Key inclusion & exclusion criteria

Inclusion criteria: Female gender, non-smokers, normotensive, age group between 18 and 40 years, with diagnosis of temporomandibular disorder, presenting orofacial chronic pain (Gratt, Anbar 2005), which suggest that chronic pain is the pain that persists for more than four months, body mass index (BMI) normal and overweight (normality value of 18.5 to 27.5 Kg/m2) sent to physiotherapeutic treatment.

Exclusion criteria: Volunteers with medical and/or dental emergencies, metabolic diseases (such as diabetes or hyperthyroidism), neurological disorders (e.g. , disquinesia and/or neuralgia of the trigeminus nerve etc. ), vascular disease (for example, hypertension), cancer, past history of psychiatric disorders, drug abuse, pregnant or breastfeeding women, history of recent accidents with powered vehicle, volunteers currently treated with medications for neurological disorders or psychological and making use of analgesics or nsaids, were also excluded.

Temporomandibular disorders (TMD) myofascial chronic pain in TMD
C05.550.091

Intervention(s)

Each volunteer followed the sequence:
Clinical evaluation of volunteer with a clinical diagnosis of Temporomandibular Disorders;
Eletrocardiogram during 15 minutes of rest and 15 minutes inclined to heart rate variability analysis;
The register of pain intensity in the visual analog scale before each low level laser application and after 5 minutes of the end;
Collection of peripheral blood for cortisol analysis;
10 interventions with low level laser on alternate days, with a frequency of 3 times per week;
Reevaluation of patients with a clinical diagnosis of Temporomandibular Disorders;
Eletrocardiogram for analysis of heart rate variability after 10 sessions
of low level laser therapy;
Collection of peripheral blood after 10 sessions of low level laser therapy.

Primary Outcome(s)

The results :

The analgesic therapeutic with Laser increased the blood cortisol levels measured in the blood and within normal parameters;
Reduced muscle tension of the face and head muscles verified by increase of the range of motion of the mandibular movements measured in millimeters with a pachymeter and lower levels of pain on palpation by physical examination;
LLLT applied for pain of the volunteers Reduced the increase in sympathetic nerve activity on the heart, spectrum of very low frequency (VLF) and spectra of low frequency (LF)measured by analysis of the eletrocardiogram.
