In general there are three different types of dental x-ray’s
- Intra oral x-rays – these are small x-rays taken within your mouth to detect decays and infections
- OPG x-rays – these are larger x-rays taken around your face to analyse larger facial anatomical structures
- CBCT x-rays – this is a 3-D x-ray taken to analyse the facial anatomy in three-dimensional form
There are three main routine x-rays taken in the dental clinic. In the dental clinic x-rays are referred to as radiographs.
There are bitewings, periapical radiographs and dental panoramic tomography. The most common is bitewings, which are normally taken as part of a comprehensive check up appointment.
Bitewings show us the structure of your teeth in more detail and allow us to see in between your teeth and your bone levels.
Periapical Radiographs create an image of the crown and root of your teeth and give us a view of the anatomy of the root of your teeth, bone levels and can show us if there are any abscesses or abnormalities beneath your teeth.
Dental Panoramic Tomography is more commonly referred to as an OPG. It gives a 2D image of the whole jaw giving a view of all your teeth, your jaw bones, sinus, jaw joints and supporting bone structure. This is one of the best ways of looking at the angle of your wisdom teeth.
Sometimes a referral for other x-rays can be required depending on the treatment you are getting, such as with orthodontics or implants where you may need a lateral view radiograph or a CBCT. Read More
