Abstract
A material capsule containing a reactive or caustic dental material and a separately attachable delivery tip having a metal cannula. A material capsule for placement in a syringe contains a reactive or caustic dental material for dispensing through a metal cannula. The material capsule is sealed for storing the caustic or reactive dental material, preventing prolonged contact with or proximity to the metal cannula of a delivery tip. Contact with the reactive or caustic dental material only occurs during actual dispensing. Transition portions facilitate dispensing of viscous material. External grips facilitate attachment of the delivery tip. The dispensing and accurate placement of caustic or reactive dental materials is facilitated, making dentistry easier.
