Clinical studies

Scientifically proven to be the best.

Thanks to the contribution of scientists and to the 168 studies which have successfully tested BROXO® devices, health professionals testify to the superiority of BROXO® line of high performance dental home care products.

Clinical studies have clearly demonstrated that the Broxo home dental care products are the most effective total home care devices available. These studies show:

Superior results in…

The effectiveness of the brush/irrigator and brush alone at reducing gingival inflammation, bleeding and pocket depths.

The Robertson study, performed on 100 patients over six months documents the ability of the BROXO® 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 Woog devices are used. The study also document patient compliance levels superior to traditional oral hygiene methods. Patient surveys indicated 100% of users of BROXO® brush/irrigator said they planned to continue using the product after the completion of the study. All subjects using BROXO® completed diaries during the study compared to 85% of those in the manual brushing group.

The Lange study documents significant improvement in bleeding and gingival indices when using the Micro-fractionated Irrigator with and without anti-microbial agents. The study also describes significant reduction of gingival inflammation.

Unsurpassed plaque removal.

  • Manhold, John H.,Trefny, Cobb, Daniel, "Study of Plaque Removal versus Automatic Brushing", {ADR, 1973.

Studies clearly demonstrate effectiveness of products in removing plaque. Of interest in Yankell study is that plaque removal was accomplished without toothpaste, as recommended by Interplak. Despite this, the BROXO®brush, alone equalled or bettered the plaque removal of the Interplak brush. Researchers believe that if study had been performed using manufactured recommendations (toothpaste with BROXO® toothbrush, none with Interplak) that the BROXO® toothbrush would have shown significant plaque removal advantage. Additional decay protection would also be gained by the use of fluoride containing toothpaste. Additional plaque removal could also have been produced by the use of the Micro-fractionated Irrigator.

The Robertson study compared the BROXO® brush and irrigator, 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 BROXO® brush/irrigator equalled or bettered plaque removal efforts of other methods even under these skewed circumstances.

Additional plaque removal benefits of the patented fractionated microjet irrigator.

The micro-fractionated irrigator (BROXO® irrigator) has been clinically proven to be more effective for removing loosened plaque and for interproximal cleansing than any irrigation 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.

The Yankell study documented significantly greater loosened plaque removal per second than monojet irrigators.

Lange documented that an additional 41% of plaque was removed when using the irrigator following brushing. Also documented significant improvement in tissue health.

showed superior mean plaque scores than did those using the monojet irrigator. In addition, they documented that the micro-fractionated irrigator, without the use of anti-microbials, helped prevent the development of gingivitis.

The Yankell study directly compared BROXO® brush to that of 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 BROXO® brush/irrigator.

Robertson study no indication of tissue trauma in any patients using either the brush or irrigator of the BROXO® brush/irrigator.

Both Manhold and Ferrazzini documented the safety in regard to tissue penetration and tissue hemorrhage of the micro-fractionated irrigator. In both studies the micro-fractionated irrigator proved superior to the monojet irrigator of Water-Pik and other.

The Morris study demonstrated that after 3 weeks of utilization, the BROXO® toothbrush had quantities of fusobacterium nucleatum 1/3162nd that of the Sonicare® DiamondClean and 1/550th that of the Oral-B® ProfessionalCare Smart Series 5000.

Overall superiority of the micro-fractionated irrigator when compared to Water Pik and other mono-jet irrigators.

The BROXO® brush and micro-fractionated irrigator provide effective tissue stimulation and increase in gingival circulation.

Several recent clinical studies indicate that plaque removal alone (through anti-microbial agents) does not necessary provide tissue health and that professional prophylaxis followed by optimal patient home care is the ideal method for maintaining periodontal health.

In addition, epidemiologic studies are available documenting existence of cultures with heavy plaque formation without presence of periodontal disease.

These data support the likelihood that some factors other than dental plaque significantly contributes to the presence or absence of periodontal disease. Dr Woog's 1954 theories of active biting and tissue massage appear extremely viable when viewed in this light.
