13. 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/

15. Influence of the type of framework system in the adaptation and microleakage of all-ceramic crowns / Influência do tipo de sistema de infra-estrutura na adaptação e microinfiltração de coroas totais cerâmicas
The objectives of this study were to quantify the microleakage and the loss of marginal adaptation before and after cementation of all-ceramic crowns, with four types of infrastructure systems, and to compare these parameters. After approval by the Committee on Ethics in Research of Dental School of University of São Paulo, 40 human third molars received al

16. Análise da técnica de fundição rápida segundo a adaptação cervical de infra-estrutura de liga à base de Ni-Cr e expansões de presa e térmica de quatro revestimentos / Analysis of accelerated casting technique in accordance with marginal adaptation of Ni-Cr crown and curing expansion and thermal expansion of four investments
With the improvement of dental investments for accelerated casting technique, recent studies have demonstrated that the procedure can be considered safe for daily use in the dental laboratory. Thus, cast pieces can be obtained in less time, the prosthetic work as a whole can be speed up and costs are cut with no quality compromise. Even though, there are sti

17. Gap formation in composite restorations : evaluation techniques, effect of photoactivation methods and relantionship with bond strength / Formação de fendas em restaurações de composito : tecnicas de avaliação, efeito de metodos de fotoavaliação e relação com a resistencia da união
Gap formation in composite restorations has been characterized in this dissertation by way of evaluation techniques, modifying factors and the relationship between bond strength of the restorations and the dental structure. In Chapter 1 the objective was to compare the dye staining technique to Scanning Electron Microscopy (SEM) evaluation of gap formation i

18. Comparative study of the adaptation between metallic copings and alumina, in system In-Ceram, before and after cementation / Estudo comparativo da adaptação entre copings metalicos e de alumina, no sistema In-Ceram, antes e apos cimentação
The purpose of this study was to evaluate the marginal fit before and after cementation of metal and aluminium oxide In-Ceram copings, on bovine teeth preparation using two kinds of cement. Sixty bovine incisors were embedded in resin and the coronal portions of the teeth were prepared to receive complete crowns usin a 4103 diamond bur under refrigeration wi

19. Assessment of conventional and digital radiographic methods in the diagnosis of marginal fit of the implant-abutment interface. / Avaliação do exame radiográfico convencional e digital e digital no diagnóstico da adaptação entre implantes dentários e protéticos.
A Implantologia é uma das modalidades de reabilitação bucal, inclusive pela alta taxa de sucesso das próteses implanto-suportadas. No entanto, estão sujeitas a alguns problemas exclusivos, como o afrouxamento do parafuso e a fratura do parafuso de fixação. A adaptação marginal de um pilar protético sobre o implante é imprescindível para que muita

20. Microinfiltração e adaptação marginal de restaurações classe V simulando lesões de abfração / Microleakage and marginal adaptation of class v restorations simulating the abfraction lesions
Avaliou-se in vitro restaurações classe V, simulando a configuração cavitária de lesões de abfração, quanto à microinfiltração e adaptação marginal. Sessenta pré-molares superiores foram divididos em seis grupos (n = 10), variando a combinação restauradora: G1 = Ketac Molar Liquid/Ketac Molar Easymix, G2 = Primer/Vitremer, G3 = Adper Single B

21. Effect of resin and ionomer sealer materials on demineralization inhibition of occlusal pit and fissures, evaluation of enamel mineral loss and marginal adaptation / Efeito de materiais resinosos e ionomericos na inibição da desmineralização do esmalte de fissuras oclusais : estudo da perda mineral do esmalte e adaptação marginal
The occlusal surfaces are considered susceptible sites for the biofilm accumulation, which increases caries development. Pit and fissure dental sealants are recognized as an important adjunct approach for caries prevention in high caries risk patients. However, in the search for a material that has a good clinical performance, it should be considered the int

22. Effect of additional retention in microleakage and gap formation in gingival margin of class II resin restorations: evaluation before and after mechanical cycling / Efeito de retenções adicionais na microinfiltração e formação de microfendas na margem gengival de restaurações de classe II extensas, feitas com resina composta: avaliação antes e após ciclagem mecânica
Este estudo laboratorial comparou a microinfiltração marginal e formação de microfendas em restaurações de classe II extensas, feitas com resina composta com margens situadas em dentina/cemento, utilizando diferentes tipos de retenções adicionais na caixa proximal. Cavidades padronizadas MOD extensas foram confeccionadas em 40 terceiros molares human

23. Desajuste Marginal de Infra-estruturas metálicas de próteses fixas sobre implantes considerando tipos de pilares, materiais e solda a laser / Marginal misfit of metallic structures of total fixed implant supported prosthesis considering abutments, material and laser welding
The adaptation precision of metallic structures to implant abutments is a very questionable subject and the scientific literature lacks about the alloy that shows an adaptation closer to the ideal. This study had the proposal of: evaluating the vertical marginal misfit levels (in μm) using a digital microscope of one-piece and after laser welding metall

24. A study of the correlation between marginal fit and tensions transmitted to implants by one-piece metal castings - a photoelastic analysis. / Estudo da correlação entre adaptação marginal e tensões transmitidas aos implantes por estruturas metálicas fundidas em monobloco - análise fotoelástica.
Obtaining a good marginal fit of the prosthetic components is one of the main obstacles to the success of rehabilitation with implant-supported prostheses. It is not clear, in the literature, which misfit levels are considered clinically acceptable, but it is known that the absence of a perfect and passive fit may cause inadequate tensions on the osseointegr
