title: Periradicular healing and apical closure of a non-vital tooth in the presence of bacterial contamination.
abstract: This case report addresses the periradicular tissue response and root-end closure of a maxillary central incisor in the presence of bacterial contamination. The implications for the control of bacteria through the use of calcium hydroxide and/or systemic antibiotic coverage are considered in the light of scientific evidence and clinical treatment.
