The basic application of a tooth colored posts (functionally graded composite, zirconia and fiber reinforced composite) in the post endodontic restorative phase of a tooth is based on the usage of the correct post in a given situation. Many advantages of the tooth colored posts such as, its favorable esthetics, ease of use, their modulus of elasticity values that are similar to that of dentin and this can reduce the risk of fractures as well as stress concentration at the apex of root. It can increase their survival compared to teeth restored with metallic posts. The most complication of the colored post system is the deboning failures, but those posts allowed the retreatment of the deboning post. All studies evaluating the tooth colored post systems up to December 2011were included. Key words: Post, Tooth Colored, Endodontic Treated Teet
