Tooth desensitizing agent and cavity cleaner. Riva Star uses a triple-action approach to reduce dental sensitivity, achieving an instant effect. It has the action of fluoride and silver iodide as well as the patented reinforcement effect of potassium iodide to block the dentinal tubules where patient sensitivity starts. This powerful combination provides the necessary relief for hypersensitive teeth, as well as offering antibacterial activity by forming a layer of low precipitation that creates an efficient inhibitory biofilm layer. Minimally invasive, it conditions the dentine and helps to preserve the teeth and patient wellbeing. In addition to being a restorative process, the increase in the bonding resistances of the GIC with tooth surface pretreatment with Riva Star is an excellent way of improving the union of glass ionomers on dentine. For use in adults over 21.
