Summary: | Objective: To evaluate the position and morphology of the condyle and articular disc of the temporomandibular joints (TMJs), using magnetic resonance imaging (MRI), in children and adolescents with Class III and/or Angle subdivision malocclusion. Methods: The group consisted of 78 white and brown Brazilian patients, of both genders (47 girls and 31 boys), with an average chronological age of 9.5 years, with a total of 156 ATMs. MR images were acquired at the beginning of the treatment period. A qualitative assessment was carried out, by two observers, of the aforementioned structures, in closed mouth (BF) positions with maximum habitual intercuspation and open mouth (BA). Non-parametric tests of intra- and inter-observer assessments were performed. Results: In the position of the condyles in BF, 128 TMJs (82.1%) were concentric. In BA, 44 TMJs (28.2%) had normal mobility, in 59 TMJs (37.8%) they had hypomobility and 53 TMJs (34.0%) had hypermobility. In the position of the articular disc with BF, in 125 TMJs (80.1%) the discs were well positioned, in 31 TMJs (19.9%) they were displaced. With BA, the disc remained interposed in 125 TMJs (80.1%) and in 31 TMJs (19.9%) disc displacement with reduction. In 139 TMJs (89.1%), the morphology of the condyle was normal, in 17 TMJs (10.9%) they were remodeled. In the shape of the disc with BF and BA, in 147 ATMs (94.2%) and 156 ATMs (100.0%), respectively, it was biconcave. Conclusion: Important signs of temporomandibular disorders were found, mainly displacement of the articular disc. Longitudinal monitoring and future investigations should be considered. |

Métodos: O grupo constou de 78 pacientes brancos e pardos, brasileiros, de ambos os gêneros (47 meninas e 31 meninos), com idade cronológica média de 9,5 anos, num total de 156 ATMs. As imagens da RM foram adquiridas ao início do período de tratamento. Foi realizada uma avaliação qualitativa, por dois observadores, das referidas estruturas, nas posições de boca fechada (BF) com máxima intercuspidação habitual e boca aberta (BA). Testes não paramétricos de avaliações intra e interobservadores foram realizados. Resultados: Na posição dos côndilos em BF, 128 ATMs (82,1%) apresentavam-se concêntricos. Em BA, 44 ATMs (28,2%) os côndilos estavam com mobilidade normal, em 59 ATMs (37,8%) hipomobilidade e 53 ATMs (34,0%) hipermobilidade. Na posição do disco articular com BF, em 125 ATMs (80,1%) os discos estavam bem posicionados, em 31 ATMs (19,9%) apresentavam-se deslocados. Com BA, o disco manteve-se interposto em 125 ATMs (80,1%) e em 31 ATMs (19,9%) deslocamento disco com redução. Em 139 ATMs (89,1%), a morfologia do côndilo apresentou-se normal, em 17 ATMs (10,9%) estavam remodelados. Na forma do disco com BF e BA, em 147 ATMs (94,2%) e 156 ATMs (100,0%), respectivamente, apresentou-se bicôncava. Conclusão: Foram encontrados importantes sinais de desordens temporomandibulares, principalmente o deslocamento no disco articular. O acompanhamento longitudinal e futuras investigações devem ser considerados.CapesSudeste-1application/pdfapplication/pdfapplication/pdfapplication/pdfporUNIFESPDepartamento de Diagnóstico por ImagemBrasilUniversidade Federal de São PauloopenAccessinfo:eu-repo/semantics/openAccessArticulação temporomandibularDiagnósticoImagem por ressonância magnéticaOrtodontiaAvaliação por RM das ATMs em crianças e adolescentes com má-oclusão de classe III e/ou subdivisão de angleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisreponame:Repositório Comum do Brasil - Depositainstname:Instituto Brasileiro de Informação em Ciência e Tecnologia (Ibict)instacron:IBICTTEXTDissertação Daniella Torres Tagawa 06.01.2020.pdf.txtWritten by FormatFilter org.dspace.app.mediafilter.TikaTextExtractionFilter on 2025-06-06T20:16:30Z (GMT).Extracted texttext/plain102959https://deposita.ibict.br/bitstreams/dc0c9c5c-fe16-4b3b-9166-ee50a6cc05cc/downloade358ac74f1bd3145360759499bb5cb60MD53falseAnonymousREADTHUMBNAILDissertação Daniella Torres Tagawa 06.01.2020.pdf.jpgWritten by FormatFilter org.dspace.app.mediafilter.PDFBoxThumbnail on 2025-06-06T20:16:30Z (GMT).Generated Thumbnailimage/jpeg2718https://deposita.ibict.br/bitstreams/ed318582-ff0b-48e1-af4d-62babb23ebb6/download87400cc2298004ac9d444ca35121e56fMD54falseAnonymousREADLICENSElicense.txtWritten by org.dspace.content.LicenseUtilstext/plain;
