The Hukuba hyG Ionic Toothbrush is a safe and effective oral cleansing device when used unsupervised on a regular basis in the removal of human dental plaque.
PLAQUE REMOVAL EFFECTIVENESS OF hyG TOOTHBRUSH EMPLOYING THE
LITHIUM BATTERYResults:
- Plaque removal. Estimates according to O'Leary's PCR (p<0.01) and PHP (p<0.05), the efficacies of the lithium battery toothbrush and the control toothbrush differed significantly.
- Improvements in gingivitis. In terms of the PMA index (p<0.05), the lithium battery toothbrush produced better results than the control toothbrush.
- Changes in bacterial levels. No changes in oral microorganism levels were observed after the experimental period, no matter which kind of toothbrush was used.
- Plaque accumulation compared in terms of caries risk group. In the Low risk group, no significant differences were observed between the toothbrushes before and after the experimental period. In the High risk groups, however, the lithium battery toothbrush removed bacterial plaque more effectively.

EFFECTIVENESS OF AN ELECTRONIC TOOTHBRUSH (hyG) ON GINGIVITIS
...Finding suggest that improvements in gingivitis might be expected through charging gingivital tissue electronically in addition to mechanical plaque removal by toothbrush itself.

PILOT STUDY TO EVALUATE AN IONTOPHORETIC TOOTHBRUSH TO REMOVE PLAQUE
Results and conclusions:
Both plaque grading methods revealed a percent difference in favor of the hyG treatment. The six selected tooth surfaces employed in the PHP index support the conclusion that the hyG brush is superior in plaque removal to an ADA accepted brush (Butler Gum #440).

AN EFFECTIVENESS STUDY OF ELECTRONIC TOOTHBRUSH (hyG) IN PLAQUE REMOVAL
The electronic toothbrush (hyG) was much more effective in plaque removal than the ordinary toothbrush in all the subjects...The effectiveness of the electronic toothbrush can be expected even if there are differences in brushing techniques. The most valuable results in this study were seen at the cervical region...the hardest place to clean.
1990 Study, Tokyo Dental College
EFFECT OF IONTOPHORETIC TOOTHBRUSH ON PLAQUE REMOVAL
...All thirteen subjects achieved higher plaque removal with the iontophoretic toothbrush (hyG) than with the ordinary toothbrush with a high statistical significance of P<0.001. The "hard" bristles of the iontophoretic toothbrush (0.28 MM nylon filament) achieved higher plaque removal than the medium hard (0.23 MM) bristles.

THE EFFECTIVENESS OF AN ELECTRO-IONIZING TOOTHBRUSH IN THE CONTROL OF DENTAL HYPERSENSITIVITY
The object of the investigation was to test the value of the 3M Brand Electro-Ionizing Toothbrush in the treatment of dentinal hypersensitivity. Eighty-eight volunteers were divided into three groups, each using different methods: (I) stannous fluoride dentifrice and 3M brush without a battery; (II) stannous fluoride dentifrice and 3M brush with a 1 1/2 volt battery; (III) strontium chloride dentifrice and 3M brush without a battery. The volunteers brushed their teeth for 3 minutes twice a day for 12 weeks using one of the three test agents. The subjects were tested at weeks 0, 2, 4, 8, and 12 by means of a cold water spray quantitated by a temperature probe. All three groups experienced improvement and by week 12 groups II and III displayed much less sensitivity than did group I. At the end of 12 weeks the subjects were questioned as to benefit of treatment. The questionaire revealed that stannous with the ionizing brush provided significantly greater relief than did the stannous fluoride alone.

EFFECT OF IONTOPHORETIC TOOTHBRUSH ON CERVICAL HYPERSENSITIVITY
The following results were obtained:
-
- The clinical effect (reduced hypersensitivity) of the iontophoretic was significantly different from the placebo group after two weeks (P<0.01) and it was a highly significant difference (P<0.001) after six weeks. In the active group the reduction in sensitivity after six weeks was shown to be 60.6% and in the placebo group 25.4%.
-
- 50.1% of the initially sensitive teeth had lost all sensitivity after six weeks.
-
- No side effects of this iontophoretic toothbrush were observed.
On the basis of the above facts, it is concluded that an iontophoretic toothbrush used with a fluoride dentifrice is highly effective in cervical hypersensitivity. Accordingly, the use of an iontophoretic toothbrush is a simple and available method for home dental care.
...iontophoresis is indeed highly effective.
...This technique has no equal in relieving dental hypersensitivity.

HYPERSENSITIVITY CONTROLLED BY IONTOPHORESIS
Collins found an 87.5% decrease in hypersensitivity in his active group and a 22.8% decrease in the control group.
Producing iontophoresis of fluorides in daily oral hygiene by the use of an electronically charged toothbrush could open the way to even greater benefits from the use of fluorides in dentistry. Since it has been shown previously that topical fluoride has a certain, although limited, effectiveness in alleviating hypersensitivity, the increase of effectiveness under the influence of an electronically charged toothbrush is suggestive evidence that this device increases the deposition of fluoride on, or within, the tooth.
From available evidence it seems unlikely that fluoride would reach the pulp in sufficient quantities to have any adverse effect.
. . . pathological studies of tooth pulps after iontophoresis of fluoride have been described in two recent reports.
. . . all pulps were regenerated completely histologically.
. . . histological examinations revealed no evidence of any permanent pulp damage.
. . . enamel pore wall is negatively charged . . . facilitating the penetration of positively charged ions (cations) and resisting the penetration of negatively charged ions (anions). Thus, the penetration of fluoride, which is the most negative ion normally is resisted by the enamel.
The fact that similar charges repel and opposites attract . . . if the negative charge of the enamel is temporarily reversed to positive the amount and depth of penetration of negative ions (fluorine) is facilitated.
. . . a majority of subjects in the active group reported a new feeling of cleanliness in their mouth, similar to having their teeth cleaned by a dental hygienist.
. . . various other oral processes may be affected, such as the deposit of calculus.
. . . use of an iontophoretic toothbrush resulted in the removal of protein matrix and free calcium adhering around the teeth, and the removal of putrefied matter coming from inflammation.
. . . no undesirable side effects were noted after two years of continued routine use.

DESENSITIZATION OF HYPERSENSITIVE TEETH
The teeth can be charged with a positive electrical potential by means of a battery while fluoride is being applied. Since fluorine is the most negative of all ions, iontophoresis may be employed as a practical method to increase penetration or deposition of fluoride in the dental enamel and dentine.
. . . an (electrical) potential low enough to be considered safe for continued use.
. . . electrical potential of the magnitude delivered by the iontophoretic toothbrush appears to be safe for daily use. Lefkowitz reported using a potential five hundred times greater . . . than supplied by the brush without damage to the pulp. There was no apparent damage to the soft or hard tissue of the oral cavity.
Home care . . an affective treatment by simply brushing teeth with a fluoride dentifrice and an iontophoretic toothbrush.
. . . an exceedingly potent therapeutic means of relieving hypersensitivity.

What People are saying about the HyG Toothbrush!
As a dentist, I've noticed quite a diffrence in my oral hygiene with the hyG. My last two cleanings were fifteen minutes long, with no tartar present. I have found that my teeth feel cleaner and my mouth more fresh.

I have been using the hyG toothbrush for over a year. As a periodontist, I know what a plaque free tooth should feel and look like. I have found the difficult to reach molar areas are much cleaner and my mouth tastes so much better since using the iontophoretic brush. I would gladly recommend it to all my patients and friends.

I conducted a mini-research project though my office and found the response in general, to be positve with only one person feeling indifferent. Teeth feeling cleaner was the normal response. A colleague's wife reported her teeth never felt cleaner and refuses to use anything else. From a clinical standpoint, less plaque was evident, especially in the hard to clean places...My daughter appreciated its effectiveness during the two years she wore braces, it made the difficult job of cleaning around brackets much easier.
One patient, who has a history of bad breath resulting from smoking, coffee and questionable homecare, had dramatic improvement within just days. This toothbrush is especially applicable for those patients who have a difficult time cleaning their teeth (i.e. the elderly, people with braces, the handicapped, or those just suffering from lack of motivation).

When I recently went to the dentist for a checkup, he congratulated me on how clean my teeth were, with no plaque or cavities. I'm a 95 year old woman, so I appreciate a toothbrush that helps me save money on dental bills!

I want to thank you for allowing me to be part of the testing of the hyG toothbrush. I definitely feel a cleaner taste in my mouth after brushing.....I have a terrible plaque problem and am eager to find an alternative to surgery, which I have had twice unsuccessfully.
I use the battery tester once a week to prove to myself that it is still working, It gives me a heightened sense of security...
Sue Corb

For the past twenty-two months I have been using this strange toothbrush....Prior to that time, my dentist was concerned that in the very near future I would need to have repair done to my gums. I am very happy to report that my last visit to the dentist was good . The plaque build up was minimal even though I had not seen a dentist in nearly two years...I can also tell you that since I have been using this new toothbrush, I have no bleeding while brushing...
My husband recently began using the hyG and he is already beginning to notice the difference in his teeth and gums. We both feel that it leaves our mouths feeling more refreshed...

I am a smoker and since I've started using the hyG electronic toothbrush, I've noticed that my breath stays fresher longer. My teeth feel clean and smooth, like I've just come from the dentist.
The idea of having several brush heads included is wonderful. Now I don't have to worry about running to the store when the old one wears out. I just pop on a new one! I recommend that anyone who hasn't tried a hyG do so today!
T. Bennetts

The timing on my experimental use of the hyG was excellent. I had fallen and experienced the loss of two incisors and tearing of the tissue in the roof of my mouth. My dentist explained the importance of massaging the damaged tissue area. I immediately started using the hyG and had rapid and excellent healing....At the same time, I was experiencing a clean smooth feeling throughout my mouth.
As a former dental assistant, I would highly recommend this product to anyone who wants a clean, fresh mouth.

I have always had regular dental cleanings and the closer to the big 50th birthday, the worse the news becomes!... My mother had more than $12,000 in dental work and I figured genetically, I may be in for the same problems... Usually I endure the torture of scraping and scaling but atfer 5 months of using the hyG brush my last visit to the dentist was almost bloodless! The hygienist was amazed! If this hyG can save me $12,000 in dental bills, I am a believer.
Jeanette Rae
Clearwater, Florida
I have been using the hyG toothbrush for about a month and a half. The following are my observations and opinions of the product:
My teeth appear whiter and feel cleaner since using the hyG. Being a smoker, this is greatly appreciated. Also, before using the hyG, I had some hot/cold sensitivity in a couple of molars. I have noticed that this is reduced. I am looking forward to my next check up to see if my dental hygienist notices any change.
Mary Jane Mueller

This letter is to let you know how much I enjoy brushing with the hyG toothbrush. It works so well it makes my teeth feel so clean, like I just went to the dentist. I have been using it for only a couple of weeks but, I can already tell the difference. I will continue to use it for sure! Thank you for introducing this great product to me.
