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
… shown a genetic association with OSA. Given that masseter muscle influences skeletal malocclusion and is active during OSA, we investigated whether the expression of OSA-associated genes is altered in a Class II open bite OSA subject. Methods: Eleven mandibular advancement surgery patients were …

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 …

Association of Masseter Muscle PITX2, ENPP1 and ESR1 Expression, Muscle Fiber Type, Temporomandibular Joint Disorders and Subclassifications of Craniofacial Asymmetry
… type differences compared between right and left masseter muscles. We developed an asymmetry classification that diagnosed four types of asymmetry with distinctive growth patterns: Group 1 – menton deviation without ramal difference (“mandibular body asymmetry”); Group 2 –menton deviation with …

Avaliação Eletromiográfica nos músculos masseter e temporal anterior após o uso de placa de Hawley modificada, em pacientes com DTM
… a atividade eletromiográfica dos músculos masseter e temporal anterior na condição de repouso e em contração isométrica máxima. Pretende-se relacionar as mudanças ocorridas na atividade eletromiográfica desses músculos com a evolução dos sinais e sintomas relatados nas diferentes aplicações …

EXPRESSION OF HISTONE DEACETYLASE 4 AND HISTONE ACETYLTRANSFERASE 4 IN HUMAN MASSETER MUSCLE: RELATIONS TO FIBER-TYPE COMPOSITION IN PATIENTS WITH MALOCCLUSIONS
… genes and fiber-type percent occupancy (%Occ) in masseter muscle of patients undergoing orthognathic surgery to correct severe dentofacial malocclusions. The diagnostic categories of malocclusion in sagittal and vertical dimensions were: 1) Deep bite-Class II (D2); 2) Deep bite-Class III (D3); 3) …

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) …

ACTN3 R577X GENOTYPES ASSOCIATE WITH CLASS II AND DEEP BITE MALOCCLUSIONS
… ACTN3 expression and genetic variation in masseter muscle of orthognathic surgery patients to determine genotype associations with malocclusion. To determine the associations between genotypes and malocclusions, clinical information, masseter muscle biopsies, and saliva samples were …

The Response of Condylar Cartilage Stimulated by a Small Defect in the Rat Mandible
… suggested that the decreased activity of the masseter, resulting from dissecting a part of the masseter, may play an important role in changing the size or the shape of the rat mandible. In the experimental study, the masseter was not dissected and the results indicated that a hole drilled at …

Jaw mechanics and muscle behavior in adolescents with different craniofacial morphologies
… determined between-group differences. Surface masseter and anterior temporalis electromyography were recorded, unilaterally over two days and nights and bilaterally at two laboratory sessions when subjects did biting tasks to calibrate field recordings. Muscle duty factors were calculated for …

Immediate Effect of Complete Denture Occlusal Errors on Masticatory Muscle EMG Activity in Denture Wearers: A Pilot Study
… and the surface EMG of the right and the left masseter and the temporalis muscles were recorded. Bilateral interferences were removed and the subjects were divided into two groups. Group A received unilateral right interference and group B received unilateral left interference. Surface EMG 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, …

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 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 …

Use of Motion Artifact for the Detection of Respiratory Effort in Polysomnography
… artifact was found to perform best in the masseter. This work shows that movement artifact recovered from the EMG and ECG may be a reliable alternative for the detection of respiratory effort.
