“…The displaced disc is commonly anterior; however, sideway displacement has been reported [1,2]. MR imaging is the most accurate imaging modality for accurate localization of disc position and its pattern of displacement and considered as the gold standard for assessment of TMJ but it is expensive, not readily available [3][4][5][6].…”

Purpose To assess pattern of articular disc displacement in patients with internal derangement (ID) of temporomandibular joint (TMJ) with ultrasound. Materials and methods Prospective study was conducted upon 40 TMJ of 20 patients (3 male, 17 female with mean age of 26.1 years) with ID of TMJ. They underwent highresolution ultrasound and MR imaging of TMJ. The MR images were used as the gold standard for calculating sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), and negative likelihood ratio (NLR) of ultrasound for diagnosis of anterior or sideway displacement of the disc. Results The anterior displaced disc was seen in 26 joints at MR and 22 joints at ultrasound. The diagnostic efficacy of ultrasound for anterior displacement has sensitivity of 79.3 %, specificity of 72.7 %, accuracy of 77.5 %, PPV of 88.5 %, NPV of 57.1 %, PLR of 2.9 and NLR of 0.34. The sideway displacement of disc was seen in four joints at MR and three joints at ultrasound. The diagnostic efficacy of ultrasound for sideway displacement has a sensitivity of 75 %, specificity of 63.6 %, accuracy of 66.7 %, PPV of 42.8, NPV of 87.5 %, PLR of 2.06, and NLR of 0.39. Conclusion We concluded that ultrasound is a non-invasive imaging modality used for assessment of anterior and sideway displacement of the articular disc in patients with ID of TMJ.Riassunto Scopo Valutare i pattern della dislocazione del disco articolare nei pazienti con squilibrio interno (ID) dell'articolazione temporo-mandibolare (ATM) con l'ecografia. Materiale e metodi E' stato condotto uno studio prospettico su 40 ATM di 20 pazienti (3 maschi, 17 femmine, con età media di 26,1 anni) con ID della TMJ. Tutti sono stati sottoposti ad ecografia ad alta risoluzione e RM della TMJ. La RM è stati utilizzata come il gold standard per il calcolo di sensibilità, specificità, accuratezza, valore predittivo positivo (PPV), valore predittivo negativo (NPV), rapporto di probabilità positivo (PLR) e rapporto di probabilità negativo (NLR) dell'ecografia nella la diagnosi di dislocazione anteriore o lateralmente del disco. Risultati Il disco appariva dislocato anteriormente in 26 ATM con la MR e in 22 con l'ecografia. L'efficacia diagnostica dell'ecografia nella diagnosi di dislocazione anteriore aveva sensibilità del 79,3 %, specificità del 72,7 %, accuratezza del 77,5 %, valore predittivo positivo del 88,5 %, NPV di 57,1 %, PLR di 2,9 e NLR di 0,34. Il dislocamento laterale del disco è stata osservato in 4 casi con MR e 3 con ecografia. L'efficacia diagnostica dell'ecografia per lo spostamento laterale aveva sensibilità del 75 %, specificità del 63,6 %, accuratezza del 66,7 %, PPV di 42,8, NPV di 87,5 %, PLR di 2.06 e NLR di 0,39. Conclusioni Abbiamo concluso che l'ecografia è una metodica di imaging non invasiva che può essere utilizzata per la valutazione delle dislocazioni anteriori e laterali del disco articolare nei pazienti con ID di TMJ.

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.

“…Sample size was calculated using Raosoft, 2014 (Raosoft, Inc.; Seattle, WA, USA), with a margin of error of 5%, confidence level of 95%, and prevalence of 38.6% for painful TMD 6 . The size obtained by the software was 107 patients from a total of 150 new patients treated at the dental service during the course of this study.…”

“…Prevalence of myofascial pain was 80.99%. TMDs are the second leading cause of pain in the orofacial region, after odontogenic pain 6 . Patients with orofacial pain are usually evaluated by different clinicians who, before finding the correct diagnosis 7 , give different diagnoses and prescribe treatment options that do not necessarily treat the source of this condition.…”

Aim: To determine pain frequency by means of a clinical screening questionnaire in patients with temporomandibular disorders (TMD) referred to the general Hospital of Valdivia (HBV) between September and December 2014. Material and method: A descriptive study, which included patients referred to the TMD Unit of the dental service at HBV between September and December 2014, was carried out. A clinical screening questionnaire was applied by an examiner in order to detect painful Temporomandibular Joint Disorders. The variables age, sex, wait time, and presence of related TMD pain were measured. Results: 101 patients were surveyed; 88.17% (84 patients) were women. Average age was 33.5 (11-70) years; 66% of patients had mandibular pain or stiffness upon awakening; 80% informed pain related to painful TMD. Conclusion: Most surveyed patients were women. Pain was highly frequent in the surveyed population; its main location was in temporal areas.
