HCDG's Products have been clinical proven in over 120 studies world wide.
The most recent studies have shown the tremendous
efficacy of the Broxo® PerioSonic toothbrush as both a highly efficient
mechanical brush AND an unequalled sonic
brush. The Studies demonstrate:- Unsurpassed plaque removal by the PerioBrush and
PerioSystem brushing systems.
- Unsurpassed sonic cleaning capabilities that allow
the PerioBrush to remove plaque even beyond the reach of the toothbrush bristles.
- Additional plaque removal benefits of the
patented fractionated microjet irrigator.
- Outstanding safety of both the PerioBrush and PerioSystem
when compared to competitive products.
- Overall superiority of the microfractionated irrigator when compared to
WaterPik and other mono-jet irrigators.
- Overall superiority of the PerioBrush and PerioSystem brushing action when
compared to its major competitors.
- Superior interproximal cleansing ability of the micro-fractionated irrigator.
- The effectiveness of the brush/irrigator and brush alone at reducing
pocket depths, gingival bleeding and gingival inflammation.
- The ability of the products to provide increased capillary circulation,
keratinization and overall tissue massage.
- The superiority of the micro-fractionated irrigator in delivering
anti-microbial agents; reducing side effects while providing optimal efficacy.
The Broxo PerioBrush
produces sonic cleaning properties equal to or superior to the current market
leaders (Sensonic & Sonicare).Documentation Cobb, Charles M. “ Evaluation of the ability of the Woog Periodontal Brush
to remove dental prlaque bacteria beyond the tips of the bristles: An in-vivo
study”., University of Missouri-Kansas City, 1996 Trefny, John U., “Shear Stress and acoustic pressure measurements for
the PerioBrush”. Department of Physics Colorado School of Mines, 1995 Trefny, John U., “Shear Stress and acoustic pressure follow-up study”.
Department of Physics Colorado School of Mines, 1996 The first Trefny study, using a variety of measurement of brush tip velocity,
acoustic pressure and shearing stress produced by the PerioBrush bristles, clearly
demonstated that the oscillating brushing action of the PerioBrush produces
signicant levels of acoustic pressure and shear strength beyong the reach of
the tooth brush bristle. These levels were comparable to those produced by the
Sensonic and Sonicare brushes. The second Trefny study using a protocol design which placed a measuring probe
2mm into the interdental space, demonstrated that the brushing action of the
PerioBrush in the presence of water and bacteria produced a sufficient medium
to allow significant transmission of these acoustic forces to the interdental
areas. The Cobb study, using the same study protocols designed by Slots (using the
Sensonic brush) and Engel (using the Sonicare brush) clear demonstrates that
the acoustic forces produced by the oscillating motion of the PerioBrush effectively
removes bacterial plaque without direct contact with the plaque. The Broxo*
home care products have been clinically proven to effectively reduce gingival
inflammation, bleeding and pocket depths.  Documentation Robertson, P. et al., "A Study of the Effect of Four Oral Hygiene Methods

ability of the PerioBrush Brush and Irrigator to significantly reduce gingival
inflammation, bleeding and pocket depths. The study showed that these reductions
were equal to or greater than the results obtained with ideal, continuously
monitored traditional home care methods. Length of study and number of patients
gives clear indication of the arrest of periodontal disease when Broxo* devices
are used. The study also document patient compliance levels superior to traditional
oral hygiene methods. Patient surveys indicated 100% of users of PerioBrush
said they planned to continue using the product after the completion of the
study. All subjects using PerioBrush completed diaries during the study compared
to 85% of those in the manual brushing group. The Lange study documents significant improvements in bleeding and gingival
indices when using PerioSystem's irrigator with and without anti-microbial agents.
The study also describes significant reduction of gingival inflammation. The PerioBrush
and PerioSystem provide unsurpassed plaque removal.  Documentation Yankell, S., Comparison of Plaque Removal and Safety of PerioBrush (Broxo Total)

IADR, 1973. Studies clearly demonstrate effectiveness of products in removing plaque. Of
interest in Yankell study is that plaque removal was accomplished without dentifrice,
as recommended by Interplak. Despite this the PerioBrush alone equalled or bettered
the plaque removal of the Interplak brush. Researchers believe that if study
had been performed using manufacturers recommendations (Dentifrice with PerioBrush,
none with Interplak) that the Periobrush would have shown significant plaque
removal advantage. Additional decay protection would also be gained by the use
of fluoride containing dentifrice. Additional plaque removal could also have
been produced by the use of thePerioSystem irrigator. The Robertson study compared the PerioBrush, with and without irrigation to
traditional manual oral hygiene techniques. These techniques were performed
under ideal conditions with extensive patient instruction and continuous patient
reinforcement of brushing techniques. Other study has shown that the average
individual does not perform ideal home care (5-7 minutes) and infact may spend
less than one minute brushing (Emling, Robert et. al, "A comparison of
Estimated vs. Actual Brushing Time", U. of Pennsylvania, 1982.) The PerioBrush
equaled or bettered plaque removal efforts of other methods even under these
skewed circumstances. The Broxo* home dental
care products provide outstanding Clinical Safety.  Documentation Yankell, S., "Comparison of Plaque Removal and Safety of PerioBrush (Broxo

University of Geneva, 1971. The Yankell study directly compared PerioBrushBrush to the Interplak in a cross-over
study of ten patients. Photographs were taken following brushing with each device.
Both trained and untrained observers detected signs of tissue trauma in the
Interplak subjects with only nominal trauma signs observed when patients used
the PerioBrush Robertson study showed no indication of tissue trauma in any patients using
either the brush or irrigator of the PerioBrush. Both Manhold and Ferrrazzini
documented the safety in regard to tissue penetration and tissue hemmorhage
of the micro fractionated irrigator. In both studies the micro-fractionated
irrigator proved superior to the mono-jet irrigator of Water-Pik and others.
The micro-fractionated
irrigator (PerioSystem) has been clinically proven to be more effective for
removing loosened plaque, and for interproximal cleansing than any irrigating
device available. The irrigator and brush combination has been proven to provide
significant advantages in loosened plaque removal and removal of debris from
retention areas, compared to brushing alone. Documentation Yankell, S.L. et al, "Pilot Study to Evaluate Pulse Oral Irrigation Devices

than monojet irrigator. Lange documented that an additional 41% of plaque was removed when using the
irrigator following brushing. Also documented significant improvements in tissue
health. Lang and Raber stated that groups using the micro fractionated irrigators showed
superior mean plaque scores than did those using the monojet irrigator. In addition,
they documented that the microfractionated irrigator, without the use of anti-microbials,
helped prevent the development of gingivitis. The micro-fractionated
irrigator has been clinically proven to be the most effective and safest method
available for delivery of oral anti-microbial agents. Documentation Lange, D.E., Rager, H., Plagman, H., and Bauman C., "Investigation on

in delivering the optimal dosage of chlorhexidine to the oral cavity, particularly
interproximal areas. Dosage requirements were one half that required by a monojet
irrigator to achieve optimal results. The PerioBrush and
micro-fractionate irrigator provide effective tissue stimulation and increase
in gingival circulation. Documentation Schwermer, H., " The Effectiveness of water irrigating devices and a Toothbrush

not necessarily provide tissue health and that professional prophylaxis followed
by optimal patient home care is the ideal method for maintaining periodontal
health.  Braatz, L. et al, "Antimicrobial irrigation of deep pockets to supplement

significantly contributes to the presence or absence of periodontal disease.
