In-office whitening procedures usually a use hydrogen peroxide solution with a light source for activation

“Power bleaching” can bleach your teeth in a single visit with peroxide and the light source Slide5

Hydrogen peroxide formula contains 15-38% peroxide

 In clinical studies, results show when the light source is added the results are better



As much as a 2 shade improvement with the light source Slide6

Study by

britesmile: One group of subjects with hydrogen peroxide, one group with just the light, and then one group with combined peroxide and light. 96.6% with the combined product said it greatly whitened their teeth

39.3% with peroxide alone said moderately whiter53.5% with light alone said moderately whiter alsoSlide7

Stains best removed from in-office whitening:

Aging, foods (coffee, red wine, sodas), tobacco useStains that are resistant to in-office whitening:

Inorganic stains, trauma which causes dentin to be darker, tetracycline antibiotics, overexposure to fluorideSlide8

Disadvantage: sensitivity

3 months after clinical study subjects were asked how sensitivite their teeth had become Peroxide and light group and the peroxide alone group had a greater sensitivity than the light treatment group

Slide9

Costs: in-office treatment $650 compared to $100 or less for over the counter treatments

This is not a permanent solution so follow up appointments are necessary alsoSlide10

General facts (not necessarily trays we can put this anywhere in the pwrpt

if you want!)Whitening should be accompanied with remineralizing techniques (fluoride and calcium phosphate applications)Potential demineralization effects from a daily whitening regimen is comparable to drinking a cola beverage or glass of orange juiceSlide19

Whitening StripsSlide21

What are Whitening Strips

Over-the-counter remedy that bleaches for a whiter smileCompared to other whitening methods, consumer prefer strips because they are easy to use, comfortable to wear, are more cost effective and provide more consistent resultsSlide22

How do they work?

Apply a thin strip of plastic to the front of both the upper and lower teethOne side of the plastic is coated with a bleaching agent called hydrogen peroxideOnce the plastic strips are in place, press them against the teeth for maximum contactThe strip is kept for a certain period of time depending on the concentration of hydrogen peroxide and the brand being usedSlide23

Different Brands( Remembrandt versus Crest)

Differing brands will have different concentrations of hydrogen peroxide within their stripsSlide24

Crest whitening strips

Examples: Crest 3D White Professional Effects, Crest 3D White Advanced Uses 6.5% concentration of hydrogen peroxide in most of their productsStudies have supported that Crest Whitening strips remove both extrinsic stains (coffee, soda) and intrinsic stains (tetracycline)Slide25

Crest Whitening Effectiveness:

Candidates were instructed to note any change in their tooth coloring on a daily basis for the duration of the study. Candidates reported that they noticed a significant change within the first week and still better results within the preceding weeksSlide26

Disadvantages:

There are several side effects that are caused by whitening products/whitening stripsThe most two prevalent being tooth sensitivity and gingival irritation.Slide32

Tooth Sensitivity:

A layer of hard enamel protects the crowns of your teethA layer of cementum protects the tooth root under the gum line.Gum tissue is a protective blanket that covers the tooth roots.Underneath the hard enamel, or cementum, is the porous dentin which is made up of tiny openings, called tubules or channelsSlide33

Tooth sensitivity cont.

Inside each tubule lies a nerve that comes from the tooths pulpWhen the dentin loses its protective covering or is exposed, it may cause hypersensitivity and discomfort when you drink cold or hot liquids, eat sweet or sour foods, or when you breathe through your mouthThe nerves inside the tooth get stimulated causing everything from discomfort to a sharp, sudden, shooting pain deep into the nerve endings of your teethSlide34
Slide35
Slide36

Gingival irritation:

Gingiva irritation is caused by the high levels of hydrogen peroxide in the whitening products touching the gingivaThis causes a burning sensation and is uncomfortable for the user Slide37

Other adverse effects:

Mucosal irritation, alteration of the enamel surface, and negative effects on restorations (not as common)It is important to note that a woman who is pregnant should not use whitening products because, although there is no evidence of this, could cause damage to the fetus
