13. A 3-D evaluation of transverse dentoalveolar changes and maxillary first molar root length after rapid or slow maxillary expansion in children
RESUMO Objetivo: o objetivo do presente trabalho foi realizar um estudo clínico randomizado comparando os efeitos da expansão rápida da maxila (ERM) e da expansão lenta da maxila (ELM). O comprimento radicular do primeiro molar superior permanente e o deslocamento dentro do alvéolo foram estudados por meio de imagens de tomografia computadorizada de f

14. Analysis of maxillary sinus septa by cone-beam computed tomography
Resumo Introdução A pneumatização do seio maxilar pode impossibilitar a instalação direta de implantes na região posterior da maxila, e a solução nesses casos é submeter o paciente a uma cirurgia de levantamento do assoalho do seio maxilar. A complicação mais comum dessa cirurgia é a perfuração da membrana sinusal. Variações anatômicas no

15. Method to Determine the Root Canal Anatomic Dimension by using a New Cone-Beam Computed Tomography Software
Resumo Este estudo discute um método para determinar a dimensão anatômica do canal radicular usando o software e-Vol DX. A metodologia consiste em inicialmente estabelecer as posições corretas que serão medidas, definir o ponto na borda da estrutura anatômica e ajustar a posição intermediária na escala de cinza na imagem em tomografia computadoriza

16. Root perforations: a review of diagnosis, prognosis and materials
Abstract: Root perforation results in the communication between root canal walls and periodontal space (external tooth surface). It is commonly caused by an operative procedural accident or pathological alteration (such as extensive dental caries, and external or internal inflammatory root resorption). Different factors may predispose to this communication,

17. Volumetric reconstruction and determination of minimum crosssectional area of the pharynx in patients with cleft lip and palate: comparison between two different softwares
Abstract Objective: The aim of this study was to assess the accuracy of volumetric reconstruction of the pharynx by comparing the volume and minimum crosssectional area (mCSA) determined with open-source applications (ITK-Snap, www.itksnap.org ; SlicerCMF) and commercial software (Dolphin3D, 11.8, Dolphin Imaging & Management Solutions, Chatsworth, CA, USA)

18. Maxillary sinus floor pneumatization and alveolar ridge resorption after tooth loss: a cross-sectional study
Abstract This is a cross-sectional study that aimed to estimate maxillary sinus floor (MSF) pneumatization in single missing tooth of posterior maxilla, by using cone-beam computed tomography (CBCT). CBCT images were analyzed bilaterally and divided into 2 groups: edentulous site (EdS) - edentulous single region of upper second premolar, first or second mola

19. Relationship between mandibular symphysis dimensions and mandibular anterior alveolar bone thickness as assessed with cone-beam computed tomography
RESUMO Objetivo: o objetivo desse artigo foi avaliar a correlação entre as dimensões da sínfise e a espessura do osso alveolar (EOA) na região anterior da mandíbula. Métodos: imagens de tomografia computadorizada de feixe cônico (TCFC) de 51 pacientes foram selecionadas e medidas. As EOAs vestibular e lingual dos dentes anteroinferiores foram medi

20. 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

21. Effect of 1% sodium alendronate in the non-surgical treatment of periodontal intraosseous defects: a 6-month clinical trial
Abstract Background and objectives Few studies have evaluated the effect of the topical application of sodium alendronate (ALN) on the treatment of intrabuccal bone defects, especially those caused by periodontitis. This 6-month randomized placebo controlled clinical trial aimed at evaluating the effect of non-surgical periodontal treatment associated with

22. Evaluation of the rapid and slow maxillary expansion using cone-beam computed tomography: a randomized clinical trial
RESUMO OBJETIVO: o objetivo do presente ensaio clínico randomizado foi avaliar as transformações dentárias, dentoalveolares e ósseas que ocorrem imediatamente após o tratamento com expansão rápida da maxila (ERM) e lenta (ELM) usando expansores do tipo Haas. MÉTODOS: todos os indivíduos foram submetidos a tomografias computadorizadas de feixe c�

23. Diagnosis of alveolar and root fractures: an in vitro study comparing CBCT imaging with periapical radiographs
Abstract Objective To compare periapical radiograph (PR) and cone-beam computed tomography (CBCT) in the diagnosis of alveolar and root fractures. Material and Methods Sixty incisor teeth (20 higid and 40 with root fracture) from dogs were inserted in 60 anterior alveolar sockets (40 higid and 20 with alveolar fracture) of 15 macerated canine maxillae.
