Background Nowadays, the universal adhesive become more popular among clinicians due to its simple procedure. The application of universal adhesive on root canal dentin prior the self-adhesive resin cement may increase bond-strength between fiber post and dentin. The objective of this study was to evaluate the effect of different etching modes (etch-and-rinse and self-etch) to universal adhesives on push-out bond strength of fiber post. Material and Methods Thirty extracted sound human lower premolars were randomly divided into three groups based on adhesives systems prior to fiber post cementation; two-step etch-and-rinse (group A, Adper Scotchbond), etch-and-rinse universal (group B, Prime & Bond Universal), and self-etch universal (group C, Prime & Bond Universal). After adhesive application, self-adhesive resin cement was filled to the prepared root canal (Smart CEM2, Dentsply) for fiber post cementation. The adhesion between the fiber post and root canal walls was investigated using push-out test after 24 h water storage at 37◦C and the modes of failure were determined under SEM. Data were analyzed using two-way ANOVA test and the Bonferroni test was used to compare values among the three adhesives groups, followed by Tukey HSD for multiple comparisons. Furthermore, Weibull parameters were calculated for tested groups. Results Universal adhesive with self-etch mode significantly improved bond-strength compared to the two-step etch-and-rinse group ( p <0.05). The coronal part has higher bond strength than the apical section ( p <0.05). However, the bond-strength in two-step etch-and-rinse and etch-and-rinse universal was not significantly different. Self-etch mode showed higher bond strength compared to etch-and-rinse universal adhesive in the apical root section ( p <0.05). SEM revealed that all tested groups predominantly had an adhesive failure ( p >0.05). Conclusions Self-etch mode in universal adhesive system were effectively improved the push-out bond strength of fiber post to root canal dentin, especially in apical root section. Key words: Push-out bond-strength, self-adhesive resin cement, self-etch adhesive, total-etch.

“…reduces the root fractures [2]. Hence bonding between luting cement and post and bonding between luting cement and dentin may be improved through different post-surface treatments, careful choice of adhesives, and resin luting cement [8]. Surface treatments of post surfaces improve adhesion between post and resin-luting cement by allowing micromechanical and chemical retention between different constituents [9].…”

“…They contain 10 MDP (10-Methacryloyloxydecyl dihydrogen phosphate), a hydrophilic monomer with mild etching properties that enables it to be used with any etching technique (multimode adhesives) [12]. They combine the already existing "all-inone" concept with the versatility of being adaptable to metals, ceramics, zirconia etc [8]. There are very few studies on the effect of silane application on the bond strength of glass fiber posts.…”

Background: Endodontically treated teeth that lack coronal tooth structure may require the placement of a post to provide adequate retention of a core foundation followed by a crown. Glass fiber posts have become one of the most popular because of the similar modulus of elasticity to dentin.Aim: To evaluate the push-out bond strength of surface-treated glass fiber posts to intraradicular dentin using universal adhesives with and without silanization.Materials and methods: Thirty single-rooted teeth were prepared up to the working length in a step-back technique and obturated. Post space was prepared to the length of 10 mm. Based on silanization specimens were divided into two groups of 15 each. Clearfil Tri-S bond universalwas used as a bonding agent. The two groups including, Group 1 (without Silanization) (CTSBU):post-treatment -only 9%HF, and Group 2 (With Silanization) (CTSBU+S): post-treatment -9%HF followed by silane.RelyxU200 was used to lute the posts, and thesamples were divided into three parts (cervical, middle, and apical) and subjected to push-out bond strength analysis. Overall comparisons were done by analysis of variance (ANOVA), and pairwise comparisons were done by student t-test. The level of significance was set at p < 0.05 for all tests.Results: In all the root regions, group 2 (CTSBU+S) showed the highest pushout bond strength with statistical significance (p<0.05) when compared to other groups. In all the groups, the cervical region showed the highest bond strength when compared to the middle and apical regions which were significant (p<0.05).Conclusion: It can be concluded that the Silanization of the glass fiber posts showed to improve the bond strength and the cervical region has better bond strength among the three regions of the post

The aim of this study was to evaluate the effects of cleaning protocols on the presence of residues, open dentinal tubules, and bond strength of a self-etch adhesive plus a dual-cure resin cement to dentin in the fiber-post space. The methods for cleaning utilized were conventional irrigation (CI), rotary brush with continuous rotary movement (RB), and continuous ultrasonic irrigation (CUI). Sixty bovine incisors were used for fiber-post space preparation. Thirty roots were divided into three groups (n = 10) according to the cleaning protocols and submitted to scanning electron microscope to evaluate presence of residues and relative quantity of open dentinal tubules on dentin surface. Similar protocols were performed in the other thirty roots (n = 10) using a self-etching adhesive system (Scotchbond Universal) and a dual-cure resin cement (Relyx Unicem 2). After 6 months cervical, middle, and apical thirds sections of fiber-post space were submitted to push-out testing. To data ANOVA and Tukey's test were employed (α = 5%). RB and CUI showed the lowest presence of residues on dentin surface (p = .015) and the highest bond strength values (p < .001), regardless of the dentin third. CUI presented the highest quantity of open dentinal tubules in middle and apical thirds (p < .001). CI presented the lowest bond strength value of resin cement, regardless of dentin third (p < .001).Mechanical cleaning protocols, such as RB and CUI, presented better surface cleaning capabilities and higher bond strength than CI with dual-cure resin cement employed.The use of a mechanical cleaning protocol seems to cause appropriate condition on the root dentin surface. Mechanical cleaning of root dentin provided greater bond strength of the self-etching system with dual resin cement. Conventional irrigation did not provide adequate root dentin cleaning.
