Randomized controlled trial on the effectiveness of silver diamine fluoride in arresting caries in Lagos, Nigeria.

Treatment of dental caries in children still remains challenging due to lack of cooperation with conventional treatment modalities. Recently, the use of Silver Diamine Fluoride (SDF) has proved useful in addressing this challenge. Aim: This clinical trial aimed to evaluate the effectiveness of Silver Diamine Fluoride (SDF) in arresting caries in children in Lagos, Nigeria. Methods: This was a phase III balanced randomized controlled school based interventional study on 240 children. The study group was treated with SDF while GIC was used in the control group. Follow up visits in 2 weeks, 1 month, and 3 months were carried out to assess the treatment outcome. Inferential statistics with the use of Pearson Chi-square test and Independent Student t-test were used at 5% level of significance. Results: There was significant relationship between SDF and caries arrest in 2 weeks, 1 month and 3 months' assessment period (p = 0.001). The control group showed continuous decline (71.7%, 54.3% and 50.9%) in restorative success from 2 weeks to 3 months respectively. The mean ± SD and Confidence Interval (CI) of arrested caries in the SDF group were 113± 1.24 and 113.1 - 113.5 respectively. In the control group the mean ± SD and CI of restorative success were 69.3±11.8 and 67.2 - 71.4. The effect size was 5.24. Conclusion: The result of the study showed that SDF was effective in arresting caries in children without any harm and there was statistically significant difference in the use of 38% SDF in arresting caries in children.
