Riva Star by SDI was introduced to the U.S. market earlier this year and has been getting a lot of buzz recently for its use as a desensitizing agent (that stops sensitivity immediately after use) and for containing silver diamine fluoride. We thought we’d share a little more about this product after our in-house hygienist expressed interest in the innovative way it worked.
At the moment Riva Star is registered solely as a desensitizer in the U.S. but silver diamine fluoride has known antibacterial properties that stop decay in teeth, and it has been registered as an anticaries agent in many other countries.
Silver diamine fluoride is a liquid that has the ability to stop tooth decay from progressing by killing the bacteria that causes decay. It also prevents future decay from developing, making it a useful product for dental practices or patients that prefer minimally invasive dental procedures, as it is a simpler procedure than a traditional filling.
However, one of the major drawbacks of using silver diamine fluoride in this way has always been tooth staining. Previous products containing this material have stained teeth black after treating decay, which can turn both patients and clinicians off from using this product as a caries arrester (when using as a desensitizer decay isn’t present so staining doesn’t occur).
Riva Star addresses this issue with an innovative two-step process. First, the silver diamine fluoride solution is applied to the tooth. The second step includes the application of potassium iodide solution, which forms a silver iodide precipitate that prevents the unsightly dark staining to appear. The result is a treatment area that matches the original tooth color.
If you use Riva Star to treat caries, it’s best suited for smaller cavities that can be treated with one application. For more progressed caries it can still be useful but may take more than one application for full effectiveness.
For offices who like to stay up to date on the latest and greatest innovations in the dental world Riva Star may be one to try. As the sole silver diamine fluoride product that does result in staining after treating caries, it could become a new clinician and patient favorite. If you plan on trying it let us know in the comments!
