Portable dental examination device and control method thereof

Abstract

The invention provides a portable tooth examination device and a control method thereof, and relates to a device for examining dental plaque by utilizing fluorescence and a control method thereof. The portable tooth examination device comprises a fluoroscope which has deep-blue LED and colorful image collection functions and can extend into the dental cavity of a user, and a universal smart mobile phone with a touch display screen and WiFi communication function, wherein the fluoroscope does not use a mobile deep-blue filter or a drive unit thereof, but has a WiFi communication function, and can be used for transferring a collected image outward; after a specific control program is introduced into the mobile phone, the mobile phone is used for receiving dental image data which consists of red, green and blue channel images and is transmitted by the fluoroscope and deducing data of the blue channel image in the dental image data; a dental image of the red fluorescent image which is generated from dental plaque under deep-blue excitation is remarkably displayed on the touch display screen; and a user can spontaneously examine whether teeth have dental plaque or not. The device has high reliability, long service life and good economical performance.

Description

technical field [0001] The invention relates to a device for inspecting dental plaque by using fluorescence and a control method thereof, in particular to a device and a control method for inspecting teeth by using light-emitting diode lighting to make dental plaque produce fluorescence. Background technique [0002] The process of normal dental lesions turning into dental caries is: bacteria generated by food residues gather on the tooth surface to form plaque, and the plaque continues to develop to form soft plaque, which combines with minerals in the saliva in the mouth to calcify to form hard plaque Tartar (also known as dental calculus); the surface of tartar is more likely to accumulate bacteria, and the acidic substances secreted by these bacteria corrode the enamel on the surface of the tooth, and then corrode the dentin (also known as dentin) of the tooth, forming perforation (caries). Plaque and soft dirt can be removed by brushing with toothpaste, while tartar nee...

Problems solved by technology

[0010] The portable dental inspection device of the present invention breaks through the customary thinking that the dark blue filter must be used to filter out the dark blue light in the fluorescent tester to observe the red and green fluorescent images. Instead of using the movable dark blue filter and its driving unit, it uses The mobile phone software subtracts the data of the blue channel image from the tooth image data composed of red, green and blue channel images sent by the fluoroscope to realize the function of filtering out or partially filtering out deep blue light, which fundamentally solves the problem of reliable Insufficient performance and long service life: At the same time, it avoids the problems of unclear imaging caused by light leakage and light refraction during the use of the movable dark blue filter
