Abstract

The purpose of this study was to compare and to find out the variability of head film measurements(landmarks ide ntification) between Fuji computed radiographic cephlometry and conventional cephalometry. 28 Korean adults were selected. Lateral cephalometric FCR film and conventional cephalometric film of each subject wa s taken. Four investigators identified 24 cephalometric landmarks on lateral cephalometric FCR film and conventional cep halometric film were statistically analysed. The results were as follows: 1. In FCR film and conventional film, coefficient of variation(C.V.) of 24 landmarks was taken horizontally and ver tically. 2. In comparison of significant differences of landmarks variability between FCR film and coventional film, horizonta l value of coefficient of variation showed significant differences in four landmarks among twenty-four landmarks, but ve rtical a value of coefficient of variation showed significant differences in sixteen landmarks among twenty-four landmar ks. FCR film showed significantly less variability than conventional film in 17 subjects among 20(4+16) subjects that sho wed significant difference.
