Patent ID: 7955076

Claim:
A dental caries detecting device, comprising: an ultraviolet light source that irradiates ultraviolet light of at least two different intensities, including ultraviolet light of first intensity and ultraviolet light of second intensity, onto a single measuring area of a tooth; a fluorescence receiving portion that receives fluorescence from the single measuring area of the tooth in response to the ultraviolet irradiation of the at least two different light intensities from the ultraviolet light source; a fluorescence data analysis portion that analyzes fluorescence data transmitted from the fluorescence receiving portion; and a data display portion that displays data analyzed by the fluorescence data analysis portion, wherein the fluorescence receiving portion receives first fluorescence by the ultraviolet light of first intensity and transmits first fluorescence data to the fluorescence data analysis portion, the fluorescence receiving portion receives second fluorescence by the ultraviolet light of second intensity and transmits second fluorescence data to the fluorescence data analysis portion, and said fluorescence data analysis portion analyzes the first fluorescence data and the second fluorescence data in at least one wavelength band for detection of a dental caries.
