Gold standard is that 95% of digital radiographs (90% of wet films), are recorded as 'diagnostically acceptable' (Grade 'A')”. 5.2. For film images an appropriate light box and magnifier should be used for viewing, for digital images low ambient light is required. 5.3.
When using more than one type of radiograph e.g. intra oral and panoramic images, results should be reported separately. The target percentages of images rated as diagnostically acceptable are: Digital images – not less than 95% Film images – not less than 90%
Acceptable image density and contrast. Free of patient preparation, technical and exposure errors. An optimal panoramic radiograph should be free from errors related to patient preparation, technique, or exposure.
Some of the things your dentist will examine in your dental X-rays include:
- Position, size, and number of teeth
- Changes in the root canal
- Bone loss in the jaw or facial bones
- Bone fractures

Radiographs can be categorised for image quality as follows: A =
Diagnostically acceptable. No errors or minimal errors in either patient preparation, exposure, positioning, image (receptor) processing or image reconstruction and of sufficient image quality to answer the clinical question. N = Diagnostically not acceptable.
