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 .
The use of reinforced composite resin cement as compensation for reduced post length.
STATEMENT OF PROBLEM Cements that yield high retentive values are believed to allow use of shorter posts . PURPOSE This study investigated the use of reinforced composite resin cement as compensation for reduced dowel length . MATERIAL AND METHODS The retention values of  stainless steel posts ( parallel-sided ParaPost and tapered Dentatus in 5- , 8- , and 10-mm lengths ) luted with Flexi-Flow titanium-reinforced composite resin and zinc phosphate cements were evaluated . Single-rooted extracted human teeth with crowns ( n = 120 ) , removed at the cementoenamel junction , were r and omly divided into 4 groups of 30 sample s each . Different post lengths were luted with either Flexi-Flow or zinc phosphate . Each sample was placed into a specialized jig and on a tensile testing machine with a crosshead speed of 2 mm/min , applied until failure . The effect of different posts and cements on the force required to dislodge the dowels was evaluated with multiple analyses of variance ( ANOVA ) . One-way ANOVA with Scheffé contrast was applied to determine the effect of different post lengths on the retentive failure of posts luted with the 2 agents . RESULTS Flexi-Flow reinforced composite resin cement significantly increased retention of ParaPost and Dentatus dowels ( P<.001 ) compared with zinc phosphate . One-way ANOVA revealed no statistically significant difference ( P>.05 ) between mean retention of both dowels luted with Flexi-Flow for all posts length used ( 5 mm = 8 mm = 10 mm ) . Mean retention values of the groups luted with zinc phosphate showed a statistically significant difference ( P<.001 ) for the different post lengths ( 10 > 8 > 5 mm ) . Parallel-sided ParaPost dowels demonstrated a higher mean retention than tapered Dentatus dowels ( P<.001 ) . CONCLUSION In this study , Flexi-Flow reinforced composite resin cement compensated for the reduced length of shorter parallel-sided ParaPost and tapered Dentatus dowels
