1. Influence of a Retentive Shoulder Design to Prevent Early Failure of Three Core Build-Ups
Resumo Este estudo avaliou a influência de um preparo retentivo em forma de ombro para prevenir a falha precoce de núcleos de preenchimento realizados em molares com 3 diferentes tipos de resina composta. Noventa e seis terceiros molares superiores hígidos extraídos de humanos, foram divididos em dois grupos (n=48) de acordo com o tipo de redução oclus

2. How biomechanics can affect the endodontic treated teeth and their restorative procedures?
Abstract: Endodontic treatment is a common dental procedure used for treating teeth which the pulp tissue has become irreversibly inflamed or necrotic as a result of the carious process or dental trauma. This procedure which involves mechanical and chemical preparation of root canal may affect several mechanical and physical properties of the tooth structure

3. Should my composite restorations last forever? Why are they failing?
Abstract Composites resins have become the first choice for direct anterior and posterior restorations. The great popularity is related to their esthetic appearance and reduced need of sound tissue removal as compared with former treatments. Several studies have demonstrated that composite restorations may last long in clinical service. In this review we dis

4. Reproductive biology and early establishment of Pinus elliottii var. elliottii in Brazilian sandy coastal plain vegetation: implications for biological invasion
Pinus is the most invasive woody taxon, exceeded only by herbaceous plants. This study reports the reproductive biology and early establishment of Pinus elliottii Engelm. var. elliottii, describing its invasive properties in a protected natural area of the Brazilian coastal sandy plains. We evaluated the seed germination and rain, longevity of seed viability

5. Avaliação longitudinal do selamento de dentina cariada em lesões profundas de cárie
Este estudo avaliou clínica e radiograficamente dentes com lesões profundas de cárie submetidos ao selamento de dentina cariada por 10 anos. Trinta e dois dentes permanentes foram submetidos à remoção parcial de dentina cariada da parede pulpar da cavidade, remoção completa da dentina cariada das paredes laterais (critério de dureza clínica), forra

6. Densidade populacional, padrões demográficos e dinâmica da população de perfilhos em pastos de capim-marandu submetidos a lotação contínua e ritmos de crescimento contrastantes / Tiller population density, demographic patterns of tillering and tiller population dynamics on continuously stocked marandu palisadegrass subjected to contrasting rhythms of growth
Tillering is a growth strategy that forage grasses developed during their coevolution with herbivores as a means of ensuring survival, perennation and productivity, which is strongly influenced by several environmental and management factors. Recent studies, focusing on tillering of tropical grasses, have contributed to the understanding of plant responses t

7. The effect of enamel etching on the in vivo marginal adaptation of indirect composite resin restorations luted with a self-adhesive material / Efeito do condicionamento acido do esmalte na adptação marginal in vivo de restaurações indiretas em resina composta cimentadas com material autoadesivo
In vitro studies have suggested enamel-etching before luting indirect restorations with the self-adhesive cement RelyX Unicem. However, there is no scientific proof that this procedure has any clinical relevance. The aim of this in vivo study was to evaluate the effect of enamel etching on the marginal quality of indirect composite resin restorations (inlay/

8. Preload and torque removal evaluation of three different abutment screws for single standing implant restorations
Several authors still consider the mechanical problems of fracture and component loosening as the main causes of failure of implant-supported restorations. The purpose of this in vitro study was to compare the preload of three types of screw for transmucosal abutment attachment used in single implant-supported prosthesis through strain gauge and removal torq

9. Influence of resin-composite formulation on the intra-oral degradation : in vitro study / Influencia da formulação de resinas compostas na resistencia a degradação intra-oral : estudo in vitro
Natural teeth, as well as restorations, are composed of materials that are subject to deterioration. Besides chemical, mechanical and thermo degradation, the formulation and post-cure composites network are dominant mechanism to determine the restorations longevity. The purpose of this study was to investigate the effect of materials formulation, light

10. Influencia do meio e tempo de armazenamento na resistencia a microtração de sistemas adesivos / Influence of time and storage medium in the microtensile bond strength of adhesive systems
The purpose of this study was to evaluate "in vitro" the microtensile bond strength of two adhesive systems applied to the dentin as a function of time and storage medium, as well as to illustrate, through Scanning Electron Microscope (SEM) images, the nanoleakage of the hybrid layer, which had its constituents evaluated by microanalysis (EDS). Eighty recent

11. O idoso na sala de aula : um novo ator
The rising of the elderly population in Brazil and in the world is a reality which is product of the significant decrease in mortality and fecundity, consequences of a considerable enhancement of life quality, thus provoking huge population oscillation and consequences which become challenges for society. According to data obtained in this research, in the F

12. Efeito do fluor de um sistema adesivo na resistencia de união e no desafio acido em dentina / Effect of fluoride containing adhesive system on microtensile bond strength and acid challenge on dentin
Despite of the advance in adhesive dentistry, it is not possible to achieve an ideal bonding between composite resin and dental substrate. Currently, a variety of adhesive systems have been used. However, any adhesive system is capable to hamper the marginal leakage, degradation, and secondary caries formation at dentin-resin interfaces in long-term. For tha
