Endodontics today offers great opportunities in term of simplicity and predictability of results. Today we can rely on a new approach based on reduced tooth structure removal so to leave more sound dentine in the restorative section of the tooth, and still achieve ideal endodontic treatment. The new instruments, the new ways of irrigating canals, three dimensional obturation offer a reliable way of treating teeth with a pulpal involvement in an easy and predictable way. Post-endodontic restoration shows problems and limitations which are very well known. Residual space geometry is not ideal for materials commonly used. Modern adhesives offer the chance to have better performance in restoration of teeth whether they are vital or non vital. A number of evidence state the importance of the coronal restoration of endodontically treated teeth in order to obtain the reestablishment of the system.
