Dental caries diagnostic imaging device and handheld dental caries diagnostic imager

Abstract

The invention discloses a dental caries diagnostic imaging device and a handheld dental caries diagnostic imager. The device comprises an embedded control module, a laser device driving module, a near-infrared semiconductor laser device, an output optical fiber, a return optical fiber and a shooting device, wherein the embedded control module is provided with an on-chip micro-control unit and an upper computer image processing unit; the on-chip micro-control unit receives a control command and controls the laser device driving module; the laser device driving module adjusts the light power ofnear-infrared light output by the near-infrared semiconductor laser device, and the output optical fiber irradiates the near-infrared light onto a detected tooth; the shooting device collects transmission images of the detected tooth through the return optical fiber, and the transmission image is sent to the upper computer image processing unit; the upper computer image processing unit processes the transmission image, and the lesion area is highlighted when it is detected that the detected tooth has the lesion area. According to the technical scheme, ionizing radiation in the dental caries diagnosis process can be reduced, and reliability and accuracy of dental caries diagnosis can be improved.

Description

technical field [0001] The invention relates to the technical field of oral disease diagnosis, and more specifically relates to a dental caries diagnostic imaging device and a hand-held dental caries diagnostic imaging instrument. Background technique [0002] At present, although the prevention, diagnosis and treatment of dental caries have been greatly improved, according to the statistics of the World Health Organization, dental caries is still the highest incidence of all oral diseases, and it is an oral disease that affects all age groups. According to clinical data, if dental caries is not treated in time and correctly, it will lead to permanent tooth damage and even cause tooth loss. Therefore, it is necessary to diagnose dental caries so that dental caries can be treated in time. [0003] The existing dental caries diagnosis method basically uses X-rays to irradiate the teeth to make the teeth produce fluorescence with different intensities, and uses the strong corre...

Problems solved by technology

However, because X-rays will produce ionizing radiation, and this type of radiation will cause relatively great harm to the human body, this method is not suitable for special groups such as pregnant women and children, and because the excessive overlap of tooth enamel makes X-rays The reliability of detection is relatively low, which will reduce the accuracy of diagnostic results
