  • Title: Assessment of mandibular condyle position: a comparison of transcranial radiographs and linear tomograms.
    Author: Pullinger A, Hollender L.
    Journal: Oral Surg Oral Med Oral Pathol; 1985 Sep; 60(3):329-34. PubMed ID: 3862048.
    Abstract:
    Transcranial radiographs are frequently used to assess condyle-fossa relationships. However, their validity in representing condyle position has been questioned. Intermethod comparisons were performed between methods assessing condyle position by subjective evaluation and by linear and area measurement of the interarticular space. Linear measurement of the subjective closest anterior and posterior interarticular space and subjective evaluation were the mutually preferred methods in both transcranial radiographs and tomograms. Statistically significant correlations were shown (p less than 0.05) for condyle position between pairs of clinical transcranial radiographs and linear tomograms of the same temporomandibular joints. However there was a qualitative concordance in assessed posterior concentric and anterior positions in only 80% of the pairs, and a full concordance in the degree of condylar displacement was found in only 60% of the cases. Although still clinically helpful, the use of transcranial radiographs to monitor small changes in condylar position relative to the tomogram was questioned.
