To determine the prevalence of temporomandibular joint internal derangement in patients with signs and symptoms of craniomandibular disorders, bilateral imaging was performed in a consecutive series of 115 patients with signs and symptoms of craniomandibular disorders. Ninety patients (78%) had different stages of unilateral or bilateral internal(More)
To determine if the quality of spin-echo magnetic resonance (MR) images of the temporomandibular joint (TMJ) could be improved by reducing section thickness, coronal and sagittal 3.0- and 1.5-mm MR images of the same joints were evaluated. Depiction of the disk, trabecular pattern, and cortex of the condyle was better on coronal 1.5-mm images than on 3.0-mm(More)
In an attempt to better understand the cause of different types of temporomandibular joint (TMJ) sounds, we recorded joint sounds from 27 fresh autopsy specimens, displayed the time frequency distribution of the sound as a three-dimensional graph, and correlated the sound character to morphologic observations at subsequent dissection. Eleven joints elicited(More)
The horizontal condylar angle was measured in axial magnetic resonance images of normal and abnormal temporomandibular joints (TMJs). The average condylar angle in the normal joints was 21.2 degrees. In joints with disk displacement with reduction it was 29.7 degrees; joints with disk displacement without reduction, 33.5 degrees; and in joints with(More)
An equation for predicting endogenous creatinine clearance (CrCl) in adults and children (with both stable and unstable renal function) from serum creatinine concentration is presented. The predictions are compared with four other available estimating methods, bases on values in 110 subjects with renal impairment of widely differing degrees. In patients(More)
This study investigated the accuracy of clinical examination in determining the status of the temporomandibular joint with respect to internal derangement and arthrosis. A series of 110 patients was given standard clinical examinations followed by bilateral imaging with arthrography and/or magnetic resonance imaging. There was agreement between the clinical(More)
The model of experimental pyocyanic renal infection in rats based on direct inoculation of bacteria to the renal parenchyma is described. The authors describe in detail the procedure and evaluation of the results with respect to microbiology, histology and reproducibility. The method produced a focal supurrative inflammation with a significant(More)
Abnormalities within the temporomandibular joints often produce audible sounds. Electronic recording of joint sounds has been used as a method of staging internal derangement. This study had three objectives: first, to determine whether the characterization of temporomandibular sounds can provide a sensitive and accurate measure for the presence or absence(More)
PURPOSE The purpose of this study was to evaluate the contribution of unilateral disk displacement to growth changes in the young New Zealand White rabbit. METHODS Ten female rabbits aged 10 weeks were included in this study. The five experimental rabbits had unilateral anterior disk displacement surgery. The five controls had no surgery. The rabbits were(More)
