Department of Conservative Dentistry and Endodontics conducted a guest lecture on “Revascularization of necrotic immature permanent teeth – An Update" presented by Dr. C. Sooriaprakas, Reader, Dept of Conservative Dentistry and Endodontics, Meenakshi Ammal Dental College on 23.11.18 at Watson and Crick Hall, Saveetha Dental College. In the recent years, there is a paradigm shift in the management of necrotic immature permanent teeth, with most of these teeth being treated by revascularization rather than conventional apexification procedures. The current available evidence suggest the true pulp dentin complex is not being formed after regenerative endodontic protocols {REP], nevertheless it can result in continued root development that enable the tooth to survive for long time. This guest lecture highlighted the need for protocols that will enable good disinfection without causing damage to stem cells.
