Dental mirror is a medical device used for oral examination and treatment, and its principle is mainly based on optical reflection. Specifically, when the oral lens is inserted into the patient's oral cavity, the light is reflected from the lens above the oral lens into the oral cavity, then reflected back above the lens through the tissues, and is observed by the eyes again. In this way, doctors can clearly observe the situation inside the oral cavity. Orthodontic mirrorsis applicable to multiple medical departments, including:
1. Dentistry: Oral mirror are the most widely used in the field of dentistry, mainly for the examination and treatment of problems with teeth, gums, oral mucosa, etc.
2. Oral and maxillofacial surgery: Oral endoscopy can assist doctors in observing and diagnosing diseases in the oral and maxillofacial region, such as oral tumors and temporomandibular joint diseases.
3. Otorhinolaryngology: Otorhinolaryngology can assist doctors in observing and diagnosing problems in the larynx, nasal cavity, pharynx, etc., such as vocal cord polyps and tonsillitis.
4. Ophthalmology: Oral lenses can be used for eye examinations, such as checking the conjunctiva, cornea, etc.
Characteristics of the oral lens:
Convenient and fast: The Laryngeal mirrorcan be easily placed in the patient's mouth, and the internal conditions of the mouth can be reflected through the lens, which is convenient for doctors to conduct examinations and treatments.
2. Safety and hygiene: The oral lenses can be used only once or reused after strict disinfection, which can prevent cross-infection and the spread of diseases.
3. Clear field of vision: By reflecting the internal conditions of the oral cavity through transparent lenses, a clear field of vision can be provided, helping doctors make more accurate diagnoses and treatments.
4. Wide range of applications: Oral endoscopes are not only suitable for examination and treatment in the dental field, but can also be applied in medical fields such as otorhinolaryngology and ophthalmology.
The structure and composition of the endoscope: Handle. The handle of the Plastic dental mirror has a certain thickness and length, which is convenient for doctors to hold and use. Lenses come in various shapes, sizes and angles. You can choose the appropriate model and accessories according to your needs. Bracket, the bracket is used to support the lens, maintaining its stability and position unchanged. Other accessories: Some oral endoscopes are also equipped with suction devices, light sources and other auxiliary equipment to enhance the examination and treatment effects. There are various material options for oral lenses. Common materials for oral lenses include:
1. Glass: Glass mouth lenses have high transparency and clear imaging, which can provide a better observation effect. However, glass glasses are relatively brittle and prone to breakage, so they need to be handled with care when in use.
2. Plastic: Plastic eyeglasses are lightweight, sturdy, not prone to breakage, and more convenient to use. However, its transparency and imaging effect may not be as good as those of a glass lens.
3. Metal: Metal glasses are usually made of stainless steel and have strong durability and corrosion resistance. However, since metals reflect light, it may affect the imaging effect.
