Next Generation SDF System

SDI continues to innovate SDF solutions by releasing Riva Star Aqua, a next generation water-based silver fluoride solution that is also effective in arresting carious lesions as an SDF solution, with additional patient benefits.

Similar to Riva Star (SDF), Riva Star Aqua (AgF) is also a non-invasive 2 step patented system used to desensitise tooth pain in a few drops. Riva Star Aqua is an aqueous silver fluoride solution without the Ammonia base.

Clinical Match to SDF

Clinical studies have shown that Riva Star Aqua’s 38% Silver Fluoride (SF) is also an effective desensitiser  as Riva Star SDF solution containing 38% Silver Fluoride.1

Reduce Staining

Just like Riva Star, Riva Star Aqua includes a Potassium Iodide (KI) Step 2 solution, for significantly reducing unsightly black stains.

Improved Smell

The ammonia free solution tastes and smells better, leading to happier, more compliant patients.

Effective Biofilm Inhibitor

Studies support that Riva Star is an effective Biofilm inhibitor. Riva Star has a higher inhabitation zone against four bacterial species compared to sodium hypochlorite.2

Immediate Sensitivity Relief

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

Two Years Desensitising Effect

A clinical study supports the immediate effect after one application with Riva Star, desensitisation lasts for 2 years.3

No Tissue Burn Risk

Riva Star Aqua is water based and ammonia free. This reduces soft tissue irritation and eliminates odours while improving storage stability.

No Gingival Barrier Required

With no ammonia present, Riva Star Aqua can be safely used without a gingival barrier as soft tissue irritation is significantly reduced. Treatment time is quicker and more comfortable on patients.
