Study Notes

Non-restorative Cavity Control Using Silver Diamine Fluoride (SDF)

Silver diamine fluoride (SDF) is a colorless fluoride delivery solution.
SDF contains approximately 44,800 ppm fluoride and 255,000 ppm silver.
SDF arrests active carious lesions, especially in dentin.
SDF inhibits further biofilm formation.
SDF strengthens treated dentin, making it more resistant to cariogenic bacteria.
SDF remineralizes the lesion by stimulating fluoride activity.
SDF stabilizes the solution with ammonia.
SDF is economical and non-invasive for carious lesion management.
SDF discolors the arrested carious tissue black.
SDF is valuable for pre-cooperative children and in cases where operative care is limited by disabilities.
SDF is a beneficial alternative when restorative options are unavailable or are unaffordable.

Indications for SDF Use

Primary tooth surfaces with active cavitated dentinal lesions (frank soft carious lesions), no signs or symptoms of pulp involvement.
Children with cooperation limited by age or disabilities where conventional operative dentistry is challenging.
Deep active carious lesions, where clinicians desire to arrest lesion progression before restorative procedures.
Inaccessible proximal lesions requiring extensive tooth preparation for restorations.
Multi-surface dentinal lesions, or difficult to treat cavitated carious lesions.
Lower anterior primary teeth, when the longevity of the restoration is questionable.
Children with limited access to dental care.

Mechanism of Action (MoA)

SDF increases resistance to acid and enzymatic digestion via silver protein conjugates.
SDF increases the mineral density and hardness of hydroxyapatite and fluorapatite formation.
SDF contains anti-protease activity, which prevents the breakdown of the dentinal organic matrix.
SDF has a direct antibacterial action, killing cariogenic bacteria.
SDF-treated lesions resist biofilm formation.

Application Procedure

One drop of SDF is enough for roughly 6 teeth.
Cotton rolls are sufficient for isolation.
Superficial loose debris removal is required.
Dry the lesion before SDF application.
SDF application for a minute, followed by gentle drying.
Isolate the application site for up to 3 minutes post-application.
Apply fluoride varnish after SDF application to mask the taste and maintain contact with the lesion.
Patients should avoid eating or drinking for 30 minutes post treatment.

Protocols

Reapplication every 12 months (annual) or every 6 months (semi-annual).
