A new silver diamine fluoride desensitizer from SDI Inc., Riva Star, has received registration approval for marketing in the United States.

Riva Star’s FDA registration is as a new-generation silver diamine fluoride desensitizer that immediately relieves tooth sensitivity. SDI Limited has already been successful in registering Riva Star as an anticaries agent in several Latin American countries, including Brazil, Peru, and Colombia.

Riva Star’s key ingredients are silver diamine fluoride and potassium iodide. Silver diamine fluoride has known antibacterial properties and stops decay in teeth. Combined with the potassium iodide, Riva Star has a higher inhibitory effect against four bacterial species, compared to sodium hypochlorite. (1)

Riva Star’s two-step globally patented procedure minimizes the risk of staining the tooth black. When the potassium iodide solution is applied over the silver diamine fluoride, a silver iodine precipitate is formed, which does not stain teeth as silver diamine fluoride used alone would. This patented two-step process results in an esthetically acceptable tooth-colored appearance for the patient.

Riva Star can be useful for clinicians who practice minimally invasive dentistry because it conditions dentin and may assist in tooth preservation. (2–5)

Riva Star’s capsule system is color-coded and easy to use, saving the clinician and patient time. Compared to bottles, the capsule system can also prevent spillage of silver diamine fluoride, which will stain surfaces black.

Riva Star increases bond strengths of glass ionomer cements. Pretreating the tooth surface with Riva Star can enhance the bonding of glass ionomers to dentin. (6)

Riva Star is available through all major dental distributors.
