This case report describes the treatment of a tooth with necrotic pulp and open apex (maxillary left central incisor). In this conventional multiple-visit apexification with calcium hydroxide was replaced with a simple two step apical barrier techinique using MTA. The treatment involved mild debridement of the dentinal walls with K files and repeated irrigation with sodium hypochlorite solution, followed by calcium hydroxide dressing for 1 week and lastly creating an apical plug with MTA. The objective of the treatment was to provide an apical stop for the root canal filling material.
