Abstract
A device for dispensing a dental material has a cartridge with a dispensing end. The dispensing end has a dispensing opening for the dental material. The dispensing end further has in essence an axially symmetric shape with a truncation. The truncation provides the dispensing end with a generally flat dispensing surface through which the dispensing opening extends. The device has further a cap received on the dispensing end. The cap and the dispensing end are rotatable relative to each other between an open position, in which an orifice in the cap uncovers the dispensing surface, and a closed position, in which a closed space is formed between the cap and the dispensing surface. The device allows for a relatively convenient dispensation of dental material, in particular for a dispensation of a dental composite filling material.
