“…According to the other authors (Glaros et al, 1997;Gonzalez et al, 2008) one of the limitations of EMG diagnosis highlighted in this study is the inability to clearly distinguish pain from nonpain subjects. .…”

“…To our knowledge, the magnitude of EMG activity of the jaw muscles in patients with chronic, unilateral TMD has not been documented, and the diagnostic value of EMG tests is yet to be established (Gonzalez et al, 2008;Suvinen and Kemppainen, 2007). This cross-sectional study of clench-EMG activity of jaw muscles assessed three null hypotheses: (1) there are no differences between symptom-free and unilateral TMD subjects, (2) there are no differences between patients suffering from right side TMD in contrast to those suffering from left side TMD, and (3) there are no differences between the pain and non-pain sides of unilateral TMD patients.…”

The study assessed the differences in electromyographic (EMG) activity recorded during clenching in women with chronic unilateral temporomandibular disorders (TMDs) as compared to control subjects. Seventy-five full dentate, normo-occlusion, right-handed, similarly aged female subjects were recruited. Twenty five subjects presented with right side TMD, 25 presented with left side TMD and 25 pain-free control subjects participated. Using integrated surface EMG over a 1 s contraction, the anterior temporalis and masseter muscles were evaluated bilaterally while subjects performed maximum voluntary clenching. Lower EMG activation was observed in patients with TMD as compared to control subjects (temporalis: 195.74+/-18.57 vs. 275.74+/-22.11, P=0.011; masseters: 151.09+/-17.37 vs. 283.29+/-31.87, P<0.001). An asymmetry index (SAI) was calculated to determine ratios of right to left sided activation. Patients with right-sided TMD demonstrated preferential use of their left-sided muscles (SAI -5.35+/-4.02) whereas patients with left-sided TMD demonstrated preferential use of their right-sided muscles (SAI 6.95+/-2.82), (P=0.016). This unilateral reduction in temporalis and masseter activity could be considered as a specific protective functional adaptation of the neuromuscular system due to nociceptive input. The asymmetry index (SAI) may be a useful measure in discriminating patients with right vs. left-sided TMD.

“…Due to the multifactor etiology of this condition, the precise diagnosis remains a matter of debate (Medllicott and Harris, 2006) and validated diagnostic tools are needed (Gonzalez et al, 2008). Electronic equipment may provide reliable quantitative data to assist in the clinical evaluation of TMD (Schmitter et al, 2005;Manfredini et al, 2006;Hugger et al, 2008;Lauriti et al, 2014).…”

Rev Nac Odontol. 2015;11(20):83-93. doi: http://dx.doi.org/10.16925/od.v11i20.748 Resumen. Los trastornos temporomandibulares (ttm) constituyen una afección que provoca síntomas como dolor, lo cual es uno de los principales motivos de consulta odontológica. Sin embargo, con frecuencia los pacientes en los estadios iniciales ignoran la sintomatología, o es quizá en una etapa más avanzada que deciden acudir a consulta, ya sea por presentar dolor incapacitante en regiones del sistema gnático o como consecuencia del escaso conocimiento en la comunidad sobre estos trastornos. Estas dos situaciones promueven muchas veces la evolución desfavorable y la complicación del cuadro clínico, que es sin duda competencia del área de odontología. Aunado a lo anterior, los ttm suelen compartir con otras enfermedades algunos signos, síntomas y factores asociados a su etiología. Por esto, el odontólogo general sin especialidad se enfrenta al reto de atender en su consulta diaria a pacientes que pueden mostrar alguna de las manifestaciones de ttm durante una evaluación odontológica de rutina o por otro motivo. Debido a lo anterior, los odontólogos generales deben tener conocimiento y acceso a información que posibilite el desarrollo de habilidades y competencias básicas, para identificar factores etiológicos asociados con ttm y registrar información pertinente que contribuya con el diagnóstico temprano, con el fin de evitar la pérdida de tiempo y orientar al paciente hacia la atención especializada de manera más oportuna.Palabras clave: articulación temporomandibular, diagnóstico, etiología, oclusión dental, trastornos de la articulación temporomandibular.
