Abstract

A dental material dispensing device has a plunger means which for dispensing the dental material is movable for urging at least one component of a dental material toward a dispensing area. The device further has cure control means with an energy source and a flow path on which the dental composition and/or the dental material flows past the energy source during dispensation. The device is operable for exposing the dental composition and/or the dental material to a specific energy by control of the energy source and/or by control of the speed of the flow of the dental composition and/or the dental material on the flow path. The device is configured for dispensing a coherent strand of dental material in a dispensing cycle. The device is further configured for operating in a first dispensing mode and additionally in a second dispensing mode during the same dispensing cycle. The ratio between the specific energy in the second dispensing mode and the specific energy in the first dispensing mode is smaller than 1.
