An nozzle for storage and application of liquid dental material, such as primer or adhesive, to a preparation site at a patient's teeth, gums or mouth. The nozzle includes a hollow nozzle for containing the liquid dental material. The hollow nozzle can include a flocked, open tip through which the liquid dental material is dispensed. The nozzle also includes a storage block having a plurality of cavities formed therein. A plurality of hollow nozzles can be inserted into the cavities to form substantially air-tight seals between the open tips of the hollow nozzles and the exterior of the cavities. An end of the hollow nozzles opposite from the open tip and exposed above the block includes a breakable seal. Accordingly, the hollow nozzles can be stored in the block for an extended period of time. To apply the liquid dental material to a preparation site, an applicator can be attached to the end of the hollow nozzle exposed above the block. The applicator is adapted to break the breakable seal and force the liquid dental material from the interior of the hollow nozzle through the open tip and onto an application site.

[What is claimed is:] [25.]a plurality of nozzles having therein a quantity of liquid material and having a means for attachment to a driver so that the liquid material can be dispensed and applied to a preparation site, each nozzle having a passage defined from a sealed inlet at one end thereof to a tip on another end thereof, the inlet providing access when its seal is opened to the passage within the nozzle for a driver device when attached to a driver, the passage sized for containing the predetermined quantity of liquid material, and the outlet permitting dispensing of liquid material from the passage, each nozzle also having a shoulder between their inlet and outlet ends that extends from each nozzle;a storage block having an external surface with plural openings that provide access to a plurality of cavities that extend within a depth of the storage block within which a plurality of the nozzles are provided with their respective attachment means accessible for connection to a driver without first removing the nozzles from the storage block, said nozzles being unattached to a driver and removably supported within the cavities as positioned by the shoulder of each unattached nozzle that limits an inward position of each unattached nozzle within a cavity of the storage block by abutment of the shoulder of an unattached nozzle with a surface of the storage block.
