Fresh breath. White teeth. Balanced oral health.

Evora Plus™ mints for adults and EvoraKids™ chews for children add good bacteria and a low level of hydrogen peroxide to the oral environment for fresher breath, a healthier mouth, and whiter teeth. Twenty-five years of research went into the making of this innovative product, developed by Jeffrey Hillman, DMD, PhD.

The company’s website states: “Within 30 days of using EvoraPlus twice daily, the natural healthy oral balance of good bacteria will be greatly restored and you will begin to notice a whiter, brighter smile and long-lasting fresh breath.”

How it Works

For some time, scientists have known that probiotics promote good digestive health. Yogurt, a food rich with probiotic power, is often recommended for patients with stomach aches and digestion issues. The same philosophy backs the effectiveness of Evora.

Good oral bacteria “crowd out” bad bacteria to promote a positive balance in the mouth. In addition, by reducing bad bacteria, Evora mints reduce potential for foul breath caused by bad bacteria. Good bacteria actually bond to teeth and gums, and even below the gum line for lasting results. This is unlike traditional mouthwashes that kill all bacteria in the mouth, not just the bad bacteria.

As for teeth whitening, Evora’s by product is a small amount of hydrogen peroxide, which is known to naturally brighten tooth enamel without causing sensitivity or irritation to oral tissues.

Each Evora mint has one calorie, and patients are instructed to use two mints each day for best results. Today, Evora is sold at these retail stores: Albertson’s, A&P, Kerr Drug, Walgreen’s, Sweetbay, Heartland, and Pathmark. Online, consumers can purchase Evora through ActiveForever.com, CVS.com, Drugstore.com, ProHealth.com, Quick2You.com, Swansonvitamins.com, Target.com, and Walgreens.com.

Two companies, Procter & Gamble and Colgate Palmolive, dominate the market for over the counter tooth whitening products. As of 2003, these companies had about 84% of the market. Americans spent about $297 million on home use tooth whitening products during the year ending March 23, 2003. This was an increase of 90% over the prior year’s sales. Each company has introduced additional brands of tooth whitening products for use at home. The names of some of the major brands are provided in Table 1.

Other companies have been entering the home use market. These include Bident, Mentadent, and Rembrandt. The overall market for tooth whitening products grew by 596% between 2000 and 2005; in 2005 there was a decline of 23% because of the introduction of other products.

Overall cosmetic dentistry has surged with growth rates of 12.8% in 2006 and 10.9% in 2007. The demand for bleaching and whitening of teeth has been one of the top requested services. However, the cost of using a dentist has become too high for some people and the result is the growth in over the counter products. With the increases in the older population, the need to look young has become even more important. And having a bright white smile is a major part of “looking young.”

By altering skin tone and tooth brightness on photographs of smiling women, researchers created a way to test how people perceive beauty in regards to tooth enamel color. Seventy dentists and 70 laypeople answered questions about the photos. The findings show that skin color affects the shade that is attractive on teeth.

According to the report:

“Dentists and laypeople did not perceive the brightest tooth shade to be the most attractive, and they did not perceive all skin colors to be equally attractive with bright white teeth. Respondents perceived dark skin with bright white teeth and fair skin with dark teeth as relatively unattractive.”

What’s the point, then? The study’s findings provide reason for manufacturers to tweak home whitening systems and improve future generations of the products.

While other studies have tried and failed to measure enamel loss, this recent study by researchers at The Ohio State University measured enamel reduction to the billionth of a meter using a nanometer scale, rather than in microns, which measure to a millionth of a meter. Enamel loss ranged from 1.2 to 2 nanometers after home teeth whitening was applied. It seems that white strips tend to reduce enamel less than tray methods.

*The five home whitening systems for which results were analyzed in the study were Crest Whitestrips Premium Plus, Crest Whitestrips Supreme, Nite White ACP tray system, Oral B Rembrandt tray system, and Treswhite Opalescence tray system.

A New Approach….Way Out Of The Box Thinking

Hey you guys here is a new twist. I was reading in HEALTH magazine that there is a dentist in Boston who makes “tooth whitening house calls”. Right in your own home he will take impressions of your teeth, make whitening trays and leave you with all you need to brighten your smile without leaving your own kitchen. He even offers to come to your office on your lunch hour to get you on the way to a whiter smile. Pretty different approach, I wonder how many he converts to actual patients in his office or if he even has an office??? He only charges $300.00 for this custom service. Sure sounds like a terrific deal for those too busy to get to our offices.

It is time of the year when in some practices things slow down. I have never really figured out why; maybe because of tax time or maybe it is an after the Holiday lull. There have always been things you can do, chart audits, special discount offers, email reminders of unfinished treatment plans, etc. Well here is a new one. Every existing patient who is being seen in hygiene for re-care take a shade and talk about whitening. Explain to your existing patients on their re-care visit that the “standard of care” in dentistry is changing. That you are now taking a full series of digital photos on all new patients when they enter your office. Get them into an empty chair and get photos on them. These patients of record deserve to see their mouths the same way new patients are seeing their mouths. It opens their eyes to the need to get some the dentistry they having putting off for years done. Give them the opportunity to have their comprehensive exam brought up to “the new standard of care” in your office.

     The mechanism of bleaching is actually attributed in part to the dissolution of enamel rod prisms. Based upon a Brazilian study it has been shown that the carbamide peroxide attacks and totally dissolves isloted groups of enamel rod prisms; thereby exposing the underlying dentin. The whitening that one observes during the bleaching process is actually due to chromatic changes in the dentin more so than in the enamel.

    Now since an open avenue exists between the facial surface of the tooth and the surface of the dentin, the potential for POS can occur. As both patient and clinician recognize, the teeth undergoing bleaching can experience considerable pain upon the introduction of cold liquids.

    Specifically, the cold water us transfered through the open channels (previously occupied by the enamel rod prisms) contacting the exposedodontoblastic processes. These odontoblastic processes are then subjected to a reduction in pressure which according to Brannstromm (1972) thereby creating pain. This pain can be quite acute. Incidentally, the dissolution of enamel rods has been demonstrated  using scanning electron microscopy (SEM). Addional numerous other studies have demonstrate that bleaching reduces the microhardness of the enamel surface. Over a period of time the enamel fortunately remineralizes and the hardnes goes back up. Unfortunately some studies  have demonstrated that the microhardness and remineralization may not necessarily return to the orginal pre-bleached state.

    Now that the mechanism of bleaching has been established, better guidelines can be generated for the purpose of enhancing the effectiveness of the bleaching action. This knowledge also is quite helpful in prescribing a regimen for reducing  or eliminating POS. For example, the home bleaching procedure can be coupled with the application of desensitizing agents such as GLuma ir Benzylalkonium chloride. Finally, the rate of enamel rod dissolution  and achievement of the bleaching effect is related to concentration of the peroxide as well as the time of application.

This is a tremendous tool to evaluate shades for indirect, direct, and bleaching shades.  It is quick and easy.  Worthy of a look at the next dental meeting or on the web at www.vident.com.  Just under $4000.
