Dental X-rays
There are three most commonly used types of dental X-rays.
Bitewing X-rays- most commonly used during a routine oral check-up. This is useful for revealing cavities that can be hiding between teeth.
Periapical X-rays- show the entire tooth and include the roots as well as the surrounding bones.
Panoramic X-rays-give a broad overview of the entire mouth. The panoramic X-ray helps supply information about the teeth as well as the upper and lower jawbone, sinuses, hard and soft tissues of the head and neck.
The benefit of a Panoramic X-ray is, unlike other X-rays where the film is placed inside the patient’s mouth, the panoramic film is contained in a machine that moves around the patients head. Some may be familiar with Panoramic X-rays because it is the type of dental x-ray usually used when the wisdom teeth are being evaluated.
Panoramic X-rays will reveal deep cavities and gum disease. The panoramic X-ray has many other uses such as evaluating patients with TMJ or jaw problems. Also, it can help dentists evaluate the mouth structure of those who require full or partial removable dentures, dental implants, or braces. People who are at risk or suspected of having oral cancer or other tumors of the jaw, have impacted teeth (especially wisdom teeth) or have had any recent trauma to the face or teeth can have their dentist or oral surgeon use a panoramic X-ray to help determine a diagnosis.
Panoramic X-ray is very important if you want a thorough dental examination. Panoramic X-rays are recommended every 5-7 years, as it can help determine any other problems that a normal X-ray can not.
