Silver diamine fluoride trial finds decay arrested in more than half of treated baby teeth
A Phase III trial involving 830 children younger than 6 evaluated 38% silver diamine fluoride (SDF) applied at six-month intervals. The report says treatment arrested decay in more than half of affected baby teeth; treated areas turn permanently dark, and SDF does not restore lost tooth structure.
- Phase III trial enrolled 830 children younger than 6.
- 38% SDF was applied at six-month intervals.
- Decay was arrested in more than half of affected teeth.
- Treatment permanently darkens decayed areas.
A Phase III clinical trial published in *JAMA Pediatrics* enrolled 830 children younger than 6 through dental clinics, pediatric medical practices, and Head Start programs in Michigan, New York, and Iowa. Researchers evaluated 38% silver diamine fluoride (SDF), applied to affected teeth at six-month intervals, for arresting decay in baby teeth.
The report says decay was arrested in more than half of the affected teeth. SDF is painted onto a cavity and does not require drilling, injections, or sedation. It can help prevent decay from progressing, but unlike a filling, it does not replace lost tooth structure.
The findings provide U.S. trial evidence for a treatment already used in other countries and used off-label in the United States for arresting decay. The product tested was Advantage Arrest 38% SDF, supplied by Elevate Oral Care. The report says the evidence may support an application for FDA approval for this use; it does not report a new approval. A key tradeoff is permanent dark discoloration of the treated decayed area. SDF may not suit every cavity, and treatment does not necessarily remove the need for later dental work.
In practice
For children younger than 6 with cavities in baby teeth, the trial supports SDF as a way to arrest decay without drilling, injections, or sedation. The report says more than half of affected teeth had decay arrested with 38% SDF applied at six-month intervals. This is not a replacement for lost tooth structure, and treated areas turn permanently dark; SDF may not be appropriate for every cavity or eliminate later dental work. The report does not describe a new FDA approval.
