Muscle Spindle Afferent Input to Motoneurons in Human Masseter

open access: yes, 1999
The H-reflex response in large and small single motor units in human deep anterior masseter was studied to investigate the distribution of muscle spindle afferents onto masseter motoneurons.

Electromyography Frequency Spectrum Is a Better Indicator of Sleep Bruxism Severity Related to Temporomandibular Disorder Pain Than Conventional Masticatory Muscle Activation and Bruxism Time Indices—A Pilot Study

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep bruxism (SB) has been reportedly associated with temporomandibular disorder (TMD); however, solid evidence is lacking. Previous studies have primarily used traditional metrics, such as the masticatory muscle activity (MMA) index and bruxism time index (BTI) to investigate the link between SB and TMD.

Nocturnal Masseter Muscle Activity and Urinary Catecholamine Levels in Bruxers

open access: yes, 1980
Nocturnal electromyographic recordings of masseter muscle activity were performed on 20 bruxist and ten control subjects. Each subject collected two 24-hour urine samples. An analysis of urinary catecholamine content was performed.

New Insights Into Diffuse Sclerosing Osteomyelitis: Is There a Role of ANA and Vitamin B6?

open access: yesOral Diseases, EarlyView.
ABSTRACT Object Diffuse sclerosing osteomyelitis is a poorly understood chronic disease, which appears predominantly in the mandible. Female patients are more often affected than men. DSO is an ultra‐rare disease and incidence is unknown; diagnosis can be very challenging; pathogenesis is poorly understood.

Early development of the mammalian superficial masseter muscle in cynodonts

open access: yes, 2004
The masseter muscle is a hallmark of the jaw-closing mechanism of modern mammals, acting in concert with other mandibular adductor muscles to fine-tune oral food processing.

Oral Manifestations of Non Vascular Ehlers‐Danlos Syndrome Cross‐Sectional Study

open access: yesOral Diseases, EarlyView.
ABSTRACT Background Ehlers–Danlos syndromes are rare hereditary connective tissue disorders; however, their oral manifestations remain poorly characterized in molecularly confirmed individuals. The aim of this study was to describe the oral phenotype of patients with non‐vascular Ehlers‐Danlos syndromes compared to healthy controls.

Strain analysis of masseter muscle by ultrasound

open access: yes, 2015
The masseter muscle represents an area of important functional interest. The present study aims to verify the feasibility of ultrasound imaging for quantifying the muscular deformation pattern in the masseter.

Use of liquid platelet‐rich fibrin (liquid PRF) in temporomandibular joint disorders: A narrative review with clinical recommendations

open access: yesPeriodontology 2000, EarlyView.
Abstract Aim This narrative review aimed to gather evidence from comparative and non‐comparative clinical studies to assess: (1) whether the administration of liquid platelet‐rich fibrin (liquid PRF) provides any clinical benefits for managing temporomandibular disorders (TMD), and if so, based on comparative clinical studies, (2) whether it offers ...

Glutamate-induced sensitization of rat masseter muscle fibers

open access: yes, 2002
Item does not contain fulltextIn rats, intradermal or intraarticular injection of glutamate or selective excitatory amino acid receptor agonists acting at peripheral excitatory amino acid receptors can decrease the intensity of mechanical stimulation ...

Technical note on an ovine model to study biomedical implants intended for maxillofacial reconstruction

open access: yesVeterinary Surgery, EarlyView.
Abstract Objective To describe a repeated‐measures model permitting evaluation of up to four implants intended for maxillofacial applications in sheep. Animals Two‐year‐old Merino wethers (n = 5). Methods A retromandibular subparotid approach was developed through anatomical study of atlases, predissected models and cadaveric experiments.
