Sensitivity eliminator

A STAR product containing three powerful components:

Together, these have a powerful effect to provide instantaneous relief to hypersensitivity.


Riva Star was designed by three renowned Australian clinicians, bringing together their clinical knowledge and experience of using these three exceptional components, and combining them into one STAR product – Riva Star!

Riva Star – Other benefits

Riva Star is essential for clinicians practising minimally invasive dentistry1-3,5.  It conditions dentine and may assist tooth preservation4,5.

Riva Star – Increasing bond strengths of GICs

Pre-treating tooth surfaces with Riva Star is a great way to enhance bonding of glass ionomers to dentine4.

Riva Star – Patented procedure

Unlike other silver fluoride systems, Riva Star’s two step patented procedure minimises the risk of staining. By applying the potassium iodide solution over the silver fluoride, a silver iodide creamy white precipitate is formed and then turns clear.

Riva Star – A desensitising star offering immediate relief

The silver fluoride and potassium iodide action in Riva Star blocks the microscopic tubules that make up dentine. A low-solubility precipitate is formed that gives instant relief. It acts by preventing the flow of fluid that produces sensitivity 3.

Riva Star – Two years and beyond esensitising effect

A clinical study supports the immediate effect after one application with Riva Star. Desensitisation lasts at least 2 years6.

Riva Star – Indications

  • Desentising cervical tooth hypersensitivity.

Each pair of capsules (green and silver) can treat up to 5 teeth on a patient.

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.

3. Light cure in a fanning motion.

4. Using silver brush, pierce foil on silver capsule.

5. In circular motion push foil to the edge of the opening.

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

7. Immediately using green brush, pierce foil on green capsule.

8. In circular motion push foil to the edge of the opening.

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

10. Blot dry, remove gingival barrier.

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