Sealing Ability of Esthetic Post and Core Systems.

AIM: To review the literature on the sealing ability of esthetic post systems with different cementation techniques.

BACKGROUND: An important factor for successful root canal treatment is the development of a coronal seal to the treated root canal system. Review result: The current literature describes promising results using fiber posts with a dual-cure, self-etch resin cement system. However, none of the published results describe a post system or cementation technique that achieved a homogeneous and tight coronal seal.

CONCLUSION: Fiber post systems appear to be favorable alternatives to metallic or ceramic post systems. Furthermore, dual-cure, self-etch resin cement systems represent superior alternatives to other cement systems.

CLINICAL SIGNIFICANCE: The clinician should be aware of the differences between various post systems and different cement systems to select and apply the most appropriate post and cement in each clinical situation.
