Orthopantomogram (OPG) and Lat Ceph (Lateral Cephalometric Radiograph) are special types of x-ray that take images of the lower face, teeth, jaw joints and maxillary sinuses. OPG generates a panoramic view of the teeth. It displays the number of teeth as well as their position and growth, and is useful to assess teeth within the gum such as wisdom teeth. Different from the small close-up X-ray shot taken at the dentists, OPG can also reveal any problems with the temporal and mandible bones and the joint connecting them. It is often requested for assessing wisdom teeth and the planning of orthodontic treatment.
Lat Ceph generates a side view image of the face and shows the facial contours and bones on a single film. Lat Ceph X-ray is also used for diagnosing and treating orthodontic problems.
Dental cone beam CT is a special type of X-ray technology which generates 3D images of dental structures, soft tissues, nasal cavity and sinuses, nerve paths and surrounding anatomy. It is useful in assessing impacted and extra teeth, planning dental implants, reviewing dental pathology and trauma, assessing temporomandibular joint (TMJ), and planning root-canal treatment and orthodontics. Cone beam CT provides extra information than regular dental or facial X-rays and allows for more precise treatment planning. Compared to conventional CT, cone beam CT gives lower radiation exposure but provides equally high-quality images.
