Root canal failures occur at a rate of 10–15% (Wong 2004). When teeth cannot be treated appropriately by root canal treatment or retreatment, endodontic surgery is usually the last option considered for saving the tooth. These procedures consist of periapical curettage, root-end resection, root-end preparation and root-end filling material being placed at the resected apex so as to act as a seal between the periodontium and root canal system. Harty et al. in 1970 reported that the apical seal was the single most important factor in achieving success in such surgery. So to achieve a perfect hermetic seal an ideal root-end material is required. A root-end material also requires other properties such as biocompatibility, easy handling, stability etc. This article is an overview on the newer root-end or retrograde materials that have been used so far in practice.
