The results showed heterogeneity in all comparisons , and higher bond strength to dentin was identified for self-adhesive cements .
Although the articles included in this meta- analysis showed high heterogeneity and high risk of bias , the in vitro literature seems to suggest that use of self-adhesive resin cement could improve the retention of GFPs into root canals
Because there are several ways to cement  glass-fiber posts ( GFPs ) into root canals , there is no consensus on the best strategy to achieve high bond strengths .
A systematic review was conducted to determine if there is difference in bond strength to dentin between regular and self-adhesive resin cements and to verify the influence of several variables on the retention of GFPs .
Comparison of regional bond strength in root thirds among fiber-reinforced posts luted with different cements.
AIM To compare regional bond strength in different thirds of the root canal , among glass fiber-reinforced ( FRC ) endodontic posts luted with different cements , using the push-out test . MATERIAL AND METHODS Sixty extracted human anterior teeth were endodontically treated with gutta-percha and AH Plus sealer . The crown portion was removed , and a dowel space was prepared . Prepared teeth were r and omly assigned to one of six groups ( n = 10 ) for luting glass FRC Postec posts , with one of the six cement systems ( Ketac Cem Aplicap , Relyx Unicem Aplicap , Variolink II/Excite DCS , Panavia F/ED Primer , C&B cement/All-Bond 2 , and Multilink/Multilink Primer A/B ) , using an alignment technique . Specimens were embedded in resin , and each root was sectioned into six 1-mm thick serial slices . A push-out test was performed to measure regional bond strengths and to identify the type of failure . RESULTS The highest bond strength values were found in the cervical third and the lowest in the apical third . Highest values were obtained using Variolink II , Panavia F , and Multilink resin cements followed by C&B resin cement and Relyx Unicem ionomer resin cement ; Ketac-cem ionomer cement showed the lowest value . CONCLUSION Highest bond strength values were obtained in the cervical third and with resin cements
The results showed heterogeneity in all comparisons , and higher bond strength to dentin was identified for self-adhesive cements .
