1. The Relationship between an Accessory Maxillary Ostium and Variations in Structures Adjacent to the Maxillary Sinus without Polyps
Abstract Introduction The maxillary sinus and its variations are very important to dentistry and rhinology. Objective To investigate the effect of the accessory maxillary ostium (AMO) on the variations of adjacent structures of the maxillary sinus. Methods The computed tomography (CT) images of 400 patients were retrospectively evaluated. The prevalence o

2. Use of Micro-Computed Tomography for Bone Evaluation in Dentistry
Resumo A microtomografia computadorizada segue o mesmo princípio da tomografia computadorizada utilizada para avaliação dos pacientes, mas neste caso, é empregada para pequenas amostras com alta resolução. De forma não destrutiva, as amostras podem ser escaneadas, e cada fatia obtida é organizada de forma seriada para formar um volume tridimensional

3. Root and canal symmetry in the mandibular anterior teeth of patients attending a dental clinic: CBCT study
The aims of this study were to evaluate the number of roots/root canals in the mandibular anterior teeth of a Turkish population, to assess the relationship between gender or age and the frequency of two canals in a single root, and to determine the symmetry in root/root canal numbers between contralateral sides among patients. Cone-beam computed tomography

4. Evaluation of the posterior superior alveolar artery and the maxillary sinus with CBCT
Assessment of the maxillary sinus anatomy before sinus augmentation is important for avoiding surgical complications, because of the close anatomical relationship between the posterior maxillary teeth and the maxillary sinus. The posterior superior alveolar artery (PSAA) is the branch of the maxillary artery that supplies the lateral sinus wall and overlying

5. Estudo da identificação humana por meio da imaginologia dos seios frontais.
The aim of this study was to verify the applicability of parameters for human identification using the frontal sinuses, used by Tatlisumak et al. (2007), using axial and coronal reconstructions of CBCT and extraoral radiographs. From 58 dry disjointed skulls existing in the Management of Legal Medicine of Paraiba (PB-GEMOL) and University Center of Joao Pess

6. Avaliação dos componentes anatômicos do sistema estomatognático de crianças com bruxismo, por meio de imagens obtidas por tomografia computadorizada cone beam / Evaluation of the anatomical structures of the stomatognathic system in children with bruxism by cone beam computed tomography
Among the parafunctional activities of masticatory system, bruxism can be higlighted. It occurs during sleep (Sleep Bruxism - SB) or wakefulness (Awake Bruxism - DB), which occur in two different states of consciousness (sleep and wakefulness). The International Classification of Sleep Disorders defines bruxism as \"a movement disorder with a stereotyped pat

7. Long axis and tipping evaluation of mandible and maxilla anterior teeth by cone beam tomography in patients with unilateral cleft lip and palate / Avaliação da angulação e inclinação dos dentes anteriores por meio de tomografia computadorizada por feixe cônico, em pacientes com fissura transforame incisivo unilateral
Recent developments on the field of imaginology allowed computed tomography to become largely used in dentistry. Details of anatomic structures can be visualized with high quality images and measurements can be taken on several plans helping all professionals involved on the treatment of patients with alveolar bone defect, malocclusion and facial deformities

9. 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

10. Tomographic analysis of the apical third of curved canals after endodontic treatment with different automated systems / Análise tomográfica do terço apical de canais curvos após preparo endodôntico com diferentes sistemas automatizados
This study aimed to evaluate through Beam Computed Tomography Volumetric cone (Cone-Beam), transport and the ability to centralize various automated systems. The mesiobuccal roots of maxillary first molars were divided into four groups (n=10) according to the automated systems used: GI - reciprocating with K-file Flexofile, GII - reciprocating with file NiTi

12. 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
