Therapeutic exercise is a new concept of treatment for patients with clicking due to anterior disk displacement with reduction (ADDWR). In order to investigate the efficacy of the exercise, we designed a randomized controlled clinical trial to compare with no-treatment controls. The subjects were patients who complained of painless unilateral reciprocal clicking and were diagnosed as having ADDWR by Magnetic Resonance Imaging (MRI). Forty-two patients were randomly assigned. Three months after the randomization, the success ...

 This study clinically documents the presence of disk-attachment pain (DAP) related to the severity of bruxism and to the prevalence of internal joint disorders in patients and controls. The sample consisted of 394 temporomandibular disorder (TMD) and bruxing behavior patients and 104 nonbruxer control subjects. The TMD group was subdivided in a group of 109 disk-attachment pain patients and 285 bruxing behavior-nonDAP groups. The second reference group was a sample of 104 nonbruxing behavior subjects ...

This study was aimed at evaluating the effects of a novel physiotherapy machine called MAGMA (AntiGravitary Modification of the Myotensions of Asset) on postural and masticatory muscles of subjects with myogenic cranio-cervical-mandibular dysfunction (CMD), by using surface electromyography (sEMG). Fifteen subjects, nine males and six females (mean age 27.6 years), with CMD were included in the study. The bilaterally monitored muscles were: masseter, anterior and posterior temporalis, digastric, posterior cervical, sternocleidomastoid, and upper and ...

The purpose of this study was to evaluate the age-related differences in the incidence, length and topographic location of ossification in the stylohyoid chain. Panoramic radiographs of 420 patients (795 reviewed stylohyoid-chains), subdivided into 4 age groups (20 years and under, 21 to 40 years, 41 to 60 years, older than 60 years) were reviewed and examined for the incidence, length and topographic location of stylohyoidal ossification. 245 (30.8%) out of 795 reviewed stylohyoidal ...

The purpose of this study was to quantify the urinary bone resorption markers, pyridinoline (Pyr) and deoxypyridinoline (Dpyr), excreted from experimentally-induced osteoarthritis (OA) in the temporomandibular joint (TMJ) of rats. Osteoarthritic lesions were induced by intra-articular injection of collagenase into the right TMJs of 16-week-old male rats. The whole day’s urine was collected from each animal one day before the injection and 5, 7, 11 and 14 days after the injection. Urine samples were ...

Clear findings relative to where in the brain the starting point of voluntary swallowing is controlled were obtained in the present magnetoencephalographic study. Namely, the cerebral activity was observed in the cingulate gyrus and supplementary motor area for about 80 ms between 1,000 and 1,500 ms before swallowing in all test subjects. Thus, it is clear that this type of central control mechanism also plays an important role in complicated swallowing movements.

This study describes the coordinated treatment of temporomandibular disorders (TMD) and cervical spine disorders in patients diagnosed with Meniere’s disease. The aim was to follow up treatment outcomes for three years with regular follow-up examinations every six months. Of the 31 patients with Meniere’s disease who participated in a controlled comparative study on the signs and symptoms of TMD, 24 participated in a subsequent controlled comparative study on the signs and symptoms of ...

A 31-year-old man who had been diagnosed with obstructive sleep apnea syndrome (OSAS) due to retrognathia was referred to our hospital. Before treatment, the angle of the sella-nasion-point B (SNB) was 67 degrees. The lowest oxygen saturation (SpO2) during sleep was 77%, the longest-running episode of sleep apnea was 128 seconds, and his apnea index (Al) was 29.9. He underwent bilateral horizontal mandibular distraction osteogenesis using intraoral distraction devices. After mandibular distraction, SNB increased ...
