Dental material compositions for cleansing and removal of anionic contaminants from substrates and their methods of use

An applicator for a syringe is provided that includes a hub configured to be disposed at least partially within a nozzle of the syringe and defining a fluid passage therethrough, with one or barbs on the hub that frictionally and sealingly engage an interior of the nozzle in a manner minimizing void space associated with waste of deliverable material, and an applicator tip extending distally from the hub. The barb(s) may have varying diameters in order to enable the applicator to be engaged and utilized with syringes having different diameter nozzles. Further the fluid passage through the hub and applicator tip is dimensioned to minimize the volume of material that is retained within the applicator after use, thereby increasing the volume of material that can dispensed from the syringe for use in a procedure or procedures and minimize waste.
