ABSTRACT:
A dental nozzle, cartridge, capsule or container having a porous or foam flow through applicator connected at the discharge end thereof; and having a body portion containing or receiving a low viscosity dental material. In one form, a displaceable plunger or piston is disposed within the body portion to extrude the dental material through the discharge orifice and attached flow through applicator. The foam or porous applicator may be connected to the discharge end at the time of manufacture as by molding, or by mechanically connecting or by adhering the same to the discharge orifice as part of the assembly process. The flow through applicator may be made in a variety of shapes to provide improved and controlled application of a low viscosity dental material to a dental site. Additionally, the porosity of the porous or foam material may be matched to the viscosity of the dental material to control the flow of dental material therethrough.
