Disease relevance of Masticatory Muscles

  • The findings of this study suggest that the soft splint is an effective short-term treatment for reducing the signs and symptoms of masticatory muscle pain in patients, and the soft splint does not cause occlusal changes [1].
  • Both patients had parafunctional habits (bruxism), hypertrophic masticatory muscles, and wear of occlusal surfaces [2].
  • AIM: To highlight the effectiveness of orthodontic treatment and bilateral equalization of the vertical occlusal dimension, along with the correction of asymmetric cervical and masticatory muscle activities in patients with Class III malocclusion with lateral deviation of the mandible and severely asymmetric condyle and ramus [3].
  • Materials and Methods: In an randomized blinded placebo-controlled study, 90 patients (60 verum and 30 placebo) with chronic facial pain were treated with botulinum toxin type A (Botox; Allergan, Ettlingen, Germany) injections into masticatory muscles [4].
  • There were 84 patients with clicking, 45 with headaches, 13 with neckaches, 39 with tenderness in the TMJ bilaterally and masticatory muscles and 12 with uncomfortable occlusal relationships [5].

High impact information on Masticatory Muscles

  • It is conceivable that activation of peripheral NMDA receptors may contribute to masticatory muscle pain and that peripherally acting NMDA receptor antagonists could prove to be effective analgesics for this type of pain [7].
  • The extent of proprioceptive deficiencies differed among different masticatory muscles, particularly in NT3 null mice [8].
  • Complements of TMN neurons and masticatory muscle spindles were decreased by 62% in NT3 null mutants, 33% in BDNF null mutants, and 10% in NT4 null mutant mice at birth [8].
  • Occlusal alterations may result in changes in the functional performance of masticatory muscles [9].
  • In each treatment group, masticatory muscle injury was evaluated by contractile tension, plasma creatine kinase, and muscle glycogen [10].
