Abstract: An optical curing apparatus includes a front shell body which consists of a first shell and a second shell that are coupled in a detachable and turnable manner. A light channeling member is fastened to the first shell and may be adjusted angularly to suit user's requirements. The light channeling member and the first shell are detachable. They are adaptable to the light channeling member of various diameters, and may be removed for sterilizing, or become a disposable and replaceable item. A radiation member and an electric power supply unit are provided and detachably coupled through a connector. The radiation member is reusable even if the case is damage or other elements are breakdown.

Abstract: An optical curing apparatus consists of a body, a gun and control circuits located in the body and the gun to solidify dental resin filling in the decayed teeth in the shortest time so that the dental resin will be filled in the teeth firmly and repeated teeth decay may be avoided. The control circuits may control light projecting time period and adjust optical output power, and detect if optical power output is normal. When the optical output power is below a preset standard value, the apparatus will generate an alert to notify users to replace the lamp set in the curing apparatus.
