Aim. The aim of this investigation was to assess differences of height of mandibular bone ridges, which were measured on determined referent lines toward mandibular base, and on the separate line positioned onto low edges of selected panoramic radiographs. Material and methods. 7 panoramic radiographs of dentate men and 9 panoramic radiographs of natural dentition women, aged from 25 to 56 years were selected. Panoramic dental-films were from the same serial (Kodak T-MATG, USA) using roentgen apparatus (Orthopantomograph 10, Siemens, Germany). There were two procedures of measurements: determination of mandibular corpus and bone ridge height on the line determined between the 1st and the 2nd lower molars toward referent line drawn along a contour of mandibular base, and determination of mandibular corpus and bone ridge height on the basis of measurements of segment of the line determined from lower edge of panoramic radiograph to ridge between the 1st and the 2nd lower molars. Results. Pearson's correlation coefficient (r=0.207) was not significant for all measured heights of mandibular corpus and bone ridges. Conclusion. The results of this investigation did not confirm statistically significant differences of numerical values of bone ridge heights, regardless the fact that there were differences of inclination of lines, used in measurement of heights. .
