An OPG is a panoramic or wide view x-ray of the lower face, which displays all the teeth of the upper and lower jaw on a single film. It demonstrates the number, position and growth of all the teeth including those that have not yet surfaced or erupted. It is different from the small close up x-rays dentists take of individual teeth. An OPG may also reveal problems with the jawbone and the joint which connects the jawbone to the head, called the temporomandibular joint or TMJ. An OPG may be requested for the planning of orthodontic treatment, for assessment of wisdom teeth or for a general overview of the teeth and the bone which supports the teeth.
Lateral Cephalometic View
A Lat Ceph is a lateral or side view x-ray of the face, which demonstrates the bones and facial contours in profile on a single film. Lat Ceph x-rays are usually used in the diagnosis and treatment of orthodontic problems.
Show the whole tooth — from the crown, to beyond the root where the tooth attaches into the jaw. Each periapical x-ray shows all teeth in one portion of either the upper or lower jaw. Periapical x-rays detect any unusual changes in the root and surrounding bone structures
