“…Contrarily, as to the opening speed, there was a significant statistical difference only between pain degree zero and pain degree three, that is, between absence of pain and severe pain. This finding agrees with Garcia et al (2000), who point out limitations of movements associated to intense pain, and with Jankelson (1990) that shows cases of important reduction of speed associated with myositis and advanced degenerative alterations and articular pain.…”

“…In this study, it was observed that the presence of pain, which is characteristic of these dysfunctions, determines a sign of opening amplitude reduction, and no evidences were found as to the worsening of this sign with the increase of pain. Thus, the reference of functional limitations due to intense pain associated to the progression of temporomandibular dysfunctions is not confirmed (Garcia et al, 2000). Concerning protrusive and retrusive movements, no differences were observed between the four pain degrees analyzed, suggesting that the pain seems not to interfere in these movements during speech.…”

“…Literature about signs and symptoms of temporomandibular dysfunctions indicates asymmetry of mandibular movements in general, and deviations in mandibular course associated to presence of pain, hyperactivity of lateral pterygoid muscle, inflammatory process, incorrect relation condyle/disc, and TMJ morphological alterations (Garcia et al, 2000). As to the characterization of mandibular movements during speech, scarce previous researches point out the verification of important mandibular movement deviations.…”

“…In the literature there are reports concerning the symptoms and signs worsening observed in patients, such as functional limitations due to intense pain associated to temporomandibular dysfunctions progression (Garcia et al, 2000). Thus, clinical signs, including those indicative of internal derangement, become more meaningful where there is associated pain (Luz, 2000;Conti et al, 2000).…”

“…The generic term tenmporomandibular dysfunction includes two essential groups of dysfunctions: the muscular ones and the intraarticular, or just articular ones (Okeson,1997;Goldstein,1999;Luz,2000;Garcia et al,2000;Mazzonetto & Spagnoli, 2001;Nassif & Talic,2001). In this research, participants were not subdivided concerning these groups, despite the recognition of the importance of such classification.…”

Background: temporomandibular disorders can cause general alterations of the mandibular movements due to modification in the condition of muscles and articulations. Electrognathography, a computerized exam used to complement the diagnosis of these disorders, allows the objective delineation and record of the mandibular movements, determining their amplitude and speed. Aim: to verify the characteristics of mandibular movements of individuals with temporomandibular dysfunction and in asymptomatic individuals during speech, through computerized electrognathography, analyzing possible interferences of this dysfunction and severity implications regarding pain indexes. Method: 135 adults were divided in four groups based on their pain indexes, using a numeric scale: zero for pain absence, one for mild pain, two for moderate pain and three for severe pain. Mandibular movements were observed during the sequential naming of balanced pictures taking in consideration the occurrence of phonemes in the Brazilian Portuguese language. Records were obtained using computerized electrognathography (BioEGN -BioPak system). Results: the analysis of the results point that differences indicated as significant for mandibular opening amplitude and mandibular closing speed occurred between index zero and all of the other pain indexes. Regarding mandibular opening speed during speech, statistically significant differences were obtained between index zero and index three. It was observed that mandibular movements in speech are discreet, with an anteroposterior component and deviations in laterality. Conclusion: the presence of temporomandibular dysfunctions causes reduction in the values of maximum mandibular opening and a reduction in both mandibular opening speed and mandibular closing speed during speech The different pain indexes: mild, moderate and severe do not seem to determine larger reduction of these values.

ResumoTema: as disfunções temporomandibulares podem acarretar alterações gerais nos movimentos mandibulares devido à modificação nas condições musculares e articulares. A eletrognatografia, exame computadorizado utilizado para complementar o diagnóstico dessas disfunções, permite delinear e registrar de maneira objetiva os movimentos mandibulares, determinando sua amplitude e velocidade. Objetivo: verificar as características do movimento mandibular na fala em indivíduos com disfunções temporomandibulares e em assintomáticos, por meio de eletrognatografia computadorizada, analisando possíveis interferências dessas disfunções e as implicações de severidade quanto ao índice de dor. Método: 135 participantes adultos foram divididos em quatro grupos com base nos graus de dor, utilizando-se escala numérica, sendo: zero para ausência de dor, um para dor leve, dois para dor moderada e três para dor grave. Os movimentos mandibulares foram observados na nomeação seqüencial de figuras balanceadas quanto à ocorr...

There are conflicting opinions about the frequency range of temporomandibular joint (TMJ) sounds. Some authors claim that the upper limit is about 650 Hz. The aim was to test the hypothesis that TMJ sounds may contain frequencies well above 650 Hz but that significant amounts of their energy are lost if the vibrations are recorded using contact sensors and/or travel far through the head tissues. Time-frequency distributions of 172 TMJ clickings (three subjects) were compared between recordings with one microphone in the ear canal and a skin contact transducer above the clicking joint and between recordings from two microphones, one in each ear canal. The energy peaks of the clickings recorded with a microphone in the ear canal on the clicking side were often well above 650 Hz and always in a significantly higher area (range 117-1922 Hz, P < 0.05 or lower) than in recordings obtained with contact sensors (range 47-375 Hz) or in microphone recordings from the opposite ear canal (range 141-703 Hz). Future studies are required to establish normative frequency range values of TMJ sounds but need methods also capable of recording the high frequency vibrations.
