“…These cements have appeared on the market with a proposal to simplify the adhesive bonding technique, with the use of cement in one step 14 , eliminating the demand for pretreatment of the tooth and the restoration 5 . Clearfil SA Cement and Multilink resin cements are considered simplified RC, since the Clearfil SA Cement is one-step selfadhesive cement and the Multilink is applied in an association with a self-etching adhesive.…”

“…According to the treatment of dental tissue, the RC are classified: total-etch, self-etch or self-adhesive 2 . At present, all RC are based on the use of either an etch-and-rise or of a selfadhesive, however, application in stages technology is complex and considerably technology sensitive and thus may affect bonding efficiency 5 . The new self-adhesive, dual-polymerizing RC require no separate acid etching, priming or bonding resin applications to the prepared tooth surfaces before 6 .…”

Self-adhesive, dual-polymerizing resin cements require no treatment to the prepared tooth surfaces before cementation. Aim: The aim of this study was to evaluate the influence of curing mode on bond strength (BS) of three cementing systems to bovine dentin. Methods: The buccal enamel surfaces of 50 bovine incisors were removed to expose dentin and to flat the surface. The teeth were divided into five groups (n=10), which consisted of two resin cements (Multilink and Clearfil SA Cement) that were tested in dual-(halogen light for 40 s) and self-cured modes, and a control (RelyX ARC). Two cylinders of resin cements (1.0 mm X 0.75 mm) were prepared on each bonded dentin surface. After 24h at 37oC, resin cylinders were subjected to micro-shear testing in a universal testing machine (4411/Instron -0.5 mm/min). Data were statistically analyzed by two-way ANOVA, Tukey and Dunnett`s test (5%). Results: Multilink showed higher BS than those observed on Clearfil SA. Light-curing resulted in higher BS for both Multilink and Clearfil SA. When Multilink was light-cured, no significant difference on BS was demonstrated between it and RelyX ARC. Conclusions: The highest BS values were obtained in control group and light-cured Multilink resin cement.

“…The application of ascorbic acid is dependent on the increasing duration of exposure to the antioxidant [124]. Other examples are the use of ethanol [70,86], antioxidants such hesperidin, sodium ascorbate or rosmarinic acid [123]. Recently, a study of use of polidopamina at the post surface was found to be effective in improving the bond strength between resin cements and fiber posts without damaging the surface of the posts [57].…”

“…Crosshead speeds vary from 0.01 mm/min to 10 mm/min and various studies were performed to study the influence of test speed on the bond strength tests [70,75,85,98,135,145,146,[161][162][163][164][165][166][167][168]172]. Unlike controversial results of the macro-tests, when measuring micro-tensile bond strengths, some studies have reported that the influence of crosshead speed is insignificant [167,168].…”

In this paper, a review of the test methods for bond strength of glass fiber posts to dentin is presented. The main variables that influence the bond strength tests are related to substrate, to specimen properties, specimen preparation and test methodology. The impact of these variables on the test outcome is analyzed. The search was performed on studies published between 2007 and 2015. Most of the tests carried out, in the literature, were the push-out (75%), pull-out (13%) and microtensile (11,9%) tests, showing an inversion compared to the results found in studies published between 2005 and 2010, when push-out test was used in a proportion of 2% and microtensile test in a proportion of 67%. The push-out test emerged as a practical tool for evaluating the interfacial shear strength between fiber post and root canal walls.Fiber posts have been widely used in endodontically treated teeth in the last years. One of the advantages of using fiber posts is the use of adhesive bonding technique, which requires minimal intervention on the dentin surface. In addition, fiber posts have an elastic modulus similar to dentin, resulting in more homogeneous stress distribution along the root canal system. Thus, fiber post minimizes the risk of root fractures and lead to more favorable failure mode than metallic posts.The durability of restored endodontically treated teeth depends on many basic factors [1] including the amount of remaining coronal structure, restorative procedures and the materials used [2,3], which appear to be the key factors affecting the longevity of the tooth. Although low percentage failure rates and satisfactory clinical performance have been reported when fiber posts were used [4, 5, 6], pulpless teeth are still considered more vulnerable and susceptible to fracture in comparison to vital teeth [7].The clinical success of a recovery depends on the quality and durability of the bonding joint between the fiber post and the tooth structure. Therefore, it is fundamental that the test method used to evaluate the bond strength provides accurate information on the materials performance [8]. Reviews published in the decades of 1990 and 2010 [9-13] showed a relationship between the conditions for adhesion of post to the substrate, including cement application mode, post pretreatment and sample storage conditions, but only few discussed the variables that influence the bond strength tests. Downloaded by [Florida Atlantic University] at 16:14 06 June 2016 A c c e p t e d M a n u s c r i p t 3The bond strength tests might be influenced by many variables which include: the specimen design, the size of the adhesion surface area, the loading configuration and the type of materials [2,[16][17][18]. The high modulus of elasticity of a bonded composite, the thickness of the adhesive layer between the dentin of the root canal and the post, the format of post and the canal, among others, are variables that influence the stress distribution along the bonded interface [3,18,19] and consequently the outcome of the bond streng...
