Are there any risks or side effects associated with CBCT scans?
CBCT (Cone Beam Computed Tomography) scans have revolutionized the field of dentistry, providing valuable three-dimensional imaging of the oral and maxillofacial structures. With its advanced capabilities, CBCT has become essential for accurate diagnosis and treatment planning in dental clinics worldwide. However, as with any medical imaging technique, it is natural to have concerns regarding the potential risks or side effects associated with CBCT scans. In this blog post, we will explore the safety profile of CBCT scans and address common questions surrounding their usage.
Understanding CBCT Scans
CBCT scans utilize a cone-shaped X-ray beam and a specialized detector to capture detailed images of the teeth, jawbone, temporomandibular joints (TMJ), and other anatomical structures. These scans provide comprehensive information that aids in the diagnosis of various dental conditions, including dental implants, orthodontic treatment, root canal therapy, and oral surgery.
Safety of CBCT Scans:
- Radiation Exposure: One of the primary concerns of any radiographic imaging is radiation exposure. However, CBCT scans emit a relatively low radiation dose compared to conventional medical CT scans. The radiation exposure from a CBCT scan is significantly lower than that of a medical CT scan, making it a safe and reliable imaging option in dentistry.
- Controlled Radiation: During a CBCT scan, the exposure is carefully controlled and limited to the specific area of interest. This targeted approach minimizes unnecessary radiation exposure, further enhancing the procedure’s safety.
- Short Scan Time: CBCT scans have a relatively short scan time, typically ranging from a few seconds to a minute. This reduces the duration of radiation exposure, minimizing the potential risks.
- Lead Aprons and Thyroid Collars: Dental clinics prioritize patient safety and take necessary precautions to minimize radiation exposure. Patients undergoing CBCT scans are often provided with lead aprons and thyroid collars, which act as protective shields, further minimizing radiation exposure to non-targeted areas.
Common Questions and Concerns:
- Pregnancy and CBCT Scans: Pregnant patients may have concerns about the safety of CBCT scans. While it is generally advisable to avoid unnecessary radiation exposure during pregnancy, the risk associated with a single CBCT scan is considered minimal. However, it is essential to inform your dentist if you are pregnant or suspect that you might be, as they can evaluate the necessity of the scan and take appropriate precautions.
- Allergic Reactions: CBCT scans do not involve using contrast agents or dyes, significantly reducing the risk of allergic reactions or adverse effects associated with such substances.
- Claustrophobia: CBCT scanners have an open design, which helps minimize anxiety and claustrophobic feelings that some patients may experience during the procedure. The available design ensures a comfortable and relaxed environment for patients.
CBCT scans have revolutionized dentistry, providing detailed and accurate diagnosis and treatment planning imaging. When performed by trained professionals and in adherence to safety protocols, CBCT scans are considered safe and reliable. The radiation exposure is minimal, and necessary precautions are taken to protect patients from unnecessary exposure. It is essential to consult with your dentist or oral healthcare provider to determine the necessity of a CBCT scan based on your specific dental condition and medical history.

Our experienced team of dentists and specialists is dedicated to providing personalized treatment plans while maintaining a comfortable and relaxing environment for our patients.
Q: Are CBCT scans safe for children?
A: CBCT scans can be performed on children for accurate diagnosis and treatment planning. However, radiation exposure is a concern, especially for young patients. Dentists take precautions to minimize radiation exposure, such as using appropriate shielding and adjusting the settings for pediatric patients, ensuring their safety.
Q: How often should CBCT scans be done?
A: The frequency of CBCT scans depends on the specific dental condition and treatment needs. Dentists carefully evaluate the necessity of a CBCT scan based on each patient’s case. CBCT scans are generally performed when conventional two-dimensional imaging is insufficient to gather the required information for diagnosis and treatment planning.
Q: Are there any specific post-scan instructions to follow?
A: In most cases, there are no specific post-scan instructions after a CBCT scan. Patients can continue with their routine and oral hygiene practices. However, if any particular instructions are necessary, your dentist will provide them based on your case.
Q: Can CBCT scans detect oral cancer?
A: CBCT scans capture detailed images of the teeth, jaws, and related structures. While CBCT scans may reveal specific abnormalities or suspicious lesions, they are not explicitly designed to detect oral cancer. If there are concerns regarding oral cancer, your dentist may recommend additional tests or refer you to an oral and maxillofacial specialist.
Q: What is the difference between CBCT and traditional dental X-rays?
A: CBCT scans provide three-dimensional images that offer a more comprehensive view of the oral and maxillofacial structures compared to traditional dental X-rays, which are two-dimensional. CBCT scans provide greater accuracy in diagnosing and planning treatments for complex dental conditions such as dental implants, orthodontics, and oral surgery.
Q: Can I undergo a CBCT scan if I have dental implants or other metal restorations?
A: Having dental implants or metal restorations does not typically interfere with undergoing a CBCT scan. The imaging technology can accurately capture the structures of interest, even in the presence of dental implants or metal restorations.
