The Benefits of Cone Beam CT?
Dental cone beam computed tomography (CT) is a special type of x-ray machine used in situations where regular x-rays are not sufficient. It is especially valuable in the diagnosis of infected root canals, where the periapical lesion does not show in 2-dimensions. Since root canal teeth are dead, they may not hurt and infections can go undiagnosed for years. We suggest all root canal teeth be checked with a CBCT.
It is not used routinely because the radiation exposure from this scanner is significantly more than regular dental x-rays. This type of CT scanner uses a special type of technology to generate three dimensional (3-D) images of dental structures, soft tissues, nerve paths and bone in the craniofacial region in a single scan. Images obtained with cone beam CT allow for more precise treatment planning.
You should wear comfortable, loose-fitting clothing.
Metal objects, including jewelry, eyeglasses, dentures, and hairpins, may affect the CT images and should be left at home or removed prior to your exam. You may also be asked to remove hearing aids and removable dental work.
Cone beam CT provides detailed images of the bone and is performed to evaluate diseases of the jaw, dentition, bony structures of the face, nasal cavity, sinuses, and especially chronic infected root canals.
