Sažetak

The objective of this study was to evaluate the precision of the vertical dimensional measurements on orthopantomographic images, and therefore to evaluate their dimensional reliability. Different distances denoted by metal markers were measured on 25 dry mandibles. The same measurements were repeated on panoramic radiographs o f those mandibles and the results were statistically analysed. The calculated magnification factors for the vertical measurements were, in general, smaller than the manufacturer of the X-ray device declares, although the difference was not statistically significant for the most variables. Opposite to some opinions, our results reveal that the vertical measurements on orthopantomograms are precise enough even in the anterior region of the mandible, if the mandibles are adequately positioned and encompassed in the focal through of the machine.
