Introduction Nowadays, patients keep asking for minimally invasive dentistry and therefore demand doctors to do “all is necessary” to save their teeth. Endodontics is not a newer branch of dentistry but its materials, techniques and methods are in a continuous wave of development, forcing the practitioners to constantly adapt to themselves. Furthermore, restoration of endodontically treated teeth represents a small, but largely controversed side of endodontics. It is well-known that restoration with fiber posts and composite core material is one of the most well-documented and scientifically-supported technique available. However, the overall treatment plan should always precede the root canal therapy itself and placing a fiber post in an endodontically treated tooth must be guided by biomechanical concepts, not by empirical ones. This paper’s purpose was to review data from the current scientific literature in order to offer a more clear view of restoring endodontically treated teeth with fiber post and their most common failures, but more important the existing means to reduce the rate of complications. When evaluating the complications regarding the endodontically treated teeth restored with fiber posts, we should keep in mind what these complications are and how we can manage them more efficiently. The assessing data from the literature provided some types of complications frequently involved and some conditions and procedures to prevent them. Complications of Endodontically Treated Teeth Restored with Fiber Posts A great majority of studies acclaim as the most common failure of an endodontically treated tooth restored with fiber post as being the debonding, followed by the fracture of the post. [1,2] Debonding may appear at two different levels andmay be caused by the weak interface between root canal dentin and fiber post surface or post core and luting agent. What is more, the way the adhesive cement is handled and cured can decrease the strength of the adhesion. [2] In general, the great concern was always the adhesion to the dentin wall, because it was rarely observed a failure between post-core and cement. [3] However, posts should be used in some specific situation and should not become a general method of treatment, regardless of some tooth factors. It is advisable to rigurously review the functional and parafunctional forces that will affect the restored tooth, in order to take a proper decision in a endodontic treatment. [4] The biomechanical aspects of adhesive restorations in endodontically treated teeth were found to perform in a similar way to the functioning of healthy teeth, but there are still some unresolved questions regarding the preffered cavity design and restorative technique used to restore endodontically treated teeth. [5]As the second most common failure of restored endodontically treated teeth with fiber posts is the fracture of the post, authors always keep in mind to evaluate the fracture resistance and stress distribution. [6] The literature points to the fatigue fractures, caused by unfavorable occlusal contacts. [7,8] When compared to cast posts, some authors demonstrated through a finite element analysis that glass fiber post is always a better idea due to its homogeneous stress distribution. [9]
