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.

[ What is claimed and desired to be secured by United States Letters Patent is:] [1.] A delivery tip for use in combination with a delivery device such as a syringe, comprising a reservoir means for holding a quantity of a dental composition for restorative or reconstructive dental procedures and a means for controlled dispensing of the dental composition from the reservoir means and through the delivery tip in order to apply in a precise, controlled fashion the dental composition to a small area such as a relatively small region of a tooth surface that is to be restored or reconstructed, the delivery tip comprising:(a) a tubular member having a proximal end and a tubular distal end, the tubular member having a passageway extending from an inlet orifice at the proximal end to an outlet orifice with a distal rim at the tubular distal end, the tubular distal end being of a size and being configured for precise, controlled delivery of the fluid, the tubular distal end having an outer periphery surface located near said outlet orifice;(b) coupling means on the proximal end for adapting said tubular member for releasable attachment to a delivery device; and(c) a plurality of fibrous bristles disposed on and surrounding the outer surface and distal rim of the outlet orifice such that said bristles permit a free flow of the fluid out of said outlet orifice without any substantial interference from said bristles.
