[Comparative study concerning the magnification of anterior permanent teeth of the upper jaw in the Status-X radiograph and in the orthopantomograph].

Abstract

Measurements of the mesiodistal diameters and the total length of anterior permanent teeth of the upper jaw were performed in 82 status-X radiographs and in 82 orthopantomographs of the same patients, in order to determine the difference of magnification in the two kinds of radiographs. The findings proved that the difference of magnification of the mesiodistal diameters ranges from 82.08% to 90.14% and of the total length ranges from 65.58% to 81.17%. On the whole, the highest difference of magnification of the mesiodistal diameters was noticed in the central incisors while the lowest values were obtained in the canines. Also, the highest difference of magnifications of the total length was noticed in the canines while the lowest values were obtained in the central incisors.
