Dri-Angles are a comfortable unique replacement and decided improvement over the cotton roll in Moisture control. The Dri-Angle is a thin, absorbant, cellulose triangle contoured to fit inside the cheek, covering the Parotid/Stensons duct, stays in place and does not limit the work area on the external aspect of posterior teeth. Saliva is blocked and absorbed from entering the oral cavity. The silver coated Dri-Angle can be used for superior saliva control. A silver coating on one side acts as a complete moisture barrier for heavy salivators.
