Abstract: The aim of this study was to evaluate temporomandibular joint radiographs of children in primary dentition, obtained by conventional transcranial radiography, indirect digitization, digitized images using 3D and brightness/contrast tools. Condyle position was also determined measuring anterior, superior and posterior joint space. The X-Ray machine GE-1000 and the head positioner Accurad 200 were used. Radiographs were digitized using a scanner with transparency and registered in Adobe Photoshop 5.0. Images were evaluated by four examiners as follows: 0--unacceptably quality; 1--poorly diagnostic quality; 2--optimal visualization quality. Articular space was measured using a digital caliper. A significant difference (Sign Test) was found between conventional radiography and the remaining modalities (Conventional/Unenhanced p<0.001; Conventional/3D p<0.001; Conventional/Brightness and Contrast p=0.017). The mean distance of anterior, superior and posterior regions was 2.2(0.5), 3.5(0.9) and 3.9(1.2) mm, respectively. Conventional and brightness/contrast digitized radiographs showed higher diagnostic quality. The posterior joint space was larger than the anterior one, demonstrating anterior condylar position.
