Root-End Filling Materials:An Update on the Latest Materials:A Review

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