Effects of polyarticular and pauciarticular onset juvenile rheumatoid arthritis on facial and mandibular growth.

Objective: To characterize the functional and morphologic effects of polyarticular and pauciarticular onset juvenile rheumatoid arthritis (JRA) on the temporomandibular joint (TMJ).

Methods: Medical and dental histories, intraoral, lateral cephalometric, and panoramic radiographs, facial photographs, and dental study models were obtained for each of 30 patients with JRA (17 pauciarticular and 13 polyarticular onset). Measures of TMJ dysfunction were gathered during the clinical examination, and an index of condylar morphology was inferred from the panoramic radiographs.

Effects of systemic onset juvenile rheumatoid arthritis on facial morphology and temporomandibular joint form and function.

Objective: Twenty-four patients with systemic onset juvenile rheumatoid arthritis (JRA) were evaluated to determine its effects on facial morphology and temporomandibular joint (TMJ) form and function.

Methods: Patients were evaluated with medical and dental histories, facial photographs, intraoral examination, TMJ examination, lateral tomograms or panoramic radiographs, cephalograms, and impressions for study models. The craniomandibular index (CMI) was used to quantitate mandibular movement, tenderness, and TMJ noise.

A comparison of surgery and orthodontics in "borderline" adults with Class II, division 1 malocclusions.

From a pool of 108 former patients, discriminant analysis was used to identify a homogeneous borderline prognostic subgroup of 27 adult orthodontic and 26 adult surgical Class II patients who, before treatment, were similar with respect to the characteristics on which the orthodontic/surgical decision appears to have been based. The fact that some had been treated orthodontically, whereas others had been treated surgically, was taken as empirical evidence that the patients in this stratum were equally susceptible to the two treatments and that the actual choice was largely a function of whose office they happened to contact. The former orthodontic patients were recalled an average of 7.

Condylar osteochondroma manifesting as Class III skeletal dysplasia: diagnosis and surgical approach.

This is a case report of a 21-year-old man who had a gradually progressive Class III malocclusion and crepitation of the right temporomandibular joint. Routine TMJ tomograms revealed a radiopaque-radiolucent lesion of the right mandibular condyle with a compensatory anteroinferior displacement of the left mandibular condyle. Nuclear bone scans confirmed increased asymmetric technetium 99 tracer uptake in the region of the right temporomandibular joint.
