“…According to the results of the present study, sandblasting increased the bonding between fiber post and composite resin core but there was not any statistical significant difference between this group with control group ( P <.001). Some other studies concluded that sandblasting can improve the bonding strength of fiber post to composite core 2,15,19,21,23,31,44-46. Several reasons were introduced for this finding.…”

“…The composition of the glass-fiber surface is composed of the resin matrix, inorganic filler particles and the glass fibers 2. Some authors believed that sandblasting modifies the epoxy resin matrix and creates a larger surface area for bonding 2,19,21,47. However, sandblasting is considered as an aggressive pretreatment for fiber posts, because it significantly modifies the post shape 21,29,48.…”

However, sandblasting is considered as an aggressive pretreatment for fiber posts, because it significantly modifies the post shape 21,29,48. For this reason it is said that Al 2 O 3 particle size, as well as the application time and distance, may influence the bonding strength between fiber post and composite core.…”

PURPOSEDebonding of a composite resin core of the fiber post often occurs at the interface between these two materials. The aim of this study was to evaluate the effects of different surface treatment methods on bond strength between fiber posts and composite core.MATERIALS AND METHODSSixty-four fiber posts were picked in two groups (Hetco and Exacto). Each group was further divided into four subgroups using different surface treatments: 1) silanization; 2) sandblasting; 3) Treatment with 24% H2O2, and 4) no treatment (control group). A cylindrical plexiglass matrix was placed around the post and filled with the core resin composite. Specimens were stored in 5000 thermal cycles between 5℃ and 55℃. Tensile bond strength (TBS) test and evaluation using stereomicroscope were performed on the specimen and the data were analyzed using two-way ANOVA, Post Hoc Scheffe tests and Fisher's Exact Test (α=.05).RESULTSThere was a significant difference between the effect of different surface treatments on TBS (P<.001) but different brands of post (P=.743) and interaction between the brand of post and surface treatment (P=.922) had no significant effect on TBS. Both silanization and sandblasting improved the bonding strength of fiber posts to composite resin core, but there were not any significant differences between these groups and control group.CONCLUSIONThere was not any significant difference between two brands of fiber posts that had been used in this study. Although silanization and sandblasting can improve the TBS, there was not any significant differences between surface treatments used.

“…Por sus características intrínsecas, tienen una mejorada capacidad de adhesión a los cementos de resina, su resistencia a la fractura, su resistencia a la fatiga y su módulo de elasticidad han mostrado ser superiores (1,(7)(8)(9). Además, con el propósito de aumentar la fuerza adhesión entre los postes y los cementos, se han propuesto diferentes protocolos en los que se aplican combinaciones de tratamientos a la superficie del poste (9)(10)(11)(12)(13)(14). Se ha reportado que estos tratamientos, tanto químicos como mecánicos, producen un cambio en la matriz de los postes que influye en la adhesión de los postes al cemento de resina.…”

The purpose of this study was to determine the effect of different surface treatments on the bond strength between resin cements and quartz fiber-reinforced resin posts. Materials and methods: Sixty quartz fiber-reinforced resin posts (DT Light-Post™, Bisco™) were randomly divided into 12 experimental groups (n=5), according to the resin cement used (Biscem™ or Duolink™) and the surface treatment: Alcohol (control group), silanized, primer, sandblasted, sandblasted + silanized or sandblasted + primer. Cylindrical resin specimens were obtained using nanohybrid resin. The posts were cemented to the resin discs and push-out tests were conducted. Data were analyzed with ANOVA and T test for averages comparison and the Tukey HSD test with a 95% level of significance. Results: Biscem™ cement generally showed higher bond strength when compared to Duolink™ Significant differences were found between the control group and the sandblasted + silane and sandblasted + primer groups when using Duolink™cement. With Biscem™ cement, no differences between groups or with the control group were found.. Conclusion: Surface treatments on quartz fiber-reinforced resin poles seem to have no significant effect on the bond strength to resin cements, except when using Duolink™ cement with sandblasted posts and using silane or primer.

Evaluation of the effect of different surface treatments on the retention of posts: A laboratory study

Abstract: Air-borne alumina particle abrasion increased the retentive strength of all the type of posts used in this study. Treating the surface of the posts with resin-primer and ethyl alcohol produced no statistically significant difference in the retentive strength.
