SDI Introduces Riva Star
SDI (North America), Inc. is pleased to announce that the FDA has given registration approval to market Riva Star in the USA.
Riva Star’s FDA registration is as a new generation SDF (silver diamine fluoride) desensitiser that immediately relieves tooth sensitivity. SDI Limited has already been successful in registering Riva Star in several key Latin American countries such as Brazil, Peru, and Colombia as an anti-caries (decay) agent.
Riva Star’s key ingredients are silver diamine fluoride (SDF) and potassium iodide (KI). SDF has known antibacterial activity which stops decay in teeth. Combined with the KI, Riva Star has a higher inhibition zone against four bacterial species compared to sodium hypochlorite1.
Unlike any other SDF based system, Riva Star’s two step globally patented procedure minimises the risk of staining the tooth black. By applying the KI solution over the SDF, a silver iodine precipitate is formed which does not stain teeth as does using other SDF treatments alone. This patented two-step process results in an aesthetically acceptable tooth coloured appearance for the patient.
Riva Star is essential for clinicians practicing Minimally Invasive Dentistry (MID)2-5. It conditions dentin and may assist in tooth preservation.
Riva Star’s unique capsule system is colour-coded and extremely easy to use, saving the clinician and patient precious time. The capsule system also prevents the spillage of SDF normally supplied in bottles, which will stain surfaces black.
Riva Star increases bond strengths of glass ionomer cements. Pre-treating the tooth surface with Riva Star is a great way to enhance bonding of glass ionomers to dentin6.
Riva Star is a revolutionary desensitising star, a solution and innovation to the dental industry in reducing tooth sensitivity for patients without the negative aesthetic effects of other silver diamine fluoride products.
