The aim of this article is to review the knowledge of silver diamine fluoride (SDF) for
arresting dental caries in primary teeth. The advantages of SDF are ease of use and its safety.
The concentration of SDF used in Thailand for arresting dental caries in primary teeth is 38% or with
44,800 ppm fluoride. The effectiveness of SDF for arresting dental caries in primary teeth ranged
between 70-90%. Frequency of application is 1-2 times per year. The evidences show higher
effectiveness for 2 times of application than for 1 time per year. The caution of using is that SDF is
indicated only for non-exposed carious lesions or vital dental pulp. The main disadvantages are
discoloration or blackened carious lesion as well as black stain on contacted tissue. However, due
to high concentration of fluoride in SDF, care should be taken during application. Because of its
advantages and effectiveness, SDF is an alternative for arresting dental caries in primary teeth and
further studies should be done on cost-effectiveness, optimum frequency of application and the effect
on permanent teeth.
