This study evaluated the occurrence of degenerative temporomandibular joint (TMJ) changes in adolescents and young adults with recent on-set disc displacement without reduction (DDw/oR) using high-resolution cone beam computed tomography (CBCT). The associations between types of osteoarthrosis (OA) changes and clinical factors including disease duration were also examined. CBCT and clinical data of 300 patients (84.70% females, mean age 20.93 ± 4.77 years) diagnosed with unilateral DDw/oR (≤12 months) based on RDC/TMD were acquired...

Background Temporomandibular disorders (TMD) is an umbrella term for pain and dysfunction involving the masticatory muscles and the temporomandibular joints (TMJs). TMD is the most common orofacial pain condition. Its prominent features include regional pain in the face and preauricular area, limitations in jaw movement, and noise from the TMJs during jaw movements. TMD affects up to 15% of adults and 7% of adolescents. Chronic pain is the overwhelming reason that patients with TMD seek treatment. TMD can associate with impaired general health, depression, and other psychological disabilities, and may affect the quality of life of the patient...

OBJECTIVE: Cartilage fatigue, due to mechanical work, may account for the early development of degenerative joint disease (DJD) in the temporomandibular joint (TMJ), and why women are three times more likely to be afflicted. This study tested for gender differences in mechanical energy densities in women and men with healthy TMJs. DESIGN: Eighteen women and eighteen men gave informed consent. Research diagnostic criteria including imaging were used to ensure that subjects' TMJs were normal, without disc displacement or signs of DJD...

Temporomandibular joint disorders (TMJDs) are a complex group of disorders that comprise dysfunctions of the temporomandibular joint (TMJ). In this study, we analyzed the objective and subjective findings of the TMJD patients by using Helkimo anamnesis (Ai) and clinical dysfunction (Di) indices, and tried to document a relation between these findings and magnetic resonance imaging (MRI) results.Ninety-eight patients who were admitted to our clinic were included in the study. The clinical evaluation was performed by using Ai, an 8-question-survey based on the objective symptoms of patients; Di, concluded as the score of 5 objective measurements of physical examination...

BACKGROUND: 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., disk displacement, when compared to subjects with normal disk position. MATERIALS AND METHODS: 21 subjects with unilateral, pain-free TMJ disk displacement (DD) and 21 subjects without any TMD signs of symptoms were assessed for body posture changes by means of posturographic evaluation of several body segments and postural balance reactions through the center of mass during jaw movements using a balance platform...

Internal derangement (ID) in the temporomandibular joint (TMJ) comprises a group of clinical problems with relatively high prevalence. However, the temporal changes in gene expression of condylar cartilage during continuous ID remain unclear. The aim of the current study is to investigate by microarray analysis, the differentially-expressed gene pattern in condylar cartilage of rabbits with ID from one to eight weeks of ID progression. Histological results (hematoxylin and eosin staining) indicated that abnormal collagen fiber arrangements, fragmentation of fibrils, and inflammatory cell-infiltration were detected from one to four weeks in joint disc specimens, while newly formed vessels, mucoid degeneration, meniscal tears, and the presence of osteoclasts and osteoblasts were observed at later time points...

The goal of rehabilitation after temporomandibular joint (TMJ) surgery is to achieve a normal range of motion. The aim of this study was to compare the impact of a comprehensive and early supervised rehabilitation programme with home-based exercise after TMJ condylar discopexy. Patients diagnosed with disc displacement without reduction were randomized to the study and control groups. After baseline assessments, the same surgical condylar discopexy procedure was applied to both groups. Following surgery, the study group patients underwent a supervised exercise programme conducted by a physiotherapist in the outpatient clinic...

The longitudinal course of temporomandibular joint (TMJ) disc displacement (DD) and degenerative joint disease (DJD) has never been conclusively described with magnetic resonance imaging and computed tomography, respectively. This 8-y observational study's objective was to assess the longitudinal stability of DD and DJD among 401 subjects. The Validation Project provided baseline measures; follow-up was performed in the TMJ Impact Project. With magnetic resonance imaging, 2 radiologists rendered a consensus diagnosis of normal/indeterminate, DD with reduction, or DD without reduction...

OBJECTIVE: To evaluate the effect of magnetic resonance imaging-cone beam computed tomography (MRI-CBCT) image registration on inter- and intraexaminer consistency when evaluating temporomandibular joint (TMJ) internal derangement compared to MRI alone. METHODS: MRI and CBCT images of 25 patients (50 TMJs) were obtained and coregistered using mutual-information rigid image registration via Mirada XD software. Two experienced radiologists independently and blindly evaluated two types of images (MRI alone and MRI-CBCT registered images) at two different times (T1 and T2) for TMJ internal derangement, based on sagittal and coronal articular disc position in relation to the head of the condyle and the posterior slope of the articular eminence...

We evaluated the effects of chitosan membrane, a highly absorbable and viscous material, in the prevention of intra-articular adhesions after anchoring of the disc in the temporomandibular joints (TMJ) of six adult goats (12 joints). To simulate anterior displacement of the disc and TMJ trauma, we cut off the retrodiscal attachment and damaged the surface of the condylar bone, then randomly divided the goats into two groups: the control group (n=2) and the experimental group (n=4). In the experimental group we covered the condylar surfaces on both sides of the animals with chitosan membranes...

Two different surgical methods for the treatment of unilateral traumatic temporomandibular joint (TMJ) ankylosis with a medially displaced residual condyle are described. Eighteen patients with unilateral traumatic TMJ ankylosis and a medially displaced residual condyle, treated between 2008 and 2013, were included in this study. Group A patients (n=10) were treated with an autogenous coronoid process graft (ACPG) for reconstruction of the mandibular condyle, while group B patients (n=8) were treated by lateral arthroplasty (LAP); a temporalis myofascial flap (TMF) was used as interpositional material in both groups...

Temporomandibular joint (TMJ) pain can be difficult to diagnose and treat. We describe a patient with left jaw pain after right hemimandibulectomy. The patient was initially managed conservatively, which failed to reduce pain. He was then administered inferior alveolar nerve block and TMJ injection with steroid and local anesthetic. These injections provided temporary pain relief that lasted approximately 1 month and the pain recurred. Computed tomography scan showed lateral displacement of left mandibular condyle...
