ABSTRACT:
A dental syringe and disposable capsule for dispensing a dental material wherein the capsule includes a reservoir portion containing a predetermined amount of material to be dispensed, and which reservoir is connected in communication with a discharge tip. Connected to the end of the tip and projecting therethrough is a needle cannula through which the material is ejected. A displaceable piston, which seals the material within the reservoir portion, is provided to force the material through the cannula when displaced within the reservoir portion. The arrangement is such that the cannula connection within the tip end permits the cannula to be rotatably mounted relative to the tip while maintaining a seal between the tip and the cannula.
