The purpose of this study was to compare & to find out the variability of head film
measurements(landmarks identification) between Fuji computed radiographic cephalometry
and conventional cephalometry.
28 Korean adults were selected. Lateral cephalometric FCR film and conventional
cephalometric film of each subject was taken. Four investigators identified 24
cephalometric landmarks on lateral cephalometric FCR film and conventional
cephalometric film. The comparable measurements between lateral cephalometric FCR
film and conventional cephalometric film were statistically analysed.
The results were as follows.
1. In FCR film & conventional film, coefficient of variation (C.V.) of 24 landmarks
was taken horizontally & vertically. There is no significant difference of rank order of
landmarks in C.V. between two films.
2. In comparison of significant differences of landmarks variability between FCR film
& conventional film horizontal value of coefficient of variation showed significant
differences in four landmarks among twenty-four landmarks,
but vertical value of coefficient of variation showed significant differences in sixteen
landmarks among twenty-four landmarks.
FCR film showed significantly less variability than conventional film in 17 subjects
among 20(4+16) subjects that showed significant difference.
