Pain, New Caries and Failure of Carious Primary Teeth after Application of Silver Diamine Fluoride Versus Sodium Fluoride Varnish: A Randomized Clinical Trial
Keywords:New caries, Early Childhood Caries, Conservative, Abscess, Pain
Background: The aim of this study was assessment of the pain, new caries and failure of carious primary
teeth after application of silver diamine fluoride versus sodium fluoride varnish immediately after application
and after 3,6,9,12, months.
Methods: This study was performed on 62 children with 255 carious primary teeth. After proper selection
according to eligibility criteria and proper diagnosis. They were randomly allocated (1:1) into two groups.
Group I (SDF): 38% Silver Diamine Fluoride and group II (NAF): 5% Sodium Fluoride Varnish. Assessment
of postoperative pain, new caries,and failure at baseline, after 3,6,9,12, months.
Results: Independent t-test was performed to compare between both groups and revealed that group II was
significantly higher than group I after 9 and 12 months regarding postoperative pain, new caries, and failure.
Also, strong positive significant correlation between failure and pain, and between failure and new caries
was found using Spearman`s correlation coefficient test.
Conclusions: SDF application isa successful alternative conservative treatment which eliminate the need
to general anesthesia. Also, it is inexpensive, fast, and pain-free procedure but it causes discoloration.
It`s successful results regardingstopping progression of new caries compensate its drawbacks such as
