Abstract: A light curing device has a light source for curing light-polymerizable dental materials. A control circuit controls the light output of the light source according to a pre-determined output profile. The output profile has a starting time period with a decreased output relative to a maximum output, followed by a main curing time period.

Abstract: A syringe-type device for supplying dental material to a dental restoration site includes a syringe body, a syringe connecting body, and an activation component. The syringe body has an outlet and a dental material retaining space for retaining therein a dental material. The syringe connecting body has an upstream opening and a downstream opening and is connectable to the syringe body such that dental material which has exited the syringe body through the outlet thereof flows through the upstream opening into the syringe connecting body and subsequently flows through the downstream opening to the dental restoration site. The activation component is disposable at the outlet of the syringe body and, in a non-actuated condition thereof, at least partially blocks the flow of dental material from the syringe body into the syringe connecting body and, in an actuated condition thereof, permits a relatively greater flow of dental material.

Abstract: A cavity filling apparatus is provided for filling a cavity in a cavity containing member such as a tooth and a restorative dental piece. The cavity filling apparatus includes a filling mass ready space for retaining therein a filling mass, a suction conduit, and an adapter having an adapter channel.
