Abstract
Aim of the study: To compare the success rate of root end filling material using MTA( mineral trioxide aggregate) and zinc free amalgam in re-apicectomized teeth. Materials and methods: The study sample consisted of 30 patients having previously failed surgical endodontic treatment. The sample was divided into 2 groups, the 1st group treated with MTA root end filling, while the 2nd group treated with amalgam root end filling. The patients were followed up after 6 months to assess the periapical area both clinically and radiographically. Results: There was no statistically significant difference between the success rate of MTA treated group and that of amalgam treated group, although MTA has a higher success rate than amalgam treated group .the success rate of MTA treated group was (86.6 %) while the failure rate of MTA treated group was (13.3%), the success rate of zinc free amalgam treated group was ( 66.6%) and the rate of uncertain healing was (13.3%) while the rate of failure was (22%). Conclusions: MTA can be a good alternative to amalgam as a retro grade filling material, but amalgam is inexpensive, available ,and most of the dentist are familiar with the use of it.
