The aim of this in vitro study was to evaluate the adhesion strength of two new fiber post systems (FiberSite™ Post and Cytec™ Blanco Post) cemented with two different adhesive resin cements (Panavia™ SA and Maxcem™ Elite). Root canals of sixty extracted human mandibular premolars were prepared using ProTaper Universal™ rotary files (Dentsply Sirona Endodontics, York, PA, USA). The root canals were irrigated with 5.25% sodium hypochlorite (NaOCl) during instrumentation. After root canal preparation, the canals were irrigated with 2 mL of 17% EDTA (1 min), followed by 2 mL of 5.25% (5 min) NaOCI, and 2 mL saline. The root canals were dried with paper points and divided randomly into two study groups (n = 30) according to the type of post system: Group 1, FiberSite™ Post (MegaDental, Partanna, Italy); and group 2, Cytec™ Blanco Post (Hahnenkratt, Königsbach-Stein, Germany), with one of the two adhesive resin cements: Subgroup A, Panavia™ SA Cement Plus Automix (Kuraray, Osaka, Japan); subgroup B, Maxcem™ Elite (Kerr, Orange, CA, USA). Following thermocycling, the adhesion strength was evaluated using the push-out adhesion (bond) strength test. Fractographic analysis was performed using stereomicroscope. The data were analyzed using two-way analysis of variance (p = 0.05). The adhesion strength values of both the posts were significantly higher when cemented with subgroup B (Maxcem™ Elite). The highest adhesion strength value was demonstrated by group 1B (FiberSite™ post cemented with Maxcem™ Elite cement). The type of post did not have a significant impact on the bond strength values for either cement material.

SUMMARY Because there are several ways to cement glass-fiber posts (GFPs) into root canals, there is no consensus on the best strategy to achieve high bond strengths. A systematic review was conducted to determine if there is difference in bond strength to dentin between regular and self-adhesive resin cements and to verify the influence of several variables on the retention of GFPs. This report followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. In vitro studies that investigated the bond strength of GFPs luted with self-adhesive and regular resin cements were selected. Searches were carried out in the PubMed and Scopus databases. No publication year or language limit was used, and the last search was done in October 2012. A global comparison was performed between self-adhesive and regular resin cements. Two subgroup analyses were performed: 1) Self-adhesive × Regular resin cement + Etch-and-rinse adhesive and 2) Self-adhesive × Regular resin cement + Self-etch adhesive. The analyses were carried out using fixed-effect and random-effects models. The results showed heterogeneity in all comparisons, and higher bond strength to dentin was identified for self-adhesive cements. Although the articles included in this meta-analysis showed high heterogeneity and high risk of bias, the in vitro literature seems to suggest that use of self-adhesive resin cement could improve the retention of GFPs into root canals.

Aim: To compare the push-out bond strength and modes of failure of fiber post cemented with different adhesive resin cements. Materials and Method: Forty five single rooted teeth were randomly divided into three groups as, group 1- Fluorocore 2+, group 2- Rely-X U200 and group 3-G-Cem, according to the adhesive resin cement used. The roots were subjected to chemo-mechanical preparation and cemented with adhesive resin cement. The teeth were sectioned into slices of the different root thirds and tested for bond strength (push out). Results were analysed using Chi square, Mann Whitney U and Kruskal Wallis test was used to find the significance of study parameters between three or more groups, with p = 0.05 for statistical significance. Result: Push out bond strength of Fluorocore 2+ is significantly higher at coronal level than apical level. No significant difference observed between coronal, middle and apical levels in group 2 and in group 3. Conclusion: Fluorocore 2+ adhesive resin cement is best to use for luting the fibre post. Fluorocore 2+ forms better bonding with post as well as dentin proving its better efficiency clinically.

Abstract Self-adhesive resin cement is highly recommended for cementation of fiber post systems, since it binds chemically with calcium ions in the hydroxyapatite particles without surface pretreatments of dentin. Unfortunately, chelating agents that are used to remove smear layer reduce the calcium ion content of superficial dentin. This study aims to evaluate the effect of remineralization of dentin on the bonding strength of fiber post using the biomimetic remineralizing agent CPP-ACP in vitro. Such a study will provide evidence on the possibility of improving bonding strength by increasing dentin mineral content. At the same time, it should be supported by further clinical studies since it remains in vitro.21 freshly extracted single rooted teeth will be treated endodontically, prepared for post space, and divided randomly into 3 groups: EDTA+CPP-ACP, EDTA + NaOCl, EDTA alone. Fiber post will be cemented and push out bond strength will be measured for all groups. The expected time of study is 6-8 months.

Aim: The aim of this study was to evaluate the effect of desensitizer, temporary cements, dentin cleaning methods on shear bond strength (SBS) of self-etch and self-adhesive resin cements to dentin. Materials and Methods: Four hundred eighty buccal or lingual/palatine coronal portions of human molar teeth were mounted in the acrylic blocks. Teeth surfaces were prepared until the dentin was exposed. Specimens were divided into four groups. One group separated as control and three groups of teeth were treated with a desensitizing agent containing calcium-phosphate desensitizer (Teethmate Desensitizer, TMD), resin-based self-reinforcing monomer (Shield Force Plus, SFP) and 2-hydroxyethyl methacrylate and glutaraldehyde (Gluma Desensitizer). Two different temporary cement containing calcium hydroxide (Dycall) and zinc oxide based (Rely X Temp NE) temporary cement were applied to the dentin surfaces. Temporary cement was removed with one of three cleansing techniques: 2% chlorhexidine digluconate and glass particles containing agent (Consepsis Scrub), cleansing bur (OptiClean), and ıntra/extracoronal rotary brush (Starbrush). All groups were further divided into two cementation subgroups (Panavia V5 and Panavia SA). The SBS (MPa) was measured using a universal testing machine at 0.5 mm/min crosshead speed. The data were analyzed statistically with a four-way analysis of variance and Tukey’s Honest Significant Difference test ( α = 0.05). Results: Although SFP showed higher SBS, there was no statistically significant difference between other groups ( P > .05). There were no significant differences between temporary cements ( P > .05). OptiClean rotary bur showed higher mean SBS values in all groups. The dual-polymerized Panavia V5 showed the highest SBS values in all groups ( P <.05). Conclusion: Cleaning of dentin surface from temporary cement remnants with a silicon bur and dual-cure resin cement showed the highest bond strength values.
