The magnification factor of each cephalogram
was standardized at 8%.
Lateral scanned cephalogram
were evaluated twice by the same researcher with an interval of one week difference.
Regarding image diagnosis, a lateral cephalogram
is part of early orthodontic documentation, and its assessment has allowed orthodontists to observe possible upper airway obstructions.
Hand wrist panoramic radiographs and cephalogram
of 85 patients were taken.
With the soft tissue screen removed, a lateral cephalogram
was taken with X-ray exposure at 63 kV, 110 mA for 0.
Cephalometric landmarks used were identified and reference planes were drawn on tracing of lateral cephalogram
Static records such as study models, lateral cephalogram
, and patient photographs can give limited insight for diagnosis and planning treatment, especially in such cases.
Many times the image of the atlas vertebrae may be distorted or obscured in the lateral cephalogram
which may at times give an illusionary image.
To determine the skeletal deformity lateral cephalogram
OPG were taken (fig-2) and model surgery was done.
Vertebral analysis of a lateral cephalogram
has been shown to be as valid as the hand-wrist bone analysis, with the advantage of reducing the radiation exposure to growing subjects.
x- rays were taken with the teeth in occlusion.
The aim of this study was to assess the values of gonial angle on orthopantomogram (OPG) and correlate them with the respective values on lateral cephalogram
in order to determine the diagnostic capability of OPG for vertical facial pattern.
