CBCT Technology

We are pleased to announce the installation of a limited field, high-resolution cone beam computed volumetric tomography (CBCT) unit in our office. This limited field unit, the first in the region, provides three-dimensional radiographic images of the teeth and jaws, allowing greatly improved viewing of the maxillofacial skeleton.

While a thorough history and clinical examination are essential for the diagnosis of odontogenic pain, interpretation of periapical radiographs (PAs) is complicated by the background pattern of overlapping roots and anatomic structures such as the maxillary sinus and the zygomatic buttress. The use of computed tomography enables the evaluation of the true extent of lesions and their spatial relationship to important anatomic landmarks. A recent study by Low, et al, published in the Journal of Endodontics, has demonstrated a 34% improvement in visualizing lesions of endodontic origin when compared to PA radiography alone.

Radiation dose to the patient is another benefit of CBCT imaging. While a medical CT image of the maxilla and mandible is about 2.0 mSv or the equivalent of 243 days of background radiation, a limited field CBCT will require only 0.005 – 0.038 mSv or the equivalent of 1 – 5 days of background radiation, depending on the area of interest.

We hope that we may be of service to you and your patients who may need an evaluation of their dentition to rule out odontogenic pathosis.
