Dri-Angle are a unique replacement and a decided improvement on the cotton roll in the parotid area. The Dri-Angle covers the parotid or Stensen's duct and effectively restricts the flow of saliva. Dri-Angles come in two types, plain and silver coated. Use the silver coated Dri-Angle for superior saliva control. Silver coating on one side acts as a complete moisture barrier for heavy salivators.
