Abstract:
Agreement between observers classifying TMJ sounds from data given in records of nonpatient adolescents was almost perfect in this interobserver study. Intraobserver and interobserver agreement in classifying all specific TMJ sounds at palpation and auscultation was acceptable to moderate (kappa value = 0.49 to 0.74). The agreement was considerably more reliable when classifying only one specific TMJ sound. Measurements of linear jaw opening showed small interobserver differences (coefficient of variation = 2.4 to 3.8). The significant difference found in calculating the angular mandibular opening may be the result of difficulties in maintaining maximum passive opening.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
