Aim: The purpose of the present study is to evaluate the effect of nanosilver fluoride (NSF), chlorhexidine (CHX), and sodium fluoride (NaF) when used as a varnish on Streptococcus mutans levels in children with dental caries.
Study design: A total of 120 children (age range 8–12 years) with incipient caries were randomly assigned to four groups (n = 30): group I—NSF varnish, group II—CHX varnish, group III—NaF varnish, and group IV—control. Varnish application at baseline was performed once. To assess the levels of S. mutans using the culture method [colony-forming units (CFUs)] and optical density (OD), plaque and samples were taken at baseline (T0), 1 month (T1), and 3 months (T3). Additionally, the oral hygiene index-simplified (OHI-S) was noted for clinical assessment.
Results: By the end of 3 months, a statistically significant reduction in plaque CFU and salivary CFU was found in group II. At the conclusion of the 3 months, group I had the greatest decrease in OHI-S. After 3 months, the plaque CFU score did not differ significantly across groups I, II, and III. However, a statistically significant difference in OD values (p-value of 0.00) was discovered between group I and all other groups.
Conclusion: Children with early caries can effectively lower their S. mutans count by using NSF varnish.
