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 .
Finite element analysis and bond strength of a glass post to intraradicular dentin: comparison between microtensile and push-out tests.
OBJECTIVE This study tested the hypothesis that the stress distribution and bond strength of glass posts to intraradicular dentin is influenced by the mechanical testing methodology . METHODS Thirty single rooted endodontically treated teeth were prepared for luting of tapered fiber-glass posts ( Reforpost , Angelus , Londrina , PR , Brazil ) with a conventional adhesive system and resin luting cement ( Adper Scotchbond Multi- purpose , Rely X ARC , 3 M ESPE , St. Paul , MN , USA ) . The teeth were r and omly divided ( n=10 per group ) into micro-push-out ( Mpo ) , hourglass- ( Mh ) and rectangular stick-shaped ( Ms ) microtensile testing groups before sectioning each root into five 1-mm-thick specimens . During specimen preparation for microTBS testing 46/50 stick and 4/50 hourglass specimens prematurely failed ; therefore , the Ms group could not be included in the mechanical testing . The remaining specimens were tested at 0.5 mm/min until bond failure . Stress distribution within each specimen type for the three mechanical test methods was analyzed by finite element analysis ( FEA ) . Qualitative analyses were carried out through Von Mises , XY and Sy criterion . RESULTS Mpo and Mh had a mean microTBS of 11.89+/-6.55 and 14.98+/-12.72 MPa , respectively , which was not significantly different ( p=0.1311 ) . The push-out test demonstrated a more homogenous stress distribution by FEA and less variability in mechanical testing . SIGNIFICANCE Therefore , the recommended testing method for determining the bond strength of glass posts to intraradicular dentin is by Mpo
