“…Various HF concentrations and etching times have been proposed for fiber post etching protocols. Utilization of a low HF concentration, approximately 4-5%, was suggested for 60-120 s etching times [11][12][13] . However, the high 9.6% HF concentration has been normally used with shorter etching times in the range 15-60 s 10,14) .…”

The purpose of this study was to evaluate the flexural properties and surface topography of fiber posts surface-treated with various etching protocols. Seventy each of three types of fiber posts: RelyX Fiber Post, Tenax Fiber Trans, and D.T. Light-Post Illusion X-Ro, were randomly divided into 7 groups: no surface treatment, surface treated with hydrofluoric acid (HF) 4.5% for 60 s, HF 4.5% for 120 s, HF 9.6% for 15 s, HF 9.6% for 60 s, HF 9.6% for 120 s, and treated with H2O2 24% for 10 min. The specimens were then subjected to a three-point bending test. Surface topographies of the posts were observed using a SEM. The results indicate that fiber post surface pretreatments had no adverse effects on the flexural properties. However, the fiber posts treated with high HF concentrations or long etching times seemed to have more surface irregularities.

“…In this sense, chemical adhesion alone still may not achieve a satisfactory fiber post/composite interfacial bond strength 8) . Hydrofluoric acid has been applied to etching fiber posts surface, and this procedure statistically increased the interfacial bonding strength between the posts and the composite 11,15,16) . However, this technique could lead to substantial damage to the fibers and resin matrix, affecting the integrity of the posts 10,15,17) .…”

“…In addition, application of the Co-Jet system could weld a silicate layer onto the fiber posts surface which was often followed by silanization. This approach could significantly improve the interfacial adhesion through achieving a chemical combination and micromechanical retention 16,19,24) . Besides, immersing the fiber posts into hydrogen peroxide could remove the epoxy resin of the surface layer, so that a greater surface area of exposed fibers is available for silanization and the space between these exposed fibers could provide additional micromechanical retention [25][26][27][28] .…”

The purpose is to evaluate the effect of UV irradiation on the bond strength between epoxy-based glass fiber posts and resin cement. Twelve epoxy-based glass fiber posts were randomly divided into three groups. Group 1 (Cont.): No surface treatment. Group 2 (Low-UV): UV irradiation was conducted from a distance of 10 cm for 10 min. Group 3 (High-UV): UV irradiation was conducted from a distance of 1 cm for 3 min. A resin cement (CLEARFIL SA LUTING) was used for the post cementation to form resin slabs which contained fiber posts in the center. Microtensile bond strengths were tested and the mean bond strengths (MPa) were 18.81 for Cont. group, 23.65 for Low-UV group, 34.75 for High-UV group. UV irradiation had a significant effect on the bond strength (p<0.05). UV irradiation demonstrates its capability to improve the bond strength between epoxy-based glass fiber posts and resin cement.

“…Usage of NaOCl with EDTA can remove smear layer and removing the smear layer provides better adaptation of material into dentin tubules (34,35).It's demonstrated that canal sealers and residuals disappeared during smear layer removal but inter-tubular and peritubular dentin were also demineralized. Irriagation solution can dehydrate dental wall during cleaning procedure and dehydratation might affect the bonding strength (14,32). Demiryürek et al(14) investigated the effect of different irrigation solutions on bond strength of fiber post and found that different acids (citric, orthophosporic or EDTA) and acetone based cleansing agent (Sikko Tim) increased bonding strength.The type of adhesive system can also affect the adherence of fiber post (13).…”

It's known that many factors such as root canal dentin or post surface treatment may effect the retention of post. The purpose of this in vitro study was to evaluate the effect of different surface treatments on the bond strength of fiber post with luting agent to root canal dentin. 75 extracted single root teeth were used in this study. The canals were prepared with rotary instruments and obturated by AH Plus and lateral condensation technique. After post space preparation, 75 fiber-posts (Rebilda, Voco) were divided into 5 groups and treated with one of the following surface treatment procedures: no treatment (control), silanization, etching by % 9.6 hydrofluoric acid, sand blasting with 50 milimicron Al2O3 and bonded (15 of each). After that, posts were bonded with dual polimerizing resin based luting material. The specimens were embedded in acrilic resin blocks and sliced from the apical, middle, coronal part of the roots. A push out bond strength test was performed by a universal testing machine at across head speed of 1mm/min. Data were analyzed with one-way Anova and Tukey tests. Although silanization showed the least and sanding the best bond strength, only statistical difference was found between silanization and etching (p<0.05) and between sanding and bonding (p<0.05). Bonding group showed the highest bond strength in coronal section, and sandblasted group in middle and apical section (p<0.05). The different surface treatment affected the bond strenght of fiber post to root canal dentin.
