Indiana University-Purdue University Indianapolis (IUPUI) / The purpose of this study was to determine the relative
accuracy of a panoramic radiographic method in the determination
of unerupted tooth mass.
Four types of radiographic films were made for each of
fifty children. The diameters of the unerupted permanent
cuspids and bicuspids were measured to compare and assess the
degree of linear distortion between the types of radiographs
when obtained under routine clinical conditions. The experimental
Panorex film was made with the patient positioned
eccentrically, but all other radiographic procedures used in
this study followed the techniques recommended by the Indiana
University School of Dentistry Department of Radiology.
The greatest mesial-distal dimensions of the unerupted
permanent cuspids and bicuspids were recorded to the nearest
0.1 millimeter. The data were recorded on standard IBM
punch cards and submitted for summation and statistical analysis
to the Research Computation Center of Indiana University-
Purdue University at Indianapolis.
Although magnification was reduced considerably, the
experimental technique was demonstrated not to be of sufficient
and consistent accuracy to be applicable in the determination
of tooth mass for the mixed dentition analysis.
