ABSTRACT:This research aimed at assessing the relation between the horizontal condylar angle (HCA) and the internal derangement (ID) of the temporomandibular joint (TMJ), as a result of interference by the TMJ disk, in individuals undergoing magnetic resonance (MR) scans. The sample included a total of 144 TMJs (sagittal and coronal views) of 72 subjects, 15 of whom were male and 57 female, with ages ranging from 15 to 70. The scans were made in a Signa system (GE) model at a magnetic field magnitude of 1.5 T. Sixty-eight TMJs were found to be normal, while 46 showed anterior displacement with reduction. Of these, 41 had some kind of adaptive change in the condyle, while 5 showed degenerative changes. Anterior displacement without reduction was found in 29 joints, 12 of which showed adaptative changes in the condyle, while 17 showed degenerative changes. Only one posterior displacement of the articular disk was recorded. For the TMJs in which disk displacement was found, such values achieved 24.69º on the right side, and 22.94º on the left side. Hence, it was possible for us to conclude that the HCA tends to increase in those TMJs where ID is present. For contralateral TMJs, a strong association was observed between HCA values (57.8%), state of normality (69.7%), and ID (66.7%). To corroborate such findings, a correlation between contralateral HCA values (63.31%) and the diagnosis for contralateral TMJs (68.05%) was determined. Thus, we could infer that there is a tendency between contralateral TMJs to share characteristics and conditions. DESCRIPTORS: Temporomandibular joint; Nuclear magnetic resonance; Temporomandibular joint disk. RESUMO:Esta pesquisa teve por objetivo avaliar a relação entre o valor do ângulo horizontal do côndilo (AHC) e o desarranjo interno (DI), por interferência do disco da articulação temporomandibular (ATM), de indivíduos indicados para exame por ressonância magnética (RM). A amostra perfez um total de 144 ATMs (cortes sagital e coronal) de 72 indivíduos, na faixa etária de 15 a 70 anos, 15 do gênero masculino e 57 do gênero feminino. Os exames foram procedidos em um sistema modelo Signa (GE), magnitude de 1,5 T para o campo magnético. Sessenta e oito ATMs apresentaram uma condição de normalidade e 46 apresentaram deslocamento anterior do disco articular com redução. Dessas, 41 expressaram algum tipo de alteração adaptativa no côndilo e cinco, alterações degenerativas. Vinte e nove articulações mostraram deslocamento anterior do disco articular sem redução, sendo que 12 dessas apresentaram alterações adaptativas do côndilo e 17, alterações degenerativas. Foi registrado apenas um caso de deslocamento posterior do disco articular. O valor médio encontrado para o AHC do lado direito foi de 22,09º e para o lado esquerdo foi de 21,47º, para aquelas ATMs que se apresentaram em condições de normalidade. Para as ATMs com deslocamento de disco, esses valores foram de 24,69º para o lado direito e 22,94º para o lado esquerdo. Desse modo, foi-nos possível concluir que existe uma tendência ao aumen...

A aplicação da informática à Odontologia tem máxima importância na Radiologia, notadamente na obtenção e formação de imagens digitais ou digitalizadas. Estas, dada a possibilidade de manipulação, ficam sujeitas a riscos quanto à ilicitude dos procedimentos intentados e de seus fins. Impõe-se, portanto, a necessidade imediata de edição de legislação específica que assegure a manipulação eletrônica de imagens, respeitando-se seus limites e aplicações, em benefício da Justiça e da sociedade.

This research aimed to determine the comparison, correlation and accuracy of three radiographic methods and one clinical method for measuring the distance between cemento-enamel junction and the alveolar crest in lower molars and bicuspids in patients with periodontal bone loss, who underwent clinical probing and vertical bite-wing radiographs. Only areas with probing depth greater or equal to 5 mm were included in the sample. The distance between cemento-enamel junction and the apical portion of 82-bone defect was verified through double-needle compass, digital caliper and the software Dentscan Dentview. The accuracy, correlation and comparison between clinical and radiological variables were recorded. The results showed that when the attachment level was the gold standard, the double-needle compass expressed the best accuracy (71% of sensitivity and 84.5% of specificity), followed by digital caliper (0% of sensitivity and 82.8% of specificity) and Dentscan Dentview (0% of sensitivity and 75.9% of specificity) regardless of testing variable or gold standard’s location, more severe diseases were underestimated than overestimation of onset disease. The systems with digital resources showed greater measurement values than methods without digital resources. All the variables presented.
