“…4 Available literature on CBCT has become extensive since then, including reviews for application to the TMJ. [5][6][7][8] The present overview will give an update on TMJ imaging using CBCT and its diagnostic value compared with other imaging modalities, with main sections on diagnostic accuracy and OA. The usefulness of CBCT in the diagnostic assessment of other TMJ conditions will be shortly reviewed.…”

The present review will give an update on temporomandibular joint (TMJ) imaging using CBCT. It will focus on diagnostic accuracy and the value of CBCT compared with other imaging modalities for the evaluation of TMJs in different categories of patients; osteoarthritis (OA), juvenile OA, rheumatoid arthritis and related joint diseases, juvenile idiopathic arthritis and other intra-articular conditions. Finally, sections on other aspects of CBCT research related to the TMJ, clinical decision-making and concluding remarks are added. CBCT has emerged as a cost-and dose-effective imaging modality for the diagnostic assessment of a variety of TMJ conditions. The imaging modality has been found to be superior to conventional radiographical examinations as well as MRI in assessment of the TMJ. However, it should be emphasized that the diagnostic information obtained is limited to the morphology of the osseous joint components, cortical bone integrity and subcortical bone destruction/production. For evaluation of soft-tissue abnormalities, MRI is mandatory. There is an obvious need for research on the impact of CBCT examinations on patient outcome.

“…An etiologic complex of factors such as trauma, emotional stress, muscular hyperactivity, and inflammatory and degenerative diseases may compromise the equilibrium of the temporomandibular joint (TMJ), leading to the development of temporomandibular disorder (TMD) 1 . The symptoms of TMD include decreased jaw mobility, pain in masticatory muscles, TMJ pain, joint sounds, and restriction or deviation in mouth opening 2 ; however, pain is the main symptom of TMD and also the major reason for patients to seek treatment 3 .…”

ObjectiveTo assess the degenerative bone changes of the jaw head and the condylar mobility regarding gender and age. Methods The sample was composed of 106 CBCT images for TMJ region from patients over 18 years old, from both genders, from the archives of a radiological clinic in the city RESUMO ObjetivoAvaliar as alterações ósseas degenerativas na cabeça da mandíbula e a mobilidade condilar com relação ao gênero e à faixa etária. MétodosA amostra foi constituída por 106 exames de TCFC para a região de ATM de pacientes com mais de 18 anos, do arquivo de uma clínica de radiologia odontológica, localizada na cidade de Campina Grande, PB, Brasil. As imagens foram obtidas com os pacientes em máxima intercuspidação e abertura de boca. As imagens foram examinadas por um radiologista, por meio do próprio software do tomógrafo Xoran CAT ® , usando-se um monitor com alta resolução e máxima qualidade de cor (12 bits) em ambiente com luz reduzida. Foram avaliados os aspectos tomográficos das alterações ósseas degenerativas (facetamento, erosão, osteófitos, esclerose óssea e pseudocisto) de ambas as ATM. As associações entre as alterações degenerativas e o sexo e a faixa etária foram investigadas por meio dos testes exato de Fisher, G e Qui-quadrado. Os dados obtidos quanto à excursão condilar (normoexcursão, hipoexcursão e hiperexcursão), segundo a localização também foram submetidos a análises descritivas. ResultadosAs alterações mais frequentes foram o facetamento (58,5%), seguido de osteófito (44,3%), erosão (22,6%), esclerose (13,2%) e pseudocisto (10,4%). Em relação à excursão condilar, observou-se que a normoexcursão foi a mais prevalente (71,7%). ConclusãoAs alterações ósseas degenerativas ocorreram de forma mais frequente em mulheres e de forma bilateral, e houve um aumento da frequência com a idade. Não foi encontrada correlação entre a excursão condilar e a presença de alterações na ATM, sendo a normoexcursão mais frequente.Termos de indexação: Articulação temporomandibular.

“…Kretapirom et al 13) have indicated that magnetic resonance imaging (MRI) images of RA patients with TMJ involvement showed more frequent joint effusion and synovial proliferation than temporomandibular disorder (TMD) patients. In recent times, cone-beam CT (CBCT) has been used for assessment of TMJs because it is more economical and has a lower radiation exposure than conventional CT. 14) Other studies have proposed that CBCT images are superior to corrected angle linear tomography, panoramic projections 15) and MRI. 16) Despite the advantages of CBCT in diagnosing osseous change of TMJs, the study evaluating CBCT TMJ images of RA patients has not been performed yet.…”
