28. Estudo comparativo de cefalogramas realizados sobre reconstruções de tomografia cone beam total e unilaterais da face e telerradiografias convencionais
A possibilidade de exploração das imagens oferecida pela tomografia computadorizada cone beam (TCCB) permite investigações mais detalhadas do paciente. Este estudo, empregando alguns destes recursos, se propôs a comparar medidas cefalométricas realizadas sobre telerradiografias convencionais e reconstruções de perfil total e unilaterais obtidas da TC

29. Cefalostato virtual-posicionamento inicial para a padronização na marcação de pontos craniométricos em imagens obtidas por tomografia computadorizada, para uso em cefalometria / The Virtual Cephalostat - the preliminar adjustment for standardization of skull orientation in landmarks localization using CT in cephalometric analyses
Objective: The development of new technology in dental diagnosis by cone beam CT (CBCT) image, made possible and accessible the realization of cephalometric evaluation through volumetric reconstructions of the skull. Scientific parameters with evidence-based are needed to implement its use. Some parameters used in conventional cephalometry (2D) maybe need to

30. Estudo comparativo do padrão cefalométrico dos jovens mestiços nipo-brasileiros - grandezas tegumentares e esqueléticas / Comparative study of the cephalometric norms for Japanese Japanese-Brazilian descents skeletal and soft tissue measurements
Introduction: Remaining the diverse population in Brazil, the different ethnic groups can present unique skeletal and soft tissue measurements. Studies must be established to support orthodontics diagnostic and treatment plans between different races and different standards. Objective: Obtain mean normal values to soft tissue and skeletal cephalometric varia

31. Evaluation of influence of DICOM and JPEG formats in the reproducibility of cephalometric landmarks in digital Frontal Teleradiographies / Avaliação da influência dos formatos DICOM e JPEG na reprodutibilidade de pontos cefalométricos em Telerradiografia digital em Norma Frontal
The digital image on DICOM format request a large store size capability, making difficult the transmission through internet, usually requesting the image compression via JPEG file format. The aim of this study was to evaluate the influence of DICOM and JPEG file formats on Quality Factors 100, 80 and 60, in the reproducibility intra and interexaminer at ceph
