Structural lesions of the TMJ in relation to Mycoplasma pneumonia infections.

Aims: The presence of different types of bacteria in the temporomandibular joint (TMJ) is considered an etiological factor in TMJ pathologies. Mycoplasma pneumonia (MP), for instance, can be present in different joint pathologies. The aim of the present study is to correlate pathognomonic imaging of the TMJ in nuclear magnetic resonance with laboratory tests for MP.

Application of a cephalometric method to the temporomandibular joint in patients with or without alteration in the orientation of the mandibular condyle axis.

In a prior study, the spatial relationship of the mandibular condyle was studied through a cephalogram based on laminographies of the temporomandibular joint (TMJ). The present method was developed with the aim of analyzing TMJ morphology and the spatial relationship of the mandibular head within the mandibular fossa, considering references far from these structures, as they may suffer shape alterations. This study was conducted in view of the importance of the study of morphology and the hard structures relationship, which constitutes the temporomandibular joint.

Temporomandibular joint method to study the morphology and relationship of the hard structures.

Different methods have been suggested to study mandibular condylar position. These methods are based on the study of the joint space between the condylar head surface and the glenoid fossa. In all of these methods, joint structures were always regarded as healthy and in ideal shape, a fact that we know to be not always true.
