ABSTRACT:
A dental cartridge for dispensing a dental material having a body portion made of a material transparent to at least a portion of the visible light spectrum and opaque to the actinic light of the dental material contained therein. Also, a dental cartridge having a body portion formed from a toroidal segment and a coaxial nozzle attached thereto. The dental cartridges are used in a dental syringe for application of the dental material to a patient. Several embodiments provide various discharge end configurations, including hemispherical, conical frustum, and flat. Additionally, dosing indicia are placed on the body portion of the dental cartridge, permitting the dentist to fill the dental cartridge with a predetermined volume of dental material. A specially configured piston having an appendage thereon is used in combination with the dental cartridge for extruding substantially all of the costly dental material therein.
