Abstract
The reliability of two traditional and two computerized cephalometric
analyses was comparatively examined. Thirty radiograms were analysed twice with all four analyses. On 18 selected variables of each o f the analyses average differences and method errors were evaluated. The results indicate that there are no significant differences between the traditional, indirect method with conventional cephalometric tracing and direct computer analysis. The examinations undertaken with an indirect computed method, during which the cephalometic landmarks are fixed on the screen of the computer, revealed significant differences. The obtained values indicating the inclination of the incisors were found to differ the most. The least significant differences o f all cephalometric methods was found in linear landmarks, specifying the upper and lower incisor position.
