1. Diagnostic Performance of Digital Radiograph and Low-Dose Computed Tomography for the Diagnosis of Fishbone Retention in the Oropharynx
Abstract Introduction Fishbone foreign body retention is one of the most common problem with various clinical manifestations from asymptomatic, abscess formation, and perforation to mediastinitis with subsequence morbidity and mortality. Accurately identifying the location of the fishbone leads to precise removal, which, in turn, prevents serious consequenc

4. Clinical and radiographic evaluation of Bio-Gen with biocollagen compared with Bio-Gen with connective tissue in the treatment of class II furcation defects: a randomized clinical trial
OBJECTIVE: Treatment of furcation defects are thought to be challenging. The purpose of this study was to evaluate the clinical and radiographic parameters of Bio-Gen with Biocollagen compared with Bio-Gen with connective tissue in the treatment of Class II furcation defects. MATERIAL AND METHODS: In this clinical trial, 24 patients with Class II furca

5. Desenvolvimento de um Sistema de Auxílio ao Diagnóstico de Pneumonia na Infância Utilizando Visão Computacional / Development of a System of Aid to the Diagnosis of Pneumonia in Children Using Computer Vision
This work aims to develop a system to aid in the diagnosis of pneumonia by computer, termed pneumocad, which aims to identify chest radiographies compatible with the disease. Techniques were used for the recognition of patterns in textures through the decomposition of the wavelet transforms of the features extracted from the decomposition and classification

6. Nível ósseo marginal em população de idosos institucionalizados / Marginal bone level in institutionalized elderly population
O aumento da longevidade da população mundial faz com que a expectativa de manutenção da dentição possa ser observada em idosos. Esse fato pode acarretar em aumento da prevalência das doenças periodontais nessa população. O objetivo desse estudo foi avaliar a condição periodontal de idosos institucionalizados. Foram utilizados dados secundários

7. Contribuição da imagem tridimensional para o diagnóstico do cisto de retenção mucoso do seio maxilar / Three-dimensional Image Contributing to the diagnosis of Mucous Retention cyst in Maxillary Sinus
Objective: To detect the mucous retention cyst of maxillary sinus (MRCMS) through panoramic radiography and cone beam computed tomography (CBCT). Methods: Six thousand panoramic radiographs were selected from digital database for diagnostic analysis of MRCMS. We detected suggestive images of MRCMS in 185 radiographs of patients who were located and invited t

9. Clinical and radiographic study of the morphology of the stylohyoid complex in patients with Temporomandibular Disorders and Orofacial Pain. / Estudo clínico e radiográfico dos aspectos morfológicos da cadeia estilo-hióidea em sujeitos com disfunção temporomandibular e dor orofacial
The relationship between temporomandibular disorders and Eagle\ s syndrome occurs due to the similarity of symptoms. The knowledge gained about the Eagle\ s syndrome shows that its symptoms can be very easily confused with other types of craniomandibular disorders and numerous other diseases found in regions of the skull, face and neck. The lack of informati

10. Radiographic image analysis of apicetomized roots irradiated with Nd:YAG laser using imaging processing of direct digital radiographs / Análise da imagem radiográfica de raízes apicetomizadas e irradiadas com laser de Nd:YAG por meio do processamento de imagem de radiografias digitais diretas
In this research, we carried out an evaluation of the digital radiographic image of dental root-ends irradiated with Neodymium Yttrium Aluminum Garnet (Nd:YAG) laser after apical resection. With the intention of founding alterations in the digital radiographic image of the roots caused by laser irradiation, we developed an in vitro experimental model. We mad

11. Avaliação in vivo da densidade óssea ao redor de implantes osteointegráveis com diferentes plataformas / In vivo assessment of bone density around dental implants with different platforms
In regard of the high successful rates and the excellent outcome, dental implants become the first option in rehabilitation for dental loss. In this way the maintenance of soft peri-implant tissues came up as a new issue to consider especially when esthetic areas are being restored. Generally a bone loss of approximately 1,5 mm occurs after one year of denta

12. 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
