Abstract: A dental light polymerization device (1) having a housing (2), a light source for emitting blue light, a piezoelectric transmitter (7) and at least a piezoelectric first receiver (8). The transmitter is acoustically coupled with the housing for transmitting an acoustic wave into the housing and the first receiver is acoustically coupled to the housing for picking up the acoustic wave from the housing. The transmitter and the first receiver are arranged spaced from each other with a portion of the housing between the transmitter and the first receiver forming a first touch surface.

Abstract: A dental light polymerization device has an intra-oral tip portion and a handle portion. A polymerization light source and a camera are accommodated in the dental light polymerization device. The camera has an image input arranged within the tip portion and the polymerization light source is formed by a plurality of polymerization light outputs that are arranged around the image input. The dental light polymerization device further has a light refraction panel in which a plurality of lenses are interspersed. The light refraction panel is arranged with the lenses being each positioned in front of a corresponding polymerization light output of the plurality of polymerization light outputs.

Abstract: Cure monitoring systems for and methods of monitoring polymerizable material to determine the degree of curing of the polymerizable material. A monitoring light source delivers visible monitoring light at one or more different visible wavelengths and a visible light detector detects the monitoring light diffusely reflected by the polymerizable material. The monitoring light has a wavelength of maximum emission (λmax-mon) that does not effectively induce polymerization of the polymerizable material. Change in intensity of the monitoring light reflected from the polymerizable material is used to determine when a selected degree of curing is reached in the polymerizable material.

Abstract: A dental light irradiation device (1) which has a light emitting diode/LED (15) and a heat sink (16) for dissipating heat generated by the LED. The heat sink (16) is formed of a composition which includes a polymer and a filler. The filler provides the composition with increased thermal conductivity relative to the polymer alone. The invention helps maximizing the convenience in handling of dental light devices.

Abstract: A dental light irradiation device is adapted to emit blue light. The device has a light source, means for collimating light emitted from the light source, and a light guide. The light collimating means comprising:—a plano-convex lens oriented with the planar side toward the light source, and—a reflector formed by a hollow ring-shaped structure having an inner conical and reflective surface. The reflector is arranged such that its inner cross-section widens toward the lens and extends over the entire distance between the planar side of the lens and the light source. The light source being positioned substantially at the effective focal length of the lens, and the light guide having an input side for receiving light emitted from the light source and an output side for the light.

Abstract: A heating device for heating a dental material. The heating device has a body and a socket. The socket is removably received within the body and has a socket wall that forms a receptacle for positioning a container for the dental material therein. The body has a light source for emitting light toward the socket wall in a direction toward the receptacle. The socket wall is at least partially transmissive for infrared light. The heating device allows for heating the dental material within the container.

Abstract: A dental light irradiation device has a first light source for emitting blue light, a camera and at least a first detector. The device is operable in a camera mode in which the camera is activated and in a non-camera mode in which the camera is deactivated. In the non-camera mode a user input on the first detector activates the camera mode. The dental light irradiation device helps facilitating the proper curing of a dental material in a patient's mouth.
