Cone-Beam Computed Tomography (CBCT) is an advanced imaging technique, highly regarded especially in dental and otolaryngological diagnostics. It provides precise three-dimensional images, allowing for more accurate visualization of anatomical structures than traditional 2D images. CBCT is also used in the youngest patients. However, parents often have questions about the potential harmfulness of computed tomography in children. Is tomography safe for a child? How to prepare a child for tomography to ensure the examination is performed correctly and safely?
CBCT in Children – When Is It Necessary?
CBCT offers exceptional capabilities in accurately imaging the facial skeleton, teeth, paranasal sinuses, and temporomandibular joints. Computed tomography in children may be necessary in cases of:
Diagnosis of Malocclusions: CBCT enables orthodontists to plan treatment precisely by assessing the skeletal system, the position of impacted teeth, and evaluating the temporomandibular joints.
Assessment of Injuries: In cases of facial injuries, CBCT can provide detailed information about fractures or other damage to bone structures.
Evaluation Before Applying Orthodontic Appliances: Orthodontists often order a CBCT examination before putting on braces to precisely assess tooth structure, root positions, and the relationship of teeth to neighboring bone structures.
Sinus Diagnostics: For chronic sinus problems, CBCT helps identify the source of the issue, which is extremely helpful in planning possible surgical interventions.
Surgical Procedure Planning: For procedures such as extraction of impacted teeth or correction of facial skeletal defects, CBCT provides surgeons with an accurate image of anatomical structures.
Detection of Cysts, Tumors, or Other Abnormalities: CBCT allows for a detailed assessment of bone structures, which is useful in diagnosing abnormalities within them

Recommendations for Performing CBCT in Children
To minimize the risks associated with radiation in children while benefiting from the advantages of CBCT technology, several recommendations have been developed for children, doctors, and parents:
ALARA Principle: This principle stands for “As Low As Reasonably Achievable.” Doctors should only order a CBCT examination when absolutely necessary. They should always strive to use the minimal radiation dose.
Limiting the Scanning Area: Whenever possible, only scan a strictly defined area to limit radiation exposure. Modern CBCT devices allow for selecting the size of the scanning field, which is crucial in pediatric diagnostics.
Using Appropriate Protective Shields: To ensure safety during tomography in children, appropriate shields like lead aprons are especially important to protect other body areas from radiation. At Skanai, we have a special, easy-to-wear apron for children, ensuring their safety during the examination.
Choosing Specialists and Equipment Adapted for Children: CBCT examinations for children should be performed in facilities equipped with modern equipment offering the lowest possible radiation doses and suitably adapted for performing computed tomography in children. It’s also essential that the medical staff has experience conducting such examinations in young patients.
CBCT examinations in children can be a very important element in the precise diagnosis of dental, orthodontic, or otolaryngological conditions. However, due to the risks associated with radiation, imaging diagnostics in children should be done with great caution and only in justified cases. Minimizing the radiation dose, selecting appropriate equipment, and using protective shields are crucial in avoiding risks. This allows for effective and safe computed tomography in children. It’s also important to choose a reputable facility. We encourage you to check out our offer: Skanai – CBCT Computed Tomography in Krakow. However, it should be emphasized that tomography in children should only be ordered when it is truly necessary and other diagnostic methods will not give the expected results.
