2. Evaluation of bulk-fill systems: microtensile bond strength and non-destructive imaging of marginal adaptation
Abstract The objective of this study was to investigate microtensile bond strength (MTBS) and interfacial adaptation (IA) of bulk-fill restorative systems bonded to dentin in Class-I-preparations. Box-shaped preparations (4-mm-long, 3-mm-wide, 2-mm-high) made in extracted molars, and Teflon matrix with the same dimensions positioned over the occlusal surface

3. PENETRAÇÃO E DISTRIBUIÇÃO DO CONSOLIDANTE PARALOID® B-72 EM CERÂMICA BRANCA ESTUDADA POR TOMOGRAFIA COM NÊUTRONS
The neutron tomography technique was employed to study the penetration and distribution of the consolidant Paraloid® B-72 in ceramic. This study was carried out in white contemporary ceramic vessels which were maintained in two distinct and controlled air humidity conditions, 35% and 90%, before the consolidant application (brushing technique). The results

4. Effect of Dental Restorative Material Type and Shade on Characteristics of Two-Layer Dental Composite Systems
Abstract The purpose of this study was to investigate the effects of shade and material type and shape in dental polymer composites on the hardness and shrinkage stress of bulk and two-layered restoration systems. For this purpose, some bulk and layered specimens from three different shades of dental materials were prepared and light-cured. The experiments w

5. Effects of modeling liquid/resin and polishing on the color change of resin composite
Abstract Modeling liquids/resins have been used to build up resin composite (RC) restorations, although there is a lack of information regarding their effects on the color stability of the latter. Therefore, the purpose of the present study was to evaluate the effects of the presence of modeling liquid between layers of RC and the finishing/polishing state o

6. Implementação paralela do algoritmo iterativo de busca do parâmetro de regularização ótimo para o funcional de Tikhonov no problema de restauração de imagens / Parallel implementation of the iterative algorithm to search the optimal regularization parameter for the Tikhonov functional problem in image restoration
The use of techniques with the functional of Tikhonov in image processing has been widely used in recent years. The basic idea in this process is to modify an initial image using a convolution equation and to find a parameter which minimizes the function in order to obtain an aproximation of the original image. However, a typical problem in this method consi

7. Inflammatory root resorption in primary molars: prevalence and associated factors
This study aimed at determining the prevalence of inflammatory root resorption and associated factors in 1068 primary mandibular molars in 453 children 3 to 12 years of age. Age, dental history and medical history were recorded using a questionnaire administered to the children's parents/caregivers. Previously trained and calibrated examiners assessed radiog

8. Análise fotoelástica da tensão de contração da polimerização de compósitos resinosos sob influência de técnicas restauradoras / Photoelastic analysis of polymerization shrinkage stress of composites under the influence of restorative techniques
Polymerization shrinkage stress is an undesirable and inevitable characteristic of adhesive restorations. It is important to understand the stress distribution to improve the clinical effectiveness of resin composite restoration. Chapter 1: The aim was to evaluate the polymerization shrinkage stress and degree of conversion of a resin composite material subm

9. Retratamento endodôntico: casuística e comparação de dois métodos de diagnóstico por imagem / Endodontic retreatment: case studies and comparison of two methods of diagnosis by image
The radiographic test is an essential diagnosis component in the treatment of problems of endodontic origin. Despite the technical and scientific developments in endodontics, the number of endodontic retreatment continues high. In this scenario, Computerized Beam Cone Tomography (CBCT) is used to obtain three-dimensional images without distortions of structu

10. Mimetic finite difference methods in image processing
We introduce the use of mimetic methods to the imaging community, for the solution of the initial-value problems ubiquitous in the machine vision and image processing and analysis fields. PDE-based image processing and analysis techniques comprise a host of applications such as noise removal and restoration, deblurring and enhancement, segmentation, edge det

11. A assessoria jurídica universitária em direitos de gênero como uma estética da amizade
This study examines the practices in university legal counsel, questioning the experience of Generalizing Group-G8 (G8-G) workers of the Office of Legal Counsel of Rio Grande do Sul Federal University (UFRGS-SAJU) working with gender rights. The study investigates how the practice of university legal counsel arises as an ethic that enhances the production of

12. Influence of dental metallic artifact from multislice CT in the assessment of simulated mandibular lesions
OBJECTIVE: This study evaluated the influence of metallic dental artifacts on the accuracy of simulated mandibular lesion detection by using multislice technology. MATERIAL AND METHODS: Fifteen macerated mandibles were used. Perforations were done simulating bone lesions and the mandibles were subjected to axial 16 rows multislice CT images using 0.5 mm of s
