SDF Innovation: Riva Star

The Original SDF System

Drawing on 50 years of dental research experience and proudly developed in SDI’s state of the art manufacturing facility in Australia, Riva Star is a silver diamine fluoride solution system used to desensitise tooth pain immediately.

This next generation SDF treatment delivers Minimal Intervention Dentistry that adopts the philosophy of integrating prevention, remineralisation and minimal intervention.

A Star Product Containing Three Powerful Components:

A Proven SDF Solution

Riva Star is a non-invasive 2 step patented system used to desensitise tooth pain in a few drops.

Two Years Desensitising Effect

A clinical study supports the immediate effect after one application with Riva Star, desensitisation lasts for 2 years.1

Effective Biofilm Inhibitor

Studies support that Riva Star is an effective Biofilm inhibitor. Riva Star has higher inhibition zones against four bacterial species (E.faecalis, S.gordonni, S.mutans, S.mitis) compared to sodium hypochlorite.2


Immediate Sensitivity Relief

The silver fluoride and potassium iodide in Riva Star blocks the microscopic tubules that make up dentine. A low-solubility precipitate is formed that gives instant relief.

Reduce Staining

Unlike other silver fluoride systems, the Riva Star two step procedure minimises the risk of staining. By applying the potassium iodide solution (KI) over the silver diamine fluoride (SDF), a silver iodide creamy white precipitate is formed which then turns clear.

Quicker and easier treatment

SDF treatment is quicker and easier compared to invasive treatment methods. SDF treatment delivers Minimal Intervention Dentistry that adopts the philosophy of integrating prevention, remineralisation and less invasive procedures.

1. Clean teeth with prophy paste and isolate area with cotton rolls.


2. Dry area and apply a small amount of Gingival Barrier to adjacent tissue. Protect lips with petroleum jelly/cocoa butter.

3. Light cure in a fanning motion.

4. Using silver brush, pierce foil on silver capsule. In circular motion, push foil to the edge of the opening.

5. Carefully apply solution from silver capsule to treatment site only.

6. Immediately using green brush, pierce foil on green capsule. In circular motion, push foil to the edge of the opening.

7. Apply generous amount of solution from green capsule to treatment site. Keep applying until creamy white turns clear.

8. Blot dry, remove gingival barrier.

CAUTION: The material could stain teeth if incorrectly used. Patient must be informed of this risk prior to its use.

Restoring Adult teeth in children

Here’s a great webinar on restoring adult teeth in children – When do you use a composite versus Glass Ionomer by Dr. Jarod Johnson.
Dr. Johnson has a private practice in Muscatine, Iowa. Dr. Johnson has received advanced training in behaviour management, sedation, hospital dentistry, trauma, special health care needs, interceptive orthodontics, space maintenance, oral hygiene and dietary counselling.
The objectives of this course is as follows,
1) Determine treatment options for permanent teeth impacted by caries or simple trauma
2) Choose the appropriate restorative material to achieve optimal outcomes in the developing dentition
3) Implement sectional matrices for Class II lesions in the posterior permanent dentition
4) Utilise Silver Diamine Flouride for minimally invasive dentistry and indirect pulp therapy
