Abstract: The hydrocolloid injection system which utilizes a dispensing syringe as the vial within which the hydrocolloid impression material is shipped and stored prior to usage. The syringe includes a transparent barrel within which the hydrocolloid material is located. A plunger is slidingly mounted within the barrel which is to function to cause the hydrocolloid material to flow from the barrel through an outlet opening. The plunger forms an airtight and watertight seal with respect to the barrel with also a cap being located about the outlet opening of the barrel also forming an airtight and watertight seal. The barrel, plunger and cap can all be located within boiling water with no fear of the water itself actually coming into contact with the hydrocolloid impression material. During usage, the cap will be removed and a nozzle assembly mounted in conjunction with the barrel to facilitate depositing of the hydrocolloid impression material at its desired location.
