Dental light guide

The present invention is a device that attaches to a light source to transmit and distribute light energy to the surface or internal chamber of a tooth for the purpose of photo-initiation of light curing resins and dental tooth whitening. More particularly, the invention may be used with a single or multiple Light Emitting Diode(s) to more efficiently collect and transmit the light energy emitted by the LED(s) resulting in increased total energy, uniform illumination, and collimation of the light energy delivered to the tooth.

Dental illumination device and method

A dental illumination device is provided that comprises a plurality of light-emitting diodes capable of emitting light of selected wavelengths that do not activate initiator molecules contained within dental restorative material such as dental composite, or at an intensity which is insufficient to initiate substantial polymerization of the dental restorative material. Typically, the dental illumination device produces light having wavelengths not in a range selected from 400 nm to 500 nm, 350 nm to 470 nm and below 350 nm to 420 nm. The dental illumination device may further comprise a switch that allows the aforementioned wavelengths to be switched off or reduced in intensity as required. The dental illumination device may operate as a stand-alone unit or may be fitted to an existing dental light.

Dental light devices having an improved heat sink

The present invention relates to a heat sink material that can more efficiently remove or divert heat from a light source or sources with a given weight of heat sink material when compare to a heat sink made of a solid block of thermally conductive material such as metal. It further relates to a heat sink that can more efficiently remove or divert heat from a curing light device when a reduced weight of heat sink material is used. The inventive heat sink has at least one suitable phase change material including organic materials, inorganic materials and combinations thereof. These materials can undergo substantially reversible phase changes, and can typically go through a large, if not an infinite number of cycles without losing their effectiveness.

Disposable protective sleeve for temporarily covering hand-held dental light curing guns

A disposable protective sleeve for temporarily covering a hand-held dental light curing gun having an elongated handle portion and a barrel portion that tapers to a transmitting end having a light guide from which light emanates, the gun having a curved transitional portion between the handle portion and the barrel portion. The disposable protective sleeve is made from a flexible plastic elongated tubular body with an opening at one or both ends. The body defines a generally straight proximal section and a curved section. The larger end opening is larger than the transmitting end, the barrel portion, the transitional portion and the handle portion of the curing gun, so that the sleeve is adapted to be placed over at least most of the curing gun by passing the larger end opening over the transmitting end, barrel portion, transitional portion and handle portion of the curing gun, so that the sleeve covers at least the transitional portion and at least most of the handle portion of the gun.

Self-positioning dental light filtering device

A self-positioning dental light filtering device is disclosed. The filtering device includes a transparent filter member for blocking optically harmful light emitted from a tip of a dental curing device, and a rotational bearing having an inner component defining an opening for receiving the tip. A retaining device holds the tip substantially centered inside the rotational bearing and substantially rotationally stationary relative to the inner component of the rotational bearing. A counterweight below the rotational bearing causes the filter member to remain in an upright position above the tip when the tip of the curing device and / or curing device itself is rotated.

Dental light curing member and method

The elastomeric member of the present invention is a flexible light guide and curing aid, which permits pressure to be applied to a photo curable material during the clinical restoration of a tooth while simultaneously curing the material by exposing the photo curable material to light. The method of the present invention permits the high forces developed between the occlusal surfaces of opposing teeth when engaged to be utilized to create the applied pressure on the photo curable material. The elastomeric member is soft and has an optically transparent body with a first section having first and second opposing planar surfaces adapted for placement in lateral juxtaposition between the occlusal surfaces of opposing teeth of human dentition and a second section extending from the first section adapted to facilitate contact with a dental light guide while the opposing teeth are engaged.

Optical composite cure radiometer and method

A radiometer and method for providing an indication of the amount of time (exposure duration) needed to cause a light curable dental resin composite material to maximally polymerize in response to the application of light from any light-curing source during the preparation of a dental restoration. It describes a radiometer comprising a sample holder of a size designed to hold a sample equivalent of said dental light curable dental material such that the thickness of the sample of light curable material in the sample holder will correspond to the depth of the composite material in the dental restoration; a solid state light sensor; a microprocessor programmed to respond to the output voltage or change in electrical resistance of the light sensor based upon an algorithm defining a mathematical model representative of the change in light transmission through the light curable dental material as a function of the degree to which said light curable dental material is being polymerized. It includes a time display that is responsive to the output signal generated from the microprocessor for displaying the amount of time (exposure duration) needed to maximally polymerize the light curable dental material in the dental restoration.

Portable color corrected over head dental light to match shades of teeth with true chromatic efficiency and to accelerate tooth whitening

A portable color corrected light for the correct matching of tooth shades and acceleration of tooth whitening has been developed. In order to accurately match the tint and hue (true color) of teeth, the device provides 5500 to 6500 Kelvin, ambient-independent light with the ability to block or overwhelm ambient light to get a precise “color” reading of that tooth. The same light can accelerate the tooth whitening process with the addition of photo-accelerators to increase the decomposition of H2O2 or other peroxide whitening material. In addition, the same light can also serve as a dental operatory light which provides a closer to daylight illumination than conventional halogen dental lights.

A dental system includes a light source, a power supply that adjusts a quantity of light produced by the light source, a measuring device that measures a quantity of light received from the light source, an input, through which user data, including a desired quantity of light, can be entered, and a controller which, together with the measuring device, forms at least part of a feedback loop. The controller receives the user data and communicates with the measuring device and the power supply so that the power supply adjusts a quantity of light emitted by the light source. As a result, the quantity of light received from the light source becomes substantially equal to the desired quantity of light.
