1. Effect of the time-point of acid etching on the persistence of sealer residues after using different dental cleaning protocols
Abstract: Endodontic sealer residues remaining within the pulp chamber dentin after root canal obturation and cleaning with various solvents may compromise the appearance and the durability of dental restorations. Acid etching is routinely performed prior to application of dentine adhesive systems, but is effect on residual sealer material and the optimal ti

2. Effect of the application time of phosphoric acid and self-etch adhesive systems to sclerotic dentin
Objective: To evaluate the effect of application time on the resin-dentin bond strength (µTBS) and etching pattern of adhesive systems applied on sclerotic dentine. Material and Methods: A total of forty-two bovine incisors had their roots removed. The 1-step self-etch GO (SDI), the 2-step self-etch Adper SE Bond (3MESPE) and the 35% phosphoric acid (3M

3. Influence of ativation of self-etching adhesives systems on the microtensile bond strength and quality of hibrydization in dentin and enamel / Influencia da distancia da ativação dos sistemas adesivos autocondicionantes na resistencia de união e qualidade da hibridização em dentina e esmalte
The self-etching adhesives systems present high water content that are used as solvent for acid monomer ionization. The presence of the excess of this solvent in the hybrid layer can compromise its the formation, as well as to affect the polymerization of monomers producing bonding interfaces permeables. The use of self-etching adhesives in clinical situatio

4. Utilização do ácido ascórbico como tentativa de reverter o efeito da desproteinização com hipoclorito de sódio na dentina radicular, utilizando diferentes sistemas de cimentação / Redox potencial of ascorbic acid after sodium hypochlorite deproteinization to root dentine with different adhesive systems
The aim of this study was to evaluate the effect of ascorbic acid after root dentin treatment with sodium hypochlorite. A self-adhesive cement was compared with other two adhesive systems. The bond strength was also evaluated at different depths (coronal, middle, apical). Forty five single-rooted standard bovine teeth were divided in three groups. Specimens

5. The influence of different resin dental adhesive systems applied to human dentine in the face of an in vitro bacterial cariogenic challenge, in vitro / Influência de diferentes sistemas adesivos dentários resinosos aplicados em dentina humana frente a um desafio cariogênico bacteriano, in vitro
The aim of this study was to evaluate the in vitro behavior of three dental adhesive systems (DAS), namely the two self etching Clearfil SE Bond Kuraray Co (CSEB) and Xeno III Dentsply (X-III) as well as the three-step etch and rinse Multi-Purpose Plus 3M ESPE (SBMP), concerning the inhibition of secondary dentine caries in the face of a bacterial cariogenic

6. Degradação da interface de união utilizando diferentes sistemas adesivos em dentes deciduos e permanentes tratados endodonticamente : estudo in vitro / Bonding degradation in endodontic treated permanent and primary teeth using different adhesive systems : an in vitro study
During the endodontic treatment irrigant substances with the purpose of assisting the disinfection of the ducts are used, being the most used the sodium hypochlorite. These substances modify the teeth substrata, which is used in the formation of the hybrid layer and bonding of the adhesive systems to the dentine. The studies are controversial of the shear bo

7. Influência da delimitação da área adesiva no ensaio mecânico de microcisalhamento / Evaluation of adhesive area delimitation on microshear test
This study had as objectives to evaluate if the delimitation of adhesive area on microshear test is capable to modify the values of shear bond strength; to determine if this delimitation can modify the ranking of the analyzed adhesive systems and to correlate the found types of failure with the values of bond strength in each experimental group. The specimen

8. AVALIAÇÃO DE ADESIVOS AUTOCONDICIONANTES SOBRE A UNIÃO ADESIVA EM ESMALTE E DENTINA
The purpose of this study was to evaluate of bond-strength of self-etching adhesives on the in enamel and dentine. Forty third-molars were used to produces a flat enamel and dentin surfaces for the adhesion procedures. The occlusal surfaces of teeth were sectioned perpendicular to the long axis of the tooth in order to expose a flat dentin surface. In enamel

11. Influencia do sistema adesivo na microdureza do cimento resinoso dual na cimentação de pinos pre-fabricados de fibra de vidro em diferentes profundidades / Influence of adhesive system on hardening of dual-cured resin cement at different depths in restorations with fiber posts
The purpose of this study was to evaluate the Knoop hardness (KHN) of dual cure resin cements used to bond fiber posts at different regions of root canal dentin. Forty eight extracted roots of bovine teeth were used. After root canal treatment they were randomly divided into six groups of 8 roots each. Fiber posts were inserted with two different adhesive sy
