“…results it seemed to play positive effects on muscle tissue as important injuries were not observed at group III. Furthermore, although the findings of the present study were restricted to a specific set of parameters and that optimal treatment parameters (e.g., wavelength, dosage, number of treatment sessions) have not been, so far, agreed upon (Emshorff et al; Venancio et al), previous studies have been beneficial results using Infrared wavelengths (Çetiner et al;Fikáková et al;Kato et al, 2006;Kogawa et al, 2005;Leal Júnior et al, 2008).…”

SUMMARY:The aim of this study was to analyze the influence of low-intensity laser therapy and muscle relaxant in the characteristic ultra structural masseter muscle occlusal wear. Animals and Methods: 40 male Wistar rats were randomly divided into four groups: the control group (GI), occlusal wear (G-II), laser occlusal wear (G-III), and the muscle relaxant occlusal wear (G-IV). Under general anesthesia given intraperitoneally, animals in groups II, III and IV had unilateral amputation of upper and lower molar cusps to simulate an occlusal wear situation. The masseter muscle G-III received laser therapy (830nm, 4J/cm2, 40mW, f ~ 2mm) and the procedure was subsequently repeated every other day for 14/30 days. G-IV animals were treated with daily injection of dantrolene ® (2.5 mg / kg in 0.5 ml of H 2 O). From 24 hours after the elimination peak. The animals were euthanized with an overdose of anesthesia on days 14 and 30 after the removal of the cusps and the ipsilateral masseter muscle was excised and divided in two, one half was routinely processed for light microscopy and other for electron microscopy. There was no statistical difference between each experimental group and the control and between periods in each experimental group. However, the muscle fibers in the G-II showed the most pronounced changes. There is no causal relationship between muscles fibers injuries and occlusion and, despite signs of muscular tissue injury were more evident in the occlusal wear group. Results indicates a moderate action of laser therapy and muscle relaxants in skeletal muscle.

“…But in our study, we found a significant improvement in neck muscle pain along with TMJ muscles. Santos et al, 16 Kogawa et al, 17 Kato et al, 18 Emshoff et al, 19 Venancio Rde et al 20 observed significant pain reduction using LASER therapy. The present study gives some evidence that by treating TMJ muscle we can eliminate cervical pain as well.…”

Aim:The aim of this study was to find out the therapeutic correlation between cervical dysfunction and myofascial pain dysfunction syndrome (MPDS). Materials and methods:The study included 46 patients out of which 23 had MPDS with cervical pain (group I), and 23 patients had only MPDS (group II). Detailed history and examination of the patients were carried out, and the factors taken into consideration were pain and tenderness of muscles of mastication and neck muscles, maximum comfortable mouth opening, and cervical range of motion. All the patients were randomly divided and advised physical exercises, light amplification by stimulated emission of radiation (LASER) therapy, and the combination of both exercise and LASER. Patients were assessed for the relief of signs and symptoms of myofascial pain and cervical pain posttreatment, every month for 2 months.Results: Both the groups showed a similar response to all the different treatment modalities. In group I, the patients also had relief in their cervical pain although the treatment was directed for MPDS. Patients from both the groups who were advised LASER and combination of both exercise and LASER showed better response in terms of reduction in visual analog scale, number of tender muscles, and increased maximum comfortable mouth opening posttreatment and during the follow-up, as compared with the patients who were advised only exercise. Conclusion:Patients having cervical pain showed significant improvement comparable with patients having no cervical pain. Hence, the conclusion drawn was that there is a positive Clinical significance: Cervical pain showed significant improvement to physiotherapy in the form of exercise, LASER, and combination treatment, though the effective modality was LASER and combination of exercise and LASER therapy.

ResumoO mioespasmo é uma alteração involuntária sustentada por mediação central. É uma alteração em que o músculo permanece contraído por alguns segundos, minutos ou mesmo dias e também é frequentemente observado durante tratamento em que necessitam de sessões prolongadas, como, por exemplo, tratamentos endodônticos de molares. Depois de determinado tempo, o paciente mostra instabilidade para manter a boca aberta, apresentando episódios de fechamento repentinos. Mioespasmos são facilmente reconhecidos pela disfunção estrutural que produzem. Descrever o diagnóstico de um caso de mioespasmo em paciente com mordida aberta anterior, otalgia e dor na própria ATM. A paciente M.M.S.R, 33 anos, gênero feminino, cor parda, compareceu ao atendimento na Policlínica da UEA para exame estomatológico de rotina. Durante a anamnese a paciente relatou que sentia dores de cabeça, dor de ouvido, apertamento dos dentes durante a noite e possuía o elemento 46 fraturado, relatou também ter ido ao dentista fazer a restauração do elemento dental 46 há aproximadamente um ano e que, passado alguns dias do procedimento começou a ter dores de cabeça frequentemente, porém a paciente relatou ser muito estressada. Por conseguinte, a etiologia dos mioespasmos não tem sido bem documentada. É provável que muitos fatores se combinem para promover o mioespasmo. Condições musculares locais certamente aparecem para criar mioespasmos: as dores de cabeça, de ouvido, dor facial, má oclusão aguda, dentre outros. Compete ao cirurgião-dentista diagnosticar e tratá-las em conjunto com outras especialidades. Descritores: Espasmo; Mialgia; Mordida Aberta; Otite; Transtornos da Articulação Temporomandibular. AbstractMyospasm is an involuntary alteration sustained by central mediation. It is a change in which the muscle remains seconds, minutes or even days and is also often observed during treatment requiring prolonged sessions, such as endodontic molar treatments. After some time, the patient shows instability to keep his mouth open, presenting sudden closure episodes. Myospasms are easily recognized by the structural dysfunction they produce. To describe the diagnosis of a case of myospasm in a patient with anterior open bite, otalgia and pain in the TMJ itself. The patient M.M.S.R, 33 years old, female, brown, attended the service in the UEA is polyclinic for routine stomatological examination. During the anamnesis the patient reported that she had headaches, earache, clenching of the teeth at night and had the fractured element 46, also reported having gone to the dentist to restore the dental element 46 about a year ago and that, a few days of the procedure began to have headaches frequently, but the patient reported being very stressed. Therefore, the etiology of myospasm has not been well documented. Many factors are likely to combine to promote myospasm. Local muscle conditions certainly appear to create myospasms: headaches, earaches, facial pain, acute malocclusion, among others. It is up to the dental surgeon to diagnose and treat them together wit...
