Dental Cone-beam computed tomography systems (CBCT) is a variety of the Traditional computed Tomography (CT) systems only modified and improved to capture data as it rotates around a patient using an X-ray beam, then this data is used to reconstruct a three-dimensional image showing the patient’s anatomy. The CBCT provides a comprehensive radiology dental report containing detailed multi-page interpretations, images and illustrations that have accurate measurements and highlight your requested area of interest to effectively use imaging technology to give the best treatment.
These systems are used widely by dental related professions for various clinical purposes including implanting a dental plan, checking out abnormal teeth, cleft palate assessment, and diagnosis of cavities, root canal and dental trauma. The Dental CBCT gives a report reviewing around the oral and maxillofacial region for a quick analysis of the images.
A patient should remove everything that might corrupt imaging and this includes metal objects like jewelry or eyeglasses. However, artificial dental work should be brought to the radiologist for examination. It is also necessary that the examiner checks if the person qualifies for the CT scan. When taking this scan the patient should wear comfortable, loose-fitting clothing to the examination. The cone-beam CT gives room for a more precise treatment plan of the infected parts. The detailed images of the parts provide the full diagnostic analysis including evaluation of the patient’s soft tissue parts of his or her anatomy like lymph nodes, glands and nerves.
The Dental CBCT is better since it provides lower radiation exposure compared to other varieties of CT resulting in better quality of the images. A scan gives a variety of views that provide an in-depth evaluation of the patient’s anatomy. No radiation is left in the patient’s body but it still leaves a risk of obtaining cancer from the radiation, though this cannot be compare to the conventional dental X-ray.
The CBCT scans are painless accurate and does not have immediate side effects. These scans are not advised to be undertaken in pregnant women and young children. However these scans can be taken in children only with low-dose technique.
The cone beam CT’s apparatus is made to rotate around the head in a complete 360-degree rotation while taking multiple images from different angles and views, then it uses these images to create a single three dimensional image. The radiation source and detector are placed strategically in a way that it rotates in unison with the C-arm. In one rotation a CBCT scan generates over 150 two dimensional images and then it digitally processes a three dimensional image. This process therefore takes about twenty seconds to one minute.
This procedure is useful for more complicated cases involving impacted teeth planning, accurate placement of dental implants, evaluation of the mandibles, cephalometric analysis and in some cases locates the source of pain or infection, evaluation of paranasal sinuses and temporomandibular joints for example is inclusive of lateral cephalometric, panoramic and all angular views of the maxillofacial complex of the mandibular joints.
