Tomoko Iizumi, Mariko Yoshino, Hitoshi Kagaya, Kazuhiro Hori, Takahiro Ono
The physiological mechanisms underlying Stage II transport (STII), during which comminuted solid food is transported from the oral cavity into the meso-pharynx for aggregation into a pre-swallow bolus, have yet to be clarified. The purpose of the present study was to investigate relationships between tongue-palate contact during mastication and incidence of STII by synchronized analysis of tongue pressure production on a hard palate and video-endoscopic (VE) images during mastication. Tongue pressure at 5 measuring points with an ultra-thin sensor sheet attached to the hard palate and trans-nasal VE images while masticating corned beef was recorded for 12 healthy subjects...

BACKGROUND: High-intensity eccentric-concentric contractions of the jaw-closing muscles induce muscle soreness, fatigue, and functional impairment of the jaw, resembling the symptoms of myalgia, according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). However, it is claimed that repetition of similar exercises can minimize these detrimental effects. OBJECTIVE: This study aimed to evaluate the response of jaw closing muscles following two series of intense eccentric-concentric exercises of the masticatory muscles in healthy subjects...

This study aimed to deduce evidence-based clinical clues that differentiate temporomandibular disorders (TMD)-mimicking conditions from genuine TMD by text mining using natural language processing (NLP) and recursive partitioning. We compared the medical records of 29 patients diagnosed with TMD-mimicking conditions and 290 patients diagnosed with genuine TMD. Chief complaints and medical histories were preprocessed via NLP to compare the frequency of word usage. In addition, recursive partitioning was used to deduce the optimal size of mouth opening, which could differentiate TMD-mimicking from genuine TMD groups...

It is well accepted that the presence of cytokines belonging to the Th1/Th17/Th22 axis of immuno-inflammatory response in the joint environment, such as IL-1β, IL-17, and IL-22, respectively, are associated with pathogenesis of several synovial joint degenerative disorders. During temporomandibular joint osteoarthritis (TMJ-OA), IL-1β and IL-17 have been implicated in the inflammation and resorption of sub-chondral bone; however, the role of Th22-response in the TMJ-OA pathophysiology has not been established...

BACKGROUND: Swallowing is a muscular activity that occurs both after mastication and spontaneously as a result of saliva accumulation. Spontaneous saliva swallowing occurs about every 2 min. Comprehension of its functional mechanisms is relevant to assess their modification in clinical situations. A standardized surface electromyographical (ssEMG) protocol for the evaluation of this muscle activity is lacking. OBJECTIVES: i)to determine the reproducibility of a ssEMG protocol for the evaluation of the oral phase of saliva swallowing, ii)to evaluate the activity of masseter(MM), anterior temporalis(TA), submental muscles(SM) to draw a reference model of swallowing...

BACKGROUND: The correlation between chewing and gastric function is best reflected when the same food type is used during both tests. We proposed frankfurter sausage as test food for masticatory performance since it can also be used in gastric emptying test. The suitability of frankfurter sausage to determine masticatory performance, however, has never been examined. OBJECTIVE: To examine the correlations between the median particle size of frankfurter sausage and almonds (as standard test food) after different numbers of chewing cycles...

Tooth wear in bruxing patients often results in a need for treatment with composite restorations. In some cases, bruxing patients receive an occlusal splint as a protective means as well. However, the wear between these opposing materials has not been investigated yet. The aim of this in-vitro study was to assess the wear of different splint materials against resin composite materials. A two-body wear test was conducted using the ACTA wear machine. The materials selected for this study were three composites used for direct restorations (Filtek Z250, CLEARFIL AP-X, and Filtek Supreme XT) and four occlusal splints materials, viz...

INTRODUCTION: The effects of masticatory muscles' overloading on jaw-motor control are not yet fully clarified. Therefore, it was tested whether eccentric and concentric exercises of the human masticatory muscles would influence inhibitory jaw-reflex responses. METHODS: 11 participants (6 males, 5 females) performed 6, 5-min bouts of eccentric-concentric contractions. Before, immediately after, 24 hours, 48 hours, and one week afterwards, visual analogue scale (VAS) scores for jaw-muscle fatigue and pain, maximum voluntary bite force (MVBF), and inhibitory jaw reflexes were recorded...
