A Cone Beam Computed Tomography (CBCT) scan, also known as a dental CT scan, is a specialized type of medical imaging technique used in dentistry to capture detailed 3D images of the teeth, jawbone, and surrounding facial structures. It is a valuable tool for diagnosing and planning various dental treatments. Here are some key points about CBCT scans:

1. Technology: CBCT uses a cone-shaped X-ray beam and a special detector to capture multiple 2D X-ray images from different angles around the head. A computer then reconstructs these images into a 3D representation.

2. Applications: CBCT scans are commonly used in dentistry for a range of purposes, including:

   • Implant planning: Precise assessment of the jawbone structure and available space for dental implants.
   • Orthodontic planning: Evaluation of tooth alignment, bone structure, and any impacted teeth.
   • Endodontic evaluation: Accurate diagnosis of root canal issues and the anatomy of the tooth’s root canals.
   • Oral surgery: Planning for procedures like wisdom teeth extraction, jaw surgery, and bone grafting.
   • TMJ assessment: Examination of the temporomandibular joints for TMJ disorders.
   • Diagnosis of pathology: Detection of cysts, tumors, and other abnormalities.

3. Advantages: CBCT scans offer several advantages, including high image quality, minimal radiation exposure (compared to medical CT scans), quick scan times, and the ability to provide detailed 3D images for precise treatment planning.

4. Procedure: During the CBCT scan, the patient is positioned in a special chair or machine, and the scanner rotates around the head. The process typically takes less than a minute, and the patient needs to remain still during the scan.

5. Safety: While CBCT scans do involve exposure to ionizing radiation, the dose is relatively low compared to medical CT scans. The benefits of accurate diagnosis and treatment planning generally outweigh the risks associated with radiation exposure.

6. Interpretation: The 3D images obtained from the CBCT scan are usually interpreted by a dental specialist, such as an oral and maxillofacial radiologist or a dentist, who can provide a detailed assessment and make treatment recommendations.

CBCT scans have revolutionized the field of dentistry by allowing for more accurate and efficient treatment planning and diagnosis. Dentists and oral surgeons use these scans to provide better patient care and ensure successful outcomes in various dental procedures.
