Ideal for removing superficial white and brown decalcification stains due to enamel mottling from fluorosis, Opalustre is a 6.6% hydrochloric acid slurry that contains silicon carbide microparticles.1 This combination provides chemical stain removal along with gentle mechanical abrasion. OpalCups latch-type bristle polishing cups are used with the Opalustre for micropolishing the newly treated enamel surface. Both types of OpalCups are autoclavable through a limited number of cycles.
