4. Galea and periosteum flap filled with bone fragments in rabbits
PURPOSE: To study the bone viability of a vascularized galea and periosteum flap filled with bone fragments, as a substitute of the bone graft in facial reconstructive surgery. METHODS: Forty rabbits were studied, and divided in two groups. One had a simple galea and periosteum flap done and the other had the same flap done and filled with bone fragments of

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. Vibroacustografia na avaliação tridimensional de artroplastia total de quadril / Vibro-acoustography in the tridimensional evaluation of total hip arthroplasty
Vibro-acoustography (VA) is a high lateral resolution (<0.7 mm), speckle-free, non- ionizing and non-invasive image based on the nonlinear combination phenomenon of ultrasound waves (MHz) that generates a narrow focus region of low frequency (kHz). In this work, we propose a VA-based tridimensional evaluation of the exposed area of implants, after total hip

7. A comparative assessment of the WALA ridge in dissected mandibles and cast models as well as its measurement in occlusal radiographies and tomographies / Avaliação comparativa da Borda WALA em mandíbulas secas e modelos e da sua mensuração em radiografias oclusais e tomografias
Introdução: a determinação da Borda WALA em modelos de gesso permitia defini-la como uma linha imaginária utilizada no planejamento, seguimento e finalização de casos clínicos. Procurou-se determinar a Borda WALA em modelos de gesso de pacientes ortodônticos, mandíbulas secas, radiografias oclusais e cortes tomográficos dos pacientes e mandíbulas

8. Comparison between the digital radiographies through the conventional radiography of periodontal bone reabsorptions / Comparação entre as imagens radiográficas digital com a convencional das reabsorções ósseas periodontais
Comparing the periodontal bone defects, through data obtained with radiographies by the parallelism periapical te chnic, using the conventional and digital images. To obtain the images a x-ray device of the brand Dabi Atlante was used, where the radiographic exam was standardized to obtain a digital and conventional image with the best in detai l and the lea

10. Influência da associação da sinvastatina à matriz de osso desmineralizado bovino na reparação de defeitos ósseos em calvária de ratos
Bone defect healing is a constant concern to several areas of Dentistry. A great variety of materials is currently used to help in the healing process as well as to speed it up. Materials such as autografts, xenografts, membranes, some drugs, and the association of some of them are being used. Simvastatin, a substance used to reduce cholesterol levels, has s

11. Alterações dimensionais mandibulares e sua relação com atividade muscular em pacientes portadores de próteses implantossuportadas / Mandibular dimensional changes and its relationship with muscular activity in pacients when implant-supported prosthesis are used
Purpose: The purpose of the present study was to evaluate the correlation between masseter muscle activity and changes occurred in mandibular bone height, posterior to the last implant, one year after implant-supported prosthesis rehabilitation in repared cleft lip and palate patients. Materials and Methods: changes in mandibular bone height were measured in

12. 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
