Apical surgery MTA is the material with the most favourable out- come as a root-end filling material for apical surgery. MTA has been associated with significantly less in- flammation, cementum formation over MTA and re- generation of the periradicular tissue (Figs. 4a–f).2 Apexification In order to prevent extrusion of root canal filling material in immature teeth with open apices, MTA is used as an apical plug. The results of many stud- ies have shown that MTA induced apical hard tissue formation more often and its use was associated with less inflammation than with other test materials (Figs. 2a–g).4 Repair of root perforations Accidental perforation of the pulp chamber or of the root canal significantly changes the prognosis of the tooth. Perforation repair with a biocompatible sealing material such as MTA may save compromised teeth (Figs. 3a–e).5 Editorial note: A list of references can be obtained from the publisher. contact Dr Mauro Amato is a lecturer and researcher at the department of peri- odontics, endodontics and cariology of the University of Basel in Switzerland.
