Syringe delivery tip including an enlarged flocked wing element adjacent a distal delivery end
Abstract:
A delivery tip for dispensing a high viscosity composition (e.g., a fluoride varnish composition) includes a tip body and a fiber flocked enlarged wing element disposed near a distal delivery end of the tip body. The tip body includes a passageway extending between an inlet orifice at a proximal end and a delivery orifice at the distal delivery end. A ratio of the width of the enlarged wing element to an inside diameter of the delivery orifice is at least about 5:1, which controls flow of the fluoride varnish composition through the delivery orifice while also providing for a wide application width for easily brushing the composition onto a patient's tooth.
