ADA reports on cone beam CT in August JADA

August 06, 2012

By Jean Williams, ADA News staff

In the August issue of The Journal of the American Dental Association, the ADA Council on Scientific Affairs presents a new advisory statement addressing the use of cone beam computed tomography in dentistry.

CBCT provides three-dimensional views of dental and associated maxillofacial structures with high dimensional accuracy; the technology has expanded the field of oral and maxillofacial radiology, according to the statement.

“Consistent with its mission to serve as a primary resource on the science of dentistry, the ADA Council on Scientific Affairs reviewed the current science, guidance and other resources available from professional organizations to prepare this advisory statement of principles for the safe use of CBCT in dentistry,” the statement says.

The statement provides essential principles for consideration in the selection of CBCT imaging for individual patient care with an overall emphasis on the practitioner's primary ethical obligation to protect patients from harm including: weighing the potential clinical benefits and risks of CBCT versus other options; the importance of keeping radiation exposure as low as reasonably achievable (ALARA); and establishing a facility quality control program to maintain compliance with applicable local, state and federal requirements.

Additionally, the statement advises that CBCT imaging should not be performed for screening purposes and additional considerations should be weighed before use with children and adolescents.

The draft recommendations underwent a broad stakeholder review process, resulting in significant input from other ADA councils and the several leading dental and health organizations to develop the final statement. The ADA expresses its appreciation to those organizations in the statement.
