Estudo comparativo entre duas técnicas radiográficas transcranianas utilizando o cefalostato Accurad-200, nas posições padrão e corrigida, e confecção de gabaritos para delimitação dos espaços articulares

Abstract: Este estudo teve como finalidades realizar uma análise comparativa entre duas técnicas radiográficas transcranianas com o auxílio do cefalostato ACCURAD-200, nas posições padrão e corrigida, e desenvolver um gabarito que auxilie o profissional a medir os espaços articulares anterior e posterior, fornecendo informações sobre o posicionamento condilar. Foram radiografados 59 pacientes, numa faixa etária entre 18 e 35 anos, que voluntariamente se propuseram a participar deste estudo. A correção da incidência do f… Show more

“…Once, no significant statistical differences were found between the pain degrees proposed in this study, it seems important to verify variations regarding the classification of temporomandibular dysfunctions proposed by several authors mentioned here (Garcia et al,2000;Mazzonetto & Spagnoli,2001;Nassif & Talic,2001) in further studies concerning the characterization of mandibular movements during speech in individuals with such dysfunctions, despite the difficulties of researches derived from this classification (Tasaki et al,1996;Palácios-Moreno et al,1997;Almeida et al,1997) The use of computerized electrognathography in this research as an investigation tool of these characteristics was an efficient measuring method, providing objective data concerning these movements.…”

“…The exams would also have be requested for the asymptomatic group, submitting these patients to the difficulty and consequences of such complementary exams. Furthermore, literature points out some difficulties of data interpretation of these exams depending on the technique and criteria adopted (Palácios-Moreno et al Almeida et al,1997) and, mainly, the existence of some morphological alterations in articular surfaces and modified condylar position also in asymptomatic individuals (Tasaki et al, 1996). Thus, the temporomandibular dysfunctions characterization for this research took into account clinical data, in special the presence of muscular and/or articular chronic pain, and at least three discrete signs described in the literature (Luz, 2000, Palácios-Moreno et al, 2001.…”

“…Several anatomical and technical factors can prevent a clear and unobstructed radiographic image of the TMJ. 16 , 17 When choosing TMJ radiography, one needs to consider the identification of boney structural details, the specific suspected clinical disorder, the amount of symptomatic information clinically available for the diagnosis, the cost of these examinations, and their radiation dose. 3 , 14 The radiographic techniques most often used in the routine management of TMJD are panoramic radiography, planigraphy, and transcranial radiography 1 , 3 , 13 , 15 ( Fig.…”

“…Os aspectos imagenológicos do desarranjo interno são de difícil interpretação nas radiografias convencionais. A análise das estruturas da ATM pode deixar dúvidas, devido à sobreposição de estruturas densas adjacentes (Almeida et al, 1997). Atualmente, a ressonância nuclear magnética possibilita avaliar as estruturas articulares de tecidos duros e moles, quanto à sua forma e possibilidade de movimentação (Tasaki et al, 1996;Luz, 2000).…”

“…O termo genérico disfunções temporomandibulares abriga dois grupos essenciais de disfunções: as musculares e as intra-articulares, ou simplesmente articulares (Liu et al, 1989;Holmlund et al, 1989;Muir e Gloss, 1990;Ishigaki et al, 1994;Okeson, 1997;Goldstein, 1999;Luz, 2000;Garcia et al, 2000;Mazzonetto e Spagnoli, 2001;Nassif & Talic, 2001). (Muir e Goss, 1990;Eliasson e Isacssom, 1992;Palácios-Moreno et al, 1997;Almeida et al, 1997) e, principalmente, a existência de algumas alterações morfológicas nas superfícies articulares e posição condilar modificada também em indivíduos assintomáticos (Weinberg, 1985;Muir e Goss, 1990, Tasaki et al, 1996. Assim, a caracterização das disfunções temporomandibulares para essa pesquisa levou em conta os dados clínicos, em especial a presença de dor muscular e/ou articular crônica, além de ao menos três sinais descritos na literatura em questão (Mc Neill, 1990;Correia, 1991;Luz, 2000, Palácios-Moreno et al, 2001).…”
