A Clinical Study to Evaluate the Effectiveness of an Ionic Toothbrush in the Removal of Dental Plaque
R.L.Van Swol, D.E.Van Scotter, A.R.Dentino, J.J.Pucher
A clinical study at Marquette University School of Dentistry has demonstrated the effectiveness of a manual hyG
Ionic Toothbrush in unsupervised brushing for six months. The double-blind study had 64 adult subjects ranging in age from 18 to 67 years. They were divided into two groups: Group 1, the test group, had 30 subjects using the hyG Ionic Toothbrush with an active battery. The control group, Group 2, had 34 subjects using the hyG Ionic Toothbrush without an active battery.
RESULTS
Plaque scores were determined at baseline, three and six months using the Turesky-Gilmore-Glickman Index. Likewise, gingival indices were determined using the Loe Silness Gingival Inflammation Index.
Group 1 (test) showed a 36.17% reduction in plaque from baseline to month six, compared to only 18.56% for the control group.
Improvement in gingival health was 51.87% for the test group and 30.18% for the control group. The average changes in both plaque and gingival indices were statistically significant for the test group using the hyG ionic toothbrush with an active battery.
The toothbrushes were identical except for the presence of the active battery. The ionic action from the three (3) volt lithium battery produced the significant plaque and gingival changes observed.
The 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
Results:
1. 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.
2. Improvements in gingivitis. In terms of the PMA index (p<0.05), the lithium battery toothbrush produced better results than the control toothbrush.
3. Changes in bacterial levels. No changes in oral microorganism levels were observed after the experimental period, no matter which kind of toothbrush was used.
4. 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.

EFFECT OF IONTOPHORETIC TOOTHBRUSH ON CERVICAL HYPERSENSITIVITY*
The following results were obtained:
1. 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%.
2. 50.1% of the initially sensitive teeth had lost all sensitivity after six weeks.
3. 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.
