1. Chemical and structural composition of black pigmented supragingival biofilm of bovines with periodontitis
RESUMO: A periodontite bovina é uma infecção multifatorial associada primariamente à microbiota potencialmente patogênica presente no biofilme bucal. Biofilmes são estruturas organizadas, nas quais os constituintes convivem em simbiose, descritos em outras espécies como um fator predisponente à periodontite. O objetivo do presente estudo foi caracter

2. Clinical performance and failure modes of pulpless teeth restored with posts: a systematic review
Abstract The aim of this systematic review was to compare the clinical performance and failure modes of teeth restored with intra-radicular retainers. A search was performed on PubMed/Medline, Central and ClinicalTrials databases for randomized clinical trials comparing clinical behavior and failures of at least two types of retainers. From 341 detected pape

3. Characterization of Fibers from Pineapple's Crown, Rice Husks and Cotton Textile Residues
Fibers from pineapple's crown (PCF), rice husks (RH) and cotton textile residues (RTF) were characterized by SEM, X-ray diffraction, FTIR and thermogravimetric analysis. Moisture content, water absorption, density and the distribution of the diameter of the fibers were also evaluated. RTF showed cylindrical microstructure with smooth surface, PCF showed cell

4. Floristic composition and spatial distribution of vascular epiphytes in the restingas of Maracanã, Brazil
Vascular epiphytes constitute a life form that is important to maintaining the biological diversity of forest ecosystems, because they provide food resources and specialized microenvironments for fauna in the forest canopy. This study aimed to describe the floristic composition and ecological aspects of vascular epiphytes occurring in the restingas (coastal

5. Influência do tipo de reconstrução coronoradicular e remanescente dentário no comportamento biomecânico de incisivos tratados endodonticamente
O objetivo deste estudo foi avaliar a influência do tipo de coroa, retentor e a quantidade de remanescente coronário na distribuição de tensões, deformação, resistência à fratura e padrão de fratura de incisivos centrais tratados endodonticamente. Para geração do modelo 3D foi selecionado incisivo central superior hígido. A geometria do esmalte

6. As fachadas da casa moderna
The object of this dissertation is the systematic study of the façades of modern singlefamily houses in the period 1915-60, which aim is to broaden and improve the typification criteria that are currently available. One of those criteria is the systematisation presented by architect Rodrigo Pérez de Arce in the essay As faces do moderno [The faces of the m

7. Resistência de união de materiais resinosos de baixa viscosidade em lesões incipientes de cárie em esmalte / Bond strength of experimental low viscosity resin materials in initial enamel caries
Infiltration of enamel-like initial caries lesions with low viscosity resins (infiltrants) seems to be a promising approach in dentistry and it have showed advantages regarding to remineralization or invasive treatments. In this way, material must penetrate and seal lesions intake, reinforcing carious structure and eventually avoiding lesion progression, wit

8. Efeito da clorexidina e flúor na resistência coesiva da estrutura dental irradiada e não irradiada
Radiation therapy significantly reduces the resistance of the tooth structure and the damage is potentially higher in the organic matrix. The use of products that promote the stabilization of collagen and / or agents to intensify the cross-links may provide less damage to the resistance of teeth irradiated. This study aimed analyze the effect of the use of c

9. Estrutura e espacialidade na obra de Mies van der Rohe
O presente trabalho trata da análise da estrutura e da espacialidade na obra de Mies van der Rohe. O objetivo é identificar sistemas e estratégias estruturais diversas ao longo do seu trabalho e entender sua relação com a evolução da concepção espacial de suas obras. Adotou-se como referência para esta análise dois períodos da carreira de Mies: o

10. Evaluation of abutment and perimplantar region deformation of implant-supported screwed prostheses: an study using strain gauges / Avaliação da deformação do intermediário e região perimplantar de próteses implanto-suportada unitárias parafusada: estudo através da extensometria
The dental implant depends on the supporting bone for its stability and functional longevity. Mechanical behavior and trabecular bone structure affect the interface with the implant. Such knowledge may provide a basis for improvements in the current implant function and design, decreasing bone crest resorption and failure at bone-implant junction. Adequate q

11. A formação das identidades urbanas em São Luís do Paraitinga e Bananal: patrimônio arquitetônico e religioso
The first occupation in Vale do Paraíba is connected to the search of Indian labor and gold, which later consolidates itself by the Portuguese conquest. Using Indian paths, colonizers went into the vale interior and, creating and new paths net consolidated settlements. In the XVIII century, migration and urbanization were intensified in this area because of

12. Efeito da altura do remanescente coronário, do tipo de reconstrução interna e do tipo de coroa restauradora na deformação e resistência à fratura de dentes anteriores tratados endodonticamente
The endodontically treated teeth restoration is important aspect in dental practice and involves many treatment options with varying complexity. The aim of this study was to evaluate the strain, fracture resistance and failure mode of endodontically treated teeth depending of the post and core type, the ferrule presence, restored with metallic or ceramics re
