Description

Dental plaque detection device

Technical Field

The present application relates to the field of dental detection, and more particularly, to a dental plaque detection apparatus.

Background

With the improvement of living standard, people pay more attention to health, particularly oral health, teeth are important components of human bodies, and the health degree of the teeth can greatly influence the life quality of people. Dental plaque is easy to cause dental caries and periodontal diseases, and acidic metabolites of dental plaque can corrode teeth to cause dental caries. Mature plaque is more difficult to remove than primary plaque, calcifies to form calculus, and stimulates engorgement and inflammation of the gums, leading to periodontal disease.

Plaque is a soft, unmineralized bacterial population that is either adhered to each other, or to the surface of the tooth, interdental, or restorative surfaces, surrounded by a matrix, and is a bacterial biofilm that cannot be washed away or rinsed away with water. Preliminary analysis is carried out on domestic patents, and dental plaque detection methods in the prior art are mainly divided into three categories, wherein one category is detection by scraping a sample from the tooth surface of a subject, carrying out bacterial culture in a laboratory, observing under a magnifier and the like; one is a reagent-based plaque detection agent (plaque stain); one type is a dental plaque detection device of equipment, which can be specifically divided into a special dental plaque detector, an intelligent toothbrush with a dental plaque detection function and the like.

1. ) In the prior art, a bacteria culture mode is to scrape a sample from the tooth surface of a subject, perform bacteria culture in a laboratory, observe under a magnifier and the like for detection, and the methods are limited by experimental conditions to a great extent and can only be performed in oral medical institutions, and the subject is difficult to simply and quickly know results.

2. ) Plaque detection is also typically stained with a plaque stain and viewed by a doctor. CN 103908680B describes a dental plaque detection agent, which is safe, nontoxic, long in effective time and capable of effectively reducing the stimulation to sensitive teeth. However, the lips and the oral cavity are easily stained during the use of the dental plaque stain, and repeated cleaning is required.

3. ) In the prior art, most dental plaque detectors irradiate light rays with a specific spectrum onto dental plaque, a light source in the wavelength band emits visible fluorescence, and the fluorescence is generated because carboline photosynthesites exist in bacterial metabolism, particularly protocarboline (PP 9), PP9 and similar carboline molecules are derivatives of hemoglobin and are elements for synthesizing heme; PP9 is found in large numbers in gram-negative dental bacteria, and its levels increase as the plaque biofilm matures. Therefore, the determination can be made based on the imaging effect of dental plaque under a specific spectrum of light. CN 210811694U discloses an oral cavity health bacterial plaque detector, including handheld detection main part, lens hood, light filter, at least two LED purple light lamps, rechargeable battery, lighting control circuit board and switch. The upper part of the hand-held main body is a measuring part (ring shape), and the lower part is a holding handle. A device for detecting plaque on teeth is described in CN 105636479B. Includes a light emitting device, a light receiving device, a light detecting device and a processing device. Plaque is determined based on the ratio of the intensity of the detected light at two different distances. CN 213098486U describes a dental plaque intelligent detection appearance, including the device body, the device body includes the handle and connects the detection piece in the handle upper end, be equipped with the function on the lateral surface of handle, the detection piece includes the camera, stretches pole and connecting seat in, the upper end of camera and interior pole is connected. The oral cavity image information and information such as dental plaque distribution range and local concentration can be acquired through the laser emission module level image acquisition module.

In the prior art, the dental plaque detection function is integrated on the electric toothbrush, that is, besides the function of oral cleaning, the dental plaque is also irradiated with light of a specific spectrum, and the dental plaque is determined according to the imaging effect of the dental plaque under the light of the specific spectrum. CN 209846407U discloses an oral cleaning device and a light emitting module, the oral cleaning device comprises a handle, a cleaning member, a power source, a light emitting module and a starting element. CN 112220573 invented a U type dental plaque detection toothbrush, CN 205492987 provided an intelligent toothbrush with dental plaque detection, CN 208942464U disclosed a domestic dental plaque detection cleaning device.

A part of dental plaque detectors (such as CN 105636479B, CN 213098486U) and intelligent toothbrushes with dental plaque detection functions (such as CN 208942464U, CN 205492987U) all have the common point that one end with a light source with a specific wave band is required to be placed in a mouth, a camera is used for replacing the naked eye to record the intensity of fluorescence, a fluorescence photo of a dental surface is obtained, and the condition of dental plaque is observed. Because of the limitation of shooting in the mouth, the shooting process is increased, and certain operation requirements are provided for operators. In addition, the traditional Chinese medicine preparation is required to be placed in the oral cavity and directly contacts the oral cavity, and once the traditional Chinese medicine preparation is not sufficiently used in a crossed manner in a protection and disinfection manner, various diseases are infected. Some simple dental plaque detecting instruments (such as CN 210811694U) do not need to place a light source in the mouth and take a picture, but have the disadvantages that in actual operation, when the LED lamp with a special waveband illuminates the inside of the mouth, the position of the LED lamp is fixed, the irradiation angle cannot be adjusted, and the distribution of dental plaque in the mouth is inconvenient to irradiate and observe at multiple angles, especially for the maxillofacial observation of the upper dental arch and the labial dental surfaces at two sides.
