The available evidence indicated that the coronal region of the root canal bonded better to the glass fiber post  than apical regions .
Phosphoric acid , hydrogen peroxide , and silane application enhance post ’s retentiveness .
In light of the current evidence , surface treatment strategies increase the bond strength of glass fiber post to dentine .
However , recommendations for st and ardized testing methods and reporting of future clinical studies are required to maintain clinical ly relevant information and to underst and the effects of various surface treatment of glass fiber post  and their bond strength with dentine walls of the root canal
The objective of this systematic review was to determine the influence of surface treatment of glass fiber posts  on bond strength to dentine .
Post-surface conditioning improves interfacial adhesion in post/core restorations.
OBJECTIVES To verify the influence of different etching procedures of the post-surface on microtensile bond strength values between fiber posts and composite core material s. METHODS 60 DT Light Posts were divided into 10 subgroups using five different chemical surface treatments and two composite material s to build-up the abutment . Chemical surface treatments including etching with potassium permanganate ; treatment with 10 % hydrogen peroxide ; treatment with 21 % sodium ethoxide ; etching with potassium permanganate and 10 vol.% HCl ; silanization ( control group ) were performed on the post 's surface . The build-up was performed using ( A ) Core Paste XP ( Dent Mat ) and ( B ) Unifil Flow ( GC ) . Two sample s of each group were r and omly selected to investigate the morphologic aspect of the post/core interface with a scanning electron microscope ( SEM ) . The remaining specimens were cut so as to obtain microtensile sticks that were loaded in tension at a cross-head speed of 1mm/min until failure . The statistical analysis was performed using two-way ANOVA and the Tukey 's test for post-hoc comparisons ( alpha=0.05 ) . RESULTS SEM examination showed an interpenetrating adhesion network between the treated fiber post-surface and the composite material in all the groups tested . The results achieved with potassium permanganate had a significant influence on microtensile interfacial bond strength values with both the tested material s. Post-superficial treatments enhanced the bond strength particularly of Core Paste XP . SIGNIFICANCE Etching procedures showed a similar effect on the post-surface and enhanced the adhesion of composite core build-ups as a result of micromechanical and chemical retention
