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.

ABSTRACT Purpose The purpose of this study was to evaluate the effect of self-adhesive and self-etching resin cements on the bond strength of nonmetallic posts in different root regions. Materials and methods Sixty single-rooted human teeth were decoronated, endodontically treated, post-space prepared, and divided into six groups. Glass-fiber (GF) posts (Exacto, Angelus) and fiber-reinforced composite (FRC) posts (EverStick, StickTeck) were cemented with self-adhesive resin cement (Breeze) (SA) (Pentral Clinical) and self-etching resin cement (Panavia-F) (SE) (Kuraray). Six 1-mm-thick rods were obtained from the cervical (C), middle (M), and apical (A) regions of the roots. The specimens were then subjected to microtensile testing in a special machine (BISCO; Schaumburg, IL, USA) at a crosshead speed of 0.5 mm/min. Microtensile bond strength data were analyzed with two-way ANOVA and Tukey's tests. Results Means (and SD) of the MPa were: GF/SA/C: 14.32 (2.84), GF/SA/M: 10.69 (2.72), GF/SA/A: 6.77 (2.17), GF/SE/C: 11.56 (4.13), GF/SE/M: 6.49 (2.54), GF/SE/A: 3.60 (1.29), FRC/SA/C: 16.89 (2.66), FRC/SA/M: 13.18 (2.19), FRC/SA/A: 8.45 (1.77), FRC/SE/C: 13.69 (3.26), FRC/SE/M: 9.58 (2.23), FRC/SE/A: 5.62 (2.12). The difference among the regions was statistically significant for all groups (p < 0.05). The selfadhesive resin cement showed better results than the selfetching resin cement when compared to each post (p < 0.05). No statistically significant differences in bond strengths of the resin cements when comparable to each post (p > 0.05). Conclusion The bond strength values were significantly affected by the resin cement and the highest values were found for self-adhesive resin cement.

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.

Aim. The aim of the study was to evaluate, by means of the push-out test, the effect of the anatomical customization of the fiber post on the bond strength of a self-adhesive resin cement. Methods. Twelve endodontically treated, human, upper central incisors were randomly divided into two groups (n=6): control (glass fiber posts cemented with Relyx® U200) and customized (glass fiber posts anatomically customized with translucent composite resin cemented with Relyx U200). The roots were sectioned into three slices, cervical, middle, and apical, and photographed with a digital camera attached to a stereomicroscopic loupe. The images were analyzed by software, for evaluation of the cement line. The slices were subsequently submitted to the push-out test until the post had completely extruded, and the fracture mode was analyzed with a stereomicroscopic loupe. Results. The results showed significant differences between the groups in the different root thirds in relation to the area occupied by air bubbles (p<0.05). Bond strength, when all the thirds are considered, was 8.77 ± 4.89 MPa for the control group and 16.96 ± 4.85 MPa for the customized group. Conclusion. The customized group showed greater bond resistance than the control group and a more uniform cement layer.
