A method for quantitatively determining temporomandibular joint bony relationships.

The spatial relationship of the mandibular condyle to the temporal component of the TMJ is determined quantitatively from lateral tomograms using a new method of measuring specific areas of the joint space. Condyle position along the posteroanterior axis of the joint is expressed as a ratio of the posterior joint space area divided by the anterior joint space area (the P/A ratio). A description of the method, as used in a clinical evaluation of 50 asymptomatic tMJs, and a statistical evaluation of the method's reproducibility and accuracy are given. The method was found to have both high reproducibility and high accuracy.

Normal TMJ bony relationships in centric occlusion.

In a preliminary investigation, condyle-temporal bone spatial relationships were determined quantitatively in 50 asymptomatic TMJs (25 subjects) by making area measurements of the posterior and anterior portions of the joint spaces. For both right and left sides, the numerical expression of the joint relationship indicated that the condyle is normally centered in the joint to a very high degree. Standard deviations around the mean joint relationship values were large, however, which suggests that the posteroanterior variation of condyle positions in asymptomatic TMJs is greater than commonly thought. In addition, there was only mild correlation between individual joint relationships on right and left sides.

The maxillary antrolith.

The case of a maxillary antrolith discovered as an incidental finding on a panoramic radiograph is presented. The literature is reviewed, with particular reference to etiology, clinical features, and radiographic findings. The value of facial tomographs taken in two directions pertaining to the present and similar cases is discussed.

Radiology of maxillofacial gunshot injuries.

The relative advantages and disadvantages of conventional facial radiographic techniques, facial tomography, and carotid arteriography for gunshot injury cases are discussed. The conventional series of skull, facial, or cervical spine projections forms a base line upon which the more complex procedures may be added. Five cases illustrate the radiographic principles involved in the determination of gunshot fragment localization, bone fracture, soft-tissue swelling, and maxillary sinus involvement.

Oral radiographic changes in patients with progressive systemic sclerosis (scleroderma).

Intraoral and panoramic radiographs were made of 35 patients with progressive systemic sclerosis. Of those patients, 13 (37%) were found to have abnormally thickened periodontal ligament spaces. Six of the 35 demonstrated mild to significant resorption of the posterior mandibular angle. Three patients, including two showing angle resorption also had some degree of coronoid process destruction. All patients with this disease should receive initial and follow-up panoramic radiographic examinations to determine any osseous changes.
