13. CONE BEAM COMPUTED TOMOGRAPHY IN VETERINARY DENTISTRY: DESCRIPTION AND STANDARTIZATION OF THE TECHNIQUE / Tomografia computadorizada de feixe cônico na odontologia de cães e gatos
A tomografia computadorizada é uma modalidade de diagnóstico utilizada na odontologia desde a década de 90, que apresenta uma série de vantagens sobre outros exames de imagem, como menor exposição à radiação ionizante, menor tempo na aquisição das imagens, dispensa do processamento químico e menor custo. O exame tomográfico de feixe cônico é e

14. Assessment of proximal caries lesions through microtomography, cone beam CT and digital radiographs / Avaliação de cáries proximais por meio da microtomografia, tomografia Cone Beam e radiografias digitais
Dental caries is still a great challenge to dentists, manly in proximal surfaces due to its difficult diagnosis. Many types of equipment have been designed to minimize this problem, specially aiming early caries detection. Among all, one of the most used by clinicians is the interproximal radiograph. The International Caries Assessment System (ICDAS) is a cl

15. Estudo radiográfico e por tomografia computadorizada das formações orais em cães / Radiographic and computed tomographic studies of oral tumors in dogs
The oral cancers represent the fourth most common cancer in dogs. Imaging of oral cancer is needed to determine the tumor extension and the affected local tissues, assisting in prognosis and surgical planning. Currently the radiographic examination is the most used diagnostic method. It is accessible and less expensive, but the large number of structures in

16. Determinação do trajeto do canal mandibular por meio de tomografia computadorizada em mandíbulas de cadáveres de Canis familiaris braquicefálicos e mesatecefálicos / Determination of the mandibular canal course by means of computerized tomography in mandibles of brachycephalic and mesaticephalic Canis familiaris
Sabe-se que para determinados procedimentos cirúrgicos em Odontologia, como a exodontia, a cirurgia ortognática, cirurgia ortopédica, cirurgia de neoplasias e a colocação de implantes dentários, é importante conhecer a localização exata do trajeto do canal mandibular (CM) que contém o feixe vasculonervoso. O objetivo desta pesquisa foi determinar p

17. Comparative study of single and multislice computed tomography for assessment of the mandibular canal
OBJECTIVE: The purpose of this study was to evaluate the accuracy of relative measurements from the roof of the mandibular canal to the alveolar crest in multislice (multidetector) computed tomography (MDCT) and single-slice computed tomography (SSCT). MATERIAL AND METHODS: The sample consisted of 26 printed CT films (7 SSCT and 19 MDCT) from the files of th

18. Análise comparativa ex vivo dos efeitos do preparo de canais curvos com diferentes sistemas rotatórios, por meio de tomografia computadorizada helicoidal / Ex vivo comparative analysis of the effects of root canal preparation with different rotary systems by helicoidal computerized tomography
The aim of this study was to compare the time of preparation, canal transportation, direction of transportation, mean centering ratio, and the percentage of area increase of canals instrumented using three rotary systems, assessed by spiral computed tomography. Forty lower molars with completely formed apices, curvature angle = 20, and radius of curvature <1

19. "Correlação entre os aspectos clínicos e a tomografia computadorizada na avaliação da destruição óssea provocada por neoplasias malignas de boca e orofaringe" / Clinical and computed tomography correlation in the assessment of bone invasion in oral and oropharynx malignant neoplasms
The assessment of bone destruction by oral and oropharynx malignant neoplasms is a critical factor in the therapeutic planning and to determine the patient prognostic. The aim of this study was to determine the clinical aspects (localization, clinical manifestation and stage) that can be associated with the potential of bone infiltration, and also determine

20. Avaliação da localização do canal mandibular por meios de exames tomografico (linear, Pluridirecional e computadorizados de alta resolução) em comparação com a anatomia ossea topografica
The aim of this study was compare the vertical and horizontal dimensions in images obtained from dried skulls by means of three types of tomographic exams: linear; transversal pleuridirectional panoramic and computerized high resolution with bone topographic anatomy. The selection of a precise radiographic method proved to be of great importance in the plann
