  1. Effect of food consistency on the degree of mineralization in the rat mandible.

    Annals of Biomedical Engineering 35(9):1617 (2007) PMID 17522978

    A switch to a soft diet, associated with reduced forces applied to the mandible during mastication, may result in an alteration of the degree of mineralization in the mandible. This alteration may be regionally different. The aim of this study was to analyze this alteration by examination of the deg...
  2. Plasticity of mandibular biomineralization in myostatin-deficient mice.

    Journal of Morphology 268(3):275 (2007) PMID 17299778

    Compared with the normal or wild-type condition, knockout mice lacking myostatin (Mstn), a negative regulator of skeletal muscle growth, develop significant increases in relative masticatory muscle mass as well as the ability to generate higher maximal muscle forces. Wild-type and my...
  3. [Influence of bruxism during sleep on stomatognathic system].

    Kokubyo Gakkai zasshi. The Journal of the Stoma... 66(1):76 (1999) PMID 10332150

    Nocturnal tooth contact such as bruxism has been considered to be one of the major factors of temporo-mandibular disorders (TMD). However, little information has been reported regarding mandibular movements during bruxing, because of the limitation of the measuring method. The purpose of this study...
  4. An anomalous digastric muscle with three accessory bellies and one fibrous band.

    Surgical and Radiologic Anatomy 20(6):453 (1998) PMID 9932332

    We encountered an anomalous digastric muscle with three accessory bellies and one fibrous band in one embedded cadaver. All of these structures were attached to the mylohyoid raphe. This anomaly should be considered during surgical procedures involving this region....
  5. Controllability of temporomandibular joint loading by coordinative activities of masticatory muscles: a two-dimensional static analysis.

    Frontiers of Medical & Biological Engineering 8(2):123 (1997) PMID 9257133

    We analyzed the relationship between TMJ loading and the activities of the masticatory muscles, by employing a static two-dimensional jaw model. This comprises two rigid bodies, the upper and lower jaws, including three dominant muscles, i.e. the masseter, the anterior portion of the temporalis and...
  6. The efficacy of oral myofunctional and coarticulation therapy.

    The International journal of orofacial myology ... 23:3 (1997) PMID 9487825

  7. Morphology and analysis of the development of the human temporomandibular joint and masticatory muscle.

    Acta Anatomica 149(1):55 (1994) PMID 8184659

    The calcification levels of the mandible and the temporal bone of human fetuses, which ranged from 12 to 32 weeks of gestation, were systematically investigated with a soft X-ray analyzer linked to an image analyzer. The profile of the condylar process (head) revealed high levels of calcification, i...
  8. [Electromyographic response to progressive activation of functional appliances]

    Mondo Ortodontico 16(2):183 (1991) PMID 2072955

    The Authors, according to the literature, carried out an electromyographic study on young Class II patients. Muscolar activity was studied during rest and with Frankel's functional regulator in different conditions of activation. Analysis of obtained results supports the author's idea of an individu...
  9. The shape of the mandible in the domestic sheep: a biomechanical analysis using EMG as an estimator of muscle force.

    Acta morphologica Neerlando-Scandinavica 27(1-2):63 (1989) PMID 2816528

    We investigated the patterns of activity of the masticatory musculature by multichannel electromyography, expressing the activity of any particular muscle during a given interval as a percentage of the highest activity recorded for the muscle in question. In combination with data on the physiologica...
  10. Expression of fiber type specific proteins during ontogeny of canine temporalis muscle.

    Muscle & Nerve 11(2):124 (1988) PMID 3343987

    We conclude that (1) the temporalis muscle develops from embryonic fibers that initially contain a myosin indistinguishable from embryonic limb muscle fibers, suggesting they have a common precursor, and (2) the myosin light chains and heavy chain unique to the temporalis muscle are initially expres...
