DHP Inc.

DHP Inc. manufactures Dri-Angle, a cellulose-based moisture control device designed for dental applications. The Dri-Angle is a non-cotton-roll substitute that covers the parotid (Stensen's) duct to restrict saliva flow, enabling dry-field dentistry for composites, bonding, cementing, and whitening procedures. The product is available in two variants: plain cellulose and silver-coated (for enhanced moisture barrier capability in heavy salivators). Established over 40 years ago and designed by dentist John W. Owen, DDS, the Dri-Angle is marketed as the #1 branded moisture control product in North America, with adoption by over 56,000 dental practitioners. The company distributes samples and products directly to dental offices and through a distributor network. Manufacturing and distribution are based in Niagara Falls, NY.
