Diagnosis entails the complete evaluation of the patient’s dental condition from the clinical history, examination and special diagnostic tests. One of the most common and useful of tests in dental diagnosis is the taking of radiographs (X-Rays) of the teeth and/or jaws.

The main reasons for taking dental radiographs include:

1. Detection of early tooth decay, usually in the interdental areas, is possible only by radiographs. This would also include the detection of decay under existing restorations (fillings).
2. Detection and monitoring of any periodontal (gum) disease which may affect the bone supporting the teeth
3. Diagnosis of facial pain, especially in cases with extensive dental treatment
4. Impacted wisdom teeth causing pain and infection
5. Monitoring of the dental development in children
6. Evaluating any missing or unerupted teeth
7. Before implant placement
8. Diagnosis of infections or cysts in the jaw

Safety of dental X-Rays:

The amount of radiation received from a dental X-ray is extremely small. We get more radiation from natural sources, such as sunlight and minerals in the soil. With modern techniques and equipment, risks are kept to a minimum, and the X-rays are taken only when they are needed. However, pregnant women will probably avoid having X-rays taken, particularly in the first three months.

Types of X-rays: There are various types – some show one or two teeth and their roots. These are taken with a small film in the mouth. Some patients with a pronounced gag reflex may be uncomfortable with these intra-oral films. The panoramic radiograph shows the whole mouth, including all of the teeth and the bone structure that supports the teeth. A lateral cephalometric radiograph is a special skull X-Ray to assess the teeth and jaws in patients needing orthodontic treatment
