After endodontically treatment, the tooth needs to be restored. There is a lot of variety in material, shape, retention etc. of the post, fabricated now days. After a review in some different dental journals, we select some studies, which were based in the different ways of restoring an endodontically treated tooth. Some posts had better properties than some others, and some where specifically indicated to be used in some cases compare with the others post. Length, shape, material, force resistance, type of tooth etc. has a high responsibility to increase the longevity of the restored tooth. The type of post, retention, mechanical and esthetical properties, must be choosing based on the clinical indication.
