BACKGROUND: Temporomandibular joint hypermobility (TMJH) can manifest higher range of motions in mandible. The aim of this study was to investigate and compare the activity of masticatory muscle of TMJs in healthy individuals and patients with mild, moderate and severe TMJH. MATERIAL AND METHODS: In this clinical study, 69 patients (between the ages of 22 to 42) with manifestation of TMJH were included. The patients were divided into three groups based on their maximum mouth opening (MMO): (light) with MMO of 50-55 mm; (moderate) with MMO between 55 to 65 mm; and (severe) with MMO >65 mm...

INTRODUCTION: Proper imaging allows practitioners to evaluate an asymptomatic tempormandibular joint (TMJ) for potential degenerative changes prior to surgical and orthodontic treatment. The recently developed cone-beam computed tomography (CBCT) allows measurement of TMJ bony structures with high accuracy. A study was undertaken to determine the morphology, and its variations, of the mandibular condyle and glenoid fossa among Malay and Chinese Malaysians. METHODS: CBCT was used to assess 200 joints in 100 subjects (mean age, 30...

OBJECTIVE: to assess the prevalence of headaches and painful tempormandibular disorders (TMDs) and examine these via demographic and specific lifestyle parameters, as well as examine the relationship among TMDs, headaches, and depression rates. METHOD AND MATERIALS: a group of 359 medical and dental students completed a detailed questionnaire regarding demographic features and the presence of headaches and facial pain. The survey included a section on lifestyle (nutrition, alcohol and tobacco consumption, physical activity) and a Zung depression assessment...

INTRODUCTION: Our objectives were to demonstrate how standard epidemiologic measurements can assist in evaluating the risk factors for tempormandibular joint and muscle disorders (TMJMD) and to determine whether prevention is feasible. METHODS: We reviewed 2 recent studies that examined third-molar extractions and severe mandibular retrognathia as risk factors for TMJMD. Cumulative incidences were available from these studies. By using these values, standard epidemiologic measurements of risk, including population attributable risk (PAR), attributable risk (AR), population attributable risk percent (PAR%), and attributable risk percent (AR%), were calculated...

OBJECTIVE: To evaluate the clinical efficacy of intra-articular injection with 2% chitosan as a treatment for irreducible anterior disc displacement of the TMJ. METHODS: Total 30 patients with irreducible anterior disc displacement were divided into two groups according to quasi-randomizaion. The patients in test group received intra-articular injection with 1.0 ml of 2% chitosan into upper cavities of the suffered joints, in control group with 12.5 mg of prednisolone...

The expression of tenascin (TN) in the tempormandibular joint (TMJ) disc and synovial membrane was examined in 18 human TMJ samples from patients with internal derangement of the TMJ and ten control specimens by an immunohistological technique using paraffin-embedded tissue and specific anti-human TN monoclonal antibody (RCB-1). The expression of TN was observed in all 28 samples, but it was limited to the walls of blood vessels, the perineurium, and the surface of the TMJ disc. The expression of TN was diffuse in the stroma of mildly hypertrophic synovial membranes and focal in the surface of severely hypertrophic synovial membranes...

A screening examination for the assessment of tempormandibular joint dysfunction was evaluated in a series of 279 patients. Tenderness upon palpation of one or more of the muscles of mastication and/or pain upon retrusion of the mandible was noted in seventy-nine patients (28 per cent). These objective signs of temporomandibular joint dysfunction did not correlate statistically with maximum opening of the mouth, age, taking of analesics or tranquilizers, headache or dizzy spells, crepitus, and the patients dental condition...
