After a follow-up period of 12 months, the NSF group had a significantly lower median number of new carious lesions, 1 (0), than the n-HAP group, 2 (3), with p = 0.01. There were significantly more arrested lesions in both NSF and NaF than in n-HAP at all visits, with p = 0.003, 0.01 and 0.002. At the level of children, the NSF group had the lowest number of children who were affected by new caries (23.1%) and the highest number of children who have arrested initial caries (87.2%). Conclusions: Annual application of NSF varnish might be recommended as an effective method of dental caries prevention and treatment of initial caries lesions.

“…It has been found to have larger bactericidal activity ( 19 ), non-toxic and safe for human use ( 20 ), with a potential advantage of not staining the teeth ( 15 ). A review of available literature revealed that a majority of the studies conducted on the effects of NSF were invitro ( 16 , 21 , 22 ). Thus, the present in vivo study was done to observe the effect of NSF varnish on oral S.mutans count and to compare it with sodium fluoride & chlorhexidine varnish.…”

Background This in vivo study was done to investigate the antimicrobial effectiveness of Nano Silver fluoride, Sodium fluoride and Chlorhexidine when used as a varnish on Streptococcus mutans ( S.mutans ) in saliva and plaque biofilm. Material and Methods 120 caries free subjects, aged 8-10 years were randomly assigned to four different groups (n=30) - group I: Control, group II: Chlorhexidine varnish (CHX), group III: Sodium fluoride varnish (NaF), group IV: Nano Silver fluoride varnish (NSF). Varnish application was done once at baseline. Saliva and plaque samples were collected at baseline (T0), at the end of 1 month (T1) and 3 months (T3) to evaluate S.mutans levels by culture method, optical density and PCR. OHI-S Index was also recorded for clinical evaluation. Results NSF, CHX and NaF were effective against S.mutans activity. The intragroup comparision of CFU/ml and OD/ml count showed a highly significant reduction from baseline to 3 months for all the 3 varnish groups ( p =0.001). PCR result revealed that maximum reduction was seen in NSF and CHX followed by NaF group. Conclusions NSF reduces S.mutans level in both saliva and plaque biofilm and it is more advantageous than CHX and NaF as it has dual properties of acting as an antibacterial as well as a remineralizing agent. Key words: Chlorhexidine, Nano Silver fluoride, Sodium fluoride, S. mutans, varnish.
