# Preventio Hub

> Independent, anonymous publication on dental prophylaxis for dental professionals in the United States and Canada: air polishing and ultrasonic equipment, prophylaxis powders, clinical techniques and peer-reviewed evidence.

Preventio Hub is independent in its editorial content. We may receive compensation from suppliers when a quote request leads to a sale; this never changes what we write. Its editorial rule is that every specification and clinical claim must trace to a public source (manufacturer documentation, a distributor listing or a peer-reviewed study); where a figure is not published, pages say so. Prices are on request: the site does not publish prices. Brands are listed alphabetically. Articles are published under the collective byline "Preventio Hub", without individual author names. Pages rewritten under this standard carry a dated update or correction note.
