1. O que o dentista deve considerar ao indicar o diagnóstico por imagem em pacientes pediátricos?
O dentista ao indicar um exame de imagem odontológica para auxiliar em seu diagnóstico e ou plano de tratamento, deve selecionar o tipo de exame de acordo com as necessidades individuais do paciente e não como rotina
. A necessidade e os tipos de exames a serem realizados devem ser personalizados para cada paciente e com base na necessidade indiv

2. Potential of a New Cone-Beam CT Software for Blooming Artifact Reduction
Resumo Este estudo avaliou as dimensões de pinos intrarradiculares usando um novo software de tomografia computadorizada de feixe cônico (TCFC) e um micrômetro digital, e verificou o potencial da redução do artefato de contraste do branco. Sessenta e três dentes humanos unirradiculares foram modelados, obturados, preparados para colocação de pinos e

3. Accuracy of linear measurements performed with two imaging software in cone-beam computed tomography scans of dry human mandibles
ABSTRACT The present study aimed to assess the accuracy of linear measurements performed with two software packages in multislice (MSCT) and cone beam (CBCT) computed tomography (CT) images. The sample consisted of 10 human mandibles marked standardly 8 times with metallic orthodontic wires. The mandibles underwent both MSCT and CBCT scanning and were measur

4. Differential diagnosis and clinical management of periapical radiopaque/hyperdense jaw lesions
Abstract Great attention has been given to the study of radiolucent periapical lesions to avert possible misdiagnosis of apical periodontitis associated with certain radiolucent non-endodontic lesions. However, there are a significant number of radiopaque lesions found in the periapical region, which could be equally relevant to endodontic practice. The diag

5. Prediction of rapid maxillary expansion by assessing the maturation of the midpalatal suture on cone beam CT
RESUMO A expansão rápida da maxila (ERM) essencialmente consiste na abertura mecânica da sutura palatina mediana tanto nos ossos maxilares quanto nos ossos palatinos. A fusão da sutura palatina mediana determina o insucesso da ERM, um evento comum na adolescência tardia e fase adulta jovem. Recentemente, propôs-se a avaliação da maturação da sutura

6. Prevalence and morphometric analysis of three-rooted mandibular first molars in a Brazilian subpopulation
ABSTRACT The knowledge of the internal anatomy of three-rooted mandibular molars may help clinicians to diagnose and plan the root canal treatment in order to provide adequate therapy when this variation is present. Objectives: To determine the prevalence of three-rooted mandibular molars in a Brazilian population using cone beam computed tomography (CBCT)

7. The use of a biocompatible cement in endodontic surgery. A randomized clinical trial 1
ABSTRACT PURPOSE: To evaluate the clinical applicability of Pozzolana Biologic Silva cement (PBS(r)) in endodontic surgery. METHODS: Persistent apical periodontitis was diagnosed in 30 teeth of 12 patients by cone-beam computed tomography (CT). All patients had 2 or 4 affected teeth and underwent endodontic surgery with root-end filling. Patients with 2

8. Canal transportation and centering ability of curved root canals prepared using rotary and reciprocating systems
Abstract Aim: To evaluate canal transportation and centering ability of Protaper and WaveOne systems in curved root canals by cone-beam computed tomography. Methods: Twenty human molars were randomly divided into two groups according to the system used: Group GP (ProTaper Universal(r)) and group GW (WaveOne(tm)). CT scans were performed before and after th

9. Portland cement versus MTA as a root-end filling material. A pilot study
PURPOSE: To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material. METHODS: Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling. Patient A was treated wi

10. CT study of the performance of reciprocating and oscillatory motions in flattened root canal areas
Root canal preparation is an important step in endodontic treatment. The anatomical complexity of the middle third of the root compromises the effective cleaning of this area. Thus, advances have been made in instrumentation techniques and instruments for this purpose. The aim of this study was to evaluate the effects of three different instrumentation syste

11. Evaluation of technical quality and periapical health of root-filled teeth by using cone-beam CT
Objective This study aimed to assess the quality of root fillings, coronal restorations, complications of all root-filled teeth and their association with apical periodontitis (AP) detected by cone-beam computed tomography (CBCT) images from an adult Turkish subpopulation. Material and Methods The sample for this study consisted of 242 patients (aging f

12. Avaliação volumétrica da fenda alveolar por meio de tomografia computadorizada por feixe cônico (TCFC) em pacientes com fissura labiopalatina / Volumetric assessement of the alveolar cleft using Cone Beam Computerized Tomography (CBCT) in patients with cleft lip and palate
A reabilitação dos pacientes com fissura de lábio e palato teve significativa evolução nas últimas décadas, sendo o desenvolvimento do enxerto ósseo alveolar muito importante para este avanço. É um procedimento que requer atenção rigorosa aos detalhes, por esta razão os exames de imagem são de grande auxílio. As Tomografias Computadorizadas en
