RESUMO

Osteoarthritis is one of the most frequent pathologies affecting the temporomandibular joint (TMJ). There is evidence that the use of intra-articular hyaluronic acid (HA) for the treatment of this disorder achieves positive effects through a reduction in inflammatory mediators. A systematic review of the available evidence regarding the regulation of inflammatory mediators when applying HA in osteoarthritis of the TMJ in humans was performed. The Web of Science, Embase, ScienceDirect, MEDLINE, Scopus, EBSCOhost, and LILACS databases, SciELO library, and search engine Trip Database were searched systematically. Two thousand eight hundred and sixty-three related articles were found, of which only two met the selection criteria (both were clinical trials and evidence level 2b for treatment studies). These two articles represented a population of 87 patients. Both articles reported that the application of HA had a positive effect on the regulation of inflammatory mediators; the mediators studied were those of the plasminogen activator system and levels of nitric oxide. The limited evidence available suggests that the application of HA regulates various inflammatory mediators in osteoarthritic processes in the TMJ. Nevertheless, further evidence in this regard is required, through the study of specific pathologies of the TMJ, complementing the assessment of clinical parameters with molecular studies, and generating good quality clinical studies with larger sample sizes.

RESUMO

Bruxism (BRX) is a condition of great interest for researchers and clinicians in dental and medical areas. BRX has two circadian manifestations; it can occur during sleep (sleep bruxism, SB) or during wakefulness (awake bruxism, WB). However, it can be suffered together. Recent investigations suggest that central nervous system neurotransmitters and their genes could be involved in the genesis of BRX. Serotonin is responsible for the circadian rhythm, maintaining arousal, regulating stress response, muscle tone and breathing. Thus, serotonin could be associated with BRX pathogenesis. The aim of this work was to evaluate the frequency of genetic polymorphisms in the genes HTR1A (rs6295), HTR2A (rs1923884, rs4941573, rs6313, rs2770304), HTR2C (rs17260565) and SLC6A4 (rs63749047) in subjects undergoing BRX treatment. Patients included were classified according to their diagnosis in awake bruxism (61 patients), sleep bruxism (26 patients) and both (43 patients). The control group included 59 healthy patients with no signs of BRX. Data showed significant differences in allelic frequencies for the HTR2A rs2770304 polymorphism, where the C allele was associated with increased risk of SB (odds ratio = 2·13, 95% confidence interval: 1·08-4·21, P = 0·03). Our results suggest that polymorphisms in serotonergic pathways are involved in sleep bruxism. Further research is needed to clarify and increase the current understanding of BRX physiopathology.

RESUMO

Artralgia de la articulación temporomandibular (ATM) es un término utilizado en los criterios diagnósticos para los trastornos temporomandibulares (CD-TTM) definido como dolor de origen articular que se ve aumentado por el movimiento mandibular, ya sea en función o parafunción, y la replicación de este dolor mediante la palpación de la ATM. En relación al manejo de la artralgia, la evidencia describe diferentes tipos de terapias, las cuales se pueden clasificar en invasivas y no invasivas. Las terapias farmacológicas, cognitivo conductuales y el uso dispositivos interoclusales se encuentran dentro de la categoría de terapias no invasivas. Los dispositivos interoclusales tipo pivot, han sido ampliamente utilizados en el alivio de artralgias de ATM. Se describe un 70% de alivio del dolor con el uso de éstos dispositivos en pacientes con artralgias de ATM. El objetivo de esta revisión es evaluar la evidencia encontrada respeto de los dispositivos tipo pivot bilaterales y sus resultados como tratamiento en artralgias de ATM (AU)


Arthralgia of Temporomandibular Joint is a term used in the Diagnostic Criteria for Temporomandibular Disorders (DC-TMD), defined as pain of joint origin that is affected by jaw movement, function, or parafunction, and replication of this pain occurs with provocation testing of the TMJ. In the management of Arthralgia the evidence describes different types of therapies, which can be classified as invasive and non-invasive. The pharmacological and cognitive behavioural therapies, as well as the use of interocclusal appliances are considered among the non-invasive therapies. The interocclusal pivot appliances have been widely used to relieve the TMJ arthralgia. The action mechanism of these appliances would be produced by a distraction of the TMJ as a result of the downward movement of the mandibular condylar process; as an added effect it also lowers the intrarticular pressure. Current evidence describes a 70% of pain relief in patients with TMJ arthralgia. The aim of this review is evaluating the evidence found in bilateral pivot appliances and their results as a treatment for TMJ arthralgia (AU)

RESUMO

El dolor miofascial es una patología muscular regional no inflamatoria caracterizada por la presencia de una zona hiperirritable de tejido muscular que se encuentra en una banda tensa, denominado punto gatillo. En la región orofacial pertenece a un conglomerado de patologías denominadas trastornos temporomandibulares, correspondiendo al de mayor prevalencia. Las manifestaciones clínicas van desde dolor local, tensión muscular y disfunción estructural hasta dolor referido, fenómenos autonómicos e hiperexcitabilidad en el sistema nervioso central. Durante las últimas décadas se han asociado variantes genéticas con diferentes expresiones en patologías dolorosas, algunas de las cuales se encuentran en el sistema GABAérgico. En el presente artículo se realiza una revisión del dolor miofascial como patología y su relación con estos polimorfismos genéticos (AU)


Myofascial pain is noninflammatory regional muscular disorder characterized by the presence of a muscle tissue area hyperirritable located on a taut band, called trigger point. In the orofacial region myofascial pain belongs to a cluster of diseases called temporomandibular disorder. Within these pathologies, it is to the most prevalent of its, clinical manifestations include local pain, muscle tension, structural dysfunction, referred pain, autonomic phenomena and hyperexcitability in the central nervous system. During the last decades have been associated genetic variants to painful pathologies, some of which are in the GABAergic system. This article performs a review of myofascial pain as pathology and its relation to genetic polymorphisms in GABAergic system (AU)

RESUMO

Los trastornos temporomandibulares son un grupo heterogéneo de alteraciones funcionales que afectan al aparato masticatorio y reducen la calidad de vida de los pacientes. Dentro de estos trastornos encontramos las alteraciones del complejo cóndilo disco, los cuales son factores de riesgo para la generación de patologías degenerativas articulares de la articulación temporomandibular (ATM). El tratamiento de los procesos degenerativos articulares es controversial ya que se han utilizado a través del tiempo variadas estrategias terapéuticas; desde la utilización de dispositivos ortopédicos mandibulares, pasando por terapias invasivas como la artrocentesis o irrigación y drenaje de los espacios articulares, hasta la infiltración de fármacos dentro del espacio articular. Tradicionalmente la infiltración intra articular de fármacos se ha efectuado con glucocorticoides debido a su efecto antiinflamatorio y analgésico; sin embargo, hace más de dos décadas ha surgido la utilización del ácido hialurónico, cuyo efecto antiinflamatorio y de viscosuplementación ha demostrado poseer gran utilidad terapéutica en procesos degenerativos a nivel articular. Clínicamente, sin embargo, este fármaco carece de un protocolo que forme el esquema terapéutico en cuanto a concentración, dosis, frecuencia y extensión del tratamiento en su uso en patologías degenerativas óseas de la ATM. Por lo tanto, surge la necesidad de revisar la evidencia existente al respecto en estudios experimentales realizados en humanos o animales. Se realizó una revisión de la evidencia disponible online, la que luego de un proceso de análisis y selección obtuvo 11 estudios en humanos y 4 en animales, los autores no encontraron pruebas científicas suficientes para establecer un protocolo de infiltración de ácido hialurónico en patologías degenerativas de la articulación temporomandibular


Temporomandibular disorders are a heterogeneous group of functional disorders affecting the masticatory system, reducing the quality of life of patients. Within these disorders find the disc condyle complex disorders, which are risk factors for the generation of degenerative joint diseases of the temporomandibular joint (TMJ). The treatment of joint degenerative processes is controversial, and have been used over time varied therapeutic strategies, since the use of mandibular orthopedic devices, through invasive therapies such as arthrocentesis or irrigation and drainage of the joint spaces; drugs to infiltration into the joint space. Traditionally the intra infiltration articular drug was performed with glucocorticoids due to its anti-inflammatory and analgesic effect, however more than two decades ago has emerged using the hyaluronic acid, the inflammatory and viscosupplementation effect has demonstrated great therapeutic usefulness in degenerative processes articular level. Clinically this drug however lacks a protocol that regulates the therapeutic regimen in strength, dosage, frequency and extent of treatment in use in bone degenerative diseases of the TMJ. Thus arises the need to review the existing evidence on this in experimental studies in humans or animals. A review of the evidence was made available online, which after a process of analysis and selection scored 11 studies in humans and 4 in animals, the authors found insufficient evidence to establish a protocol infiltration of hyaluronic acid in degenerative pathologies temporo mandibular joint

RESUMO

Los trastornos temporomandibulares son un conjunto amplio de patologías dentro de las cuales están las adherencias discales. Estas son una fijación permanente del disco articular a una de las superficies, debido a un aumento de la carga estática articular y posterior colapso del espacio articular superior o inferior, siendo provocado por una unión fibrótica entre estas superficies. Es necesario aumentar el reconocimiento de esta patología para su diagnóstico y tratamiento oportuno, por lo que el objetivo de este artículo es realizar una revisión en cuanto a la epidemiología, etiopatogenia, diagnóstico y tratamiento de la adhesión discal de la articulación temporomandibular (AU)


Temporomandibular joint disorders are a wide range of conditions where there are the intraarticular adhesions of the temporomandibular joint. These are a permanent attachment to the articular disk surface due to an increase of static load and collapse articular joint space above or below, being caused by a fibrotic joint between these surfaces. It´s necesary increase the recognition of this disease for an appropiate diagnosis and treatment, so the aim of this paper is to review regarding the epidemiology, pathogenesis, diagnosis and treatment of the discal adherence of the temporomandibular joint (AU)

RESUMO

El dolor miofascial es una patología muscular regional no inflamatoria que en el territorio craneocervical se encuentra clasificada dentro de los Trastornos Temporomandibulares. Afecta al 95% de las personas con trastornos de dolor crónico y es un hallazgo común en pacientes en tratamiento en centros de dolor. Se revisaron 121 fichas de pacientes atendidos en el policlínico de Trastornos Temporomandibulares y Dolor Orofacial de la Universidad de La Frontera, Temuco-Chile, identificando la prevalencia de dolor miofascial y su asociación con la edad y sexo de los pacientes. El 80,99% de los pacientes presentó dolor miofascial, el músculo masetero fue el más afectado, seguido por los músculos temporal y trapecio superior, siendo frecuente la afectación bilateral y simultánea de diferentes músculos. La presencia de dolor miofascial no se asocia a la edad de los pacientes pero si al sexo de estos, donde las mujeres presentan más frecuentemente esta patología. Es importante realizar un correcto diagnóstico de dolor miofascial en pacientes que acuden por dolor en este territorio y más aún es trascendental tomar conciencia de su elevada prevalencia.


Myofascial pain is a noninflammatory regional muscle pathology, in craniocervical territory it is classified as temporomandibular disorder. Myofascial pain affects 95% of people with chronic pain disorders and is a common finding in pain centers. One hundred twenty-one charts of patients seen at the clinic of Temporomandibular Disorders and Orofacial Pain at the Universidad de La Frontera Temuco-Chile, were reviewed, identifying the prevalence of myofascial pain and its association with age and sex of the patients. In 80.99% of patients myofascial pain was present, the masseter muscle was the most affected, followed by the temporal and upper trapezius muscles, with frequent bilateral and simultaneous involvement of different muscles. The presence of myofascial pain is not associated with patient age but it is associated with the sex of these, where women have this condition more often. It is important to make a correct diagnosis of myofascial pain in patients presenting with pain in this area and it is even more crucial to be aware of its high prevalence.

RESUMO

La anquilosis de la articulación temporomandibular (ATM) corresponde a un trastorno temporomandibular clasificado dentro de la hipomovilidad mandibular crónica. La literatura define anquilosis como una inmovilidad anormal de la mandíbula, desorden que lleva a una restricción de la apertura bucal con reducción parcial de los movimientos mandibulares o una completa inmovilidad de la mandíbula. El objetivo del presente artículo es realizar una revisión en cuanto a la clasificación, epidemiología, etiopatogenia, diagnóstico y tratamiento de la anquilosis de la articulación temporomandibular (AU)


Ankylosis of the temporomandibular joint (TMJ) corresponds to a temporomandibular disorder classified into chronic mandibular hypomobility. Ankylosis defines literature as an abnormal jaw immobility disorder that leads to a restriction of mouth opening with partial reduction of mandibular movement or complete immobility of the jaw. The aim of this article is to review the classification, epidemiology, etiology, diagnosis and treatment of temporomandibular joint ankylosis (AU)
