Radiological Examination

1. What is Radiological Examination in Dentistry?

Radiological examination in dentistry is an imaging method used to diagnose and plan treatments for dental, oral, and jaw-related issues. It provides detailed information about the roots of teeth, jawbones, and surrounding tissues.

 

2. Types of Radiological Imaging in Dentistry

• Periapical X-ray: Provides detailed images of individual teeth, including the roots and surrounding areas. It is used to detect root infections, cysts, and abscesses.

• Panoramic X-ray: Offers a broad view of the entire mouth (upper and lower jaws). It is used to identify impacted teeth, jaw fractures, tumors, and general tooth alignment.

• Bitewing X-ray: Captures images of both the upper and lower teeth, mainly used to detect cavities and examine tooth surfaces.

• Cone Beam Computed Tomography (CBCT): A 3D imaging method used for implant planning, analysis of jaw structures, and evaluation of complex dental problems.

​

3. Why is Dental Radiology Performed?

• Detection of Cavities: Useful for detecting cavities between teeth and near the gum line.

• Root Canal Treatment: Evaluates infections or inflammation in the tooth root and surrounding tissues.

• Identification of Impacted Teeth: Used to assess the position and impaction of wisdom teeth.

• Implant Planning: Essential for analyzing bone structure and planning the placement of dental implants.

• Periodontal Disease: Helps assess bone loss and the severity of gum disease.

​

4. How is it Applied?

Radiological examination is usually a quick and painless process. The dentist selects the appropriate imaging method and positions you accordingly. Small X-ray devices or larger panoramic machines may be used. The procedure lasts anywhere from a few seconds to a few minutes.

​

5. Procedure Process

• Preparation: No special preparation is typically required. However, for panoramic X-rays, a lead apron is often used.

• Imaging: It is important to remain still during the procedure. The X-ray device captures the targeted area.

• Results: The images are available immediately either digitally or as film, and the dentist will evaluate them.

​

6. Radiation Exposure

Dental radiographic imaging methods involve very low levels of radiation. Modern digital X-ray machines emit significantly less radiation compared to traditional devices. Dentists only perform these procedures when necessary and minimize radiation exposure.

​

7. Who is Suitable for Radiological Examination?

Radiological examinations are safe for most patients. However, pregnant women should inform the dentist. While dental X-rays use low radiation, precautions are taken, and imaging is generally avoided during pregnancy unless it’s an emergency.

8. Post-Radiological Examination Care

No special care is required after a radiological examination. The dentist will review the images and provide a diagnosis, followed by a treatment plan. Before starting treatment, the dentist carefully examines the images.
