Abstract
Objective: A 1-year longitudinal study compared the effectiveness of annual and biannual silver diamine fluoride (SDF) applications on caries arrest among preschool children. Methods: A total of 295 children aged 2 to 3 years from 6 public preschools in Vietnam were selected and divided into 3 groups: Group 1 (G1) received annual SDF (n=90), Group 2 (G2) received biannual SDF (n=99), and Group 3 (G3) did not receive SDF (n=106). Clinical oral examination was performed at baseline, 6 months and 1 year. Results: Mean ds, the main component of dmfs, were 14.92 in G1, 15.91 in G2, and 18.17 in G3 at baseline, and no significant differences were found between the 3 groups. From baseline to 6 months and to 1 year, mean ds increased significantly in all children: 1.88 and 3.75 in G1, 2.22 and 3.47 in G2, and 5.20 and 8.91 in G3. Mean ds was significantly higher in G3 than G1 and G2 at 6 months and 1 year. At baseline, about 60% of active carious surfaces were treated with SDF in both G1 and G2. The proportions of arrested caries surfaces at 6 months and 1 year were 61.8% and 47.6% in G1, and 57.7% and 64.0% in G2. Significantly higher proportions of arrested caries surfaces were observed in G2 than G1 at 1 year. Conclusion: The study demonstrated a caries arresting effect of SDF in preschool children and its effect was greater after bi-annual application than annual application.
