Interpretation Terminology
Interpret
An interpretation is to offer an explanation. An image interpretation is an explanation of what is viewed on a dental image and the ability to read what is revealed by a dental image.
Diagnosis
Diagnosis is the identification of a disease by examination or analysis. In the dental setting, the dentist is responsible for establishing a diagnosis. Other members of the dental team are restricted by law from rendering a diagnosis. Dental radiographers must be careful to stay within their scope of practice when interpreting dental images.
Importance of Interpretation
Much information about the teeth and supporting bone is obtained from image interpretation. All dental images must be carefully reviewed and interpreted. Image interpretation is of paramount importance to the dental professional and plays a vital role in the detection of diseases, lesions, and conditions of the teeth and jaws that cannot be identified clinically.
Guidelines
There is a difference between interpretation and diagnosis, and the dental radiographer needs to be familiar with each.
Who Interprets Images?
Any dental professional with training in interpretation can examine radiographs.
This will involve identification of:
- Normal anatomy
- Dental restorations, dental materials, and foreign objects
- Dental caries
- Periodontal disease
- Traumatic injuries, pulpal lesions and periapical lesions
- Common artifacts and errors
The dental hygienist and dentist are taught how to interpret clinically, the dental assistant however, may or may not be trained.
Interpretation versus Diagnosis
In the dental setting, the terms interpretation and diagnosis are often confused. Both have very different meanings and should not be used synonymously.
Interpretation |
Interpretation refers to an explanation of what is viewed on the dental image. |
Diagnoses |
Diagnoses refers to identification of disease by examination or analysis.
The final interpretation and diagnosis are the responsibilities of the dentist. Dental hygienists and dental assistants are restricted by law from rendering a diagnosis. |
A diagnosis is made by the dentist after a thorough review of the medical history, dental history, clinical examination, radiographic examination, and clinical or laboratory tests.
When and Where Are Images Interpreted?
It is best to have images taken at the beginning of the appointment and interpreted immediately after mounting in the presence of the patient. Suspicious or questionable areas can be examined by the dental professional to obtain additional information or confirm a suspected problem. It is important to remember that images are taken to benefit the patient.
Interpretation and Patient Education
Images may be an educational tool in the dental setting. The patient may be educated through discussion of normal findings on dental images and specific problems and areas of concern may be identified. Educating patients using dental images can help everyone work together as a team.
