Dentists want to provide the best possible dental care to their patients, but a visual examination doesn’t tell them everything they need to know. Thanks to Dental X rays, dentists can accurately diagnose and treat dental problems early before they become serious. X-rays are also called radiographs. They are used to check for cavities and evaluate the extent of decay. They are also used to check the presence of any cyst, or abscesses. Congenital missing or impacted teeth such as wisdom tooth are often identified by this way, and the presence and extent of bone loss due to periodontal disease is easily seen through in dental Xrays.
Types of X-rays
1)Bitewing radiograph . .
1)Bitewing radiograph : During routine examination, your dentist may take two to four Bitewing Xrays which show the crown portion of your teeth, to check for early signs of decay between your teeth.
2) Periapical radiograph : when he wants to get a good look at your bone height, or any abscess which is found in root tip, Peri apical xray provides the best view.
3)Panoramic radiograh :It is taken from outside your mouth and produces an image of entire oral cavity on one large xray. The image shows all of the teeth as well as upper and lower Jaws and sinus areas. This type of xray can identify impaction cysts, tumors, jaw disorders and bone irregularities Other radiographs include Xrays which are occasionally taken in children to evaluate their developing teeth.
Dental X-rays safety :
Xray machines and other sources of dental Xrays are designed to minimise radiation, these processes are safe and your exposure is negligible. Many offices in fact are now using digital Xrays which further reduces radiation exposure.
