Restoration of endodontically treated tooth containing wide or flared canal

There has been much anecdotal information and misinformation disseminated regarding the restoration of endodontically treated teeth, which has comprised the foundation for our restorative protocol. In the past, it was considered appropriate to place a cast post and core in every pulpless tooth without regard to the amount of remaining supportive tooth structure present. Recent developments in available ceramics, greater cosmetic demands by patients, and the advent of adhesive bonding techniques have caused clinicians to reevaluate their restorative protocol. This article reviews the current literature with regard to restoration of the endodontically treated tooth and presents a method for restoration and reinforcement using a combination of polyethylene ribbon and a prefabricated fiber post to create a post and core that is retentive, supportive, cosmetic and able to impart reinforcement to a structurally compromised root.
