NEXT GENERATION SDF: RIVA STAR AQUA
SDI continues to innovate silver fluoride technologies with the development of Riva Star Aqua, the next generation water based silver fluoride system. Riva Star Aqua is also a two-step patented system used to desensitise teeth in a few drops.
Riva Star Aqua is an aqueous silver fluoride solution without the ammonia base.

Riva Star Aqua Key Benefits
Similar Performance To SDF 4
Studies have shown that Riva Star Aqua’s ammonia-free formulation is as effective as Riva Star SDF.
Riva Star Step 2 For Reduced Staining 3
Riva Star Aqua is not expected to stain sound tooth structure. In the case of contact with unsound tooth structure, Riva Star Step 2 will reduce the staining. By applying potassium iodide solution (KI) over Riva Star Aqua, a silver iodide creamy white precipitate is formed which then turns clear.
Instant Sensitivity Relief 1
The silver fluoride and potassium iodide in Riva Star forms a low-solubility precipitate that blocks the microscopic dentinal tubules, providing instant relief.

Two-Years Of Effective Desensitising 2
Building on the proven clinical performance of Riva Star, Riva Star Aqua is expected to deliver immediate desensitisation with long-lasting effect of up to two years.
Odourless Formulation With Minimised Soft Tissue Irritation5
Riva Star Aqua is water-based and ammonia free. This reduces soft tissue irritation and eliminates the ammonia odour that may be a barrier to patient acceptance.
No Gingival Barrier Required 6
As no ammonia is present, the potential for irritation is reduced. Therefore, Riva Star Aqua can be used with simple soft tissue protection methods (e.g: cocoa butter) instead of Gingival Barrier (SDI Limited). Treatment time is quicker and more comfortable for patients.
INTENDED USE
Riva Star Aqua is used by dental professionals to desensitise cervical tooth hypersensitivity.
INDICATIONS
Desensitising cervical tooth hypersensitivity.
CONTRAINDICATIONS
- Do not use on patients with known thyroid conditions.
- Do not use on patients who have a history of allergies to silver, fluoride, potassium and/or iodine.
- Do not use on pregnant or lactating women.
Note: If in doubt, consult a doctor or an allergy specialist before use.
INTERACTIONS
Residual precipitate or moisture may reduce the bond strength of resin based adhesives.
SIDE EFFECTS
- Contact with soft tissues may cause inflamed tissues / aphthous ulcers in the mouth and temporary staining.
- Permanent staining of unsound tooth structure.
PRECAUTIONS
- Patient must be informed of potential tooth staining prior to treatment.
- Due to potential staining, it is recommended that anterior teeth not be treated.
- Avoid contact of Riva Star Aqua solution with oral soft tissue, eyes and skin.
- Use on soft dentine may cause staining.
- Solution from Riva Star Aqua Step 1 will stain surfaces. Wear gloves and eye protection when handling (see “HANDLING STAINS”).
- Possible patient discomfort due to metallic taste.
- Capsules are single use only.
- For professional use only.
- Keep out of reach of children.
- Do not take internally.
- Do not use after expiry date.
