Dental Radiographs

Dental Radiographs are our best diagnostic tools in dentistry. With the naked eye, we can only see about 60% of what is going on in the tooth. Using Dental Radiographs, however, we’re able to see the areas not visible to the naked eye.

What are Dental Radiographs?

A Dental Radiograph is a digital imaging of the tooth, surrounding structures and bone. This is done by shooting a beam of very low-dosage X-Rays through the tooth onto a phosphor-plate which captures the image and allows us to review it on a computer screen.

Why do we take them?

We take Dental Radiographs to enable us to see as much of the healthy or unhealthy tooth and bone structures as possible. This allows to identify, diagnose and treat problems with much greater accuracy and effectiveness.

Types of Radiographs

Broadly, there are two types of radiographs:

  • Intra-Oral
  • Extra-Oral

Intra-Oral Radiographs

There are three types of Intra-Oral Radiographs:

  1. Peri-apicals Radiographs – These are used to accurately see the tip of the root of the tooth and are often taken when teeth have had Root Canal treatment, have very deep fillings or crowns, or are symptomatic. In these instances, we need to know if there is a chronic abscess present, especially as they are generally tooth specific.
  2. Bite-Wings Radiographs – These Radiographs are used for routine examinations to help assess what is going on around the top and bottom jaw of the mouth. They are very accurate in exposing how deep any decay is and how close it could possibly be to the nerve or bone. They are especially accurate in showing what is going on between teeth, for example if there is any decay developing between the teeth themselves.
  3. Occlusal Radiographs – These are generally used to get a good view of the upper teeth arch, especially if the teeth have suffered traumatic displacement or intrusion.

Extra-Oral Radiographs

There are three types of Extra-Oral Radiographs:

  1. OPG (Orthopantomogram) Radiograph – This gives a view of the upper jaw, lower jaw, teeth and bone structures, sinuses, and base of the skull. This type of radiograph is very good at providing a general overview of the jaw and can act as an effective cancer screen. They are also helpful in planning extractions for a variety of teeth, including wisdom teeth. However, it does not accurately detect decay or Periapical Pathology.
  2. Lateral-Ceph Radiograph – This is a radiograph of the side of the face which is particularly useful in planning orthodontic treatment together with an OPG.
  3. CBTC CT Scan Radiograph – Dental CBCT uses CT technology to take up to 600 3D images of the patient from the neck up. During the procedure, a smaller version of a CT scanner rotates around the patient’s head, emitting X-rays in a cone shaped pattern. Having the ability to do 3D imaging is very useful for wisdom teeth extraction and planning implant placement in simple and complex implant cases, such as single tooth replacements with an implant crown or dental reconstruction using All-On-4 Implants. CBTC Scans can be used for other diagnostic procedures where an OPG or Peri-Apicals aren’t able to show the lesion.

To streamline the process and enhance your experience, Dental O So Gentle has their own Radiographic equipment. This means we can take the following Radiographs in house, so you don’t have to go anywhere else! We provide Peri-Apical, Bite-wings, Occlusal, OPGs and CBTC CT scans.
