“…The TAP-RelyX group had the highest bond strength value and the DAP-BisCem group had the lowest bond strength value. The Ca(OH) 2 and TAP medication increased the bond strength of the RelyX resin cement when compared with the control group (p < 0.05). There was no significant difference among the Maxcem groups in terms of bond strength values (p > 0.05).…”

The aim of this study was to evaluate the effect of calcium hydroxide (CH), triple antibiotic paste (TAP) and double antibiotic paste (DAP) on the push-out bond strengths of three different selfadhesive resin cements. Forty-eight single-rooted human maxillary central incisors were selected. The crowns were removed and the root canals were performed. After the irrigation protocols, the post space was prepared. The teeth were then randomly divided into a control group (no intracanal medicament) and three medicament groups (n D 12 for each group). After three weeks, the medicaments were removed using 17% ethylenediaminetetraacetic acid, 2.5% sodium hypochlorite and EndoActivator agitation. The teeth were divided into three subgroups according to the fibre-post luting cement: Maxcem Elite, RelyX Unicem and BisCem. The specimens were sectioned and the push-out test was performed. One-way analysis of variance and Tukey's post hoc tests were used for statistical analyses. Regarding the type of cement, BisCem had significantly lower bond strength values than Maxcem and RelyX. There was no significant difference between the bond strength values of Maxcem and RelyX (p > 0.05). The TAP-RelyX group had the highest bond strength value and the DAP-BisCem group had the lowest bond strength value. RelyX and Maxcem had higher bond strength to root canal dentin than BisCem. The bond strength of BisCem, RelyX and Maxcem was not negatively affected by the use of DAP, CH and TAP as intracanal medicaments.

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...

Can intra-radicular cleaning protocols increase the retention of fiberglass posts? A systematic review

The presence of residues within the root canal after post-space preparation can influence the bond strength between resin cement and root dentin when using fiberglass posts (FGPs). Currently, there is no consensus in the literature regarding what is the best solution for the removal of debris after post-space preparation. This systematic review involved "in vitro" studies to investigate if cleaning methods of the root canal after post-space preparation can increase the retention of FGPs evaluated by the push-out test. Searches were carried out in PubMed (MEDLINE) and Scopus databases up to July2017. English language studies published from 2007 to July 2017 were selected. 475 studies were found, and 9 were included in this review. Information from the 9 studies were collected regarding the number of samples, storage method after extraction, root canal preparation, method of post-space preparation, endodontic sealer, resin cement, cleaning methods after post-space and presence of irrigant activation. Five studies presented the best results for the association of sodium hypochlorite (NaOCl) and ethylenediamine tetra-acetic acid (EDTA), while in the other 4 studies, the solutions that showed improved retention of FGPs were photoninduced photoacoustic streaming (PIPS), Qmix, Sikko and EDTA. The results showed heterogeneity in all comparisons due to a high variety of information about cleaning methods, different concentrations, application time, type of adhesive system and resin cements used. In conclusion, this review suggests that the use of NaOCl/EDTA results in the retention of FGPs and may thus be recommended as a post-space cleaning method influencing the luting procedure.
