Dental Cone Beam CT (CBCT)

Cone Beam Computed Tomography (CBCT) is an advanced imaging technology that produces detailed three-dimensional (3D) images of the teeth, oral and maxillofacial region, and surrounding structures. Unlike traditional two-dimensional dental X-rays, CBCT scans provide a comprehensive view, enabling precise diagnosis and treatment planning.

CBCT works by rotating around the patient's head, capturing multiple images from different angles. These images are then reconstructed into a 3D model using specialized software. This technology is particularly useful in various dental applications, such as dental implant planning, endodontics (root canal treatment), orthodontics, and oral surgery.

The main difference between Cone Beam Computed Tomography (CBCT) and standard X-rays is the type of images they produce. Standard X-rays create flat, 2D pictures that show just the height and width of your teeth and jaw. CBCT, on the other hand, takes many pictures from different angles and combines them into detailed, three-dimensional images. This 3D view helps dentists see everything more clearly, which is especially useful for complex procedures like placing dental implants or planning orthodontic treatments. While CBCT uses slightly more radiation than standard X-rays, it provides a much clearer and more complete picture of your mouth.

An X-ray that goes around the patient's head, commonly used for general dental exams, is likely a panoramic X-ray, not a CBCT. Panoramic X-rays provide a flat (2D) image of the entire mouth and surrounding structures, making them suitable for routine dental exams due to their lower radiation dosage.

In contrast, CBCT scans are only prescribed when there is a specific concern or purpose, such as diagnosing pathology or planning complex procedures. CBCT creates a detailed 3D image by rotating around the patient's head to capture multiple X-ray images from different angles. This technology is particularly useful for precise diagnoses and treatment planning, including dental implants and impacted teeth, offering more detailed information compared to panoramic X-rays.

CBCT scans represent a significant advancement in dental care. They offer highly detailed 3D images of the teeth, jaw, and surrounding structures, providing dentists with an exceptionally clear and comprehensive view. This enables precise diagnosis and effective treatment planning. The scanning process is efficient and comfortable, typically taking less than 1 minute. Its accuracy helps to prevent complications during procedures such as dental implants, root canals, and orthodontics. Overall, CBCT technology greatly enhance the quality of dental care by facilitating accurate diagnoses, optimal treatment planning and ideal outcomes.

CBCT is typically recommended when standard dental X-rays don't provide enough information for a clear diagnosis or treatment planning. It's especially useful for complex cases like:

• Dental Implants: CBCT helps assess bone quality, quantity, and location for precise implant placement.

• Orthodontics: It provides detailed views of teeth and jaws to plan orthodontic treatment, especially for impacted teeth or assessing root positions.

• Endodontics: CBCT aids in identifying root canal anatomy and complexities, helping to ensure thorough treatment.

• Complex Extractions: It assists in evaluating the surrounding structures and planning for safe removal of impacted or severely damaged teeth.

• TMJ Disorders: CBCT helps in evaluating the temporomandibular joint (TMJ) for issues like joint disorders or pain.

• Trauma and Pathology: It aids in diagnosing fractures, infections, cysts, and tumors in the jaws or teeth.

By providing 3D images, CBCT enhances diagnostic accuracy and treatment planning, ensuring patients receive the most effective and personalized care for their dental needs.

When undergoing a CBCT scan, you can expect a comfortable and quick procedure. First, you will be asked to remove any metal objects like jewellry or glasses that could interfere with the scan. Once ready to proceed, you'll stand still while a machine rotates around your head, capturing multiple X-ray images from different angles. During the imaging process, you'll be instructed not to move or swallow to ensure clear images. The process is painless and typically takes less than a minute.

After the scan, your dentist will use the images to assess anatomical structures in detail to identify pathologies or design surgeries. These results are crucial for making accurate diagnoses and planning appropriate treatments for your dental needs.

CBCT scans are generally safe and efficient. The cone beam design utilizes a low dose of carefully controlled radiation to effectively capture a large area of images. For most patients, the benefits of CBCT in accurate diagnosis and treatment planning outweigh the small risk of radiation exposure. Pregnant women and children are typically advised to avoid unnecessary X-rays, including CBCT, unless absolutely necessary.

At North Peace Dental and Implant Centre, we follow strict radiology guidelines to minimize radiation exposure:

• X-ray and CBCT equipment installation was designed by certified engineers to ensure safety.

• X-ray and CBCT equipment undergo inspection every 5 years.

• Radiation meters are worn by staff to confirm radiation levels and prevent leakage.

• All staff conducting X-rays or CBCT are trained and certified by the BC College of Oral Health Professionals.

• Lead aprons are used for all radiated procedures.

• X-rays and CBCT scans are only performed when medically necessary.

Overall, CBCT scans are considered safe when used appropriately by trained professionals for specific dental diagnostic purposes.
