Antibacterial, Antiplaque and Anticaries Effect of Silver Diamine Fluoride and Fluoride Varnish in Children

Abstract

Aim: To compare the antibacterial, antiplaque and anticaries effect of silver diamine fluoride (SDF) and fluoride varnish in children.
Materials and Method: A total of 54 children, 12-14 years of age were included in the study. Children were divided into 3 Groups: - Group1: SDF, Group 2: Fluoride Varnish, Group 3: Normal Saline. All the children were evaluated for S. mutans count and Plaque score after 72hours, 3 and 6 months.
Result: In Group 1, statistically significant reduction in mean S. mutans count was seen after 3 days, 3 months and 6 months. However in group 2 and 3 significant reduction in mean S.mutans count was observed only after 3 days. A significant reduction in mean plaque score was seen after 3 days and 3 months in group 1, after 3 days in group 2 whereas after 3 days and 3 months in group 3. Intergroup comparison shows non -significant difference in mean S. mutans count and plaque score between group 1 and 2, while statistically significant difference in mean S. mutans count was found between group 1 and 3 and group 2 and 3 after 3 days, 3 and 6 months. Moreover, a significant difference was found in mean plaque score between group 1 and 3 and group 2 and 3 after 3 days, 3 and 6 months excluding a non-significant value after 3 months between group 2 and 3.
Conclusion: In vivo application of SDF and Fluoride varnish results in significant reduction in S. mutans count, plaque score and no carious lesion was detected after the follow-up time intervals.
