Sleep-related movement disorders are characterized by the specific phenotypes of muscle activities and movements during sleep. However, the state-specific characteristics of muscle bursts and movement during sleep are poorly understood. In this study, jaw-closing and -opening muscle electromyographic (EMG) activities and jaw movements were quantified to characterize phenotypes of motor patterns...

Odontogenic cysts are pathological cavities enclosed by fibrous connective tissue and lined with epithelial that develops from odontogenic tissues in the maxilla mandible's tooth-bearing regions. Trauma or tooth caries is main cause of radicular periapical cysts. Pulp necrosis outcome dental irritating pulp cavity. Once infection has reached root's tip, it causes periodontitis, which may lead t...

The sequential oral functions of mastication and swallowing are well tuned in humans. To prevent hypofunction as a risk factor for systemic frailty by motor training, semi-powered exoskeleton was developed evaluated its loading/assist effects monitoring electromyography signals saliva secretion healthy persons. actuator the driving unit combined mechanical powered mechanics driven alternatively...

Actinomyces-associated lesions in the jaw, such as radicular cyst and osteomyelitis, have been reported by many authors. The lesions are caused by infection from peripheral sites and can be seen to contain Actinomyces druses on pathologic examination. To our knowledge, no previous reports have described Actinomyces-associated calcification in the jaw, although the lesions in the jaw often inclu...

Motor cortex transcranial direct current stimulation (tDCS) has been shown to enhance motor learning in healthy adults as well as various neurological conditions. However, there has been limited data on whether tDCS enhances jaw motor performance during different oral behaviors such as speech, maximum syllable repetition, and chewing. Because the effects of anodal and cathodal stimulation are k...
