Dental caries is the most common disease in childhood and has an impact on general health status. The topical application of fluoride varnishes has been used for the prevention and control of dental caries due to their high fluoride content, adhesion capacity, and safety. Silver has a varied application in medicine as well as in dentistry due to its anticaries, antimicrobial, and antirheumatic potentials. The introduction of nanosilver fluoride (NSF) was made with advancements in technology to overcome the drawbacks of silver diamine fluoride (SDF).
To compare and evaluate the microhardness and microleakage of NSF varnish and sodium fluoride (NaF) varnish.
An comparative experimental study was carried out between synthesized NSF and commercially available NaF, with 20 samples in each group. The specimens were sectioned and subjected to microhardness evaluation using Vickers microhardness testing and the dye penetration method to evaluate the microleakage.
The average microhardness was found to be 230.7218 VMH for NSF (group I), 198.9841 VMH for NaF (group II), and 91.6120 VMH for group III. These differences were statistically significant when compared with each other ( = 0.002). In 50% of the samples, no dye penetration was seen in the NSF group, compared to the NaF varnish group, where 75% of the samples exhibited penetration onto the varnish interface or the varnish and tooth interface.
Nanosilver fluoride proves to be an effective alternative to commercially available topical fluoride agents such as NaF. It has greater microhardness and lower microleakage than NaF and the control teeth.
Nanosilver fluoride varnish can be used as a cost-effective alternative to NaF varnish and SDF. It can be applied with minimal training by healthcare workers or general practitioners.

龋齿是儿童时期最常见的疾病，会影响整体健康状况。由于含氟量高、附着力强且安全性好，氟化物清漆的局部应用已被用于预防和控制龋齿。银因其防龋、抗菌和抗风湿的潜力，在医学和牙科领域有多种应用。随着技术进步引入了纳米银氟化物（NSF），以克服二胺银氟化物（SDF）的缺点。
比较和评估NSF清漆和氟化钠（NaF）清漆的显微硬度和微渗漏情况。
对合成的NSF和市售NaF进行了对比实验研究，每组20个样本。将标本切片，使用维氏显微硬度测试进行显微硬度评估，并采用染料渗透法评估微渗漏情况。
NSF组（I组）的平均显微硬度为230.7218维氏显微硬度（VMH），NaF组（II组）为198.9841 VMH，III组为91.6120 VMH。相互比较时，这些差异具有统计学意义（P = 0.002）。与NaF清漆组相比，NSF组50%的样本未观察到染料渗透，而NaF清漆组75%的样本在清漆界面或清漆与牙齿界面出现渗透。
纳米银氟化物被证明是市售局部用氟化物制剂（如NaF）的有效替代品。它比NaF和对照牙齿具有更高的显微硬度和更低的微渗漏。
纳米银氟化物清漆可作为NaF清漆和SDF的经济有效替代品。医护人员或全科医生经过最少培训即可应用。
