ABSTRACT AIMS: To evaluate the effect of light emitting diode (LED) therapy on temporomandibular disorder. CASE DESCRIPTION: A woman diagnosed with temporomandibular disorder was subjected to four LED therapy sessions at a seven-day interval. In the initial examination of the temporomandibular joint the patient presented a mouth opening without pain of 23 mm, a maximum opening of 25 mm and a maximum opening with the aid of 27 mm. After the treatment, there was an increase of 7 mm in the opening without pain between the first and last evaluation, while the maximum opening of the mouth and the maximum opening with aid increased 6 mm between the first and last evaluation. After 21 days of treatment, a 50% reduction in painful sites was detected on the palpation examination.After the end of the treatment, the visual analog pain scale detected a decrease in pain intensity on both sides, and there was a decrease in the total mean pain intensity. By analyzing the responses to the Medical Outcomes Study 36-item Short Form Health Survey (SF-36), of the eight quality of life domains evaluated, four showed improvement. CONCLUSIONS: In this case study, after LED therapy there was reduction in pain intensity and increase of the mandibular range of motion. The resolution of the signs and symptoms of temporomandibular disorder resulted in patient's better quality of life.KEY WORDS: temporomandibular joint dysfunction syndrome; phototherapy; low-level light therapy.

Bases Fisiopatológicas Da Aplicação Da Terapia a Laser De Baixa Intensidade No Herpes Zoster E Neuralgia Pós-Herpética Com Acometimento Orofacial

“…A biomodulação promovida pela TLBI favorece o aumento da endorfina circulante e o funcionamento da bomba de sódio/potássio alterando o limiar de dor (GARCEZ; RIBEIRO; NÚÑEZ, 2012). Costa et al (2017), observaram uma redução de 92% da intensidade de dor, mediante a aplicação da escala visual analógica em paciente com desordem temporomandibular (aguda), após a fototerapia. Gomes, Gomes e Nicolau (2016), realizaram uma revisão sistemática do efeito da TLBI na redução da dor em pacientes com NPHT e constataram que, em 100% dos artigos analisados, foram relatada melhora em relação à dor.…”

“…Contudo, nenhuma modalidade de uso clínico rotineiro tem mostrado ser totalmente eficaz na redução da sintomatologia dolorosa e nas manifestações da lesões (RANDOLPH; KAHN;SARAGA, 2013). A terapia com laser de baixa intensidade (TLBI) tem sido amplamente divulgada nos meios científicos e clínicos, devido o seu efeito positivo, na redução da dor, em uma série de condições, como fibromialgia, desordem temporomandibular, artrite reumatóide, dor pós-operatória, entre outras (RANDOLPH; KAHN;SARAGA, 2013;FALAKI;NEJAT;DALIRSANI, 2014;COSTA et al, 2017). No entanto, há poucos estudos sobre o uso da TLBI no tratamento na NPHT e não há estudos sobre o emprego da TLBI na HZ facial.…”

Association of facial massage, dry needling, and laser therapy in Temporomandibular Disorder: case report

“…Temporomandibular disorders (TMD) are defined as heterogeneous musculoskeletal and neuromuscular diseases that affect the stomatognathic system, and are characterized by intermittent pain or discomfort in the temporomandibular joint (TMJ), masticatory muscles, and adjacent tissues. It may also impair the most important orofacial functions: mastication, speech,, and yawning (1,2) .…”

“…Costa et al (1) point out that myogenic TMD is the most frequent condition among these patients. Myofascial pain is characterized by muscular hyperactivation and reduction in the normal blood flow of the muscle tissues, which leads to the accumulation of metabolism by products in this tissue, causing pain, inflammation, and fatigue (2) .…”

“…Furthermore, painful processes cause an intense release of angiogenic chemical mediators-such as phospholipids, which activate nociceptive receptors. With respect to inflammation, a local edema is formed and leukotriene and serotonin are released by virtue of the destruction of platelets (1) . Finally, in fatigue, the lactic acid accumulation that can compromise the musculature relaxation cycle is observed (5) .…”
