Evaluation of Silver Diamine Fluoride and Sodium Fluoride Varnish in arresting caries progression on primary teeth: A comparative clinical study

Objectives: The aim of the present study was to compare the effectiveness of silver diamine fluoride (SDF) and sodium fluoride varnish in arresting caries progression on primary teeth. Subjects and methods: This study involved a total of 60 teeth categorized according to the restored primary teeth in two main groups; group A; Anterior teeth (n=30); group B; Posterior teeth (n=30). Then, the anterior teeth were subdivided into two subgroups (n=15); teeth restored with SDF alone (A1) or restored with NaF alone (A2) (n=15). While, the posterior teeth were subdivided into subdivided into two subgroups (n=15); teeth restored with SDF with ART “SMART” (B1) or restored with NaF with ART “SMART” (B2). The clinical and radiographic results in this study was evaluated after 3-months. Results: SDF showed significant clinical success when compared to NaF alone or when used under ART “SMART” technique. While, the anterior teeth showed better results than posterior teeth.the anterior teeth showed significant radiographic success when compared to posterior teeth. Conclusion: The use of SDF solution has better clinical and radiographic outcomes in caries arrest of primary teeth. SDF solution has better caries arrest outcomes in non-cavitated lesion than cavitated lesions in primary teeth.
