Final answer:
Silver diamine fluoride is applied by isolating and drying the tooth, applying the SDF solution to the decayed areas using an applicator, and letting it dry. A follow-up application may be necessary, and it is not a restorative treatment.
Step-by-step explanation:
Silver diamine fluoride (SDF) application is a minimally invasive dental treatment used to stop the progression of caries (tooth decay). It is particularly effective in managing caries in patients who are not good candidates for traditional dental treatment due to age, behavioral challenges, or medical concerns. The application process is straightforward:
- The teeth to be treated are isolated and dried.
- A small amount of SDF solution is placed on a microbrush or a similar applicator.
- The solution is then carefully applied to the carious lesions on the teeth.
- Excess solution is removed, and the area is allowed to dry.
- Protective barriers like a rubber dam or cotton rolls may be used to prevent the solution from contacting soft tissues, as SDF can cause staining.
- After application, the treated area turns black as the silver component reacts with the decayed tooth structure.
It is important to note that SDF application may need to be repeated at follow-up visits to fully arrest the decay. Additionally, this treatment does not restore tooth form or function. In cases where esthetics are a concern, alternate treatment options may be considered.
