The Robertson study, conducted on 100 patients over six months, documents the ability of the BROXO ® brush and irrigator to significantly reduce gingival inflammation, bleeding and pocket depth. The study showed that these reductions were equal to or greater than results achieved with ideal, continuously monitored traditional home care methods. The duration of the study and the number of patients give a clear indication of the cessation of periodontal disease when using Woog appliances. The study also documents higher levels of patient compliance with traditional oral hygiene methods. Patient surveys indicated that 100% of BROXO ® brush/irrigator users said they planned to continue using the product after the study ended. All subjects using BROXO ® completed a diary 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 microfractionated irrigator with and without antimicrobial agents. The study also describes a significant reduction in gingival inflammation.


The ability of the products to increase capillary blood flow, keratinization and overall tissue massage.

Additionally, epidemiologic studies are available to document the existence of cultures with significant plaque formation without the presence of periodontal disease.

These data support the likelihood that some factors other than plaque contribute significantly to the presence or absence of periodontal disease. Dr. Woog's 1954 theories of "biting" and tissue massage seem extremely viable in this light.
