Introduction

Endodontic therapy is the removal of irreversibly inflamed or necrotic pulp tissue from the root canals. Future contamination of the endodotically treated teeth is a major and primary concern because of the high chance of oral cavity contamination to invade the tooth after Endodontic treatment which can be prevented by restoring the tooth immediately with no delays. The placement of this restoration returns the tooth to normal function and esthetic and maintain it against any further destruction as it becomes weaker after the pulp removal. Due to structural and morphological differences between vital and non-vital root-filled teeth, restoration of these endodontically treated teeth can be challenging.⁽²⁾ consequently, the quality of both endodontic treatment and tooth restoration have a heavy influence on the treatment outcome and prognosis. Recently coronal restorations of the teeth are rapidly growing and increasing in number, making the decision of choice more difficult to the dentist to obtain a restoration with a good quality to reach the maximum effectiveness. The choice of restoration depends on several situations and factors including mainly the amount of remaining tooth and the type of tooth and this requires special considerations⁽⁶⁾ emphasizing that the prognosis of endodontically treated teeth is largely influenced by the postendodontic restoration and not only the endodontic procedure its self ^(7-9).
