3. PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the invention and the manner in which it is to be performed: 4. DESCRIPTION:
Field of the invention:
[0001] The present disclosure generally relates to the technical field of intraoral medical devices, and in specific relates to a portable intraoral screening device for multiple oral abnormalities that aids for automatic emission of specific wavelength of light based on selected disease.
Background of the invention:
[0002] Dental health is the most commonly neglected aspect in human health. Various lifestyle-related diseases and infections can be traced back to the causes of mastication and occlusal functions related to nutrition intake, as well as the effects of oral bacteria. Survey results show that people who regularly visit dentists tend to have lower annual total medical costs for all illnesses, and regular oral screening aids in early detection of oral cancer. In addition to being connected, it has been recognized that it is also effective in curbing medical expenses for the public.
[000S] The Global Burden of Disease Study 2017 estimated that oral diseases affect close to S.5 billion people worldwide. Some of the most common oral health conditions include dental caries (tooth decay), periodontal diseases, oral cancers, oral manifestations of HIV, oro-dental trauma, cleft lip and palate, and noma (severe gangrenous disease starting in the mouth mostly affecting children). However, most oral health conditions are largely preventable and can be treated in their early stages by regular screening.
[0004] Spectroscopic devices and endoscopes are being widely used as imaging devices based on tissue optics for screening and diagnostic purposes. Tissue optics refers to the effect of light on living tissue. In the identification of oral cancers blue light (wavelength 400- 490nm) has been used to identify abnormal tissues via fluorescence visualization loss (FVL).This technique is particularly useful as blue light penetrates about 1mm deep, and over 95% of all oral cancers are squamous cell carcinomas. Tumours tend to exhibit lower levels of autofluorescence when compared to healthy tissue due to their increased metabolic activity. This increase in metabolic activity leads to the breakdown of the extracellular matrix as well as decreased concentration of Flavin adenine dinucleotide (FAD).
[0005] In existing technology, device and disposables for determining a patient risk for oral cancer in the same visit when a sample is collected is known. The VELscope is a device that aids to reveal oral cancer that that are indiscernible with the naked eye during standard examinations and cannot be used in a low resource setting due to economic constraints based on the cost of the device, and the sensitivity of many such devices still remain low. These devices lack image sensors and therefore neither visualizes the margins of the lesions nor any PMDs.
[0006] In updated technology, an oral cancer screening device is used for the detection of pre-cancerous and cancerous tissue. The device includes a power supply, an illumination source, a selector switch that enables the activation of a specific wavelength of light from the illumination source, an electrical system in communication with the selector switch and the illumination source, a heat sink in thermal communication with the illumination source, a filter or cover to protect the illumination source, and a transparent sheath for providing a sanitary shield for the device when it is brought into contact or close proximity with the patient oral cavity. The selector switch enables the user to switch different colours of light to examine the cancer. The operator will optionally utilize head mounted lenses to assist the operator's visualization of the light from the illuminated oral cavity. However, there is a need for an intraoral screening device that aids to detect different diseases with automatic emission of corresponding wavelength of light.
[0007] Therefore there exists a need for an intraoral screening device that aids to detect different diseases with automatic emission of corresponding wavelength of light. There is a need for an intraoral screening device that aids the operator to choose a specific disease to be screened and emits corresponding wavelength of light for a specific disease. There is a need for a screening device that detect different oral diseases such as oral caries, cavities, gingivitis, periodontitis, fluorosis, and oral cancer in primary stages to avoid severity of diseases that usually have no symptoms. There is a need for a screening device that aids the operator to capture oral image without disturbing the position of the probe. There is a need for a screening device that displays affected regions in different colours. There is a need for a device that provides access to captured images to the health care professional for remote diagnosis.
Objectives of the invention:
[0008] The primary objective of the invention is to provide an intraoral screening device for oral abnormalities that aids for automatic emission of specific wavelength of light based on selected disease.
[0009] The other objective of the invention is to provide a screening device with a shutter button that aids the operator to capture oral image without disturbing the position of the probe.
[0010] Further objective of the invention is to detect different oral diseases such as oral caries, cavities, gingivitis, periodontitis, fluorosis, and oral cancer in primary stages to avoid severity of diseases that usually have no symptoms.
[0011] Yet another objective of the invention is to provide a screening probe that is connected with fluorescence imaging technology either through wire or wireless to distinguish the affected regions from the healthy region.
[0012] Further objective of the invention is to provide an interactive touch display that enables the operator to choose a template of the screening disease.
[0013] Another objective of the invention is to provide an additional camera that aids to detect other oral diseases such as hairy tongue and malocclusion and to capture personal details of the patient.
[0014] The other objective of the invention is to provide a single screening device to screen multiple oral diseases that displays affected regions in different colours.
[0015] Yet another objective of the invention is to provide access to the raw image and processed image to the health care professional for remote diagnosis. [0016] Another objective of the invention is to process the captured images in a remote server using artificial intelligence and machine learning algorithms.
[0017] Further objective of the invention is to provide a disposable plastic cover on the probe for each patient.
