An immature tooth with pulpal necrosis and periapical pathology imposes a great difficulty to the endodontists. Endodontic treatment options for such teeth consist of conventional apexification procedure with and without apical barriers and revascularization. Calcium phosphate is a calcium silicate-based cement that exhibits physical and chemical properties similar to those described for certain Portland cement derivatives. This article demonstrates the use of calcium phosphates as an apical matrix barrier in root end apexification procedure. This case report presents apexification and follow-up of a case with the use of calcium phosphate as an apical barrier matrix.
