Bitewing
Bitewing
Bitewing (pronunciation: /ˈbʌɪtˌwɪŋ/) is a type of dental radiograph that is commonly used in dentistry. The name "bitewing" comes from the small tab of plastic, which the patient bites on to hold the X-ray film in place.
Etymology
The term "bitewing" is derived from the action that the patient performs during the procedure. The patient "bites" on a "wing" or tab attached to the X-ray film or digital sensor, hence the term "bitewing".
Usage
Bitewing radiographs are used to visualize the crowns of the upper and lower teeth simultaneously and the area of the teeth just below the gum line. They are particularly useful for detecting caries (tooth decay) and changes in bone density caused by gum disease.
Procedure
During a bitewing radiograph, the patient bites down on a plastic holder that contains the X-ray film or digital sensor. The X-ray machine is then positioned to direct a beam of X-rays through the teeth and onto the film or sensor. This produces an image of the teeth and surrounding structures.
