Ability Of Different Posts To Reinforce Endodontically Treated Teeth

Restoration of an endodontically treated tooth, because of the significant loss of tooth structure, often requires additional support from the root canal by means of a post-and core restoration. However, post may generate stresses which lead to vertical root fracture and loss of the tooth. Since post design, material used and the post space preparation has a significant influence on vertical fracture prevalence, broad investigation is in progress to find out the optimum procedure. Esthetic, functional and structural rehabilitation of a pulpless tooth are critically important to ensure a successful restorative outcome. In cases where most of the coronal portion is lost, a common method to restore such teeth is the use of a post and core, onto which a full crown is cemented. The post functions primarily to aid the retention of the restoration and to protect the tooth by dissipating or distributing forces along the tooth. On the contrary, the tooth is weakened if dentin is sacrificed to place a large diameter dowel.The main purpose of this study was to evaluate the ability of different types of posts to reinforce endodontically treated teeth.
