Description
Technical field
The invention belongs to medical Instrument field, particularly a kind of fluorescence tooth detector.
Background technology
Traditional ultraviolet (UV) spectrum can be divided into three kinds of UV wave band: UVA (315-400nm), UVB (280-315nm claims middle-ultraviolet lamp-leading Exposure to Sunlight reaction again), and UVC (200-280nm also claims short wave ultraviolet).In these three kinds of ultraviolet bands, UVA is minimum to the harm of pathogen, can not produce harm to the human skin tissue that the short time is exposed under the ultraviolet light.In dental diagnosis was used, UVA was a kind of important light wave, and it can make biomaterial produce fluorescence.According to Stokes' law, when the molecule radiofluorescence, the wavelength of emission light color is than the length of exciting light.Such as, behind the molecule absorption ultraviolet light, the release of light is normally accomplished in visible spectrum.When exciting light touches dental surface dental plaque or dental calculus position, UVA light will radiate visible red fluorescence.The appearance of fluorescence is owing to have the carboline photosynthate, especially former carboline (PP9) in the antibacterial.The derivatives that PP9 and similar carboline molecule are hematochrome is the synthetic key element of heme.PP9 comes to light and is present in a large number in the Gram-negative tooth bacterium, and its level can improve along with the biomembranous maturation of dental plaque, and ripe dental plaque and dental calculus that red fluorescence normally is accompanied by on the tooth produce.Laboratory research proof actinomyces dentocariosus (being found in the carious dentin), bacteroides intermedius, corynebacterium and Candida albicans can both radiate the fluorescence of 620-635nm and 700nm under the exciting of 407nm ultraviolet.Based on above principle, the UVA ultraviolet source is widely used in the oral medical instrument.Up to the present, the UVA light source mainly comprises Nitrogen Lasers in traditional oral medical instrument, helium cadmium laser, the high pressure cadmium lamp, high pressure xenon gas lamp and metal halide arc lamps, but these light source volumes are big, cost an arm and a leg and service life short.The advanced theory of application of LEDs technology, the UVA light emitting diode is developed, and the UVA optical wavelength of commercial LED is generally: 375,385,395 and 405nm.This patent adopt peak wavelength be the light emitting diode of 375nm as light source, compare with traditional light source, it is little that the UVA light emitting diode has a volume, long service life, steady performance.Through using the UVA LED source can reduce the cost and the volume of product greatly.Compare with other oral medical instrument, this patent has that cost is low, and volume is little, advantage such as is convenient for carrying.Because the fluorescence that the UVA light emitting diode inspires is fainter, if observe fluorescence, just need to use optical filter, it can see through wavelength of fluorescence rather than excitation wavelength.These optical filters can be that stained glass or polymer also can be comparatively expensive interferometric filters, and it is to be processed at the surface layer of glass ply of different refractivity by insulant.The different wave length of light can cause mutually long and destructive interference, and the part light wave is gone out by transmission and other can be gone back by refraction.So can on the instrument of measuring fluorescence, interference light filter be installed usually.In brief, when dental plaque or dental calculus occur, can improve, in the visual red light district of 590-650nm, fluorescence signal can occur simultaneously in the absorbing power of 350-420nmUVA spectral regions.Through using polarizer (in order to reduce reflection and dispersion) and the orange red light filter of long wave, naked eyes just can be seen the emission of these fluorescence, also can they be recorded in the image system with CCD and cmos sensor.
