1. Comparative study between Cone-Beam volumetric tomography and periapical radiographs on helping Endodontic diagnosis / ESTUDO COMPARATIVO ENTRE A TOMOGRAFIA VOLUMÉTRICA CONE-BEAM E RADIOGRAFIAS PERIAPICAIS NO AUXÍLIO AO DIAGNÓSTICO ENDODÔNTICO
This study aimed to analyze and compare volumetric tomography Cone- Beam and periapical examination, by technique of Clark, identifying accidents and endodontic complications, which were simulated, for endodontic interest. Sixteen human teeth from three human jaws were submitted to preparation of 20 changes/injuries in order to simulate situations that can l

6. Avaliação comparativa dos coeficientes de Hounsfield entre a tomografia computadorizada de feixe cônico e tomografia multislice / Comparative evaluation of the coefficients of Hounsfield between cone computed tomography and multislice CT
The aim of this study was to compare the attenuation coefficients (Hounsfield Unit) in both cone-beam computed tomography (CT) and multislice CT images. The 40-channel CT scanner (SOMATOM Sensation 40 - Siemens) was used to obtain images (n=20) of macerated mandibles considering the following protocol: axial slices of 0.7 mm in thickness and an interval of 0

7. Age estimation by pulp/tooth area ratio in anterior teeth using cone-beam computed tomography: comparison of four teeth
Abstract Objectives Age estimation is one of the most important factors in forensic medicine. Measuring secondary dentin deposition using cone-beam computed tomography images is an easy and noninvasive method. The aim of this study was to evaluate cone-beam computed tomography images as a reliable method to estimate chronological age by pulp/teeth ratio in

9. Cone-beam tomography assessment of condylar position discrepancy between centric relation and maximal intercuspation
The magnitude of occasional discrepancies between the centric relation and maximal intercuspation positions remains a controversial subject. This study quantitatively evaluated the possible discrepancies in the condyle/mandibular fossa relationship between these positions using cone-beam computed tomography. Twenty young and asymptomatic volunteers were dist

10. Tomografia computadorizada de feixe cônico na odontologia de cães e gatos / CONE BEAM COMPUTED TOMOGRAPHY IN VETERINARY DENTISTRY: DESCRIPTION AND STANDARTIZATION OF THE TECHNIQUE
Eleven dogs and four cats with buccodental alterations, treated in the Centro Veterinário do Gama, in Brasilia, DF, Brazil, were submitted to cone beam computed tomography. The exams were carried out in a i-CAT tomograph, using for the images acquisition six centimeters height, 40 seconds time, 0,2 voxel, 120 kilovolts (kV) and 46,72 milliampéres per secon

12. Comparative analysis between mandibular positions in centric relation and maximum intercuspation by cone beam computed tomography (CONE-BEAM)
This research consisted of a quantitative assessment, and aimed to measure the possible discrepancies between the maxillomandibular positions for centric relation (CR) and maximum intercuspation (MI), using computed tomography volumetric cone beam (cone beam method). The sample of the study consisted of 10 asymptomatic young adult patients divided into two t
