Abstract: Objectives: The purposes of this study were to investigate the caries arresting effect of silver diamine fluoride (SDF) on primary tooth surfaces, and to assess the effect of SDF on cariogenic bacteria among Myanmar children.

Methods:
A 6-month intervention study was conducted for 201 preschool children, who were allocated to two groups; Group A received SDF and sodium fluoride (NaF) applications, and Group B received only NaF application. A clinical oral examination, caries risk tests and oral health education were performed at baseline and 6-month follow-up.

Results: All caries risk test scores significantly decreased in Group A, but no significant changes in Group B after six months. In Group A, the proportion of arrested carious surfaces was 72.0% at 6-month follow-up. Overall, the incisors showed the highest proportion of arrested carious lesions while second molars had the lowest in both arches. The buccal lesions were most arrested by SDF in both anterior and posterior teeth. Lingual lesions in anterior teeth and the distal lesions in posterior teeth were least arrested by SDF.

Conclusion: SDF was effective not only in arresting carious lesions but also in diminishing the quantity of cariogenic bacteria present and acid production.
