(TC17) Significance of Orifice Barriers on the Outcome of Non-Surgical Endodontic Treatment

Bacterial microleakage is one of the leading causes of failure in root canal treatment (1). Apical seal against bacterial microleakage is achieved through proper three-dimensional obturation of the radicular space, following chemo mechanical preparation (2). Coronal seal is achieved by adequate seal of the root canal system with a definitive coronal restoration. Type of coronal restoration, time of placement, and quality can have a direct impact on the coronal seal and the long-term success of the root canal treatment (3). While the coronal restoration is mostly dictated by the restorative dentist it is imperative for endodontists to ensure an appropriate coronal seal before referring patients back to their referring dentists to achieve the highest chances of success. Patients sometimes wait several weeks before going back to their dentist for a final restoration. Moreover, many general dentists do not utilize dental dam isolation for restorative work. The clinical significance of immediate placement of orifice barriers after completion of root canal treatment will be discussed highlighting the enhanced outcome of endodontic therapy, even in instances where definitive restoration is inferior or missing.
