摘要： 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.

摘要： The shade matching method and device of the subject invention is to be used by dentists and dental professionals to help in determining the correct shade of porcelain crowns, composite fillings and other cosmetically critical dental restorations. Based on the principle of metamerism, the method consists of using a light source for generating a light spectrum in at least two distinct wavelength spectra in sequence under the control of the operator of the light source inclusive of a first wavelength spectrum corresponding to daylight to enable the dentist or dental professional to perform a shade match the way a patient would view their restoration outside of a dental office in a real world environment and then switching to a second wavelength spectrum corresponding to either room light or ambient light.
