The pharmacy's dental lineup is becoming as dazzling as the supermarket's grain aisle.
50 dental holes, 1 serving mouthwash and dozens of mechanical equipment for shoppers eager for sweetness
Smell breathing, no tooth decay, and most importantly, no tartar or tartar.
Is any of them really working? Or is it that consumers are induced to produce a false sense of security that may end up with teeth falling off at the end?
An assessment of the $2 billion oral care market at the Greater New York dental conference last month concluded that most of the new over-studythe-
The design of the counter product is too bad. they can't prove anything.
Better research has shown that most products are ineffective or meaningless for oral health.
Karen A made an analysis.
Baker, assistant professor of oral and facial surgery at the University of Iowa.
Most people will do better with two, she said.
Use regular toothbrushes every day, and of course, do professional cleaning every three to six months.
According to experts from the research evidence, although many new products have certain effects in controlling dental plaque, their usefulness in preventing periodontal diseases remains to be proved.
Professor Baker's analysis of the literature includes the following: 90% of toothpaste currently on the market is fluoride.
This is good because fluoride in toothpaste helps to prevent tooth decay.
As for the statement about "Tartar control", the validity of newly formulated or repackaged products such as Dentagard, close-up, Viadent and Crest and Colgate Tartar Control remains
"When patients are brought in and get special instructions and new materials, you will expect improvements in any product," said Professor Baker . ".
Reduce tartar, she added (
Hardened sediment on teeth)
Unlike plaque reduction, plaque may contain bacteria and cause periodontal disease.
Although it is desirable to reduce plaque, it is not synonymous with reducing gum disease.
In addition, she said that toothpaste can control tartar, which is more cosmetic value than health value, because it does not remove deposits left between the gum line and the teeth.
Professor Baker warned that some products that appear to have the American Dental Association's Approved Seal actually have signs that only look like official seals.
Others with real seals are only approved as cave warriors, not to prevent tartar or tartar.

Studies have shown that fighting toothpaste is like prevention with zinc compounds.
However, she said that there is a potential risk as zinc in toothpaste can run out of calcium in the teeth.
The dentist is also concerned about the wear and tear of toothpaste, especially for those with a sunken gums, which exposes the soft layer on the root.
Dry tooth holes and toothpaste designed to whiten the teeth of smokers are the roughest.
Professor Baker said that the least grinding is Colgate with MFP, and the slurry of baking soda and water.
Toothpaste developed for sensitive teeth should be used at least twice a day for a month to establish effectiveness, she said.

Research has shown that toothbrushes are still the most effective dental plaque and rotten fighter jets.
To clean the teeth and avoid damaging the gums, the dentist recommends using a soft nylon bristles with round ends.
Of the 58 brands tested under an electron microscope, only 5 have the most desirable rigid hair structure: Sensodyne, Reach, Butler, Jordan, and Lactona.
As for the shape, the curved handle does not have any advantage, but the curved head may help to clean the tongue side of the teeth.
The brush head should be round and small enough to reach the last tooth.
Research has shown that there is no special advantage in using an electric toothbrush.
However, for those who lack the dexterity to remove patches with a regular brush, the $99 Interplak brush is described as useful.
While data supporting the additional benefits of dental floss use remains to be collected, dental experts agree that the use of dental clearance equipment helps to remove dental floss from places where toothbrushes cannot easily reach.

However, no one is considered superior to dental floss.

The struggle with mouthwash masks poor research into the effectiveness of its claims.
Professor Baker pointed out that few studies last long enough for a meaningful result, which takes about two months of daily use, and many studies use unrealistic test conditions.
In a study of Viadent, participants washed five times a day, far more than the number of times most people washed one or two.
In addition, the decrease in plaque, even with five rinses per day, is not necessarily enough to prevent the disease, Professor Baker said.
Viadent contains an antibacterial plant derivative called sanguine.
In a study on Plax, the subjects performed 16 to 18 hours without oral hygiene, and the advertisement claimed that Plax was more effective than brushing a person's dental plaque and then rinsed with Plax, brush your teeth, but only 15 seconds.
Professor Baker said that the average American brush is 33 to 65 seconds. if the two groups are longer, the results may be different.
As for the smooth feeling in the mouth after rinsing with Plax, she said, it is mainly glycerin, not any detergent.
Both Viadent and Plax may be helpful in oral care, but their clinical usefulness in controlling gum disease remains to be demonstrated.
Plax contains the same antibacterial agent benzoate sodium as in the Lyst Forest recently approved by. D. A.

It leaves a coating on the surface of the mouth for 10 to 12 hours.
People with chronic periodontal disease may ask the dentist about the product, which reduces the plaque by 61% and also reduces signs of gum disease.
Fluoride oral flushing, while helping to prevent decay, has not yet been identified as a notable dental plaque warrior.
Professor Baker says people who don't brush their teeth often or use floss often use this rinse.
She stressed that no mouthwash can replace diligent brushing, floss cleaning and regular professional cleaning.
As for the well-received technique of using baking soda toothpaste and peroxide mouthwash, Professor Baker noted that this method has not improved significantly compared to regular brushing and fluoride toothpaste.
