Study Measure Method of Dental Pulp Vitality Using Laser Induced Fluorescence Technology
The state of dental pulp vitality is the key to human teeth healthy whether or not, to effectively detect tooth, the technology of laser induced fluorescence was used to detect dental pulp vitality. The principle that tooth can be excitated fluorescence in the short wavelength irradiation source was analyzed, and the relation between the intensity of tooth fluorescence and the dental pulp vitality were studied, the detection system of dental pulp vitality was designed. Base on detection circuit and gather system, the overall design of fluorescence signal detection system and signal amplification processing were studied and analyzed; ADS7804 and AT89C51 were used to design and gather fluorescence signal coming from tooth, and detection circuit performance was discussed. Through experimentation, different incident laser power or different laser wavelength bring different the fluorescence intensity.
