Combined effects of prozac and hypothalmic mediated response on masseter muscle activity in the cat
… with a bipolar electrode attached to the masseter muscle to establish baseline before the infusion of the drug. Mean frequency values of early and late stimulation were calculated using the continuous wavelet transform. The effects of early stimulation of the medial hypothalamus upon …

Increased Inflammatory Gene Expression in Masseter Muscle of an Orthognathic Surgery Subject with Obstructive Sleep Apnea
… diabetes, and in some cases, retrognathia and muscle dysfunction. The latter two conditions may prompt orthognathic correction. Past investigations have shown a genetic association with OSA. Given that masseter muscle influences skeletal malocclusion and is active during OSA, we investigated …

Association of Masseter Muscle PITX2, ENPP1 and ESR1 Expression, Muscle Fiber Type, Temporomandibular Joint Disorders and Subclassifications of Craniofacial Asymmetry
… associations with functional properties in muscle and bone. The objectives of this study are to investigate how PITX2, ENPP1 and ESR1 gene expression associates with four subclassifications of craniofacial asymmetry, temporomandibular disorders and fiber type differences compared between …

EXPRESSION OF HISTONE DEACETYLASE 4 AND HISTONE ACETYLTRANSFERASE 4 IN HUMAN MASSETER MUSCLE: RELATIONS TO FIBER-TYPE COMPOSITION IN PATIENTS WITH MALOCCLUSIONS
… However, compared with bone, the effect of muscles of the craniofacial complex in the development of dentofacial deformities has received little attention. Recently, cellular and molecular studies of the musculoskeletal interactions have been used to investigate the etiology of dentofacial …

ACTN3 R577X GENOTYPES ASSOCIATE WITH CLASS II AND DEEP BITE MALOCCLUSIONS
… influence contractile properties of skeletal muscle. ACTN2 is expressed in slow type I and fast type II fibers whereas ACTN3 is expressed only in fast fibers. ACTN3 homozygosity for the 577X stop codon (i.e. changing 577RR to 577XX - the R577X polymorphism) results in the absence of …

The Use of a Habit Reversal Treatment for chronic Facial Pain in a Minimal Therapist Contact Format
… hypothesis comes from research demonstrating masseter muscle hyperactivity in response to experimental stressors, such as painful or frustrating stimuli. Many believe the link between stress and increased masseter muscle pain is parafunctional oral habits, including teeth clenching, grinding, …

TEMPOROMANDIBULAR JOINT DISORDERS AND NASAL SEPTUM DEVIATION IN DENTOFACIAL DEFORMITY PATIENTS
… expression evaluation from patient saliva and masseter muscle samples that were obtained at the time of corrective orthognathic surgery. Methods: Pre-surgical posterio-anterior (PA) cephalograms, submentovertex (SMV) and panoramic (PAN) radiographs from 92 pre-surgical dentofacial deformity …

Accelerating development of treatments for trigeminal neuralgia using intranasal delivery and a novel behavioral screening device for rats.
… (teeth, temporomandibular joint (TMJ), and masseter muscle) accumulated up to 20-fold higher tissue concentrations of lidocaine than the brain and blood as measured by ELISA. Intranasally administered infrared dye reached the trigeminal nerve and brain within 10 minutes. Intranasal …

Biomechanical Modeling of the Masticatory Region
… of the sub compartments of the lateral pterygoid muscle, which we used to derive a theory that explains previously published EMG patterns during a contralateral movement of the mandible. Lastly, we investigated possible ways to port the ArtiSynth jaw model to OpenSim, which would increase its …

The Measurement of Maximal Bite Force in Human Beings
… of MVBF, electrical stimulation of the masseter muscle, and EMG recording from two pairs of jaw closing muscles. Results: The highest MVBF values were recorded on the pressure transducer, mean (± S.D.) 464 N ± 224 N; followed by the strain-gauge transducer with EVA sheets, 243 ± 80 N; …

Mechanical Evaluation of Mandibular Defects Restored with rhBMP-2: A Finite Element Model
… bone in response to a 150 N force of the masseter muscle. Results: There was no statistical difference between the mechanical properties among treatment groups. However, both treatment groups showed a statistically significant difference in stress distribution, displacement in the x-axis, …

Estrogen Signaling in Trigeminal Nociception
… of Complete Freund's adjuvant (CFA) into the masseter muscle, to determine whether ERK activation may play a role in hormone-related trigeminal pain disorders. We measured withdrawal responses to stimulation of the masseter (V3, primary allodynia) and whisker pad (V2, secondary allodynia) …

Mechanical Monitoring of Inhibitory Jaw Reflexes in Health and Simulated Dysfunction
… teeth and electromyograms (EMGs) from the masseter muscles. Transcutaneous electrical stimuli were applied to the hairy skin of upper lip while the subjects maintained a biting force of around 50N with the aid of visual feedback. In the first series of experiments, a range of electrical …

Statische und kinematische topographische Darstellungen der Aktivität des Musculus masseter durch klassische Analysemethoden und Wavelet-Transformation
… und histochemisch hoch differenzierten M. masseter weisen seine vielfältigen Funktionen. Polymyographische monopolare Aufzeichnungen des rechten M. masseter wurden unter isometrischen und dynamischen Bedingungen an 14 orthognathen Probanden durchgeführt. Statische Unterkieferstellungen …
