Clinical evaluation of retention strength of two different adhesive systems on glass fiber⁃reinforced posts

Abstract

Objective To evaluate the clinical effect of two different resin cements on the glass fiber⁃reinforced posts. Methods One hundred and thirty⁃six teeth were randomly divided into two groups, with sixty⁃eight in each. Group A used Multilink N self⁃etch system and group B used RelyX Unicem self⁃adhesive system to bond fiber posts. Follow⁃up examinations took place at 6, 12 and 24 months after the placement. Results The success ratios of two groups were all 97% above and there was no significant difference between two groups (P > 0.05). Conclustion Multil⁃ ink N self⁃etch system and RelyX Unicem self⁃adhesive system all have good effect on glass fiber⁃reinforced posts bond⁃ ing.
