Double Desensitizing Action: Neural action of potassium nitrate and occlusive sodium fluoride. Potassium nitrate is an effective agent in the treatment of hyperesthetic dentin. Its action is based on the fact that the increased concentration of extracellular potassium depolarizes the membranes of nerve fibers, blocking the passage of the stimulus, reducing hypersensitivity.
Calcium: Prevents demineralization and reduces hypersensitivity.
Quickness: Shorter daily wearing time.
4%: 2 hours a day,
6%: 1 hour and 30 hours a day
7,5%: 1 hour a day
10%: 30 minutes a day
• Whitening of vital teeth using the at-home whitening technique supervised by a dentist.
Step by step
Register the teeth shade so that the dentist and the patient can have a comparison parameter for the whitening. Recording of teeth shade can be made using a shade guide or a photograph.
Molding: molding can be made with alginate and must properly copy all teeth that will be whitened.
Mold is made of stone-gypsum, in order to prevent bubbles. It is not necessary to relief the model to create gel shells.
Place the 1mm acetate plate Whiteness Plates for Molds (FGM) into the thermal laminator until forming a slight bending due to the heat. Then, pull the plastic state plate over the gypsum model, so the suction can thermal format the mold into the model. The plate’s removal must be made after it has fully cooled down.
After removing the mold from the model, cut it without burrs and to cover 1 to 2mm of the gums margin.
Mold test: the mold must not compress the soft tissue, nor present excessive gaps.
Show to the patient the quantity of gel that should be applied to the tray. One drop of gel must be put into the areas corresponding to the vestibular faces of the teeth that will be whitened. Usage time: 2 hours per day for 4% concentration; 1 ½ hour per day for 6% concentration; 1 hour per day for 7.5% concentration; and 30 minutes per day for 10% concentration.
The regular consultations of the patient should be scheduled on weekly basis, until completing the treatment. Record the final shade achieved.
