13. Avaliação da resistencia de união de sistemas adesivos e cimentos resinosos a dentina e aos compositos restauradores / Evaluation of bond strength of adhesive systems and resincements to dentin and restorative composites
The current concept of bonding to hard dental tissues is based on the infiltration of adhesive systems in enamel and dentin, in the so-called hybridization process. While the enamel bond has been considered a reliable procedure due to its uniform composition, bonding to dentin continues to present challenges. The objective of this study was to assess and dis

14. "Interação do laser de diodo de alta potência com a superfície radicular. Efeito na morfologia, na variação de temperatura e na adesão e proliferação de fibroblastos em cultura" / Interaction between high power diode laser and dental root surface. Thermal, morphological and biocompatibility analysis
The aim of this study was to analyze the interaction between the high power diode laser and the dental root surface through the temperature variation analysis (Step A), root surface morphological observation (Step B), adhesion and proliferation of fibroblasts cultured on the top of the root surfaces (Step C). Twenty-one uniradicular teeth were used in the 3

15. TÃcnicas de Interferometria Ãptica aplicada à medicina, odontologia e comunicaÃÃes Ãpticas
In the work described in this thesis, we used two different interferometric techniques, the coherent optical frequency domain reflectometry (COFDR), and the optical coherence tomography (OCT). Both techniques are based on the Michelson interferometer. They were applied to optical communications and to medical and dentistry imaging. We will give a general des

16. Tegumentary, skeletal and dental evaluations of the facial profile. / Avaliações tegumentares, esqueléticas e dentárias do perfil facial.
The purpose of this study was to radiographically evaluate the relations hip between lips, soft pogonion, maxilla, mandible and incisors in individuals with a balanced facial profile. Thirty Brazilian women aged 19 to 31 years were evaluated, from whom teleradiographs (lateral view) were taken in the natural position of the oriented head. The cephalometric a

17. Laser Ablation of dental substrates: enamel, dentin and composite resins. / Ablação a laser de substratos dentais: esmalte,dentina e resinas compostas.
Laser is now established as a suitable tool for the selective and precise removal of carious dental tissue. If correctly used, lasers minimize the losses of healthy tissue besides the comfort that it ean promote to patients. The knowledge of basic aspects of laser ablation of dental tissues and materials can lead to the development of a set of parameters tha

18. Microstructural variation in conodont enamel is a functional adaptation.
Recognition that conodonts were the earliest vertebrate group to experiment with skeletal biomineralization provides a window in which to study the origin and early evolution of this developmental system. It has been contended that the conodont skeleton comprised a classic suite of vertebrate hard tissues, while others suggest that conodont hard tissues repr

19. Bacterium-Dependent Induction of Cytokines in Mononuclear Cells and Their Pathologic Consequences In Vivo
Viridans streptococci are a heterogeneous group of gram-positive bacteria that are normal inhabitants of the mouth. These organisms are thought to contribute significantly to the etiology of infective endocarditis, although recently they have been implicated in serious infections in other settings. Another group of oral bacteria, gram-negative anaerobes, is
