ABSTRACT:
A delivery tip for use on a delivery device for applying a dental composition to tooth surfaces includes a tubular member having a proximal end and a distal end. The proximal end of the tubular member is coupled to the delivery device. A plurality of fibrous bristles are disposed on an outer periphery at the distal end of the tubular member. The fibrous bristles can be used in an agitating action to remove entrapped air bubbles from the applied composition such as an impression material. The fibrous bristles on the delivery tip can also be used to coat and spread the composition on tooth surfaces. With the fibrous bristles attached to the outer periphery at the distal end of the delivery tip, the composition can be delivered through the passageway in the tubular member without interference from the bristles.
