Background. Radiographic diagnostics in dentistry is one additional examination which facilitates an accurate clinical diagnosis and, as a result, the initiation of appropriate treatment. Despite various limitations, functional panoramic radiograph (OPG) images of the temporomandibular joints (TMJ) provide a great deal of valuable information and seem to be the first-choice modality in the diagnosis of temporomandibular disorders.
Objectives. The aim of this study was to evaluate any relationship between the range of mouth opening and the condyle positions during this movement, on the basis of functional OPG images.
Material and Methods. To evaluate the distance between the condyle positions, 10 functional OPG images of the TMJ were used. The relationship between the measurements taken during clinical examination of the patients and the measurements obtained from functional OPG images were evaluated. The research hypothesis assumed that there was a positive correlation between the clinical range of mouth opening and the measurement of condyle movement from a centric occlusion position to its maximum opening.
Results. The analysis of measurements showed no statistical correlation between the distances between the condyle positions obtained from radiographic images and clinical measurements of the range of mouth opening.
Conclusion. In young, healthy patients without clinical symptoms of TMJ dysfunction, functional OPG images of the joint should not be compared with the range of mandibular opening.
