Unrestored endodontically treated teeth are structurally compromised and remain one of the greatest challenges to today's dental clinician. Over the years many post materials and designs have been evaluated for strength, stress to dentin, retentiveness, and esthetics. Because many types of posts are available, the requirements of each specific clinical situation must be carefully evaluated. A better understanding of how to protect remaining tooth structure and the use of scientifically based concepts of restoring endodontically treated teeth will help us to develop sound biomechanical design principles and reach satisfactory final restorations. This critical appraisal focuses on comparisons of different post systems; stress effects on tooth structure, strength, and flexibility; and retrievability after failure. Furthermore it addresses whether post reinforcement should be used in incisors.
