Introduction: The motion and the anatomy of the temporomandibular joint (TMJ) is very complex. Static or pseudo-dynamic MRI of the TMJ does not allow for full analysis of the disc deformation and displacement during the mandibular motion. The purpose of this study was to develop and evaluate a fast dynamic MRI technique for measurement of the TMJ with an arbitrary reconstruction window time poi...

BACKGROUND Purpose of this study was to modify the stethoscope which can auscultate the temporomandibular joint (TMJ) sounds more precisely than conventional stethoscope, and fabrication of stethoscope compatible software which analyses the auscultated sound and gives documentary evidence of that analysis in the form of graph. MATERIALS & METHODS The conventional stethoscope was modified by a...

INTRODUCTION This study was to investigate whether there was statistical difference between the bilateral temporomandibular joint (TMJ) in patients with unilateral TMJ pain or joint sounds, using cone beam computed tomography (CBCT). METHODS TMJ CBCT images of 123 cases were used to preliminarily determine the indicators suitable for the measuring method. TMJ CBCT image reconstruction was per...

The purpose of this study was to investigate the expression of PG mRNA in human temporomandibular joint (TMJ ) disks from patients with temporomandibular disorders (TMD). Total RNA was isolated from the TMJ disks. All patients had undergone diskectomy under general anethesia. RT-PCR was performed using primers for the proteoglycans, aggrecan and decorin. On electrophoresis of a lysate of human ...

Synovial chondromatosis (SC) of the temporomandibular joint (TMJ) is a rare benign condition characterized by the formation of metaplastic cartilage in the synovium resulting in numerous attached and unattached osteocartilagenous (calcified) loose bodies within the joint. The purpose of this article is to present a case of SC of the TMJ and to discuss current diagnostic approaches, treatment op...

Synovial chondromatosis (SC) is a rare, benign cartilaginous metaplasia that affects the joints, usually only one joint. Chondromatosis is a hard to diagnose disease because of its somewhat vague symptoms, especially those in the temporomandibular joint (TMJ), which does not fit those from the most prevalent disease sites (knee, elbow and shoulder). There is only one case of TMJ chondromatosis ...

PURPOSE This study investigated the prevalence of Temporomandibular Disorders (TMD) in the elderly and its association with palpation of the temporomandibular joint (TMJ), masticatory and cervical muscles as well as the presence of headache and joint noises. METHODS The sample consisted of 200 elderly of both genders (mean age: 69.2±5.7 years). The clinical evaluation of TMD signs and symptom...

Aims: To determine the association between more advanced stages of temporomandibular joint intra-articular disorders (“TMJ intraarticular status”), representing a transition from normal joint structure to TMJ disc displacement with and without reduction (DDwR and DDwoR) to degenerative joint disease (DJD), and patient-reported outcomes of jaw pain, function, and disability (“TMD impact.”) Metho...

Alloplastic total replacement of the temporomandibular joint (TMJ) was developed in recent decades. In some conditions, previous studies suggested the rationale behind alloplastic TMJ replacement rather than reconstruction with autogenous grafts. Currently, three prosthetic products are available and approved by the US Food and Drug Administration. Among these products, customized prostheses ar...

The presence of body posture changes among patients with temporomandibular disorders (TMD) has been a controversial topic in dentistry. Based on that, the aim of this study was to assess postural features of pain-free subjects with internal derangement of the temporomandibular joint (TMJ), viz. disc displacement, when compared to subjects with normal disc position. A total of 21 subjects with u...
