Background

The oral cavity is used as an important structural tissue of a human body, and the oral cavity problems are more and more along with the improvement of the abundance of living contents of people, wherein the number of patients suffering from oral cancer is increased day by day. The examination of the oral lesion tissues as the auxiliary diagnosis of the oral cancer detection has important significance for the early oral cancer screening. One means of examination of diseased tissue in the mouth involves autofluorescence techniques. The autofluorescence technique is a non-invasive screening technique based on the optical characteristics of tissues, and does not damage the physiological functions of normal cells. The healthy oral mucosa contains abundant endogenous autofluorescent groups. These fluorophores, when excited by a light source of appropriate wavelength, are capable of generating an autofluorescence signal corresponding to their absorption spectra. This fluorescence phenomenon is not dependent on any exogenous material and is inherently present in vivo, and is called autofluorescence. An autofluorescence device (VELscope Vx) is a handheld device used for clinical screening of OPMD based on the principles of fluorescence imaging. When blue excitation light emitted by the VELscope Vx contacts with the endogenous autofluorescent groups, the fluorescent groups of the mucous membrane of the healthy oral cavity emit light green fluorescence with the wavelength of 515nm, while in epithelial dysplasia and OSCC pathological tissues, the distribution of the fluorescent groups is damaged, and the local color is dark after the excitation light irradiates to form a fluorescence deficiency phenomenon. Chinese patent CN100479736 provides an intra-oral cavity camera device having an illumination device.
