bitewing
Học thuậtThân thiện
Definition
Noun: A small, rectangular dental X-ray film or digital sensor. It has a protruding tab or "wing" that the patient bites down on to hold the film securely in position between the upper and lower teeth. This allows for a clear radiographic image of the crowns of the teeth and the adjacent bone, primarily used to detect cavities between teeth (interproximal caries) and to monitor bone levels.
Usage
The term "bitewing" is used specifically in the context of dental examinations and radiography. It refers to the physical film/sensor and, by extension, the type of X-ray image produced.
Examples
- The dentist took two bitewings to check for cavities between my molars.
- A routine dental check-up often includes bitewing X-rays.
- Please bite down firmly on the bitewing to hold it still.
Advanced Usage
- Bitewing radiograph/series: Refers to the set of images taken, typically including views of both sides of the mouth.
- The new bitewing radiographs showed no signs of decay.
Variants and Related Words
- Bitewing radiography: The technique or process of taking bitewing X-rays.
- (Note: "Bitewing" is a compound noun. It is not commonly used as a verb or adjective outside of this specific dental context.)
Synonyms
- Interproximal radiograph (a more technical term describing the image's purpose).
- Dental X-ray film (a broader, less specific term).
Antonyms
- Periapical X-ray (a different type of dental X-ray that shows the entire tooth, including the root and surrounding bone, rather than just the crowns).
- Panoramic X-ray (a broad, single image of all the teeth and jaws).
Related Phrases/Idioms
(This is a highly technical term with no common idiomatic or phrasal verb usage.)
Noun
