Abstract

Background. The method of using panoramic radiographic images to obtain numerical data on the condylar guidance angle has been described in the literature.
Objectives. The aim of the study was to verify the reproducibility of this technique.
Material and Methods. One panoramic radiographic image was randomly chosen from a group of 191 images. The digital image was converted to analog and printed. The study involved 21 dentists, who positioned 4 dots on each side of the image (the orbitale and the porion, as well as the most superior and the most inferior points of the jaw’s articular surface). The points on each side were connected with 2 lines, A and B. To evaluate the accuracy of the lines, the equation of the straight lines was calculated and their slopes compared. The condylar guidance angle between the lines was calculated.
Results. The spread of the results for the condylar guidance angle on the right side was 30 degrees; on the left side it was more than 40 degrees. The SD for the slope of line A was 0.01 on both sides. The slope of line B varied from 0.25 to 0.34.
Conclusion. The use of panoramic images to obtain the condylar guidance angle is not recommended in clinical use.
