CSL 8 SDF (easy)

Study Notes

Silver diamine fluoride (SDF) is a colorless fluoride delivery solution used to arrest tooth decay.
SDF contains approximately 44,800 ppm of fluoride and 255,000 ppm of silver.
SDF arrests active carious lesions in dentin.
The silver in SDF has antimicrobial properties, inhibiting further biofilm formation.
Fluoride in SDF stimulates remineralization of the affected tooth.
SDF is an economical and non-invasive way to manage tooth decay.
SDF is an invaluable tool for treating children who lack cooperation or have disabilities, limiting the options for managing their caries.
SDF is also a beneficial alternative when restorative options are not affordable or accessible.
SDF discolors the affected areas of the tooth dark.
Informed consent from the patient or guardian is crucial.

Active carious lesions (frank soft carious lesions in dentin) in primary teeth without pulp involvement.
Children with limited cooperation or disabilities.
Deep active carious lesions that need predictable arrest before restorative procedures.
Difficult to treat cavitated carious lesions where extensive tooth preparation is required.
Proximal lesions which are inaccessible for restorations.
Lower anterior primary teeth where restoration longevity is questionable.
Children with limited access to dental care.

SDF increases resistance to acid dissolution and enzymatic digestion through the formation of silver protein conjugates.
SDF increases the mineral density and hardness of the affected dentin by increasing hydroxyapatite and fluorapatite formation.
SDF has anti-protease activity, halting the breakdown of the dentinal organic matrix.
SDF directly kills cariogenic bacteria.
SDF-treated lesions are resistant to biofilm formation.

One drop of SDF is sufficient for roughly 6 teeth.
Isolation with cotton rolls is adequate.
Superficial loose debris should be removed.
The lesion should be air-dried.
SDF is scrubbed onto the lesion for one minute.
The lesion should be gently dried.
The site should be isolated for up to 3 minutes post-application.
Post application of SDF, a fluoride varnish may be applied to keep the SDF in contact with the lesion and mask the taste.
Patients should avoid eating or drinking for 30 minutes after SDF application.
