    Abstract: An erythema meter includes a probe, a light source of one or more specific probing and reference wavelengths, and an acoustic detector which determines the level of erythema present in the dental pulp chamber of a tooth. The probing and reference wavelengths are delivered in pulsed or amplitude modulated fashion through the probe, thereby permitting electronic identification and filtering of the received data. The absorption of the light wave raises the temperature of the material in the tooth and causes it to expand, thus creating tiny shockwaves which are picked up with the acoustic detector, revealing information on the location of blood and the quantity of blood inside the tooth. The erythema meter accurately measures the erythema, or inflammation, within the tooth in a qualitative and quantitative manner.

    Abstract: The fiberoptic interferometer includes a broadband light source which is selected to illuminate tissue of predetermined organ with light having a wavelength within a predetermined range of wavelengths. Within the predetermined range of wavelengths, the attenuation characteristics of tissue of the predetermined organ define a region of minimum attenuation upon illumination with light having a first wavelength. As a result, the fiberoptic interferometer can precisely determine the optical properties of the tissue and can therefore identify the tissue by comparing the interferometric signal produced upon illumination of the tissue sample with predetermined interferometric signals corresponding to illumination of different types of tissue of the predetermined organ with light having the first wavelength. The fiberoptic interferometer can also include a light source which includes wavelength selection means for controllably selecting the predetermined wavelength of light emitted by the light source. Thus, the optical properties of the tissue can be analyzed at the different wavelengths emitted by the light source to individually determine the optimum wavelength of light for subsequent treatment of the tissue.
