Digital X-Rays

Dental Cavity

Based on your dental history and condition our Dentists will examine your mouth and decide whether you will need a dental X-Ray examination. X-rays often provide information essential for detection, diagnosis, and treatment of conditions that can threaten your oral and general health. If you are a new patient, the dentist may ask you to have completed X-rays to determine the present health of your mouth. Afterwards, you may need X-rays only when information is needed about a particular problem like impacted teeth. Children may need X-rays taken more often (every 6 months) than adults because their teeth and jaws are still developing

How Dental X-Rays will help?

There are many diseases of the teeth and surrounding tissues that cannot be seen when your dentist examines your mouth. If X-rays are not used, small cavities between teeth, abscesses, cysts, tumors, and other diseases may be impossible to detect until obvious signs and symptoms have developed and serious damage has been done to your health.

Different Type of Dental X-Rays

Dental X-Rays are divided into two main categories: intraoral, which means that the X-ray film is inside the mouth; and extraoral, which means that the film is outside the mouth.

Intraoral Radiographs:

The various types of intraoral X-rays show different aspects of the teeth:
Bite-wing X-rays highlight the crowns of the teeth. On each radiograph, the upper and lower teeth in one portion of the mouth are shown, from the crown to about the level of the jaw.

Periapical X-rays highlight the entire tooth. On each radiograph, the teeth from either the upper or lower jaw in one portion of the mouth are shown. The difference from bitewings is that in a periapical X-ray, the whole tooth is shown, from the crown down past the end of the root to the part of the jaw where the tooth is anchored.

Periodically, a dentist may recommend a “full-mouth radiographic survey,” or FMX. This means that every tooth, from crown to root to supporting structures, will be X-rayed using both bitewing and periapical radiographs.

Occlusal X-rays are larger and highlight tooth development and placement. On each radiograph, nearly the full arch of teeth in either the upper or lower jaw is shown. These X-rays are taken with the X-ray machine either pointing straight down from near the nose (to take pictures of the upper jaw and teeth), or straight up from under the chin (to take pictures of the lower jaw and teeth).

Digital radiographs are one of the newest X-ray techniques around. With digital radiographs, film is replaced with a flat electronic pad or sensor. The X-rays hit the pad the same way they hit the film. But instead of developing the film in a dark room, the image is electronically sent directly to a computer where the image appears on the screen. One of the great advantages of this process is that radiographs can be digitally compared to previous radiographs in a process called subtraction radiography. The computer can digitally compare the two images, subtract out everything that is the same and give a clear image of anything that is different. This means that tiny changes that may not be noticeable with the naked eye can be caught earlier and more clearly with digital-subtraction radiography.

Extraoral radiographs:

Extraoral X-rays are made with the film outside the mouth. Extraoral X-rays are less detailed than intraoral X-rays, so they are not used for detecting caries or flaws in individual teeth. They show teeth, but their main focus is on the jaw or skull. Extraoral radiographs are used for monitoring growth and development, looking at the status of impacted teeth, examining the relationships between teeth and jaws and examining the temporomandibular joint or other bones of the face.

Panoramic radiographs show the entire mouth area – all teeth on both upper and lower jaws – on a single X-ray. This type of X-ray requires a special panoramic X-ray machine. The tube head that emits the X-rays circles behind the patient’s head, while the film simultaneously circles across the front. That way, the full, broad view of the jaws is captured on one film. The machines may have chin rests, forehead rests, and side head positioners, plus bite-blocks that patients will be asked to close their teeth around. But the process is very safe and often uses less radiation than intraoral radiographs.
