Abstract
Los TTM han sido definidos por la Academia Americana de Dolor Orofacial como un grupo de condiciones musculoesqueléticas y neuromusculares que afectan a las ATM, músculos masticatorios y tejidos asociados. Dentro de estos, el dolor miofascial es el trastorno muscular doloroso más común, con una prevalencia del 13% en la población general; caracterizado por un dolor regional sordo y la presencia de puntos gatillo que pueden producir patrones de dolor referidos característicos y/o síntomas autonómicos. El bruxismo es una actividad mandibular-muscular repetitiva caracterizada por el apretamiento y rechinamiento de los dientes y/o fijación o empuje de la madíbula. Tiene dos manifestaciones circadianas: puede ocurrir durante el sueño o la vigilia. Está asociado con varios problemas clínicos que pueden causar efectos negativos sobre las estructuras orales: problemas dentales (atrición o desgaste dental, fracturas o fracasos de tratamientos restauradores o implantes, necrosis dentaria por microtraumas, etc.); musculoesqueléticos (hipertrofia maseterina, dolor miofascial, dolor de la articulación temporomandibular) y cefaleas. Afecta a un 8% de la población general. A día de hoy, las actividades repetitivas o microtraumatismos, como el bruxismo, son considerados factores importantes en el desencadenamiento y perpetuación del dolor en TTM. Se ha sugerido que el bruxismo es un factor de riesgo de dolor miofascial de los músculos masticatorios. La frecuencia de asociación entre TTM y bruxismo en adultos está entre 36,0% y 59,3%...
Temporomandibular disorders (TMD) can be defined as a group of musculoskeletal and neuromuscular conditions that involve the TMJs, the masticatory muscles, and all associated tissues. Among TMD conditions, muscle disorders are the most common. Masticatory muscle pain such as myofascial pain has a prevalence of up to 13% in the general population. Myofascial pain is characterized by the presence of local myalgia and trigger points that can provoke referral pain beyond the boundary of muscles and autonomic symptoms may be present. Bruxism is a repetitive jaw-muscle activity characterized by clenching or grinding of the teeth and/or by bracing or thrusting of the mandible. It has two distinct circadian manifestations: it can occur during sleep (indicated as sleep bruxism) or during wakefulness (indicated as awake bruxism). Tooth grinding is an activity of major concern to dentists because of its consequences: tooth destruction, breakage of dental restoration or rehabilitation, exacerbation of TMDs or induction of temporal tension headache. It affects 8% of the general population. At present, repetitive activities or microtrauma, such as bruxism, are considered important factors in triggering and perpetuation of pain in TMDs. It has been suggested that bruxism is a risk factor for myofascial pain of masticatory muscles. Even though there are clear associations between bruxism and craniofacial pain, we must be cautious to not to infer a direct causal relationship. The frequency of association between TMDs and bruxism in adults is between 36% and 59%...
