When a Dental CT Scan Is Recommended

Do you need a dental CT scan? Dental care has seen significant advancements in recent years, leading to more efficient and accurate diagnoses and treatments. This technology of imaging allows specialized imaging techniques to be used to create very detailed 3D images of teeth, soft tissues, nerve pathways, and bone in the craniofacial region. This gives dentists so much capability. So when is this kind of scan recommended?  

What is it? 

A dental CT scan, or Cone Beam Computed Tomography (CBCT), uses X-ray technology to generate three-dimensional images of mouth and facial structures, soft tissues, nerves, and bones, all in a single scan. Unlike traditional X-rays, which provide two-dimensional images, the scans offer a more comprehensive view of everything in the mouth.

When is it recommended?

Implant planning

Before dental implants are placed, imaging may be required to assess the quality and quantity of the jawbone where the implant will be inserted. This information helps in precise planning, ensuring that the implant fits perfectly.

Diagnosis of temporomandibular joint disorder (TMJ)

The scan is often used to evaluate the temporomandibular joint, which connects the jawbone to the skull. If there is pain or dysfunction in this joint, a CT scan can help identify the underlying cause.

Orthodontic assessment

For individuals undergoing orthodontic treatment, a view of the orientation and structure of the teeth may be needed. It will help a lot in planning the movement of teeth, especially in the treatment of complex cases where conventional X-rays are not sufficient.

Evaluation of impacted teeth

If you have Impacted teeth, particularly wisdom teeth, it can lead to serious complications if not addressed properly. Getting a scan helps in visualizing the position of the impacted teeth in relation to nerves and other structures, aiding in careful planning of the extraction.

Assessment of sinus anatomy

The sinuses are located very close to the upper jaws and teeth. A dental CT scan can be used to evaluate the sinuses, especially if a patient is experiencing chronic sinus problems or before certain dental procedures, such as a sinus lift.

Detection of dental pathologies

Getting scanned may help in detecting and diagnosing tumors and other diseases that may be in the early stages. It can provide essential information on the size, extent, and involvement of the disease, aiding in proper treatment planning.

• Evaluation of facial trauma

In cases of facial trauma or fractures, a dental CT scan provides detailed 3D images that can help in understanding the full extent of the injury, guiding the surgeon in reconstructive procedures.

Advantages and limitations

Advantages:

• Precision: offers very detailed images, enabling more accurate diagnosis and planning.

• Less Radiation: Compared to regular medical CT scans, these scans typically expose the patient to less radiation than other ways of imaging.

• Quick: The scanning process is very quick, often completed in less than a minute. 

Limitations:

• Cost: These are typically more expensive than traditional X-rays when in cost comparison.

• Accessibility: Not all dental clinics have the equipment necessary to do a dental scan.

Preparing for the scan

Understanding what to expect and how to prepare can ease any anxiety that may arise during getting scans. Typically, the preparation is minimal:

• Patients may be asked to remove any metal objects they may be wearing, including all jewelry and eyeglasses, as these can interfere with the imaging.

• Sharing your complete medical and dental history with the radiologist or dentist ensures that all factors are considered before the scan.

• If you are pregnant or suspect you might be, inform your healthcare provider as soon as possible, as alternative imaging methods might be recommended.

Having a powerful diagnostic tool that has become integral in modern dentistry. They are typically recommended in complex dental cases, where traditional X-rays may not provide enough information. From implant planning to the diagnosis of dental pathologies, this technology helps dentists all around the world. 

Learn more from your dentist

You should discuss with your dental care provider if this type of scan is necessary for your specific situation. While the technology offers numerous advantages, including accuracy and speed, considerations such as cost and radiation exposure and its effects should also be part of the decision-making process. In the evolving field of dental care, a dental CT scan stands as a testament to how technology can significantly enhance patient care, offering precise and comprehensive solutions for various dental needs. It highlights the importance of individualized care and the continuous pursuit of excellence in dental diagnostics and treatments.
