Silver diamine fluoride therapy established caries treatment but application protocols varied, different

Results:

• The review included 14 protocols from 15 publications from 4 manufacturers, 3 dental associations, and 7 author teams (one team had 2 articles).
• The American Dental Association and the British Society of Paediatric Dentistry provided their SDF application protocols on YouTube.
• The American Academy of Paediatric Dentistry and 7 author teams published their protocols in journal articles. Seven publications suggested an SDF application time of 60 seconds.
• Seven publications suggested a time range of 10 seconds to 240 seconds.
• Two publications suggested caries excavation, but 4 publications suggested no caries excavation before SDF application.
• The procedures from at least 5 publications involved protecting the gingiva with petroleum jelly, isolating the carious tooth with cotton rolls, drying the carious lesion with a 3-in-1 syringe, applying SDF solution with a micro brush for 60 seconds, removing excess SDF solution with gauze, and applying fluoride varnish to the SDF-treated lesion.

Although the SDF application protocol is simple and straightforward, the published protocols could be different. Most publications suggested an SDF application time of 60 seconds, which can be long, particularly for young children and older adults.
