White Class with calcium is a hydrogen peroxide-based dental whitening system in the concentrations of 4%, 6%, 7.5%, and 10%. Whitening gel for taking-home that use should be administered by the patient under the supervision of a dentist. It has a neutral pH, high water content, and the best desensitizing package on the market: potassium nitrate and sodium fluoride. Its major advantage is the addition of calcium in its formula to minimize the demineralization of the tooth enamel.
Characteristics and Advantages
• Its formula contains the best desensitizing package on the market: potassium nitrate and sodium fluoride. *
• It also has calcium to prevent the change in microhardness of the tooth enamel and to contribute to desensitization during its use.
• pH close to neutral.
• Shorter daily usage time.
• High water content to maintain dental hydration.
• The speed of initial whitening is faster.
• Does not interfere in the rugosity and microhardness of composite resins.
• Excellent viscosity: does not run off the dental tray.
• High yield: each syringe yields up to 9 complete applications on one arch.
This product is for professional dental use for whitening of vital teeth. It is intended for whitening done at home (also known as take-home whitening) and conducted under the supervision of a dentist. It is indicated for the following cases:
• Vital teeth darkened by age (physiological darkening).
• Naturally dark or yellow vital teeth.
• Vital teeth which are darkened or stained due to the intake of substances containing pigments such as coffee, tobacco, tea, etc.
• Stains of a mild to moderate intensity due to fluorosis.
• Vital teeth stained by tetracycline, in cases where the staining is mild.
Step by Step
Take the shade of the teeth so that the dentist and the patient have a clear point of comparison of the whitening procedure. The record of the color of the teeth can be done by using a shade guide or photography.
Impression: get the impression of the upper and lower arches with alginate.
The mold is made from stone plaster in order to avoid the formation of bubbles.
Preparation of the custom dental tray: in a vacuum-forming device, position the models in the tray and attach the 1 mm tray plate (Whiteness Plates for Custom Dental Trays – FGM). A dynamic bubble will form, showing its plastification. At this point, bring the plastified bubble toward the model, providing for a perfect fit. The removal of the plate should be done after it is fully cooled.
Trimming the dental tray: start the rough trimming of the plate, and then start trimming closer to the teeth. It is important for there to be no burrs so as not to cause discomfort to the patient. The trimming should be done by following the contour of the cervical region of the teeth or extending out 1 to 2 mm for the cervical region, e.g., covering part of the gingival tissue.
Testing the dental tray: check the fit of the tray, the pressure on the gingival tissue and discomfort during the movements of the lips, cheeks and tongue.
Amount of gel on the tray: it is very important to demonstrate to the patient the amount of gel that must be dispensed on the tray. One drop of gel on each tooth of the tray is sufficient. The gel should be placed in the regions corresponding to the vestibular faces of the teeth to be whitened.
Check the final appearance after treatment. Compare the initial and final photos.
1 – Try to guide the patient to strictly follow the instructions as received. The success of the treatment depends on the procedure being conducted properly.
2 – Tell the patient that it is normal during whitening to experience increased sensitivity of the teeth to temperature variations, especially cold. Some patients may feel slight irritation to the gums, tongue or lips, generally due to use of excessive gel in the tray. Advise them that they should always consult you if there is an exacerbation of symptoms.
3 – It is recommended to avoid ingestion of acidic food or beverages during whitening, because they may cause increased sensitivity during the procedure. Strongly colored food or beverages should also be avoided so that the whitening process is not compromised.
The presence of calcium has the purpose of preventing the process of alteration in the microhardness of the tooth enamel and contributing to desensitization during its use.
The treatment can be personalized (1 to 2 hours a day or on alternate days) according to the sensitivity and age of the patient and the concentration of the gel. During use of the gel, carefully follow the instructions of your dentist:
– White Class with calcium 4%: 2 hours a day
– White Class with calcium 6%: 1 hour and 30 hours a day
– White Class with calcium 7.5% 1 hour a day
– White Class with calcium 10%: 30 minutes a day (shorter time of daily use).
The whitener has potassium nitrate and sodium fluoride.
Information for the Professional
• It is normal for tooth sensitivity to occur during whitening. If sensitivity becomes uncomfortable, treat the teeth with Desensibilize KF 0.2% gel (moderate to low sensitivity) or Desensibilize 2% (moderate to high sensitivity). The higher the concentration of peroxide, the greater the possibility of having dental sensitivity.
• The whitening may reveal or highlight areas of hypocalcification due to the different (more intense) whitening of these areas. In some cases, these stains disappear due to dehydration of the enamel after the whitening is concluded. Treatment of these areas with fluoride may also assist in making them disappear.
• Store the product at temperatures of 5 to 20° C.
