1. Evaluation of dentinogenesis inducer biomaterials: an in vivo study
Abstract When exposure of the pulp to external environment occurs, reparative dentinogenesis can be induced by direct pulp capping to maintain pulp tissue vitality and function. These clinical situations require the use of materials that induce dentin repair and, subsequently, formation of a mineralized tissue. Objective: This work aims to assess the effect

2. Análise de interfaces de sistemas restauradores diretos em esmalte e em dentina humanos
RESUMO O presente estudo visou caracterizar a interface entre resina e substrato dentário submetida aos processos restauradores convencional e autocondicionante, levando a observar a presença de gaps e infiltração dos sistemas adesivos nos substratos dentários. A análise foi realizada em dois substratos dentários: o esmalte e a dentina. Seis dentes h�

3. In vitro evaluation of the antibacterial behavior of a self-etch adhesive associated with chlorhexidine
Resumo Introdução A tecnologia adesiva vem se desenvolvendo rapidamente desde que foi introduzida há mais de 50 anos. O principal objetivo da adesão é alcançar um íntimo contato entre a estrutura dental e o material restaurador e fornecer adequada união entre o esmalte e a dentina. Objetivo A proposta deste estudo foi avaliar o efeito antibacteri

4. Effect of erosive challenges on deciduous teeth undergoing restorative procedures with different adhesive protocols - an in vitro study
ABSTRACT Objective: To evaluate the effect of erosive challenges on the tooth- restoration interface of deciduous teeth treated with different adhesive protocols. Material and Methods: Deciduous molars were cut mesiodistally, then embedded, abraded and polished (n=80). Samples were randomly divided according to the adhesive system used into: G1 (Adper Sing

5. Bioceramic/Poly (glycolic)-poly (lactic acid) composite induces mineralized barrier after direct capping of rat tooth pulp tissue
The aim of this study was to observe the histopathological pulp response following direct pulp capping of mechanically exposed teeth in rats with a composite of beta-tricalcium phosphate-hydroxyapatite bioceramic (BC) and poly (glycolic)-poly (lactic acid) (PLGA) material or a calcium hydroxide [Ca(OH)2] material, compared to BC alone and a negative control

6. Análise qualiquantitativa da permeabilidade dentinária do terço apical de diferentes grupos dentais / Qualiquantitative analysis of apical dentin permeability in different dental groups
This ex vivo study evaluated histochemically the dentin permeability of the root canal walls in the apical third of different human dental groups, analyzing the pattern of dentinal tubule distribution and the presence of sclerotic dentin in this region. Eighty teeth were used, being 8 of each dental group - maxillary and mandibular central incisors, lateral

7. Influência da dentina sadia e afetada por cárie na resistência de união de sistemas adesivos e cimentos de ionômero de vidro em dentes decíduos - estudo in vitro / Influence of sound or caries-affected dentin on the bond strength of adhesive systems and glass ionomer cements in primary teeth an in vitro study
The aim of this study was to evaluate the influence of sound and caries-affected dentin of primary teeth restored with different materials, regarding bond strength and nanoleakage. Seventy two primary second molars received standardized occlusal preparations were randomly assigned in two groups. One group was nominated as sound dentin [SD] (n=36), and the ot

8. Avaliação da associação de clorexidina com etanol na durabilidade da adesão à dentina / Evaluation of the adjunctive use of chlorhexidine and ethanol on the durability of resin dentin bonds
Both adhesive and collagen degradation have been regarded as major causes of resin-dentin bonds failures over time. Complete infiltration of hydrophobic resins facilitated by ethanol, and the presence of MMPs inhibitors within the hybrid layer would build the ideal interface, resistant to hydrolysis and enzymatic activities. This study examined the benefits

9. 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

10. Análise in vitro da penetração do corante azul-de-metileno na dentina radicular humana variando-se o método de impregnação . / An in vitro analysis of the methylene blue dye penetration in human radicular dentin with different methods of impregnation
The purpose of this investigation was to evaluate how different contact methods of methylene blue dye solution 0, 5%, pH 7 for 24 hours, have influenced, in the reading of the demarcation leakage by tracer agent on the root dentin of human teeth. This study assesses 6 different methods: the dye agitation using the ultrasonic Gnatus, the agitation with the ul

11. Avaliação da influência do laser de Er:YAG no selamento de cavidades de cárie radicular induzidas in vitro e restauradas com cimentos de ionômero de vidro / Evaluation of the influence of the Er:YAG laser on the sealing of in vitro induced root caries cavities restored with glass ionomer cements
Failures of root caries restoration such as microinfiltration and secondary caries are mostly due to the difficult to reach the lesions and to the types of substrate. Thus, there is a constant search for new dental materials and caries removal techniques in order to minimize or extinguish these failures. The aim of this study was to induce root caries in vit

12. "Estudo comparativo da resistência à infiltração que diferentes materiais resinosos utilizados na cimentação de retentores intra-radiculares oferecem à passagem de fluidos que atravessam a dentina" / Comparative study of the infiltration resistance that different resinous materials used in intra-radicular retainers foundation offer to the fluids passage that cross through the dentine.
This study objective is to evaluate in vitro, the resistance that different resinous materials have through the fluids passage cross through the dentine in the absence of radicular cementum. 60 human teeth given by FOUSP bank of teeth were used. The teeth were submitted to endodontic treatment according to Paiva s and Antoniazzi´s technique and stored in a
