Learning Objective

At the end of the lesson, you will be able to explain the indications, mechanism, application steps, benefits, and limitations of silver diamine fluoride (SDF) in dental practice.

What do you already know about silver diamine fluoride?

Indications for SDF Application

SDF is mainly indicated for arresting active carious lesions, especially in populations where conventional treatment is not feasible or as interim therapy.

What Is Silver Diamine Fluoride?

Silver diamine fluoride (SDF) is a topical agent used in dentistry for caries arrest and prevention. It contains silver, fluoride, and ammonia.

Benefit of silver diamine Fluoride Application

A

Non-invasive and painless

B

Expensive

C

Caries Arrest

D

How Does SDF Work?

The silver component acts as an antimicrobial, fluoride promotes remineralisation, and ammonia stabilises the solution. Together, they halt caries progression.

Step-by-Step SDF Application

1. Isolate the area and dry the lesion. 2. Apply SDF with a microbrush to caries. 3. Allow to absorb for 1-3 minutes. 4. Blot excess and avoid saliva contamination. 5. Repeat if clinically indicated.

Precautions and Safety

Take care to protect soft tissues, as SDF stains mucosa and clothing. Check for allergies and avoid use on symptomatic pulp or ulcerated areas.

Benefits vs Limitations

• Causes permanent black staining of carious lesions • Metallic taste, rare allergic reactions • Not a definitive restoration

Benefits

Limitations

• Non-invasive and painless • Arrests caries effectively • Cost-effective and quick

Case Examples

SDF is useful for children, elderly, and patients with special needs. It can halt root caries in geriatric patients and manage early childhood caries.

Patient Communication

Explain the procedure, benefits, and expected black staining to patients or guardians. Obtain informed consent and answer questions proactively.

Summary: SDF in Modern Dentistry

SDF offers a minimally invasive, effective alternative for caries management. Understand its applications, limitations, and value in patient care.
