Indiana University-Purdue University Indianapolis (IUPUI) / The purpose of this study was to determine whether angular and
linear measurements from tracings of a Panorex radiograph provide a
valid comparison to bony relationships identified on the lateral cephalometric
headplate of the same individual.
A pilot study was performed on a dried skull to identify selected
skeletal landmarks on Panorex radiographs. Using these landmarks,
fifteen measurements of bony relationships of the head were completed
on each radiograph. Values obtained on a lateral headplate were compared
with measurements on the same patient's Panorex radiograph for
a group of forty-eight children.
The data were recorded on standard IBM punch cards and submitted
for statistical analysis to the Research Computation Center of
Indiana University-Purdue University at Indianapolis.
The data support the conclusion that angular and linear measurements
from a tracing of a Panorex radiograph cannot be compared
directly or in a proportional manner to similar measurements from a
tracing of a lateral headplate of the same individual. Although there
was significant correlation of comparative measurements for the
sample group as a whole, there was wide variation from individual to
individual.
