Teeth stains have many causes, and mostly are extrinsic teeth stains. An extrinsic tooth stain is staining on the surface of the tooth. It occurs when stain particles, such as pigmented residue from food, drink or tobacco. This type of tooth stain responds well to regular dental cleaning and brushing the teeth with whitening toothpaste.
Today case is about intrinsic stain. An intrinsic tooth stain is staining below the surface of the tooth. It occurs when stain-causing particles work through the exterior of the tooth and accumulate within the tooth enamel.
An intrinsic tooth stain is trickier to remove, but it can be done. If the accumulative stain layer is shallow and superficial on enamel, less than 0.2mm, we can combine teeth whitening and micro-abrasion technique to remove the intrinsic stain.
Opalustre™ produced by Ultradent® (USA) , is ideal for removing superficial white and brown decalcification stains due to enamel mottling from fluorosis, Opalustre 6.6% hydrochloric acid slurry contains silicon carbide microparticles. This combination provides chemical stain removal along with gentle mechanical abrasion. OpalCups latch-type bristle polishing cups are used with the Opalustre slurry for micropolishing the newly treated enamel surface.
~Removes superficial white and brown stains
~Provides minimally invasive treatment for fluorosis
~Hydrochloric acid aids in chemical stain removal
~Silicon carbide microparticles provide gentle mechanical abrasion
~Less than 0.2mm enamel removal
Treatment Procedure & Result
We used Opaluscence Boost 35% Carbamide Peroxide, 2 cycles (40 minutes) of whitening gel application as the first procedure. Then proceed with micro-abrasion to remove the intrinsic stain with Opalustre.
Patient concern about the brown intrinsic stain.
One visit in-office whitening with Opalescence Boost 35% for 40 minutes.
The stain removed with micro-abrasion technique under rubber dam protection.
