Dental
x-rays are being used by dentists to detect diseases and
conditions of the teeth and surrounding tissues that may not be
apparent on a simple oral exam. They are also helpful in treating any
potential problems early on before they develop into something worse.
The frequency of x-rays will depend on the patient’s medical
condition, as well as his or her medical or dental history.
The following are some of the things dental X-rays can reveal:
-
Areas of decay, especially small ones between teeth
-
Bone loss
-
Developmental abnormalities
-
Teeth condition, in preparation for procedures like braces, tooth implants, and dentures
-
The condition, position, and size of incoming teeth in children
There are
two main types of dental X-rays: intraoral and extraoral. In
intraoral X-rays, the film is placed inside the mouth, while in
extraoral procedures, the film is outside the mouth. The more
commonly used type is intraoral, which allows dentists to check the
health of the roots of teeth, as well as the bone surrounding them.
It also helps in studying the development and general health of
teeth, and in finding caries. On the other hand, extraoral X-rays put
more focus on the jaw and skull. It is used to identify impacted
teeth, check for any effects of teeth on the growth and development
of the jaw, and identify any potential temporomandibular joint, or
TMJ, problems.
