Summary A comparison between bone height scores from long‐cone paralleling radiographic surveys and orthopantomographs (Panex‐EC) of forty‐one patients was made. Intra‐examiner reliability and inter‐examiner objectivity of the measuring method (Schei ruler) proved to be very good (r = 0.954 and r = 0.923 respectively for the intra‐oral surveys; r = 0.928 and r = 0.916 respectively for the orthopantomographs). Distribution and frequency of the non‐measurable surfaces were evaluated. In each technique an attempt was made to discern the main cause of non‐measurability: overlapping of adjacent structures, absence of the surface and absence of the apical region on the image. For twenty of the thirty‐six surfaces significant differences were found between bone height scores for corresponding surfaces in the long‐cone survey and in the orthopantomograph. In periodontal, prosthetic and conservative dentistry the long‐cone paralleling technique should be considered as the best radiographic technique.
