A standard periapical X-ray delivers about 5 microsieverts. A CBCT scan delivers 20 to 200 microsieverts depending on the field of view — roughly equivalent to 4 to 40 periapical films, or one to ten days of natural background radiation. By comparison, a medical CT of the head delivers approximately 2,000 microsieverts. CBCT is specifically designed to provide maximum diagnostic information at the lowest feasible dose for dental applications.

You will not feel anything during the scan. You stand or sit with your chin resting on a small support while the scanner arm rotates quietly around your head for 12 to 20 seconds. There is no enclosed space, no injection, and no discomfort. The only requirement is holding still so the image is sharp.

When a two-dimensional image cannot answer the clinical question. Common reasons include implant planning where bone dimensions must be measured precisely, locating a root canal in a tooth with unusual anatomy, evaluating the proximity of an impacted wisdom tooth to the nerve, assessing TMJ joint morphology, and identifying the extent of a cyst or lesion within the jawbone.

CBCT imaging is generally deferred during pregnancy unless there is a dental emergency that cannot be managed without three-dimensional imaging. If you are pregnant or suspect you may be, inform the clinical team before any radiographic imaging. Alternative diagnostic approaches will be used whenever possible.

The scan data is available on screen within two to three minutes after the exposure. Dr. Ostovar or Dr. Gvozden typically reviews the images with you during the same appointment. If a written interpretation report is being prepared for a referring office, it is usually completed and sent within one to two business days.

Coverage varies by plan and by the clinical reason for the scan. Many dental insurance plans cover CBCT imaging when medical or surgical necessity is documented — for example, implant planning, impacted tooth evaluation, or endodontic diagnosis. The ADSC billing team verifies your benefits in advance and provides an out-of-pocket estimate before the scan is taken.

Medical CT scanners use a fan-shaped beam that captures slices one at a time and are designed for soft-tissue imaging throughout the body. CBCT uses a cone-shaped beam that captures an entire volume in one rotation and is optimized for hard-tissue (bone and teeth) imaging at lower radiation doses. For dental purposes, CBCT provides superior bone detail at a fraction of the dose and cost of a medical CT.

CBCT can reveal radiolucent and radiopaque lesions within the jawbone, including cysts, tumors, and other pathology. While CBCT does not diagnose the specific type of lesion — a biopsy is needed for that — it defines the size, borders, and relationship to surrounding structures, which guides surgical planning and referral decisions. Incidental findings on CBCT are reviewed with the patient and communicated to relevant medical providers.

The three-dimensional data shows exactly how much bone is available in height, width, and density at the proposed implant site. It reveals the position of the inferior alveolar nerve, the maxillary sinus floor, and adjacent tooth roots. This information is imported into surgical planning software where the implant size, angle, and depth are mapped digitally, and a custom surgical guide is 3D-printed to transfer that plan into the mouth with sub-millimeter accuracy.

Only when the clinical question cannot be answered with lower-dose imaging. Common pediatric indications include impacted or supernumerary teeth, trauma evaluation, and orthodontic assessment of jaw growth patterns. When a child does need CBCT, the field of view and exposure settings are reduced to minimize dose while capturing the necessary anatomy.

Yes. CBCT data is stored in DICOM format, the universal standard for medical imaging. ADSC can export your scan to a USB drive or transmit it digitally to any dental or medical office. The data belongs to you and can be shared with any provider involved in your care.

Not always. A panoramic X-ray provides a broad screening view of both jaws in a single image at very low dose and cost, and it is adequate for many diagnostic purposes — evaluating overall tooth development, screening for gross pathology, and assessing third molars at an initial level. CBCT is indicated when the clinical question requires three-dimensional detail, precise measurements, or evaluation of structures that overlap on a two-dimensional image.

There is no fixed limit on CBCT frequency, but the ALARA principle applies — as low as reasonably achievable. Scans are taken only when clinically necessary. Most patients need one CBCT scan per treatment episode. Some complex implant cases may require a pre-surgical planning scan and a post-placement verification scan, which is well within safe cumulative dose limits.

Remove eyeglasses, earrings, necklaces, hairpins, hearing aids, and any removable dental appliances such as retainers or partial dentures. Metal objects create artifacts in the scan that can obscure anatomical detail. The clinical team will remind you before positioning.

The fee depends on the field of view — a small-volume scan of a single tooth area costs less than a full-arch bilateral scan. The front desk provides exact pricing when you schedule. Many patients find that the cost of a CBCT scan is offset by the surgical precision it enables, which reduces operative time, complications, and the need for revision procedures.
