£75 reduction in the cost of Britesmile Whitening

The bleaching gel oxidises the staining and draws out the stain,it doesnt damage the enamel.

RT, apologies and thanks for the explanation. On second reading, yes, I can see you can have both probably and certainly. But now you have both certainly and extremely unlikely?  

??? I thought both RT's explanations were perfectly clear and nothing wrong with the language used!

Hiya,

This isn't a plug but I work for an online cosmetic treatment information website called the Consulting Room. I won't put the website address in in case Martin thinks I'm advertising but you can find it on Google if you want to. Anyway, we cover info on tooth whitening as well as loads of cosmetic surgery and beauty treatments, and I also do research for newsletters that we send out to the public and to clinics. Anyway, this month some nice clinical info on the Colgate whitening gel from the US that has been discussed on here has come up that I thought might be valuable to you all. I too am researching the subject to get it done on my partner as a treat before our wedding next year so am finding this thread informative, thanks.

Anyway, here's the clinical info. ;D

Comparative tooth whitening efficacy of 18% carbamide peroxide liquid whitening gel using three different regimens.

OBJECTIVE: Recently, a novel paint-on liquid whitening gel--Colgate Simply White Clear Whitening Gel--which contains 18% carbamide peroxide, has been developed as a self-administered tooth bleaching system. The purpose of the present study was to determine the efficacy and safety of this product using alternate exaggerated or simplified treatment regimens.

METHODOLOGY: This was a three-week clinical trial using a parallel, double-blind, stratified protocol with three different instructions for application: 1) twice-daily, no air-drying, and 15 minutes without eating/drinking; 2) three times daily, 30-second air-drying and 30 minutes without eating/drinking; or 3) four times daily, 30-second air-drying and 30 minutes without eating/drinking. One-hundred and twenty (120) healthy volunteers were balanced into three equal groups based on shade scores (A3 or darker). Clinical evaluations (shade guide, oral tissue health, gingival index and visual analog sensitivity score) were performed on each group at baseline and weekly for the next 21 days. At the conclusion of the study, a survey of the subjects' opinions on their assigned product regimen was also conducted.

RESULTS: Subjects who used Colgate Simply White Clear Whitening Gel three and four times daily achieved the greatest shade improvement (5.88 +/- 1.53 shades, and 5.57 +/- 1.54, respectively). However, these values were only about one shade better than the value observed for the more convenient, twice-daily, "no-dry" regimen (4.51 +/- 1.77 shades), though they were statistically significant (p < 0.05). The result for the four-times daily protocol was not statistically different from the three-times group. Also, no differences were observed between the groups concerning oral tissue health, gingival index or tooth sensitivity, and no adverse effects were observed or reported regardless of the regimen used. Surveys completed by the subjects showed that those who used the twice-daily, "no-dry" regimen found the product to be the easiest to use, the most comfortable and the most pleasant tasting.

CONCLUSION: It can be concluded from the clinical data that three or four applications of Colgate Simply White Clear Whitening Gel per day provided better efficacy. In addition, the use of the whitening gel twice daily, even without "dry time" and only 15 minutes without eating/drinking, yielded results that were comparable to previously reported results using the original on-label directions. The potential additional benefit to the "simplified regimen" is that it was perceived to be the most convenient and comfortable. The use of Colgate Simply White Clear Whitening Gel up to four times daily for up to three weeks is also safe, and the tendency of abusing the product with more frequent daily use may be deterred by the inconvenience reported by the study subjects.

Here's some more...

Efficacy and safety assessment of a new liquid tooth whitening gel containing 5.9% hydrogen peroxide.

PURPOSE: To evaluate the efficacy and safety of a new 5.9% hydrogen peroxide liquid, invisible gel, (Colgate Simply-White Whitening Gel).

METHODS: A total of 30 subjects were enrolled into the study and divided into two treatment groups (Colgate vs. placebo gel). Efficacy was assessed using VITA shade scores and safety evaluations were performed including the examination of plaque index (PI), bleeding index (BOP), gingival recession and dentin hypersensitivity. Statistical analysis was performed to determine the mean change from baseline.

RESULTS: The new whitening gel containing 5.9% hydrogen peroxide was significantly effective in lightening tooth shade. After only 2 weeks, patients enrolled in the study exhibited an overall mean 4.48-shade improvement from baseline, which was significantly greater than placebo group and far exceeded the ADA minimum requirements to claim "clinical efficacy". In the new Colgate Simply White Clear Whitening Gel group, periodontal health (PI and BOP) improved with time overall. Moreover, dentin hypersensitivity did not significantly increase, and all treatments were generally well tolerated.
CLINICAL SIGNIFICANCE: The new Colgate Simply White whitening gel containing 5.9% hydrogen peroxide allowed consistent bleaching using minimal contact time, without adversely impacting overall tolerability.

Randomized clinical trial comparing overnight use of two self-directed peroxide tooth whiteners.

PURPOSE: To directly compare tooth color change and spatial uniformity of two brush-applied, peroxide-based overnight tooth whiteners in a 2-week randomized clinical trial.

METHODS: 57 adult volunteers were randomly assigned to Crest Night Effects, a 19% sodium percarbonate system packaged in unit dose sachets that when applied, dries to form an adherent film, or Colgate Simply White Night, a paint-on liquid in an applicator bottle at a concentration of 8.7% hydrogen peroxide. Both groups applied their assigned gel on the facial surfaces of the six maxillary anterior teeth for 14 nights. Efficacy was measured objectively as change in L*a*b* tooth color from standard digital images of maxillary teeth, while safety was evaluated by clinical examination and interview.

RESULTS: After 14 nights treatment, adjusted mean (SE) change in yellowness (delta b*) was -0.95 (0.092) for the 19% sodium percarbonate film and -0.17 (0.096) for the 8.7% hydrogen peroxide gel, with these groups differing statistically (P < 0.0001). Other individual and composite color parameters also demonstrated significantly greater whitening for the 19% sodium percarbonate film compared to the 8.7% hydrogen peroxide gel after 14 nights use. Only the 19% sodium percarbonate film exhibited significant (P< 0.0001) proximal color improvement (delta b*) after 2 weeks, approximately 98% of that seen on the body of the tooth, providing evidence of proximal bleaching and uniform spatial whitening following use of this barrier-free system. Both products were well-tolerated, with no subjects discontinuing treatment early due to a causal adverse event.

hope I'm not boring you now... :-/

Safety evaluation of a novel whitening gel, containing 6% hydrogen peroxide and a commercially available whitening gel containing 18% carbamide peroxide in an exaggerated use clinical study.

OBJECTIVES: The aim of this study was to compare the effect on oral soft tissue of a self-applied tooth whitening gel containing 6% hydrogen peroxide (Xtra White) with a marketed paint-on whitening gel containing 18% carbamide peroxide (Colgate Simply White) after 2-weeks of using products four times daily.

METHODS: A 2-week, examiner-blind, stratified, parallel design clinical trial was conducted. Twenty subjects were divided into two groups, balanced according to age and gender. Subjects followed a 2-week, twice-daily regimen of brushing with standard fluoride toothpaste and applied gel product to facial aspects of six upper and six lower incisors/canines, twice in succession with 30 min between applications. Soft tissue examinations were performed on Day 1, before the first application of the test products, and on Day 2, 5, 8 and 15.

RESULTS: During the 2-week treatment period, twelve adverse reactions were recorded as potentially attributable to the study products, evenly split between the two test groups. All reports were mild in symptoms and resolved without the need of medical intervention. None of the subjects experiencing an adverse event requested to be withdrawn from the study.

CONCLUSIONS: Under the exaggerated use conditions of this test, there was no evidence to suggest that either of the whitening gels produced irritation that was building or developing during the course of the study. It is concluded that both products are safe for their intended use.

There is plenty more on that website http://www.pubmed.com if you search for words like Colgate Simply or Tooth Whitening etc.

Hope that helps ! ;D ;D

Another quick question that perhaps some of the dentists on this thread may be able to help with.

What effects good or bad do at-home or in-surgery whitening procedures have on crowns?

Is one method or type of "bleaching" agent better than another for crowns?

Do they not whiten them at all, or make then go a different or funny colour or whiten them happily just like natural teeth?

I would appreciate some info and advice on this before shelling out hard earned cash on either.

Thanks ;D ;D

I too am interested in the effect on crowns. Are the dentists on this forum able to shed any light on this?

Thanks,

Chris

A big thanks for the tip on Crest whitening strips. I bought the Crest Premium strips from US EBay and I am so impressed I just bought more for the family. The exchange rate is quite good at the moment - I paid £12 including delivery and must say they worked a treat. I am not Ross Geller by any means but there has been a noticeable difference.

Thx again!

[flash=200,200][/flash]Teeth Whitening... On the subject of teeth whitening I have just used a product that my local sun tanning shop sells.. It's cheap it works.. all I had to do is apply it to my teeth and relax under the sun bed and I noticed a difference the first time I used it.. After reading all the other stories of complying to the Cosmetic Regulations I called the salon and they said that it does comply to the regulations.. So if anyone wants to know about it let me know.. ;D [email][/email]

Great

Tetracycline it was! Caffeine addiction does not help either! Half a lifetime of tight-lipped smiling has left me practically wrinkle-free, but has done little for my popularity at work and play! I may just try the bleaching, before I have the whole lot veneered!
