Final answer:
Bite wing x-rays are used by dentists to detect decay between teeth, check bone density for gum disease, and monitor the condition of fillings. The patient bites on a film while a low-energy radiation x-ray machine captures the image.
Step-by-step explanation:
Bite wing x-rays are a diagnostic tool used by dentists to detect dental conditions that may not be visible during a regular visual examination. This type of x-ray image is especially effective in revealing decay between teeth and the changes in bone density that could indicate the presence of gum disease. Beyond detecting decay, bite wing x-rays can help to identify fillings and check their conditions over time.
The process involves placing a small x-ray film in the mouth, which is then bitten down on, hence the term 'bite wing.' The dentist positions the x-ray machine adjacent to the patient's cheek to capture the targeted area. The result is a radiograph that shows the upper and lower teeth in a specific area of the mouth in a single view.
It is important to note that while x-rays do involve exposure to radiation, modern dental x-ray machines produce relatively low-energy radiation to minimize patient exposure.
