Abstract: A viscous material dispenser, and dispenser system and kit, can include a dispenser without a dispensing tip and one or a plurality of separate dispensing tips that are removably attachable to the dispenser. The dispenser can be used with many different types of viscous material containing capsules and cartridges, such as those containing composites, dental cements, glass ionomers and the like. In embodiments, the dispenser can incorporate an integral activator for multi-component composition cartridges, such as glass ionomer cartridges.

Abstract: A viscous material dispenser for applying a viscous dental material from a capule, cartridge or capsule. The dispenser includes a locking mechanism mounted on the syringe type dispenser to securely retain the capule, cartridge or capsule within the syringe type dispenser while the viscous material is being applied from the syringe type dispenser. The locking mechanism can be positioned so that it rotates around and over the outer circumference of the dispensing barrel of the syringe type dispenser. The locking mechanism can be rotated to an open position where a capule, capsule or cartridge can be inserted or removed from the syringe type dispenser. After a capule, cartridge or capsule is inserted within the syringe barrel, the locking mechanism can be rotated to a closed position where the capule, cartridge or capsule is locked and retained in place for dispensing.
